View Full Version : Just another LS in a Roadster. Final assembly after paint

:cool:Hello ALL!

I've been dreaming about building a roadster since the introduction of the MK II. I finally pulled the trigger in July and my kit arrives early next month. A little about myself. Degree in electronic engineering, followed by 20 years in the Air Force as an aircraft electrical and environmental systems craftsman. I retired in 2008 at the age of 44. I was always interested in machining work so I took a part time job at a local machine shop 5 years ago and I've been doing that ever since. I really enjoy building stuff and I can't believe they pay me to make parts.

Anyway, here's my planned build so far:

MK 4 complete kit
Body cutouts
IRS rear end
Powder coated chassis
LS 1 5.3L all aluminum engine with FiTech FI system
Tremec TKX 5 speed with a Quick Time bellhousing
Power steering
Hydraulic clutch
Brakes "????"
Wheels and tires "????"

I'm not looking to recreate a cobra. I want to build a hotrod that just happens to look like a cobra. I'm blacking out all the chrome and going with non-traditional wheels.

I purchased a complete rear end from a 2019 Mustang GT and that provided all the non kit items for the back end of the car including stock GT brakes and rotors. I purchased a motor from a local builder that specializes in GM motors and I ordered the trans, clutch, bellhousing from Forte's parts connection.

The photos will show you my progress so far. The first motor pick is how I received it from the builder and the rest show the changes I made. Upgraded the valve covers and creakoted them burnt bronze. The accessory drive system was cerakoted black to go with the blackout theme.

A big thanks to everyone that has posted their build, the info is very beneficial to all of us first time builders.

Jim

I haven't picked a color or scheme yet but I'm leaning towards the new Mustang Mach 1 color scheme. The wheels will be mat or burnt bronze. It'll have a single stripe with a bronze pin-stripe. However, all of this is subject to change once I'm actually ready to paint.

Welcome Aboard Fellow Dark Sider!

The LS platform is a fantastic starting point, but you already knew that.
Consider putting your battery up front since that all aluminum LS is so light.
Remember that these cars have a rearward weight bias much like the Porsche 911 RWD.
Also consider upgrading the front brakes to the Cobra Style brakes from the earlier generation.

Again, Welcome Aboard!

Congrats on your upcoming build. I too decided to go with an LS engine. My kit is scheduled to arrive some time in Oct '22. BPE LS3 530/495 with TKX should arrive around July '22. Currently sourcing wheels and all the miscellaneous items I plan on including. Look forward to watching your build progress.

Hey Jim! Great to see you started a build thread. Subscribed! Also, really good to have another F5 builder in the neighborhood. You’re building what I wish I had the skill and cojones to pull off. Awesome!

Give me a ring when your delivery arrives. I’m happy to come over and help you unload everything.

I will relocate the battery up front for weight and ease of wiring. I have a set of four piston calipers for the front that came off a Mustang GT but I’m not sure they will fit. I’ll look into it once the car is here. I haven’t ruled out the Willwood option because I really like the look but not so much the price and I think it’s over kill for a car that light.

Thanks for the link!

The paint was a no cost option and I have the complete build sheet. Adding paint could be a mistake if it starts to peel and chip off. Time will tell.

Yeah sorry I was most curious about the build specs since that intake is going to want to be paired with a serious cam and headwork for high rpm so I was curious what kind of animal you had assembled there.

The shop I bought the engine from “The Hot Rod Company” has been building engines for years and they ship them all over the US and Europe. They do all there own machine work. They port and polish heads with a five axis CNC machine and they balance and blue print each engine. They even balanced my crank with the flywheel. I told them what I wanted and they built it. I on the other hand haven’t built an engine in the last 28 years and then it was a 327 SBC. I’m relying on them to get it right. However, if there is an issue they are just on the other side of town. :D

I’ll post the spec sheet when I get a chance.

So far the most disappointing part of this journey has been the fact that a lot of the bits and pieces I purchased for this build come from China. Even brand name parts like AC Delco and GM. Do we make anything in this country anymore?

I got a call from Stewart Transport and they told me to call them March 1st for an update on my delivery.

That’s a Wilga that I built for a friend. I’m currently working on a 165” Hanger 9 Carbon Cub FX3 for myself. That plane is a monster.

I’ve noticed a lot of build thread photos with RC planes in the background. It’s a common theme amongst kit car builders.

My inventory is done. I have a few items missing and a few extra items that I’ll need to return, i.e. Wilwood peddle assembly. I guess they thought I wanted the passenger to have a set of peddles too.

The build is underway. Like many other's, I have a page and a half of POL items, so I'm working on five or six different things at once. Work until you need a missing part and then start on something else.

164020164021
I was able to borrow a body buck from another local builder and I added two shelves below the body to store the aluminum. This helps out a lot when working in a smallish garage.

164022164023164029164028
I spent some extra time deburring all the holes in the aluminum and body before installing the panels. I'm using a Noga deburring tool which makes quick work of it.

164024164025
I've read a number of threads that mentioned shortening the aft upper turnbuckle on the front upper control arms. I decided to do this as well. I took an 1/8" off each end and I didn't need to cut the rod ends, they didn't bottom out. I used my mini bench lathe and took minor cuts each pass.

I'm installing a hydraulic clutch and I haven't found any info on the install of the master cylinder. I assume it's just like the brake cylinders? Remove 5/8" from the threaded rod and install?

On to the next page!

When installing the drive shaft adaptor I had two bolts that needed to go on a diet. A quick turn on the lathe and they fit perfectly.

164061164062

I finally found a good use for this pole that sit's in front of the air handler in my garage. I made a vise mount out of a tube that fit over the existing tube. It works great and didn't take up any bench space.

Getting the fuel system and brakes sorted out. The front brake lines are in and the fuel tank and fuel filter/regulator are in. I went with a in tank fuel pump from Aeromotive and the fuel pressure regulator is from a corvette. I will also run the proper fuel filter near the engine. 164698164699

The front brakes were easy enough. As you can see I used a standard brake t-fitting versus the one supplied with the kit. This way the brake lines lay closer to the f panel. I will do the same thing in the back. I also plan on using a one piece brake line from the master cylinder to the t-fitting in the back.

164700164701164702

I’m missing a lot of parts so I can’t finish the front or rear suspension or the steering so I’m going to install the motor and trans next so i can sort out the wiring and cooling system. I’ll pull the motor/trans once the wiring and cooling are sorted and then install the drivers side, inside panel, clutch and brake reservoirs, and the remaining engine bay items.

03-29-2022, 09:49 AM
Jim, you’re clicking right along, making good progress. Nice choice on the T-fitting — it really snugs the break line in close.

If you can use a grunt to push/pull on your drivetrain install, don’t hesitate to give me a call.

After making lifting brackets that mount on the exhaust ports and making spreader bars for the load leveler chains, the engine install was nice and easy for a one man show.

164946164947164948164949164950

Now I can work out the trans mount and then onto the forward firewall from FFMetal followed by the wiring harness (my favorite part).

It's time to tackle the wiring. Having been an aircraft electrician in the Air Force, the wiring doesn’t scare me, however, that doesn’t mean I know what I’m doing this go around. The combination of a modern engine with EFI does complicate things a bit mainly because you have two ways of doing some tasks with the engine. After doing some reading it seams like the smart choice is to have the engine ECU handle the fan, fuel pump, and some system monitoring while the car harness handles the lighting, starting, and other engine monitoring. With that in mind, I decided to open up the harness and remove everything that’s not needed and also replace all the plastic wire loam with the split mess loam. I’m also replacing all or most of the bulky plugs with terminal blocks.

Power for the fuel pump will come from the EFI control system but the ground will still run through the inertia switch.

Not the OP, but there is a ton of space around the oil pan. The frame rails are 24" center to center so any normal car pan will fit fine, front or rear sump (though you should use rear). The only pans that may not fit would be the deep truck pans due to the depth, and the C5 batwing pans due to their outside width being 20.5". What pan do you have in mind?

Contact FFR and ask them for the LS install documents. They list the oil pan requirements. My original pan was too deep and I replaced it with a specific corvette pan they recommended. I also had to replace the power steering pump and brackets because it was interfering with the steering linkage. What engine are you planning to use? I can help you pick the correct accessory drive if needed.

If you don’t hear from FFR then send me your email address and I’ll send you a copy of the LS documents.

If you have the pan already you might as well just wait until its installed to make the decision. It is pretty easy to replace with the engine in the car, so you can take a look at how deep it hangs and make a decision.

I’m continuing with more dashboard wiring. I decided to use the Fuel Injection computer to run the fuel pump which freed up the car harness fuel pump relay for use as a Hi/Low beam control versus using the switch provided in the kit. In fact, I switched out all the kit supplied switches for push button switches that light up when pressed. I removed all the bulky harness plugs in favor of hard wiring and my dash will be a plug and play setup so it’s easy to remove if needed. I had to draw out all my wiring changes just to make sure I didn’t wire something wrong or muck it up. Anyway, here’s some in process shots. I should have it wrapped up early next week.

The dash wiring is coming along. I have most of the hard wired connections made but I’m leaving the wire loam off until after I function check everything. That may take some time because I’m still waiting on the light switch and head lights. I’m also going with a keyless push button start system which will get installed next. Here’s what it looks like so far.

It looks like the alternator and power steering pump will be in the way of the steering linkage. The LS instructions don’t mention anything about the accessory drive, you have to work that out yourself. If you buy a LS engine from Blue Print motors I’m sure they have the correct setup. However, they don’t make it easy for those of use going the DIY LS route.

Shouldnt need to. There oughta be plenty of clearance for the truck intake if you want to use it, especially if you are planning to have a hood scoop. This intake is about the same height as a truck intake and it fits without a scoop. Though I really should get some info on where FFR decided to locate the engine since my mounts are custom and could potentially be lower than where FFR put it.

I have no experience with FiTech; this is what the engine builder chose for my application, but so far I’m happy with the quality of the fit and finish. I just hope it runs as good as it looks.

If you’re looking for recommendations then seek out experience builders and users. I don’t want you to spend your money based on my limited experience.

Good luck!

After helping Chris with his Coyote install, putting the LS in was a piece of cake. I’m still working on the ECU harness but it’s getting close.
166978166979

I’ve been getting POL items in from time to time but they have managed to ship the wrong drive shaft and rear springs so I’m waiting on those items again. I’m also waiting on my MIK items which includes the rear upper rod end. :( So, not a lot of progress on the rear end. I did finish up all the hard lines for the brakes and clutch. As soon as my rear brakes show up I’ll get those systems bled.

166982166983166981

On the upside, I did manage to get the correct oil pan installed. Also, the bell housing has a lip the runs the full diameter of the housing, that needed to be cut off on the bottom because it was well below the 4” chassis rails.

I’m not sure what to do about controlling the electric radiator fan? I can use the thermal switch or the ECU, or both. I already need a water temperature sending unit for the ECU and one for the temp gauge. If I also use the thermal switch then I need to find another location to install it.

Anyway, the more you do, the more you realize there’s more to do.

On to the next step!

All the engine wiring is complete, just some tidying up to do after the first start. I added some heat shield/insulation to the outside of both foot boxes. I really wanted to protect and or cover the brake line that runs to the rear brakes. I noticed others have run that on the inside of the foot box but because I used a single piece of SS brake line to run to the back, I took the easy way out and ran it on the outside. I ended up going with the Tilton 3 chamber reservoirs versus the FFR reservoirs. I like the fact that you can see the fluid level from the outside and all three reservoirs are in one location. The last couple of things I need to do is make the power steering lines and the cooling lines. 167917167916167915167914167918

Bolting parts to the chassis is the quick and easy part of building this car. It’s the little things that take up so much time.

I’m on my second dipstick and tube. The LS motor mounts used a spacer between the mount and engine. This puts it in the way of a normal dipstick. I had to bend the second one like a horse shoe to get it to fit. I may revisit this before the body goes on.

I wanted to add a fuel pressure gauge to the fuel rail. Instead of ordering one I decided to machine the AN fitting that was already there.

The factory five throttle cable wouldn’t work for my setup so I ordered a throttle cable with a clevis on the pedal end and a barrel on the throttle body end. However, the barrel was the wrong size so I had to machine that part as well.

After spending several days trying to figure out why I wasn’t getting any spark or fuel, I contacted FiTech and we went over everything I had done up to that point. It was decided to return the ECU. I just learned that they reset the software and everything is working as it should and they are shipping it back to me. In addition to that, I also just received the last of my POL and MIK items,,,, ��! I’m currently working on installing the 5 wire to 4 wire adapter. I received that after I already hardwire the harness by removing all the connectors. Now I get to cut into the harness and install the adaptor.

I also received the wheels I ordered 9 weeks ago.

The issues with the ECU was actually user error I’m afraid. When I was updating the initial engine settings you have to save to ECU for each line item and I was doing it by the page. :o

I have steam lines ran in the back between each head and between the two at the front of the heads and that is also plumbed into the radiator. The way you run the radiator hoses will depend a lot on which water pump you use.

The car was delivered in March, first start in August, and ready for the first test drive in November. However, it’ll have to wait until the weather changes a bit. Not a record setting build but still pretty quick for a first time builder I think! It hasn’t been without issues like leaking brake lines, leaking power steering rack fittings, etc, but all in all not too bad. It would have been quicker if I’d stop making changes to the build. I’m sure none of you guys do that.

174757

I have all the wiring done with the exception of some minor tidying up and I decided to go with an electric emergency brake so that’ll have to be installed and wired in as well. Currently I’m installing the light switch, LED dimmer switch, and turn signal switch below the dash. I like the looks of a clean dash but I can always relocate them if I find it annoying. The four push button switches on the lower center dash are for the Horn, High Beam, Fan (manual control), and E Brake.

I can't tell from the photos; does the crank pulley sit above the 4" cross tube? Or would it, if the pulley OD extended toward the front of the car? The accessory kit with my crate engine extends much further than the crank pulley, but I haven't installed the engine yet.

Mike,

Thanks for the link to your build. That’s given me some more options for the E Stopp location. Initially I was planning to mount it on the transmission mount but now I’ll have to look into the trunk area as you did. I’m running an IRS so I don’t know if that gives me more or less room.

Thanks again,

Hello Bill,

There’s not a lot of integration between the engine harness and the car harness. The engine harness is pretty much stand alone as is the car harness. You have options as to which harness will run the fuel pump; I choose the engine harness for this task, and you of course use the car harness for engine start, lights, etc. Depending on the gauges you use will determine which parts of the harness you’ll use. I removed all the connectors and redundant wiring just to clean up behind the dash. It was just a mater of hardwiring everything in versus using connectors. I do have connectors between the dash and harness so I can easily remove that.

A lot of this will make sense once you get started. Don’t be afraid to ask questions once you get to this part of your build.

Just a quick update after stabbing the engine and trans today - I need to raise it about 3/4" to get the steel blast shield closer to the frame rails. I'm not entirely sure how to it but I see there are 3/8" aluminum spacers made for Coyote swaps and I may be able to use washers between the block and the mount to gain another 3/8". The good news is that my crank pulley and accessories do not interfere with my front-mounted ABS module.

It looks like the alternator and power steering pump will be in the way of the steering linkage. The LS instructions don’t mention anything about the accessory drive, you have to work that out yourself. If you buy a LS engine from Blue Print motors I’m sure they have the correct setup. However, they don’t make it easy for those of use going the DIY LS route.

I checked the measurements and I believe your PS pump will be in the way of the steering linkage. My PS pump sits higher and next to the water pump pulley and there’s about 2” of clearance.

Hope that helps.

I finally got the E Stopp installed. It took me a couple of weeks to finish this task mainly because I couldn’t decide on where to mount it. I settled on mounting it to the transmission brace. I machined a stand-off for the front mount and used aluminum L brackets for the rear mounts. This lifts the E Stopp 1 1/8”. This puts less of a bend in the cable and easier routing over the 4” round crossmember tube. I welded a bracket to the tube to support the cable exiting the E Stopp. I use the term “welded” loosely as I am not a welder. Anyway, now that this task is complete I can finish installing the parking brake cables and close up the parking brake handle opening.

After that I worked on the rear wiring harness. I removed all the plastic wire loom and installed the split mesh loom which matches what I did to the rest of the wiring. I also made a bracket to support the fuel lines going into the fuel filter/pressure regulator. Now I’m ready to install the final piece of aluminum in the trunk.

I didn't specify brakes on my order, trying to figure out what I'm going to do there.

I bought a complete rear end from a 2019 Mustang GT and that came with the brake calipers and rotors. I only paid $1K for the rear end (basically a drop out with the subframe) and that included everything I needed that wasn't supplied with the kit. I believe the rotors are 13" and the calipers are a single piston. My feeling is, if it's good enough for the GT then it should be good enough for the MK4. However, it's easy enough to upgrade if needed.

Being able to machine your own parts is a lot of fun and it’s also very satisfying. It doesn’t matter if you use a hacksaw and file or a bench top lathe and 3 axis CNC machine. I needed a bracket to hold my oil catch can to the back of the engine head on the passenger side. I didn’t want to mount it on the firewall because that’s tucked under the body and I wanted easier access. So, I drew up a simple sketch after some measurements and then drew it up in CAD.

I’m running the TKX trans with the shifter in the forward position of the stock location. I removed the interfering cross member then welded mounting tabs on it and then relocated it slightly aft. I don’t think it’s necessary to re-install it but why not if it’s easy enough.

Okay, so I spent too much time playing with the C6 convertible and no time on the Roadster. However, I recently sold the C6 and now it's time to get the Roadster on the road. I started by making a simple clutch pedal stop bracket and got it mounted. I added a piece of rubber hose to the 1/2" post to prevent metal on metal contact.

192107192108192109192110

Now that the C6 is gone I have room for the body and chassis in the garage. I was thinking about doing the body work but have since started looking for someone local to take on that task. My hope is to find someone that will knock the seams off, fill, sand, and then get the body in primer. Then I'll mount the body, doors, truck, and hood so I can drive the car while waiting for a painter. Anyway, there's still lots of little things to do on the chassis before I can all it finished.

I drilled a hole in the L bracket and then welded it on both sides. I'm thinking about making another one that is even easier to install and doesn't require holes in the 3/4 square tube; that was a bit of a pain to drill because of it's location. Anyway, thanks again.

Hi Jim,

"clamp" design instead?

I like what you did with your pedal. I ended up using the factory pedal because I’m also using a cable.

Anyway, I’ll build a test piece and show you what I’m thinking. 🤔

Here's the clamp on pedal stop I came up with. It's super easy to install and adjust with just one hand/tool.

193372193373193374193375

I just test fitted it on the trunk hoop because I didn't want to take mine off. I would use this one if I hadn't already drilled the holes for mine. This one is on it's way to OB6.

I'm sure this is a Happy Milestone for everyone building a FFR kit!!!!!

THE CARPET IS DONE!

It was actually a lot more fun than I anticipated plus there's a lot of instant gratification after every piece. I'm still waiting on additional carpet to finish the cubby divider but all the kit carpet is in.

I also swapped out the kit seatbelts for something a little smaller and easier to get in and out of.

I'm in the process of machining seatbelt flanges where they pass through the rear bulkhead. They will be my own design with no hardware seen once mounted.

I also trimmed the wheel arches and filled in the lip behind the arches. Once the weather warms up I'll pull the body outside and sand and undercoat the underside of the body. Once that's done I'll be ready to fit the body.

Jim your build looks great. Nothing like having an analytical mind to figure out the speed bumps of a build. This is a bit off topic, but we have a common hobby. I noticed in your opening page a large RC plane with canisters hanging from the ceiling. Do you fly much? If your buying planes of that size with canisters you have been flying for a while. They are not cheap. It's very easy to take a 35 or 40% plane out for flying and have something go wrong or a mechanical failure and have a $5000 day. But as all fellow RC pilots know if you're going to fly, you're going to crash. Some days you hang your head and do the walk of shame with trash bags in hand to the crash sight. I too like large scale RC and have been flying successfully since 2008. I don't fly nearly as often as I used to since I got my car. But this year I have promised myself to get back into flying. Can't wait to see your car all done. 198173

Looking good, Jim. I like the border around your cubby opening. I’ll need to get a closer look at that when I see it in person next time. I assume you fabricated it? Also intrigued to check out your seat belts. Let’s go for a drive….soon! :D

I’ve been flying a little bit of everything for decades but now I fly mostly contest gliders. The large scale Wilga you see hanging in my garage is a plane used to tow scale gliders.

The club I belong to has a segment of the club that likes and fly's gliders. They use a 40% cub as a tow plane. I myself have a couple of powered gliders. No tow plane needed but of course they aren't as light so shorter flight times, at least the unpowered time. But then power back up and do it again. I find gliders so relaxing.

I came up with my own design for the shoulder seat belt trim rings. I like the "No Hardware" look. What do you think?

These are photos of the first two ops.

Here I've added the belt slot and drilled and counterbored the holes for the rivets. As you can see I'm using a tab mounted to the 3/4" tube to hold them in place.

I have had the body on and off a few times trying to get the correct fitment. I even enlisted the help of a fellow builder Chris. The first thing I learned is; the body is not symmetrical so don't try to make each side fit exactly like the other. The second thing is; I'll have to adjust the radiator mount to get the spacing correct for each front wheel arch. I also had to trim the back and side trunk panels so the body could slide forward a bit to get the correct fitment of the door opening and striker plate. My question is: does bulb seal get added to the lowest step on the trunk floor between the trunk side pieces? If I missed that in the manual then by all means tell me to look again!

Here's the progress so far. The underbody is painted and the side louver opening are cut to the proper size and location; for the most part. 200991200992200993200994

Thanks Jeff K for providing a side louver pattern so I could make a router template.

Yes, it gets bulb seal.

Here's the body progress so far:

1. The body is moved forward for the correct spacing of the door opening and door striker plate.

201649201650

However, moving the body forward and opening up the factory holes for the roll bars has produced a large gap forward of the roll bars. Is this normal?

201651201652

2. The front of the body was moved over. Measured from the upper shock tower to the wheel arch. The difference now is less than a 1/16th".

The hood opening is not centered on the upper 3/4" tubes. I believe this is normal and a non issue with all the adjustment you have with the hood hinges.

3. Light wiring is almost complete. I'm using Deutsch connectors.

Now it's on to the most feared part of the build, or dreaded part of the build...... Fitting the doors, hood, and trunk.

So true. I think you actually build this car twice because of how many times you take something off and then put it on again.


Looks great Jim. I have to say that's the part of the build I'm looking forward to least. But seeing yours all fitted gives me some inspiration.

I hear ya! Just knock it out one piece at a time and before you know it,,, it’s done. I decided to wrap the headers with heat shield tape so shortly after that video I have the car back on jacks and I’m removing the exhaust system. It’s much easier to do with it out of the car.

I finally picked a color and I dropped the car off at a local paint shop here in Spokane. It’s called Shark Gray Metallic.

The car is finally painted and ready for final assembly. HOWEVER, after picking it up from the paint shop I noticed they moved the sides of the car outward from where I initially set it up. That meant my side pipes where a little too close to the body. I ended up adding a 1/4" spacer in-between the header and side pipe. I also machined new side pipe brackets that not only moved the pipes away from the body but also filled the gap between the bracket and exhaust hanger. BTW, mine where spaced different from left to right so I made different size spacers. I know the rubber hanger can handle the flex but why not make them to fit if you're making them anyway.

First, a sneak peek of the color.

Here's a look at the original bracket and the new brackets I machined.

For the GM folks it's called Shark Gray Metallic and for the blue oval folks it's called Fusion Gray. I'm so close to being done,,,, kind-a sad really.

Winter is just around the corner here in the PNW so there's no graduation until next Spring.

Well I think that color may have entered my short list, and given my build, I'll go with Shark Gray. I've been looking at different gray or gunmetal colors, and this one is stunning. Can't wait to see it in natural light.

I'm about 95% there. I still need to set the final ride height, finish the lower door trim, and some minor trim work around the hood opening. For now, I have it on rollers and pushed next to the wall in the garage so I can park my daily driver during the winter months.

It's taken me three years to finally figure out how to increase the size of your photos. Now I'm going back through my thread and changing all the photos.

Thanks guys! I can hardly wait until it's parked out in the sun, the garage photos don't do it justice. I'm so close to finishing this car that I'm already looking for another project. Not necessarily a kit car project either.
