1. Will 17" Mustang wheels clear the intended Wilwood 12.88 brakes?
2. What about mini spare wheel/tire? There are lots of them available!

Don't want to scratch up new wheels.

But before I do that, I’m determining whether I should add any insulation to the engine bay compartment on the aluminum panels? I’ve read all the blogs talking about what kinds of insulation to use, but that’s after someone has already decided to do some insulation.

And, I have already insulated for sound deadening the entire cockpit area, including inside the foot boxes.

My question is more to whether it’s even necessary? Also, I’ve noticed engine bays with powder coated panels, not getting any additional insulation. I can see not wanting to put any insulation on those beautiful powder coated panels.

So, again, really necessary? ]]> ThickCobra https://v1.thefactoryfiveforum.com/entry.php?1341-Engine-Bay-Insulation GRADUATION DAY!!!!!

I got plates for my roadster on 4/25/25. PIcked up the kit on 6/20/09 - 15 years and 10 months.

Here it is. Will try to list the mods another time as they are extensive.

4.6L V8 Supercharged, IRS, T56 6 speed.

As many find, life gets in the way of the dream including 4 kids, working in NYC everyday with late nights, and walking away from the project when issues seem unsolveable.

Thanks to both forums, the many friends I made along the way, all the great vendors, my families patience and Sergio who inspired me to pick this engine combo.

Here is my baby.

In NJ there you need to complete a build log detailing how the build took place, show all receipts, pictures, show engine serial numbers, FFR frame numbers, etc. You then need to take the vehcile to a special inspection station where they review Reconstruction/Specialty Constructed Vehicles including Salvage vehicles.

The inspection station was County Ave and Secaucus Rd, Secaucus, NJ

It took me a long time to get here, not only the build, but I used a donor vehicle. My bad was that I never took the donor title and put it in my name. When checking with DMV on my build log they mentioned I needed a title in my name. So this should be easy, except when I got to DMV they said the title was stolen and not in the system. I got it from an Insurance Auction so was pretty sure it was good. Went to another DMV and got someone to work with me and advised I needed to call the sate of issue of the donor title (MS). I called and got someone and advised the title does not exist and its not real. Called back got another person and they took the time to look in the local MS system and found the title. It was never put in the national registery. This took about a month to happen. Then I went to DMV and everytime I was there I got a different reason why the title was no good. I eventually got it all squared away and the title in my name. I submitted the build log and waited. Weeks later I got a call that I was good to go and had to pay taxes on the receipts I submitted. Fine, whatever, paid approx $800 to NJ and was told I could schedule an inspection.

The inspection station is different than when I had helped a fellow builder years ago. They didn't put it on a lift and did not check emissions or measure the sound of the exhaust. The biggest issue was the engine number. The engine I have does not have a block number. The tech hooked up the OBD2 and got the vin from the computer and signed off on the engine.

The main items they checked:
lights, high beams, directionals, wipers, reverse light, break lights, driving lights, mileage on odometer, and frame number.

The inspection took about an hour and they signed off on it. They did ask for the Vin Plate that FFR provides when you buy the kit. I had it with me as the FFR number will become the Vin #. They said I should have attached it to the car in the engine bay. I told him I would do it as soon as I got home.

A very happy day. I now wait for the title to come in the mail, then I can register it and take it to the NJ standard inspection station all cars go to.

This is because the computer collects information while running and may be wiped out if you cut off power completely.

If this is accurate, does it mean I can’t use a cut off switch?

BTW, I appreciated all the responses on my heater hose question. ]]> ThickCobra https://v1.thefactoryfiveforum.com/entry.php?1337-Cut-off-switch-with-coyote-GEN-for-motor FFMetals Extended Firewall Questions https://v1.thefactoryfiveforum.com/entry.php?1336-FFMetals-Extended-Firewall-Questions Sun, 09 Mar 2025 22:12:19 GMT I've purchased the FFMetals Extended firewall for my MkIV roadster.

Before I start cutting holes in this lovely piece of aluminum. I'd like to know if the stock locations for items like the heater core are ok or if I need to modify the locations of such things to make other pieces fit properly. And do any of the heater core pieces conflict with the back of the engine. I'd like to have a functional glovebox, though I understand I might need to heat up the plastic of the glove box to modify it's shape. I'd like to avoid, as much as possible, doing such things.

Are there any fit conflicts with the Extended firewall and a Coyote engine?

First the particulars.

-Mk IV Cobra Roadster
-IRS
-Gen 3 or better Coyote planned
-TKX 5 Spd Trans planned

After building a largish chassis dolly, I started my build in June of 2024 working fairly steadily and documenting my work on my youtube channel here: [URL="https://www.youtube.com/channel/UCJ1_yPX6wW6apgupwJqEqqw"]J6 Cobra Build[/URL] don't forget to like and share.

The build has been smooth thus far with only a few head scratchers to slow me down. I felt well prepared as I attended the build class at Mott Community College in Livonia, Michigan a few years back. I'd say that was a wise investment. If considering one of these kits I highly recommend it.

Thus far I've modified the front upper control arms as suggested in the forums. Shortening the rear link to bring the measurements to spec as indicated in the assembly manual. I ended up doing much of this with a hacksaw and a grinder. That was FUN. FFR recomended to NOT modify the arms but many here said it was a good idea and I didn't want to pay someone else to do it later. SO BOLDY I proceeded.

I had a little trouble with the rear differential. At first the rear passenger side mounting bolt did not thread in to the mounting ear. Even though I had tested everything prior to lifting the diff into place. After consulting the forums a bit and reading some "sketchy" advice, such as filing the bushings out (don't modify your bushings), I decided to just loosen the front mounting bolts up enough to allow the diff to move around a bit in the chassis. I then removed the troublesome bolt and the rear half of the bushing along with the steel sleeve. I discovered the bolt threads had a small burr on them which I filed down. I then partially reassembled the bushing and sleeve assembly barely inserting the steel sleeve into the other half of the bushing. Just enough so I could use the bolt to pull the rest of the bushing into the chassis. It worked like a champ. So if your stuck with what you think is an misaligned diff. just leave things installed, but loose, and get everything started in then torque all the bolts as needed. I have a video explaining the evolution of this particular problem coming.

I've purchased the Extended Firewall from FFMetal and found it to be of excellent quality! If anyone reading this has any insights on where to cut holes in this piece for the heater core, Fuel pressure regulator and any other helpful info I would greatly appreciate it. Particular when it comes to fitment of the engine. How much space do I have to work with?

I should explain the name of my youtube channel as well so people don't get the wrong idea. I have a large family. 6 of us in fact and we all have "J" names. Thus J6 Cobra Build. I designed the logo so enjoy.

You'll hear some great music on my youtube channel. Thats my sons band "Forearms?" Available on Apple Music, Amazon Music and Spotify. The Cobra shares space with the band so Therefore I get to use there music on my videos. ]]> Jmatuk https://v1.thefactoryfiveforum.com/entry.php?1335-J6-Cobra-Build Engine Install https://v1.thefactoryfiveforum.com/entry.php?1334-Engine-Install Sun, 05 Jan 2025 00:03:53 GMT ---Quote (Originally by Jim Doak)--- Some friends and fellow Cobra owners/builders/enthusiasts braved the weather today and drove up to our house to...

He purchased a Factory Five Mk IV complete kit as well as custom wheels for the car as something to look forward to, he called it his carrot. No engine or transmission was purchased. It was purchased through his company and was delivered to a storage building where everything sits, untouched, from that time on. Given that I have neither the technical skill nor the interest in assembling a kit like this I have been searching for interested parties in my area (North Country New York) who would be interested in taking this off my hands. Alas, to no avail.

This community has seemed to me a good place to solicit advice for how to best find a buyer for this as-yet unassembled beauty, hopefully someone who would enjoy the assembly and use of such a vehicle. It would be trading at a discount, and delivery could be discussed. Full paperwork is present and none of the boxes which were delivered were ever opened, everything is still numbered and complete from the original delivery. Anyone know what door I should knock on next? ]]> StLawrenceRestoration https://v1.thefactoryfiveforum.com/entry.php?1330-Looking-for-Buyer-for-Mk-IV-Complete-Kit-plus-Custom-Wheels
