Has anybody bookmarked any 2.0 vs 2.5 threads?

I've been through every page in the engine/transmission section and opened every thread that looked promising. I'm looking for a little more depth and don't want to start a new thread if I don't have to. Specifically, I'm looking for the street behavior of each.

The crux of my curiosity here: 2.0s seem more common, cheaper, and easier to get (2.5 has a crowd looking for big power). In order to make "real" power on the 2.0, we need a bigger turbo, which shifts the
powerband higher and introduces more lag = crummy street experience.

I'm trying to quantify the above impressions and evaluate whether these can be mitigated (flow, compression, etc), to what extent they can be affected, and how much they matter in the first place.

There is a really nice running wrx/2.0 for about what I'm anticipating paying for a 2.5 auction donor.

Thanks for any links.

TurboMac,
I am running a stock 2004 EJ205 2.0L with 100,000 miles I did do a pocket port, valve job and DGV delete, compression after reassembly 163-165. I am using JDM V37 twin scroll turbo and EL JDM header, 1000cc injectors, Cobb Accessport. 259whp 227ftlb torque 14lb boost and 285whp 258ftlb torque 17lb boost. The engine doesn't have the torque number you will see with a 2.5L but the engine is free reving spools up quickly with the VF37 I am very pleased with the performance of my track car.

Thanks Mitch. Can you give me an idea of what the boost schedule looks like with the V37? psi vs rpm?

Yes will pull some logs off the Accessport, the Dyno sheet is on my build thread.
