So, I've been doing some research and I`m really stuck on which motor and other components are best for my 03 2.5 RS all tips and suggestions will be EXTREMELY helpful and looked into carefully!
Find many great new & used options and get the best deals for 2004-2005 Subaru Impreza STI EJ207 Engine Version 8 VF37 Turbo 2.0L Motor JDM V8 at the best online prices at eBay! Free shipping for many products!
And no Subaru 5 speed will hold the power when you're pushing it, so you need an STI 6 speed.
Dallas JDM Motors. 6 Speed Manual Transmission. make Supersized seem small. Get images that. Arlignton, TX 76011. 827 Avenue H East #213. labor (NO EXCEPTIONS). Photos are of actual item .
Clutch kit to hold big power: $750+++
Sti wiring harness $several hundred
Having Iwire or another company merge your wiring with the STI's: $1500+
You probably want to stop, so a set of brembos, quality pads and rotors: $1200+
Wheels and quality tires that clear your brakes $$$
Fluids, timing belt, gaskets, sensors, misc parts, etc. Easily $1000, could be significantly higher
Estimate your car will be down for a few months.
And so on. What I'm trying to illustrate is you can very quickly exceed the cost of an 04-07 STI, and still have a car that you can't sell for anywhere close to the money you put in.
Don't get discouraged, but just know that financially it may make more sense to start with a factory turbo charged car and build that up.
For example, in my area (Greater Seattle area) there are always WRX's needing an engine or trans or both, for $2k-$4k. Hell my friend just tried to offload his running and driving WRX 5-speed wagon (rough body) on me for $2500. I just don't need 3 turbocharged Subarus lol.
My favorite engine is the ej22. You can take an old 2.2 block and put turbo heads on it for a super cheap, decently fast motor. I ran 18 psi on a 2.2 block with 2.5 heads that I modded for turbo oil return, it was all old 90's non turbo stuff. If I had put a new oil pickup in it I'd still be running it today.
That's probably about the limit for that setup, but cost/power ratio can't be beat. If you have loot get the aforementioned ej207.
Have you considered engine management?
