hey just caught wind of this thread.

DONT SWAP IN AN EJ25. An ej18t built like mine will walk N/A RS's with only 6lbs of boost.

Here is my setup. Its cheap, effective, fast, and reliable ( for now )

EJ22 heads (pretty sure they are ej22e not ej22t heads)
EJ18S block (very strong block, cylinder walls are thickest of all subie motors)
EJ22 headgaskets

Overall a 9.1:1 CR

WRX exhuast manifold.
WRX waterpump (needed to clear the manifold)
ERZ catless uppipe
TD04 turbo (anything bigger wont spool till after 4k)
Custom FMIC (buy an ebay fmic kit...its like 250 shipped!)
4:1 FMU
Stock injectors (cringe!)
HKS downpipe
wrx midpipe
Custom Axleback
Greddy Emanage w/ timing and injector harness and 2 bar map sensor.
Blow through maf

Okay so I had a friend tune it and then i retuned it to work with the FMU. It currently spikes to 12 and tapers to 11psi. I ran a 13.65 @ 99.35mph. The fastest you will get with an ej25 n/a is 15.00....and thats asking for a lot.

Ive beat:
wrx with intake/ turboback
cobalt SS supercharged
b18 civic turbo @ 10lbs (this was when i was at 7psi)

Last night I hung on the bumper of an 2004 wrx with:


OVERALL, not saying this to brag. Just saying this to show you the way to go. I spent 1450 on the turbokit and it was hella worth it.
