Hi all,

New to the subaru seen having just bought a shell, want to start getting bits for the rest of the car together now.
Having read the enginetuner article in total impreza a 2.1ltr sounds a good engine, more torque, faster spooling turbo, anymore benefits??
Is it worth stroking the 2.0ltr or just buying a 2.2ltr??
I know the 2.5 crank is used, are the standard rods and pistons used or would the comp ratio be wrong??

Any info advise be appriciated, my knowledge is poor on these engine

I intend building the engine up using a closed deck block & forged internals, for around 400-450bhp

 

i think you require longer rods and stronger pistons. Best to contact Alan Jeffery on here and i'm sure he would be more than happy to assist

 

I think Alans article will have covered most of the benefits, another possible plus is £ for £ the stroker is not to different to a forged 2.0 in price but has many benefits. As above contact Alan and he will I'm sure be most helpful, to answer your quick question the STD rods and pistons are not used.

 

I think you will have trouble finding a 2.2,and when you do it wont be cheap. They are about but most people build them, be hard to find a 2.2 bare block.

 

im in contact with alan from engine tuner atm about his 2.1 he uses New nitrided 2.5 crank,Wiseco pistons, K1 H beam rods, Cosworth engine bearings
his prices are very good and a very helpful chap

 

Std. New-Age STI motor is good for 450 bhp, the 2.1 is a sensible price up-grade IMHO.

what power will the ej25 crank handle before having to be replaced with a uprated item??

 

500 + it's the 2.5 rods and pistons that can't, IMHO.

how much does a 2.5 engine cost? would u need whole engine or short block?is it straght swap for classic and what about wiring loom ? 21 questions
