okay guys,
I have a 03 impreza with 2.0 N/A engine (( EJ20 with 120Hp )), and I want more power so what should I do??
is it possible to bore the engine block and make it 2500cc (( or +2500cc )), if so then would these fit on my EJ20 crankshaft and rods.

its not worth it, import a usdm SOHC 2.5 block and swap out your old anemic 2.0

 

I know that would be much easier but that will cost me alot of money just for the shipping (( I live in the middle east )) and it really hard to find a 2.5 engine cuz they are very rare in here, so I guess that bore the engine from 2.0 to 2.5 is the easest/cheapest way for more power, but all I need to know is if it's possible on a 2.0 engine!!

 

No, it would be cheaper and easier to just swap in any of the 2.5l engines. You may want to stick to n/a, since your car wasn't origionally equipped with a turbo engine, you will run into alot of problems with wiring and harnesses.
Check out the kits COBB tuning makes for the USDM n/a engines....

(1) the n/a engines have different blocks and heads than the turbo motors, so it is risky to turbo the n/a motors. the turbo engines are more reinforced and have closed deck heads.

(2) get a 2.5 single cam engine or get a new car.

(3) see # 2 above again

 

what impreza has an N/A EJ20??

 

He's in the middle east.

What country are you in? Are you in the military?

 

I'm from U.A.E ( Dubai ) and I don't work in the military

 

guys.... I need to know cuz if possible I will buy the 2.5 pistons and rings and bore my 2.0 engine to make it 2.5
