i-Club - The Ultimate Subaru Resource

Engine/Power - EJ20T (pre-2006 WRX and JDM) There is replacement for displacement, it is forced induction - OEM 2.0 liter turbo engines in the USDM WRX. 90-94 Legacy Turbo EJ22 turbo engines can also be discussed here.

Strength of internals?

Strength of internals?
Anyone have a rough guess as to what the internals (pistons, rods, crank) on a 2.0L WRX engine can handle? What can I crank the boost up to?

I'd just like to see how far I can take it before I start blowing stuff up.

Thanks,
-Travis

Are you planning to only increase boost with a MBC?

WIth aftermarket turbos 18-20 psi is probably the most boost you can run. otherwise 14-15 w/ the stock turbo to be safe
