i was wondering what the compression ratio on a stock wrx ej20g.. ive tried searching and i couldnt find my answer.. reason of asking is.. im tryin to determine my comp. ratio since im using a jdm v7 sti 2.0 block with usdm wiseco pistons.. any kind of info will be greatly appriciated. thanks!

8.5:1 from memory.

there are MANY flavors of G some are 8 some are 8.5

wrx were mainly 8:1, while sti 20Gs were mainly 8.5:1

I am running a ver8 block with the EJ20G heads - I figure I am around 8.2x:1

sweeettt!!! good info.. so around 8:1?? i have a gf8 wrx motor.. non sti, non RA. its not closed deck either.. hehe.. i need to figure out since im running a v7 block with wiseco usdm 2.0 wrx pistons.
