I plan on boosting my JDM gsr B18C and I plan on installing eagle rods and wiseco pistons 9:1 compression with ARP headstuds, new OEM headgasket and stock sleeves. What is the max whp this can handle? I know a bone stock gsr safe zone is around 300-350 whp depending on the tune. How much more could forged intenals and ARP headstuds take it to?

Thanks

 

~500whp is said to be the limit of stock sleeves.

What fuel is it being tuned on? Why lower the compression to 9:1 it's not necessary.

 

oh alright and its being tuned on pump gas, I thought it would be safer to run higher psi with lowered compression? I just think 10:1 compression is kinda high. and thanks

 

Depends on the turbo

 

Heh.. No 10.0:1 is perfectly fine. Your thinking (1970s-1990s) methodology is very outdated.
