I am looking to buy an si here soon and i wanna turbo it . I am just wondering if anyone has one b/c i would like to run between 9 to 12 psi and i wanna know what type of engine mods i should do to run that much and if anyone has any pics that would be great

 

My friend blew his at 9psi . He now has JE pistons and eagle rods and is turning the boost to 10psi.

 

one of my buddies has a 95 gsr and he was running 8 and he blew his to and he is redoing everything in it now dont know what all he is doing though

 

If you plan on running 9-12 psi, build your motor so it can handle it. Otherwise, you're gonna run into problems like the guys mentioned above.

 

my homie with an ls..ran a 12.9....at 8 pounds of boost.....and 212 horsepower to the wheels......stock motor....

 

From everything I have read, it seems that a stock b series should live for a long time with 9 lbs of boost IF it is properly tuned. If I ever decide to stop being responsobile (it is a curse) and go turbo, I am going to do the math, and put together a low cost, efficient kit, and spend the rest on Apexi PowerFC or similar with some professional instruction on fuel curve tuning.

Yea, I know it is a long sentence.

 

Unless your getting a 3 bar map sensor you can't run more than 11 PSI of boost anyway. But with proper tuning, you can run between 8 and 10 PSI of boost on a stock block. Above that, you should consider upgrading the bottom end.
