Hey, I am fixing to get a turbo kit for my si.I was wondering what kind of boost I can run safely with out strengthened internals.I was planning on running 6-10psi.Will getting a intercooler witht he turbo help me get more power out of the turbo kit.

 

Forced Induction forum.

 

spade is right, you will get more responses there......as for your question, you can safely run 6-7 psi daily and 9-10 at the track, and by safe i mean properly tuned....good luck

Stock well tuned you should be okay at 10psi max. Now im not sure what SI do you mean, there are gazillions of Si, so im assuming is the 99 to 00 DOHC VTEC coupe right ? If so read on.

Personally, if are pursuing into going faster by upgrading your internals at a later time, ditch away the HKS and go with a Drag turbo kit. They use the T3/T04 turbo that has much more potential as you upgrade your bottom end. The kit is complete with everything you need to bolt and go at 10 psi your stock injectors will be fine, if not you can always upgrade to a safer 310's and changing your fuel pump is very beneficial.

Im not dissing HKS, but I think they made a joke of themselves using that small of a turbo for that car, but again they are smog legal, im sure they took consideration since it had to be smog legal to please the californians

 

si in most countries are ex's (i'm guessing he's from bangkok)...t25 on a ex is pretty decent althought u'd prolly want to go with a t28 or something with more top end... those t25's die off too quickly
