I had a stock SR put down 425whp at 17lbs, I drove it at 20lbs without issues. Then again long term reliability probably would have been an issue.

Re: how much can an sr20 handle
it all depends on your motor red black or notch top... my notch held 20#s but i wouldn't keep it there for every long. with any sr do a good head gasket(cometic) and head studs (apr) you should be fine up to about 350rwhp on a good tune. but don't try to push the stock turbo to anything higher than 15 psi cause you'll over spin your turbo and burn up your seals. believe me i know i've smoked a stock t28 at 17 psi. efficency range for these turbos are about 12-15 #s

What turbo are you talking about? With a T25 you'll be making 265-275 max at 15psi if that. Not to mention your turbo will die very fast at 15 psi. If you upgrade to a T28 and some S15 injectors you can usually make around 300 and I am pretty sure after that to be safe you need to replace some stuff.

Stock block maybe. but at 12 psi it will see around 220 numbers. I dought they last long running 20psi on stock anything. To run 300-400 range you will need to upgrade fuel,z32 maf, atleast 550cc injectors, and ofcourse turbo downpipe.....ect ect. Might as well go ka-t and save $2200.

Oh didn't know that. I guess you can minus the $2200 and add the other stuff. Either way you go it will need a person to tune it for ya. Do it right the first time i say.
