BTW if any of you had to pick a turbo to throw on the SR20DET. Which would you choose??

Im thinking T3/T04 making 450HP

***Actually a GT3037 is about the best turbo suited for the SR20DET it is a bit expensive. Realistically though a T3/T04E will get you to those power levels easily.

For example a T3/T04E with 0.82 A/R turbine housing and Stage 3 turbine wheel will put you at about 410 whp at 22 psi. To get to 450 whp you would need to run about 25 psi which turbo is certainly capable of.

If you want over 500 whp then upgrade the turbine wheel to a Stage 5 T350 turbine wheel 0.60 A/R compressor housing with a 60 trim compressor wheel.
