On a completely stock K20Z1 (06 RSX-S).. what can I expect this thing to be full boost at? I'm only planning on running like 6-8psi (FOR NOW). The future will forsee a forged bottom end, but not now.

Garrett 60-1 Turbo

The turbo specs are:
cold side a/r- .70
hot side a/r- .63

this is a 360 thrust bearing turbo.

Need to really know what turbine wheel you are using?? You really should get one with something bigger than a stage 3 turbine wheel if you plan on pushing the turbo in the future. There is almost no difference in lag between the stage 3 and a stage 5 turbine wheel.

 

i have the stage 3 wheel on my 2 liter B series vtec. it makes 6-8 psi around 3500 rpms, 12-13 psi at like 4200 and ive got 17 psi at a little over 4500. this is in like 3rd and 4th gear
