In process of building civic 4 door powered by b20 vtec with gt35 turbo head is super tech valve train w/itr cams in a gsr head

I am little low on cash now to build the block so for the mean time I wanted to know a aggressive boost poundage I can run on this setup without blowing the motor first time out

 

You could blow it up at 1 psi, or 30psi. What is more important is power level and the tune. You don't mention any work being done to the block. If you have forged pistons/rods then you could make much more power than if you have a stock bottom end.

 

Psi of boost is irrelevant.


10 psi on a t25 and 10 psi on a 40R are two very different amounts of airflow.

its all in the tune. many stock (unopened) engines over 400 hp and higher with a good tune and attention to detail.

 

<<<<28psi@590whp

but as stated the block is only as good as the tuner really man

 

OP has some reading to do....

 

Thanks for reply

Lots of great info

I have gt35r turbo stock block no pistons no rods b20b4

 

Like mentioned multiple times, boost means absolutely freaking nothing. Nothing at all, so you can drop any idea of using it as a benchmark in your build.

You need a power goal. My completely stock F22B1 at 220k handles 245whp just dandy. Its all about how you go about doing it, and ultimately your tuner.
