RB20DET was out of R32 skylines.

I would keep it 10 psi till you know how it's tuned. that's about average for a usdm turbo car but japan has much better pump gas so they are probably 14-16 psi

okay.. i know about the rb25 and rb26, but nothing about rb20's. i have a friend with an sr20, and he runs 18 psi, but it's a built motor and tuned for it as well. got pics of the 240?

see if it's stock jdm ecu or stand alone setup.

there is still the possibility they used a chipped 240 ecu
