haha yeah it is a bit like that, but still for the ole rb20et was running 12psi and it did all right, much better than running the standard rb30 carburettor engine i can give you that. I am now running the rb30et with aftermarket inlet for low down torque, camshaft, garrett 35/40 top mount, aftermarket wolf ecu, injectors etc etc runs 240kw with 36" tyres that alot more fun i must admit.
I run a workshop in victoria and do a lot of 4wd conversions and the odd skyline 2litre to 2.6litre conversions.
Doing one at the moment on a GQ Patrol with the 6.2litre L98 V8 out of the new ve commodore should be easily 320kw at the tyres N/A.
