Yeah, i agree with joel, when it runs rich the extra fuel can wash the oil off the bores, not good at all for running an engine in. I would put the stock pump, injectors and ECU back in just to run it in, then upgrade. Hate to see a new motor fkd.
DET, Plain bearing VG30/RB20 HYbrid. Thats 15-16psi, not 10psi, the same turbo on RB20 didnt make 15psi till after 4000rpm. RB20 roller turbo would be much sooner than 2800.
Anyone know if R32 RB20 turbo valve springs will fit the R32 N/A Rb25 head, and are the turbo Rb20 springs Stronger (More seat pressure) than the n/a ones?
Any help appreciated.
