How High?

[koleka]

so how high can you boost your stock turbo in an R32 GTs-t, before you have to start replacing the stock turbo and fuel pump and what ever else?

ta.

14/15psi until the zorst wheel comes off...

depending on condition tho it might explode sooner.. Its all luck of the draw...

I wouldn't bother doing it in a totally 'stock skyline' as the gains will be minimal ..wait off until you have replaced the exhaust system, and fitted an intercooler.

Mine started to go lean after 12.5psi, it made 152rwkw.

A new fuel pump was required for 14psi as the old one was a little tired. As expected, the car was 10-11yrs old at the time.

I ran the turbo at 15psi then 16psi towards the end. It was fine. Providing the tuning is ok and egt's are kept as low as possible (no lean, no detonation, no super rich, no track or extended periods of WOT)

i was told that a safe boost would be bout 11 to 12 psi, but once you put an exhaust and pod filter the boost will rise to that amount from stock which is 9-10 which i was told by neil_se

The r32 wastegate actuator is different to other models so stock boost is 9-10psi, on an r33 and s13 its 7-8psi, so 11-12psi with your mods is pretty normal.

hope this helps.

"no super rich" <---- What does super rich do to EGT's?

Run it super rich (highly unlikely) and egt's will go high.

I shouldnt hav included it really as we won't see rich conditions as such.

No idea what afr that would be at as its theory.

Google EGT's... Quite interesting.
