safe boost for stock turbos on R32 GTR?

[abcd.24]

Hey guys I am planning to run more boost on my R32 GTR. What do you think my stock turbos can handle safely?

Thanks.

It's not so much as what the turbo's can handle as what can your injectors/ecu maps handle...

You can over run the fuel system before the turbo's.

No more than 12psi on stock fuel system, and I can't stress that enough.

Stock turbo's have been known to handle 15-16 sustained psi and lasted quite a long time but on the other hand many have had issues arise at 13-14....They are old and tired.:zzz:

Ceramic exhaust wheels... :(

i would leave the boost alone... keep it at stock psi.

those turbos cant handle much boost

the exhaust wheel tends to fall apart.

start saving up for an engine rebuild as the oil pumps tends to fail as well

Just upgrade to an N1 oil pump.

How many km's are on it? Is it tuned?

or you can do that, but the job will cost $1000+ because the motor would have to come out.


GTR Turbos are known to go, no matter if its high or low km's

Ya true enough. Even at ~100,000km, it's advisable to have the engine rebuilt with new turbos. Being a JDM car, it probably says 40,000 but should read 140,000 :rofl:....Just an excuse to upgrade parts I suppose :devil:
