Rb26 R32gtr Stock Motor

[locoloc]

car: 1993 r32gtr.

I am in the process of getting a pair of -7's to replace my stock turbos'

My engine is stock with no modifications apart from exhaust and ecu.

Does anyone know what a safe boost setting is before i start straining out the engine.

My intentions of changing the turbos was so the stock turbos dont suddenly fail and damage my engine

And by replacing the turbos I dont want to boost them that much that i end up blowing the motor.

Any suggestions/experiences greatly appreciated.

cheers

15yr old motor - unknown condition...

16psi which will give you around 280rwkw. Should hold and last nicely.

You can obviously run more, pust more etc but at the end of the day if you cant afford a rebuild then dont dance with the devil

was hoping i could run it at 16psi too

280 is a good figure as you should be able to get away with stock injectors and MAFs. Many guys do the fuel pump as insurance since they're getting long in the tooth. You'll probably need a better clutch depending on what you have now.

Make sure you replace the dumps with something better and the o2 sensors while you're in there doing the turbos. Stock 32 dumps are crap, and in theory the o2 sensors are scheduled for replacement at 40,000kms. The originals may still be working but probably wont for much longer.

Try 280 first and see how you like it. You cant sensibly use that much on the street anyhow.
