The maximum I'm pretty much aimin for somewhere between now and the time I finish all my mods is around 260rwkw's with a lowmount turbo.
At this stage, I'm keepin with the same manifold as I've been told that I can with these new turbo's on the R33.
Plan next week is to get the new turbo put on as well as all the braided lines getting done, new bosch fuel pump, APEXI AVC-R & labour done. Once all that's in place, I'll be runnin about 10-12PSI on just that. Once I put the intercooler on (which will be at this stage a week after all this is done), I'll be boosting her up to 14PSI.
I've been told that I can go up to 16PSI without any harm, but running on a stock standard manifold, I'm not really that game enough.
