Text On Factory Turbo? ('93 R33 Gtst)

[brother_david]

My '93 R33 GTST type M arrived to Sweden a few weeks ago, the boost gauge is broken, but i finished installing a HKS EVC III today, so that way i could see the boost anyway.

Some things upgraded on the car is 5Zigen exhaust-system, HKS induction kit, apexi boost-gauge (the broken one )

The problem is that it hit 1.04 bar (about 15 psi) and there i backed of, not wanting to blow the turbo, or even worse (this was when the EVC was off, just showing boost).

It doesnt look like the wastegate has been tempered with, i havent found any other boost-controller, nore have i found any leaks on any vacuum-hose, so simply i dont know how the boost is raised!

So i was thinking that the turbo might have been changed to another one (along with the WG), but since i dont know how to recognize the factory turbo, i dont know if mine is or not, altough i have seen a 'NISSAN'-text on it.

r33 turbo's usually have a few numbers on it like 42V5 or similar.

without taking it off, you can't really tell if it has been rebuilt/hi flowed either.

if it is getting that much boost and more unless you back off, I'd guess that the wastegate is not seeing any air supply and just not opening at all.

I'd check the wastegate hose for a leak or blokage.
