Advice On What Turbo I Have Please?

[Bennieb88]

Gday guys. I have recently purchased a r32 gtst with a few things done to it. The person i bought it from was a bit unsure on the details of the mods as he bought it like it was.

Basic run down from what i can see is that it has a fmic and turbo back exhaust with a split dump. It has a dyno sheet for 211rwkw at 16psi. The car has no boost controller, the wastegate actuator is running straight from the intercooler piping.

My conceren is that i dont know what turbo is on the car. It has nissan on the compressor housing but it doenst have any numbers printed on it (like 16v or such) and there is also no flange for the intercooling pipe. It starts to spool up at around 3500 rpm and makes full boost by about 5500 rpm.

Im sorry but i don't have any pics to post up here just yet. It may be a bit difficult but does anyone have any ideas as to what turbo this may be?

Thanks guys

With no pictures or serial numbers all I can say is it maybe is a high flowed turbo.

[Bennieb88]

Im really sorry about the pic. Its the only one i have atm as the car is at the mechanics atm.

Apparently the vehicle has been running like this for at least the last three years. If this was the stock rb20 turbo would it be able to last three years on 16psi with out going pop?

Cheers

Would have to agree with the above. Nissan stamp but starts spool at 3.5, some sort of high flow core. Some turbo builders put a tag on their cores. See if u can spot one. A boost controller will def help bring the boost on earlier and harder.

[admS15]

It is possible a stock turbo could last 3 years @16psi if it hasn't been getting thrashed constantly

[Bennieb88]

Cool thanks for the replies guys. When i get the car back ill investigate the core. My main concern is the turbo letting go thats all. But hey if it lets go it lets go i guess haha.

[Hadouken]

That housing looks to shiny.

Probs hi flow.

[Bennieb88]

And seeing 16psi with the wastegate actuator running straight off the intercooler piping, would that mean the actuator has been upgraded too?

[GTSBoy]

Has to. You'd only get 10 -12 psi otherwise.

[Bennieb88]

Yeah thats what i thought, just wanting to make sure as this is my first rb motor. Thanks for all the help and advice and not grilling my due to the lack of info supplied. I appreciate it guys.

Cheers

Pretty sure u wouldn't get 210rwkw with a stock rb20 turbz either.

[Bennieb88]

Yeah again from what i have been reading that seems true. I only paid 4 grand for the car so with how hard it pulls im pretty happy.

[sneakey pete]

VG30 turbo or something like that perhaps?

[Bennieb88]

That may explain the lag, the only thing that has me confused is the fact that there is no flange for the intercooler piping and there is no numbers stamped on the compressor housing.

Oh the joys of buying someone elses project haha

[GTSBoy]

The compressor housing is definitely RB30ET. If the rest of the turbo was also originally a VL unit, then it's quite possibly no surprise that it doesn't perform really well.

What's really interesting is that while its behaviour sounds like a highflow job, the compressor inlet doesn't look like it's been machined out at all. Whatever the case, it probably doesn't belong on an RB.

[Bennieb88]

To be honest it doesnt bother me too much that it is a bit laggy. Its my daily so driving around town not seeing boost is good for the fuel economy. I am mainly concerned about the exhaust wheel letting go if its a ceramic wheel thats all.

[GTSBoy]

It's not going to be ceramic. No highflow is and the VL turbo certainly wasn't.

[Bennieb88]

Sorry to dig up my old thread, but upon further investigation i have also noticed that the wastegate is actually part of the dump pipe, and its a 5 bolt dump. Does this sound like it is off of an rb30?

[GTSBoy]

Have you googled pictures of the VL turbo?

[tridentt150v]

The wastegate and bolt setup sounds like the turbo I had when I bought my Gts25t. I got it hiflowed and it made 245rwkw but was a teeny bit lightswitch - almost deadly on a wet day. I ended up going for a turbo with a better spread of power.
