Can someone identify this turbo for me? I was on the truck when I bought it, and have had no problems. I was told it was a Garrett GT35R by the man that installed it, and he is an honest person. I am not doubting him, but all Garrett turbos I have seen have some marking on them indicating they are Garrett's. Inlet is approx. 2.5". There are no marking on the turbo, other than the A/R ratio. It is internally wastegated. It had to be clearanced to fit with the A/C (see pics). Any insight would be helpful.

Thanks.

Might want to get some pictures of the whole turbo and anything on the front cover.

Re: heip identify turbo

A Ball bearing GT35R will have both coolant and oil lines. Most GT35's that I've seen have a 3" or even a 4" inlet'd surge cover on them, but not mandatory. The compressor wheel is staggered like it should be, but that's VERY common for just about any turbo these days, our 17C is one of the exceptions. Is the compressor housing held on to the center section with bolts? GT30 and GT35's aren't, there's a large snap ring on the ball bearing center sections, from what I've seen.

Hard to say what it is without removal or getting pictures of a ID plate or something.

Just checked. Approx 3" OD inlet, that tapers down to the compressor turbine. No bolts holding the compressor housing to the center section. Does have oil and coolant line. Just had the thing out, should have taken more pics. Thanks for your help.

It likely is a GT series turbo. I've had both a GT30R and a GT35R (on a different car) and they all sound like what you have.

I think a GT35R is an awesome turbo for the 4.3!
