What Turbo Did I Buy?

[klutched]

So I picked up this turbo for my 33 a few weeks ago now and was doing some research on it and found that it's not a proper gt3076? Its a "3076" .82 rear but has a .70 a/r comp housing.

CHRA P/N is 700177-5011

Can anyone tell me a bit about it? Is it worth keeping or should I sell it and buy a proper gt/gtx3076r?

Why don't you think it's a GT3076?

It is correctly labelled a GT3076.

That part number indicates it is running a 76mm OD compressor. But it's an old school T04S spec compressor, evidence is in the 7 blade impeller. Also note the 0.7 A/R housing fitted to it.

The one usually referred to as GT3076 on this forum runs a 6 bladed compressor and a 0.6 A/R housing with funky surge slots and provision for an internal bellmouth as fitted to the HKS branded units made by Garrett/Honeywell. It is also (correctly) labelled as a GT3037.

It's all in the part numbers. Google the number off your unit, and also search this forum. It's been discussed before.
