The turbo is a s400 based turbo. Clipped to fit compressor wheel, so no its not a true 66mm wheel. My no genius when it comes to turbos, especially the exhaust side of things, so all i can tell you is what they wrote down on my paperwork when i bought it...Exhaust wheel 3.286 -2.925 or 74mm, whatever all that means, Im guessin 74mm, but seems a little small, maybe not. If someone would like to jump in and help me out, id appreciate it as to what that truely means.
On another note...I just bought a 07 commonrail megacab that has 90hp nozzles on it. Il be getting efi live in a few months, and plan to put an aftermarket turbo on it. So what im basically askin if anybody thinks the turbo i have listed would be a good one to use or not. I do pull my pulling truck with it, so i want it to work well for that also. Thanks for any help. If anybody is interested in the turbo, let me know because it is still for sale.
