I got this turbo with an engine swap I did a few years ago, and I honestly don't know much about it. I believe it is a t3/t4 style turbo, with a t4 flange, and is water cooled. I ran it on my 1jz for almost 2 years before I swapped to something else. Unfortunately there are no casting numbers or anything to cross reference, and I haven't bothered measuring anything. Minimal shaft play, didn't leak any oil while I was using it. It worked great on my engine, would suit anything from a 2.5 to 4 litre engine, depending on what you want to get out of it. It is gathering dust in the garage and I want it gone. Call or text for fastest response. Thanks
