I thought this turbo was a T3, so I bought a used manifold and downpipe from a Drag kit to build my cheap turbo kit. Compressor side is stamped with .42 and exhaust housing is stamped with .49. The exhaust manifold doesn't match up to the exhaust housing on the turbo. The bolt holes on the turbo are 3 inches appart and the manifold is 3.5 inches appart. Also the downpipe bolt holes don't line up. The pattern is almost the same, but the are different. If this isn't a T3, then what is it? I thought all the T3 flanges were the same.

 

what brand is it?

that turbine outlet looks just like something from a WRX...

 

You can kinda see in the last picture on the bottom, it has Garrett stamped on it.

 

i have the same exact turbo.. people here told me it was a t3.. look at my sig..

 

I would have to measure one again, but that definately looks like a t25 flange, and it is also consistant with the .49 a/r of a t25 family turbine housing. The compressor looks a lot like a t3 however. Hope this helps

 

looks just like the turbo on my 280zx.

 

I'm wondering if a T3 exhaust housing would bolt onto this turbo. It looks like it should. If I could do that, then everything would line up and work.

 

Nope. Not a t25 flange. The t25 flange is more square than that one.

T25 dimensions center to center of bolt holes are: 2.265"x2.930"

Yours isn't even close.
