He guys I was just wondering if there was a difference between a t3 5 bolt flange outlet as opposed to a t3/t4? Well heres the problem i had a t3/t4 turbo now going to a super 60 t3. While installing i notice the five bolt flange on the downpipe didn't match to the five bolt on the new turbo. Is it just me or are the flanges different? Thanks

 

There are a few different types that different manufacturers have used. Post a picture of the housings or maybe the flanges and someone might know exactly which one it is.

 

soem flanges have to be a bit bigger, like my flange it was a t3 5bolt from a mecredes... really hard to find.... a lot of people just notch the holes on the standard 5 bolt flange and throw it on like that. If that is what your problem is....

 

It completely depends on which exhaust housing is used. A t3/t4 is just a t3 size exhaust housing mated to a bigger compressor wheel and compressor housing.
