I would like to know the measurements of the T4 exhaust flange crossing the bolt holes. I just want to see if the turbo I have will fit the T4 flange. Will the 3rd gen exhaust manifold fit the 87TII block? It's just I sell OBX parts and I was wondering if with a little cutting or so if it would fit. Thanks for any responses.

 

I have a turbo off of another vehicle and I just want to know if the turbo I have has a T4 flange.

 

2.75x3.25

A 3rd gen exhaust manifold will most likely not fit a 2nd gen b/c the LIM on a FD is much closer to the block than on the FC and usually so are the turbo's.
