I recently test fit a downpipe I had fabricated by Abe at Artech. The turbo is a Garrett T3 60 trim from an old Ford Mustang SVO. I did not send the turbo to Abe because he said he had a T3 turbine housing he could use and I did not think that the 5 bolt outlet of my turbo would be any different from any other T3. The problem is, 2 of the 5 mounting holes for the outlet do not match the downpipe, as seen in the pictures. My question: Is it possible that the outlet on these old Ford turbos is different from that of a normal T3? I was under the impression that the 5 bolt "ford style" flange was the only 5 bolt outlet for T3 turbos.

Here is a 5 bolt gasket I found on ATP's website:

I don't have direct experience with a ford style flange, but I had a normal t3 flange that didn't work on my turbine housing and it turned out that the larger Mercedes t3 flange fit.

 

Do you happen to have a link? That might just be what I need. I can't seem to find any vendors that provide measurements for these things.

It doesn't look like they post the dimensions for it either.
