Does anybody have a turbo sitting around they can measure? Is it a 3" opening with the bolts centered each 3-1/2" apart? Is it a 2-1/2" opening with the bolts 3-1/2" apart? Any help is appreciated. Thanks.
I don't have a turbo Buick, but I'm looking at using the Buick style turbo on my 68 LT1 Camaro. I was wondering what the dimensions are of the turbine mounting 3 bolt flange(center of bolt to bolt). And what size is the opening(2-1/2" or 3")? Also, are the PTE turbine housings the same 3 bolt...
