|
|
From poking around on the internets, I get either 94mm or 77mm center bore (for dowel pins - which one?), 73mm horizontal distance between holes, and 89mm vertical distance. I also need to have the whole assembly flange-to-motor to be 6.4" thick. Can somebody confirm this for me before I get started on the adapter plate?
My design will take my bellhousing, add a plate with a hole in the middle of the same diameter as my bellhousing's input shaft hole (about an inch and a half), and bolt pattern of the torque tube on the outside; then a second plate with the same ID and OD of the ID of the torque tube. I'll then slide all three on a shaft, drill ~6 holes all the way through, and bolt the whole sandwich together; Then drill the four holes in the bellhousing following the pattern on #1 spacer. _________________ 1982 924 Turbo, now Lemon |

The pattern is the same for the 944. Look at the Texas Performance Concepts site for bell housing adapter drawings, etc.
Also there's this:
Taken from here:

Most people doing swaps other than the established ones (Chevy V8, Audi, etc.) sometimes will cut the bellhousing off of a FWD transaxle in order to have the input shaft center which is critical to align everything properly and then mark and drill the bellhousing to match the torque tube nose. I think that is what the VR6 and 1.8T swap guys did.
Hope this helps. _________________ Stefan

Most excellent - this is exactly what I've been looking for. So, 77mm bore, 73.4mm horizontal, 89mm vertical, M12 bolt holes.
I'll post an update as soon as I have something substantial. We have 2 months to do this. _________________ 1982 924 Turbo, now Lemon |
