I purchased a TT trans 1994 spec and has about 60k on the trans. I am swapping the transmission into my z31. I know there is a forum already explaining the process but I want to retain my bellhousing from the Z32 TT. I already have a z32/z31 hybrid flywheel from AASCO Motorsports. Iâm using the 240mm sized flywheel with the ring gear from a TT flywheel which has a 250mm originally. Can anyone please tell me if I will have an issue bolting on the z32 TT starter? will I have to shave any part of the bellhousing? The reason why Iâm trying to retain the TT bellhousing is because a pathfinder bellhousing or a z31 30a bellhousing was harder to find. Any insight on the situation will be greatly appreciated.

The diameter is not an issue. The TT flywheel is thicker and that's why people clearance. Since you already have a TT trans. It won't be an issue. The diameter spec refers to the clutch surface area and not the ring gear.

Oh ok. So the TT starter should work with my combination as well. Would u happen to know if any type of shimming of the transmission or hammering of the tunnel would be necessary?

Did you ever get this figured out?

I don't think the TT starter fits without massaging the chassis.

Iâve been away for a minute but when I get back home later in Late July and August I will post pics of the swap. Iâll be as detailed as possible. As long as the starter will mount up fine I should be ok but if it requires âmassagingâ thatâs going to be something I need to address.

I'm using a z32 NA transmission, bellhousing, and starter. I had to slightly massage the trans tunnel to get the starter to bolt in. Not much though. I didn't shim the starter and am using a maxima flywheel. Every 20th start or so it misses the flywheel and makes an awful noise.

I have Z32 conversion flywheel new in box.
