The NA and TT have the same 5 speed transmission model #, same splines on input and output shafts, etc. and the housings are the same except for one small difference. The spot where the starter mounts on the bellhousing on the TT is machined a little differently so that the starter will properly engage the slightly larger diameter flywheel and so that the flywheel teeth won?t scrape the inside of the bellhousing. You can use an NA 5 speed in a TT but you just have to shim the starter out a little with some flat washers and sometimes grind a little out of the inside of the bellhousing so the TT flywheel will fit inside. I used a few washers to space out the starter, other than that...no issues what so ever. Hope this helps.

How about using an n/a flywheel and starter on the tt with the n/a transmission?

The starter really has nothing to do with it. It's just a matter of spacing it if you use the TT flywheel. If you're going to use an NA flywheel, that should eliminate the need to space the starter with washers. I run washers to space mine out with no problem what so ever..but a TT clutch has far better clamping force than an NA clutch, so if you plan to do some heavy modding..just go the same route as I did.
