I have two bellhousings welded together so I could use the R151F. Unfortunatly toyota put a reverse style clutch into the R154. Same tranny as the R151F, but the R154 had a longer input shaft, so the bellhousing was longer. And you can't swap out the input shaft because the gear welded onto the input shafts are different.

Ah. Gotcha. I've *heard* that you can put the 154 shaft into the R151, but you lose that kick as first gear. Is this correct?

But, if you don't plan on pushing over 300hp, you can run a W series tranny. I would not use the G series, the internals are weaker. To make the W or G series work, all you need is the bellhousing from any 83-92 N/A 5 speed supra, then of course you will need the clutch assembly and slave cylinder.

Thats what I wanted to know. I'd run a W56, and will be looking to keep the power down to a reasonable level (gotta love a motor where you have to worry about that, not the other way around)...
