Nick-You are 100% correct , they don't have that issue in JP because 98% of them are running twin or triple discs.
Ali- If you do the 350Z get a twin disc clutch , if not do waste your time machining your bellhousing Because you wear out your input shaft bearing because the dowell pins will not be used to line everything up.
I know a guy that's making 830whp on 1jz with S366 with that trans and after talking to him i decided not to mess with that setup.

Reason: Not break...
so the twin disc will make up for the milling of the bellhousing. very interesting.
I just found out they make a twin disc for the w58 that will hold same power as I have right now, but its 1800, that almost like a r154 swap.
I wonder though how much abuse a twin disc w58 can take over a regular setup. probably the torque will still break the trans while the clutch holds strong.. lol

Well here's the thing. You have to machine 1/2 off the bell housing. When you do that you loose the dowel pin holes and his adapter doesn't have any anyways. So you're left with the bell housing bolts to align the input shaft with the crank center line and there is just to much error. I've wore out two input bearings in a short amount of time just because misalignment.
