On either the Y or S bellhousing you can use a double row spigot bearing which will support the input shaft just fine.
Yeah any altezza clutch kit, oem or aftermarket has the bearing in the flywheel. Also, other RWD later model S motors have it in the flywheel as well, like 3/4SFE from cressida's and townace vans. These are 8 bolt as well, although not the correct hole size or PCD for beams 3SGE's, they can be modified to work.
S has them both on the passenger (exhaust) side, Y has them both on the drivers side.
The reason I prefer the altezz clutch kit idea over the double row spigot bearing is that it solves a few of the big 3S RWD headaches all at once. Namely, bearing, flywheel, ring gear and clutch.
Anthony do you have a certain starter motor that you use for the 3y bellhousing? I wouldn't imagine that the original one from the 6 speed fits
ANDY... hav a look a roidchikens thread... good starter solution.... brad is a clever lil boy
the problem we found was getting one to clear the stearing.... with the 3y bell the starter is rotated much further around the bell than the original 6 speed...
brad made a spacer to mount a 22re i think it was... worked purfect.
the beams clutch and flywheel kit is a great solution dont see muc need to fuck about with other stuff.
the back of the engine i went with was
3y bell modified by ant
altezza trd clutch and flywheel
3y clutch fork and clutch slave
22re starter with bradspec mount
even for a muppet like me it all bolted up and worked.
One of the top bell housing to block 12mm bolt holes is out by about 15mm. The other 3 and both dowels are fine, just that one hole. Worth it to get the clutch and starter on the drivers side.
you ever end up doing those modified 20v starters?
