G'day Paul,

Had a REAL good talk to my Bell housing mate Jeff this afternoon.  No
worries!  We can make a new set of patterns from the existing ones pretty
easily.  Can do it for either the later model '86 onwards flywheel/starter
motor combination, or the earlier model.  I think there would be more call
for the later model. I've taken some pix,  but won't be able to post them
for a couple of days.

It is possible to incorporate any provision for any mounting arrangements
that you like.  The mounting pads can be made thicker,  strengthening ribs
can be added to the bell housing as required,  and the thickness of the
housing can be varied. I could mimic your plate mounting idea and
integrally cast them with the bell housing itself or they can be cast
separately as custom mounting brackets etc etc.  Give me some ideas of what
you think Paul.  I'll be going out to see Jeff again later this week with
my Subaru sketches once I have my ideas formed up.

Jeff usually uses 6061 for his auto bell housings,  and they are obviously
sand castings.  A range of casting alloys is available,  and can be
specified in the case of a batch run.  It's a bit hard to do this though
when doing one-offs.

Preliminary costings are around $475 ~ $575 AUD ($250 ~ $300 USD ) for
individual units,  depending on the bolt pattern drillings on the PSRU
mounting face and complexity of mounting provisions that need to be
incorporated in the patterns etc.  This price could be brought down
considerably if 5 or more units were ordered at a time,  as a lot of the
cost is in the set-up time.

Paul,
I am glad this is working out to some degree----I am glad it is going
somewhere!
This sounds real promising.........I like the idea of flexibility to some
point, esp since I have heard that Tracy may be considering making a 6
pinion constant speed hub in the not to distant future. $300 usd sounds
good too.

I think we should stick to the auto tx flexplate and Tracy damper as we have
a history with these. I don't want to go through R&D on a new damper and
flywheel.

Agreed!!!! Loen could let that go unless others want the option........
Good to go with the cast in 29" c to c motor mounts wide enough to
accommodate a turbo a la Smale-your solution for a side by side.
  I also think there are enough of us having late model "Cosmo" type
automatic bell housing starter situations on the engine rear housing and
would like to retain that starter location option-spark plug side
low.  (all orig 20B Cosmo, all orig 13B Cosmo,  93+ 13Brew auto versions).
A glance at a 93+ auto bellhousing would show the entire side engine
layout, and would accommodate Tracy's/Mazda's auto flywheel that Tracy uses
as well as the automatic starter (Tracy doesn't know this, but the 93+ auto
flywheels are identical to the earlier 13B 89+ auto flywheels).
Perhaps Tracy can also offer to "up" the order quantities and get prices down?
Would Leon take "special orders" as well?
Perhaps more pictures to Leon of Smale's version we saw previously would
help him?

Opps I sent the wrong picture with this the last time.
