I have been considering this modification to my 71 TR6. I have not purchased
or installed one (yet) so I have no actual experience with it but I can
answer some of your questions.
1. Contact: http://www.conversioncomp.co.nz/
2. Looks like mostly a bolt in job however another lister named Chad Jester
said:

3. Good question. I don't know. See number ten.
4. When I was looking at it, the price was around $1300 to $1500. Depends on
the conversion rate and which tranny you buy.
5. It's been rumored that XKs Unlimited is the US distributer. Expect to pay
more there.
6. Don't know.
7. Literature I received from Conversion Components says "Supra Gearboxes
are ex-Japan, cleaned and checked over before leaving the factory."
8. Gearbox internals and clutch parts should be readily available in the US.
This is after all a Toyota transmission. The bell housing and possibly the
gear lever remote are made by Conversion Components.
9. Don't know. I would expect the Toyota gearbox to be quite reliable.
10. There are 4 gear ratios available. Here is how they compare to a
standard TR6 transmission (specs from Bentley):
1st 2nd 3rd 4th
5th
Stock TR6 non-OD 3.14 2.01 1.33 1 -
wide ratio (std) 3.56 2.05 1.38 1 0.85
close ratio 3.28 1.89 1.27 1 0.86
close ratio high 5th 3.27 1.96 1.31 1 0.775
extra wide (rare) 3.95 2.14 1.38 1 0.85
My choice would be either of the close ratio gearboxes. I suspect first
gear in the wide ratio boxes would be to low to be very useful. The first
four gears in the close ratio, high 5th gearbox are very close to the stock
TR6 ratios.
11. $1650 sounds a little high. Back in June, Chad Jester said this:

I don't know if he still has it or not.
Hope this helps. Let us know what you decide to do. Especially if you
install one of these!
