No offense Dick, but I have to disagree.
The weakest links I see in a stock car (after thrust-washers, clutch and
tranny) are in the rear end/ rear axle bearing components. That is based
on failures on NON- modified cars. Although there are a few folks using
big motors in TR6 cars with the stock back portions, I feel it is
ill-advised. A lot of the present day racers ( bless you all) changed
these components due to sometimes spectacular failure........ imagine
loosing a back wheel when the axle shears in the outer hub! One other
note:Kastner and company used MODIFIED axles and Volvo halfshafts on
their successful racers.
One of the other posters mentioned the PI cars having 150 HP. That is
true. It is also true that 150 HP coming thru a 3:45 rear transmits less
stress on the system than 150 HP thru a 3:71 rear. All PI cars came with
a 3:45 rear, and most US cars come with a 3.71. I would also respond by
asking how much is too much power? :^) I personally am after 300 HP,
and that is absolutely out of the question with the stock engine. I am
not rich, and seeking 160 stretches the pocketbook.
Ryan may be OK with Corvair axles and an early diff with a hardened ring
and pinion. In addition, I certainly would beef up the diff mounts on
the frame. At a minimum I would talk to the folks at
http://www.pond.com/~britcars/ to see what their experience recommends.
Good Luck however you choose to go Ryan

PS
One of the things to check on that combo Ryan, is where the shifter
ends up in the passenger compartment. Take a tape measure to the JY and
measure from the back of the motor to the center of the shifter on the
Supra, and compare to the TR to get a general idea. Ergonomics really
affect the end result in any conversion. That's why there aren't many
daily driver Cobra's ;^0
