race preping a r154

[pandrade]

hey guys I know the r154 is a very robust and well designed tranny but it has its flaws like any street car can. mine is a daily driven car but I auto cross 2x a month and I have project money tucked away because in 3 years I plan on racing mine in pikes peak international hill climb. the first thing im going for is a 21 point roll cage and new garrett turbo, so after all of this I figured the tranny will be taking abuse so lets prevent problems before they surface.

the supra store sells this rebuild kit which looks real nice

on top of this im wanting to buy a short through shifter from drift motion

and of coarse I would use a proper clutch that would handle 600 lbs of torque( im building this as a torque motor not a hp motor. im trying for 500 lbs of torque but plan on 600 to be safe)

the diff still grabs hard so im happy whith it, all else I can think is 1peice aluminum drive shaft(or at very least replace all the u joonts in my factory one)red line synthetics in tranny and diff, have the gear sets shot peened.

if any one else has any ideas how to make the tranny better I would like to hear it
