I just blew up my first 60 in my 93 rx7. car is stock bottom w prc 2.5 5.3's fast 92/92, lt's, cam is not really large 598 605 I believe, 4:10's, 26" slicks, for now only plan to spray 150, have a yank 3400 in it. I was about to order a trans from performabuilt the stage 2 but I started reading on 80's.... at what point is it necessary. I would like to not worry about a trans again... any input is appreciated

 

if you get a built 80, i will almost bet money you wont have one break in your rx 7 again.

 

700rwTQ and higher is a prob I feel. If your car is under 3300 pounds, i'd keep the 60e and get a good build with a warranty

80e is necessary when you get on up there in tq and WEIGHT
