ok i have a rebuilt streetported motor, HD ACT clutch and SR motorsports 11lb flywheel. i went from a 3.90 open diff to a 4.10 lsd. obviously i converted it to MT from AT. when i did this conversion i used a used NA tranny to save money. well im already on my second transmission and i feel that my torque is just too much for the used NA tranny. what do you suggest i do to get a more durable transmission?

understand that i spent $850 on the flywheel and clutch, i dont want to just get rid of it cuz i wont make anything back on it. i know i could do a t2 drivetrain, but what are my other options. are there any stronger transmissions i could look into that i could keep my flywheel and clutch? would i be able to rebuild my used NA tranny and make it stronger?

the n/a tranny is actually one of the weakist trannys made and are peices of ****.
Sorry but its true,I went through 4 before changing over to a tII-Have had it for 2 years and not a problem yet,I am still on the same A.C.T clutch with it also.

 

if i do go with the TII tranny can i still keep the NA 4.10 lsd? i know that if you go with the TII rearend im pretty sure you also have to do the half shafts and everything and those are hard to come by. i know i could get a custom driveshaft made, but how much do those cost?

also how much would a HD ACT clutch and 11lb SR Motorsports NA flywheel go for used? anyone want one? lol

Mazdatrix has an aluminum driveshaft for about $400 and new half shafts are around $400 there as well. I am looking at going the TII route for my 'vert after experiencing similar pains (ie-sunk money costs). But at the end of the day, nothing is too good for my RoXie-7.
