Depends on the driver. If its me driving, not very much.



I broke an FB tranny in a month with a stock port engine. With a ported engine, I broke a S5 n/a trany, which is the strongest of the n/a trannies, in a month.



Some people have kept n/a trannies alive with a turbo 6 port. You have to drive very nicely though, and youre still flirting with disaster.

thanks for the reply. my tranny is an S5 tranny so i guess its the thoughest N/A tranny. i hope it can withstand the occasional auto-x. i don't really get on it much around town cuz my lisense has been flagged by a state trooper



anyways, i hope that i can make the tranny last long enough for me to find a TII drive train.

If you dont have some serious mods oen, dont worry about the n/a driveline. Unless you have a heavily ported engine along with the bolt-ons, and have a knack for breaking things, youll be fine.

our race car (its/ps1) goes thru trannies. due to the rules its stock port/ stock intake manifolds.



i pulled an old one apart, all the synchros were shot, 3rd was broken. chipped gear tooth on the input shaft and the 3/4 clutch hub is toast. the one in the car i think is gonna be the same



we also dont make any kind of standing start....

You must drive like I do.

Ryu

as for mods, i'll be running full turbo back exhaust with an intake so nothing to extreme.

I’ve put 420,000 miles on my original S5 NA transmission. They last a long time if they’re not abused.
