Rx7 FC non-turbo s4 transmission max power?

Hello. I have an '88 Rx7 FC turbo pushing around 430 whp and 340 ft/lbs. How long will my stock s4 5 speed last? Am I driving a ticking time bomb or is this ok?

it depends on how you drive, and what kind of shape its in to begin with.

i'm easy on cars, i would have no problems. however if you beat on it, it will break

As long as you're not dumping the clutch for burnouts, hard launching it all the time, clutch kicking, or aggressively shifting under heavy load all the time, you'll be fine for a while. As I found out though, it will eventually give up the ghost even if you are reasonable.
