how much hp/torque can a stock S5 rear end and transmission take?
 

yes like the subject says, how much hp/torque can the stock S5 rear end and tranny take? an S5 tranny and rear end was put in my current rx7(an 88 TII) by the owner before the previous owner, a friend of mine actually... so i was wondering how much it can handle before snappage... its important for me to know cause i'm gonna be building a high hp TII soon...

I'm asuming it's a turbo tranny and rear end??

well no more then the S4 one. around 400-500hp as long as you aren't too hard on it.

yes, it is
