Assuming the engine is strong enough to withstand a well tuned FI system, how about the transmission and clutch? Can these stock components handle up to 400whp? What other parts could be negatively affected by the increased power?

thanks

 

At 400+whp, as far as I've learned on this forum, you should consider a built motor (rods, pistons, ...) and aftermarket clutch.

 

tranny yes ,unless you abuse the **** out of it
and clutch yes "for a while", but it will start slipping sooner than later.

There are many inexpensive clutch choices , Clutchmasters Stage3 and JWT to name few that are fine for this power level.

Depending how hard you drive , all driveline parts , ie Diff , half shafts etc etc. are effected by the increased rwhp. Repeated hard drag launches (especially with slicks) will eat there lunch the fastest.
If you launch like granny on street tires , all these components should last a long while.

 

415rwhp on stock clutch for 6000 miles and counting. No transmission problems either.

 

I am still waiting for somebody to buy a set of half shafts from Drive Shaft Shop.

I wonder how well they are designed.. They call it the 350ZX so if they don't know the actualy name of the car it makes me wonder.. lol

 

I believe mjedens has a set that he runs for nitrous with his built motor. No problems with slicks anymore.

 

380rwhp 3200 miles and the clutch is now starting to slip after this weekend's meet, new twin plate to be install ASAP.

Cheers

 

425rwhp and 15000 miles on motor since supercharging.

Did not really "feel" the clutch was slipping, but recently Nissan replaced my tranny for known synchro issue (again!) and put a new redesigned clutch in the car. It became quickly obvious that my old clutch was slipping and probably had been for quite some time.

Now waiting on JUN flywheel so I can put it and a CM III in the car next month.
