tranny question - Toyota Nation Forum : Toyota Car and Truck Forums

ok i have a question.

how much hp will the stock ae92 GTS tranny handle with an LSD installed? is it even wise to place a 4agze on the 4age tranny or is it smarter to just use the supercharged tranny? i've heard that the gears are really tall and it doesn't shift as smooth as the N/A tranny, and i wanted to do an aftermarket clutch and flywheel on my N/A and don't want to have that go down the drain when i do the swap

or will using a 4agze on the n/a tranny rip the gears apart? i know the axles are smaller right? how much hp will the axles hold on the n/a? thanx ahead of time

not too sure about the ae92, but with the ae86, the t50 is used for both gze and ge platforms.

i would imagine its the same with the fwd. i wouldn't be too concerned with toasting your clutch or drivetrain componenets...remember we're only talking about 140hp up from 118hp. its not a huge jump.

in excess of 200hp..now thats a different story

the trany in my sr5 can take 200hp.....
and in a gts it can take at least 300hp so dont worry .....

ok so u guys think its ok to stick a c51 tranny on a 4agze and not worry bout wasting my money on the flywheel and clutch?

toymaniac · 09-05-2002, 11:30 PM

wich gze are you getting? from a mr2 143hp? or levin 160hp?

just use toyota clutch and flyweel.... a friend of mine as a 91 gts with a hybrid 7agze @ 14 psi 200hp http://www.imagestation.com/album/?i...ulation_page=Y

and he has stock trany, flyweel and clutch......

nick. isn't tranny longevity determined by the amount of torque that the particular tranny can handle, and not HP?

always thought it was torque and not hp that kills a particular tranny that isn't up to task.

i'm not too sure as to which engine, more than likely the levin version but i may go withthe mr2, whichever is handy, i was thinking bout just buyin an entire front clip from a Trueno and swapping it all over but i want to keep the flywheel and clutch i bought for the n/a tranny so thats why i'm wondering if the tranny will hold 200+hp?

good thread for me to post this i geuss but as you might have read in my thread i'm building a 2RZ-fe to make at least 430HP (so it will bre around 385 @ the wheels but do you guys think that the tranny out of a '99~00 Tacoma can take at least 450 lb-ft of torque?

power in itself will kill the drivetrain components. period. but yes, like you said cyril, torque is where most of the damage is done.

in any case, i don't think he has to worry about the synchros being damaged. I think he would want to address the clutch and friction disc. however, if your not exceding 200hp, the oem friction disc and pressujre palte are good enough.

oddly enough, hp and torque are essentially the same thing because they both measure the same thing.

i always thought that tq was what the driver felt, meaning the pull of a car and hp was the engines ability to pull in higher rpms even when the tq is falling off, thats why dynos measure tq and calculate hp as a function of tq.

but n e wayz i wanted to used the upgraded clutch from ACT, with the 90% press plate and the disk made for it on the lightened flywheel so i dont' think the clutch would have a problem holding i was more so worried bout the power, both tq and hp, ripping the tranny apart relatively quickly. i know it would shorten the life of the tranny definately but more so how long do u think it would last with mild driving and not doggin it all to hell, plus throw in an LSD and some redline tranny fluid. do u think the C52 can hang with the power that a 4agze can make with say 14psi and massive amounts of tuning to the engine?
