I was wondering if it was possible to swap a 6 speed rx8 transmission into a s5 gtu.i heard it can be done with not to much of a problem,but i was wondering if anybody else has heard about this or has heard of anyone doing this.well iam all ears so holla back 1.

 

no and search this has been covered before

 

Well i didn,t know it was covered iam not a mind reader.

 

that's why you search first.

 

Yep, this was discussed enough, not worth it really.

 

yea but he missed it first go around. If it is not on a stock car for the most part you will snap that tranny.

 

*chants* close it! close it! close it! close it! close it! close it!

 

rx8 transmissions are apparently no good above 250hp, in the other thread abotu this someone mentioned something about the internals breaking in quite a few rx8's

Turbo II transmission is a reliable "drop in" and is made to handle horsepower, try to get a hold of one.

 

i'm pretty sure that torque is the determining factor in whether or not it breaks, as opposed to hp. torque being an actual force, and hp being some esoteric derivitive measurement that i don't understand.

 

hp is amount of work done over a period of time..

EDIT: theres a great write up somewhere in here, ill find it

Edit #2, couldnt find it, oh well

 

Horse power in cars is a measurement of peak work rate. foot pounds per hour(not sure on the time standard). Torque is a measurement of instantaneous applied force. foot pounds. Something may be able to apply alot of torque for an instant but not maintain that level(high torque low HP) or something may be able to sustain the torque levels somewhat over a long periiod of time and thus have a higher HP rating. If you can flatten or raise your torque curve in the high RPMs then you will substantially increase your HP(eg better air flow, turbo, nos, less moving mass).

 

yeah i know, that the number that being thrown around, hp numbers and what not, anyways, enough hard launches with a significant powered car and you'll break the shitty rx8 tranny

 

Basically past threads have determined that it's not a great idea. I think in an n/a it would cause a big drop in highway fuel economy as well.

 

5th gear on the FE tranny is the same as the 4th on FC trannys anyway, so there is no real advantage of using the RX-8 tranny, and 6th on the FE tranny is actually taller (.83 vs .71) than the FC, resulting in lower mileage.

There really is no reason for this thread to remain open, however if the originator of the thread would like it to remain open, they can PM any 2nd gen moderator to re-open it.

Otherwise... Thread closed.
