rx8 tranny on rx-7??
 

its prob a stupid question but i was jus wondering.. can i get a 6-speed tranny 4rm a rx8 and put it on my 89 gtu?? or i cant cuz it wont be able to go to 6th gear?? that would be kinda cool if u can so it tho! thik about it a 6-speed 2nd gen.. :101384_l:

i know you can swap the gears out of a miata tranny in to a fc tranny thats what my project for next spring is.

i dont really think that wold work very well

i was reading an old thread on this and people were saying that the TII trans is more durable.

as covered before (please search before posting- this has been covered quiet a few times).

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.

it would be like adding a extra gear between 2nd and 3rd.

Here prehaps this would help:

Much more. People have killed rx8 transmissions with less than 300rwhp.

how do the FD trannys hold up vs. a TII?

Icemark strikes again. Just get a tII tranny there a dime a dozen.


.

They are fairly close... I've heard reports of the TII being a bit stronger for various reasons.

neh...no real difference betwen the FD and FC transmissions except one is push type and the other is pull.

The rx8 transmission has a speed sensor IIRC so you would have to figure out what to do with your speedometer cable. probably switch to the rx8 gauge cluster...

Also as Icemark said...no real benefit to the 6 speed.

If you want a 6 speed transmission, you could always get the HKS dogmission.....for about 6 grand...

Oh, BTW....please type normally...it hurts my eyes reading posts like yours...enough of the MaD tYtE y0 talk...

okay, RX-8's are SE's.

(well just to crap all over this thread with something that does not apply to the question:)

Not according to the VIN. Go look at a RX-8 VIN

[Shakes head] In my book people that call it a SE or SE3P are ones that just can't accept that the RX-8 is the replacement for the RX-7.

Calling the 8 a SE3P is like calling the FC a P747

uhhhhh :icon_tup: ??? (confused)

Just to stur it up, about 2 years ago I read in a NZ/Australian car mag about a prototype 4TH gen RX7, it looked similiar to the RX8, but without the rear doors, alos was powered by a twin rotor called the 16B wide rotor, never heard anything else so just magazine hype

if your car doesnt have alot of power, > around 300-350, shorter gaps between the gears will results in faster lap times in autox tracks and depending on the course possibly faster times around a track. but you would get worse fuel milage.

Not unless they are properly geared for your car. otherwise youll probably waste time in between shifts and end up at the wrong RPM.

I like the idea of a custom bellhousing adaptor that lets you custom order a Currie 6 speed to your specs!

yea true idealy when you shift you should drop to the bottom of your powerband. if you are shifting before or past it you arent getting all the acceleration you should be.

Actually i think you ment to say that when you shift you want to be right at or below your engines maximum torque.

oops... but yea when i said powerband i ment torque not hp...

:molepoke:
I knew what you ment...

Also for you keeping track at home, heres the formula to figure out the "sweet spot" for your car.

New RPM= Old RPM* (New Gear ratio/Old Gear ratio)

more gears stuffed into a similar sized case and longer input/output shafts= weaker transmission.

as said, you will lose time shifting more.

this "mod" is just for bling.

I thought I read a while back that mazda was going to bring back the rx-7 if the rx-8 did well. And it certainly did well, at least around here. Maybe we'll see a prototype in a car show sometime soon. I'd also go for the supercharged mazdaspeed rx-8 I saw somewhere.

I always heard mazda was going to come back out with the RX-7 between 06-08 with a 13B TT model base and a 20b tt luxary model. Damn. All just rumors on bringing back the RX-7. Plus pics I seen of the 4th gen RX-7 kinda looked like a vette/viper. Hate rumors.

indeed perfect example:

top fuel drag

they have one gear and like 9 clutch plates. well and reverse
