I need to change my tranny and the RX8 tranny is like new with 6 speed with short speed....sorry I dont know what is the name for this in english.
Can I install the RX-8 6 speed transmission into my 2nd Gen RX-7?
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 gas mileage at highway speeds.
Using a RX-8 tranny would be like adding a extra gear between 2nd and 3rd to a standard 2nd gen RX-7 M or R type transmission.
Add in, that the RX-8 6 speed transmission is also about 4 inches too short, forcing you either to relocate the shifter 4 inches forward in the car, or move the engine 4 inches backward (towards the firewall) to make it fit in the stock shifter location.

in the end I think I'm just gonna go with a G-force or something to that tune. I've spent Tons of cash on making power....I might as well put the close to the same amount making the power go! Something Cryo'd and coated for friction, with a really low top gear. WHY NOT? Hell It's only money.

Lives on the Forum
You can hem and haw all you want about how OTHER people were able to use the transmission, but I would hedge my bets with a turbo transmission myself.
Does OS Giken make an upgrade gear set for the RX-8 transmission? NO.
Does GURU make an upgrade gear set for the RX-8 transmission? NO.
And please don't get all bent out of shape & butt-hurt becuase someone goes ahead and provides fact that proves you wrong or disagrees with your OPINION. God forbid someone should disagree with the great Ted of many avatars. My graph shows that they didn't just stick a gear in between two existing ones which you and a few other high post count people on this forum seem to stick by as fact.
Do you see the bolded red? Does the graph support that? My graph proves that ALL the gears are tighter. Should I draw you a picture to what you are discribing? Almost the same and the same are different by definition. "Almost exactely" huh? I wouldn't depend on one of your engines in a race. It takes a man to admit when he's wrong - can you do that?

I guess my graph analysis skills are fucked, cause I'm pretty sure you're conclusions were wrong...
You don't know what the **** you're talking about regarding this subject and when someone disagrees with the "great" Ted, you start calling people names and change your avatar.
You're the stubborn donkey that can't see my point.
You're so stuck on trying to prove me wrong, that you're blinded by your own obsession.
**** it.
You're a waste of time, so you go on the ignore list too.

When you're trying to shoot for 500+ hp, an SE3P (still stubborn about calling it an FE?) is just NOT an option.

You'll need an FD clutch, custom driveshaft, probably the starter as well, you'll have to wire it, and have a ustom mount fabricated, then you pray the shifter comes out in the right spot, probably need the rx-8 slave cylinder too.
If this is what you want to do, do it, however, i think the cruise rpms are higher in 6th gear.

WOW - whoe's telling you lies that you are further spreading?
Wrong - "Turbo" clutch
Yes - covered
Yes - covered
How? FE uses ABS sensors as for speed sensors
Covered
Unless you have the ability to massage firewalls and remount engines with prayer - don't bother becuase it doesn't fit
Wrong. Why say "probably" if you don't know?
They will be, been covered.

I've always interpreted sticking another gear in between two others as having one more gear through a range. Not 1st, 2nd, 2nd and a half, 3rd, 4th and 5th but having three gears (and renaming 4th to 5th), instead of two gears between 1st and 4th.

Um... as you can see from the graphs I showed, the RX-8 tranny essentially gives you 1st, 2nd, 3rd, 4th, 4-1/2th and 5th, plus a higher final drive ratio. Just install a higher final drive ratio and forget about the RX-8 tranny. That is unless you have a hankering for an extra gear between 4th and 5th.
