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.
Well... since no one picked this up I guess I'll point out the fact that this was edited by Aaron, not the OP. Check the post.

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.

When you're trying to shoot for 500+ hp, an SE3P (still stubborn about calling it an FE?) is just NOT an option.
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?
Wow, still "butt hurt" about 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.
I really don't care what others agree with.
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.

Who said ANYTHING about 500+hp? You're inserting little facts into statements in an effort to prove yourself right becuase you cannot admit when you're wrong. You said clearly all they did was stick one gear in between 2 existing. My graph proves you wrong but you can't admit that. If gears end up in the middle of two existing ones becuase all the other ratios were tightened, that's something totally different. Going back to that almost the same is not the same. Did you almost **** the prom queen? Are you going to brag about almost doing something? NO - becuase almost = FAIL. I never said that the FE trans was stronger that the Type R. I said it wasn't as weak as people bitch and moan about after its been rebuilt and modded by a competent shop and then driven decently.

No - as said above - if gears fall in the middle of existing ones becuase all others were tightened, it's completely different than randomly sticking a gear between two existing ones. 1st in the FE is ALMOST the same as the Type R, but it's NOT THE SAME is it? NO Just like second, just like they didn't stick a gear between two.

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.

How? FE uses ABS sensors as for speed sensors

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?

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.
