Personally I don't see the point. I have been running a RX-8 5 speed ( basically an FD tranny with different bellhousing and tailshaft) at more than 500 WHP and haven't hd issues yet. Basically you can break anything...but with just a bit of care the 5 speed seems to tolerate 500 without issues
The 6 speed on the other hand....at 425+ you are living on borrowed time so start looking now

How does the 6 speed feel with the rew? I have a custom built one with billet sincro-mesh gears that i ran 450whp with on my rx8 without issues but switching to rew and dont really wanna build a new trans

I know that the 6 speed might not last long and people usually get the JDM 5 speed one because its similar to the FD3S transmission. But I am just going to use my 6 speed temporarily. Maybe you can go with the S2 transmission?

You can run a T56...but will have to do a TON of fabricating to get it to work...including re-doing the transmission tunnel because it won't fit properly....and fabricating mounts for both the tranny and diff...and building a new driveshaft

Dan you're in BC right? Where did you get your 5sp RX8 trans from? I haven't even started looking for one yet, but I read your comment and if I could find one in Canada that would be a mega bonus. I am also planning to run with the 6sp for now but I'm aiming for 450 whp so....

The RX8 5-spd drives better than the FD3 version because the first three gears have been upgraded to triple synchros like the 6-spd has. They sell them new now through Mazda Motorsports, but it’s a bit steep even for new; maybe $2600 or something. I saw the bellhousing only listed too (mid $350 range) but not the tailshaft. Probably marketing those for RX7 push clutch conversions.
I’m working on possibly obtaining another used PAR dog-engagement gearset, this one for the S1 AZ 6 spd. It’s only going to suitable for track though due to radical close ratio changes. 1st is steeper than the OE 2nd gear.
No drag starts with that, lol. It was originally bought for an NA13BPP engine in an RX8 chassis.
