Well, Unorthodox makes a nice flywheel as well as the lightened mazdaspeed one, however I don't see any aftermarket reinforced clutches yet.
UNORTHODOX RACING Flywheel With Integrated Counterweight and Hardware Mazda RX-8
Regular price: $699.00
However, the WRX is the same beast in respect to the tranny, which is the weakness of the subaru's. The motor is so plyable with power upgrades and is really solid but it eats five speeds for breakfast. Just ahve to wait for clutch's to start coming out and hopefully, reinforced gears.
Did the 93 RX7's have 6 speeds? Maybe one can be transplanted as existing parts for them are plentiful.
Actually, did a little diggin and it seems SRmotorsports is making a clutch that takes 100% more power then the stock clutch:

Also, ACT is coming out with an RX-8 clutch soon to, just a matter of time before parts are available to fix all of the 8's slight design holes.

i think you should add a little more time to your poll.. unless someone does something really stupid.. these stock turbos should last a while..i would guess way more than a year...assuming people don't f*ck around and do stuff they shouldn't.. like ungodly upping the boost.. but..sad to say..i'm sure someone out there with no brains and money burnin a hole in their pocket is going to try it....
...when one does go... what do you think it will be like? big boom? pop fizzle? whirrrrrrrrrrrrrrrrr...r..r..r....cough? any ideas? or maybe one that's boosted AND juiced...hmm...

Oct 28, 2003 - present = 3 months. ~1500 miles at 7psi of boost, daily driven... I'm into aggressive acceleration and wastegate chatter, but I'm not an aggressive driver, so who knows...

It all depends
At a 10:1 compression, the engines should be safe for up to 12 psi of boost, if tuned properly. I foresee a whole lot of other problems like heat wear and tear and transmission, but as stated, the most common problem will probably be the clutch.
GReddy wouldn't release a kit without proper durability testing, so I'm betting that those with the 5 psi kit that leave it there with proper tuning shouldn't see any problems at all, and might actually get better gas mileage since they're tuning the fuel maps and leaning them out.

I think people with the stock flywheel are more likely to hurt the transmission than those who go lightweight (or light interia)
Its the stored energy from the flywheel that is killer on the transmission from hard lauches and that stored energy is the same whether it is a NA or turbo. In simple terms, stored energy is based on launch RPM (squared) X the moment of the flywheel.
Blown engines? don't know, but the transmission will hold for 5-7PSI turbo apps as long as that damn stock flywheel is replaced.

i.e. catch can if you were following my install thread. I am surprised my stock clutch hasn't blown yet. It's not slipping at all, and it even still grabs in neutral when I let out the clutch pedal, so it's still in top shape. Maybe the stock clutch is better than we originally thought.

Well I almost blew mine on the dyno when it stareted to detonate at 4K. Turned out I had bad software. Returned it to Greddy, and ran it again. No issues this time, & it seems to run just fine. Kind've hairy there for about a sec. or 2.

The beauty of a turbo is that it hits hard in the midrange where this car needs power - low end and top end are fine.
As far as stock flywheel being more stressful on the tranny - no way. I've seen so many cars blow their trannies once they start swapping out flywheels because they rev so quickly the transmission is placed under a lot more stress off the line, and the trannies just dump.
Plus, and I've said it in 100000 threads, a lightweight flywheel destroys the car's driveability. I will never EVER put one in any of my cars ever again.

SR motorsports seems to have flywheels and 2 different levels of clutches available with higher ratings
http://www.srmotorsports.com/RX8_Clutch_Flywheels.html
Seems kind of pricey, anybody have this flywheel?

Definitely a good sign. I expected by now someone would turn up the boost a bit too high and then...pop.
That would make me wrong about my guess on this thread.

I have to admit...I thought we'd have some action by now. I think it shows how conservative the Greddy tuning is on this unit. Good on them 60Hp and good price...and reliable performance......lloks like I'll have to get on the bus
(I am still waiting for RP though...I'm interested in the AFSC)
