Nice! What steered you to the TrueTrac instead of something with a higher bias like the T2R?
don't make me lie or embarrass myself. I dont entirely know what higher bias really means. I was originally going to get a ford performance carbon clutch but after some lengthy reading, the trutrac was the better option. It's also what keisler recommends. This car will never see a race course in any serious capacity so I'll never see the real benefit of something higher imo. It just needs to hold 600hp for laughs on the freeway lol.
One thing I can say is the car runs and always has lol. Definitely needs a real tune since it's basically on a start up tune. The problem now is once its road legal again I'm torn between driving it for a while or diving right into this transmission conversion and having it all tune together one time vs repeated tunes.
Hopefully people can learn from this build thread because the struggle for information is real 😅. i post on supra forums for the 2jz information which is great until the transmission discussion. Ive received bits of info from rx8club as a whole but alot of one on one info from specific users. This swap is way out in the weeds and not for everyone but I think there's someone for everyone in it.
Just a side note. When purchasing this diff kit, it ask you which generation rx8 you have because the sunframe design changes where the front section bolts on. Supposedly the s1 is different from s2. My 09 r3 subframe matches the spare subframe I pulled off an 06. Maybe the changeover happened later or maybe my 09 is a late 08. There's pictures on their website showing the difference but it's not easy to see on the car itself.

You'd likely never notice the difference unless on a tight autox course, and if tracking sometimes open diff is better. For a street car, no one would know the wiser.

whachatalkinabout noob?
anybody taking your RX8 advice gets what they deserve.

there’s nothing to debate or argue over, but seeing as how you swallowed it hook line and sinker then consider it good advice for yourself.

pretty sure I'm entitled make my own choices in life which i already did prior to his post. Slandering his opinion without at the very least providing a counter argument in support of your own opinion masqurading as fact is completely useless. Go be the misinformation police elsewhere sir .
I'm sure you have done your research and picked an option that fits your needs, it's a reliable diff that should serve you well. No point spending more money on something if your usage doesn't match the product application.

Do you even hear yourself? I’m not interested in arguing with either of you, but you sure seem to be trying to pick a fight with me, while at the same time pretendng like you don’t want me replying here, and also at the same time pretending to be cordial when you’re not. In order for it to be slander then it’d have to be untrue. If anything is clear in your replies, it's that you’re not the least bit interested in whether it is true or not.
The part you’re not getting is that anyone with enough RX8 experience recognized it for their self.
.
You're entirely correct. Idgaf if it's correct or not because my decision was already made. I agreed that i wouldnt be able to tell a difference. I honestly dont care nor, did i ask for anyones "rx8 experience" in this matter lol. I appreciate everyone whose willing to share their thoughts, opinions and experiences nonetheless
Why you feel the need to plague this forum with your nonsense all day everyday has been beyond me since I joined this forum. You've contributed absolutely nothing of value in this thread yet still find the need to express disdain for other people's input. You're also correct that I'm not being cordial, but that doesn't mean I need to result to name calling and noob trolling like you're attempting to do. Its the internet bro, calm down. Go build something with your time good sir
Got started changing out the rear end. Learned the hard way why the S1 rx8 rear subframe is slightly different than the S2. They added a slightly larger gas tank on the S2 which caused a redesign of the front hoop section of the cradle. The thick front adapter bracket creates a slightly uncomfortably close fit to the tank but it still works lol. If you're keeping the mazda diff you won't have any fitment issues.
As you can see it's stock twins which I would tell anyone is a complete waste of time. They fit with minimal modifications but clutter the bay drastically. The main issue is the heat they hold. I don't have any issues with overheating or anything but under hood temps arnt the best. I've since revamped all my cooling situation to regain AC because I live in texas... I'll post how I did/doing that in a few First time out the driveway under its own power back in 21 Engine, trans and diff carrier mounts are one off. I'll take better pictures so you can get a better understanding. The transmission mount sits on a chassis brace we made utilizing the factory brace bolt holes
Hi mate, you've done a great job with your RX8. I'm going to do the same swap but I have the following question: can you tell how the car behaves when you change the engine? Is the weight distribution different? How does it behave in curves? I'm afraid of doing it and then regretting it. I love the stability and dynamics of the RX8. Thanks!

imo the car behaves well. I never had a running rotary to compare the characteristics. The chassis places the weight of the engine pretty low and back to where it's pretty balanced. You can notice the car being a little more heavy when braking. The OEM brakes aren't enough. A good set of coilovers with higher spring rates and dampeners can mitigate most of the weight transfer.
Woah congrats on getting your project fully up and running! I was really curious about progress updates, glad to see the install was a success. Hopefully you'll post a few glamour shots at some point
Thanks man. Project got stuck for a minute with ECU issues and work. Finally got that lined out and now I'm making time to get back it. 8hp is installed along with Ford 8.8 rear and Wildwood calipers. Now to marry the two ecus, bleed the brakes and get it moving under its own power. Soon ..
