Turbo project...
I keep telling myself that Roxy is more of a "grown-up" car than my Evo...but I still wanna mod the shit out of it. I miss the feeling in my butt-dyno when I reflashed my ECU and turned up the boost on track days. I miss the whine of the turbo and the <pssht> of the blow-off valve...
So I begin my journey towards snailing. I've got mild experience with turbocharging a naturally aspirated car, and ALOT of experience tuning turbo cars. This will serve as my compilation/notes station. I'll chart the journey from start to finish here, and by the time it's done, I hope to have a daily driven 300 hp on a steady curve (as steady as a turbo will allow). I would definately appreciate any advice and help that anyone wants to give. Phase 1: Research Phase 2: Compilation of Parts/Accessories Phase 3: Installation Phase 4: Testing/Tuning Phase 5: Zoom-Zoom |
Phase 1: Research
I'll start with this: How Rotary Engines Work Can anyone offer advice on the best Series I turbo builds? Hopefully by the end of Phase 1 someone will have come up with a tuning solution...if not this will take a lot longer. |
All the answers are here on the forum . Have a read up and then ask specific questions and i'm sure you will get all the help you need ...

You siggy says 09 White GT, do you have a series 1 and series 2 rx8? |
Yeah - if it's a series 2 you may be shit out of luck ....

This isn't going to be a quick process...I'm gonna take my time, work with a few different mounting options, etc... Research includes measurements. |
I used the Powermod from Aus on my turbo for a while and it worked well (although not as good as flash tuning) . I recently asked the guy who developed it for info on S2s so will let you know if he comes back with anything ....

Have some info back on the Powermod . The guy has not tested on a S2 but is willing to help if we want to try fit one .
I know where you could get one 2nd hand at a good price if you want to give it a go .... |

I mean, until the kinks are worked out, I'd be hitching a ride to work/class everyday, haha. Why can't everyone just be as cool as Mitsubishi and Subaru and just keep their ECUs open for tuning? I mean, it's not like Mazda's responsible for something messing up...and they'd get more service business from people who DID fuck something up, haha... |
I am in the same phase you are. I have been reading up and have sent about 10 emails to various vendors looking for a tuning option. Tagging along and I'll post any info that I can find on the subject.

dont understand what you mean by "keep their ECU open for tuning". With a COBB AP you can tune the ECU till your heart's content...
Last time I spoke with them, they didn't have a unit for the Series II. |
ahhhh.. missed the series II header... my bad. Yeah, COBB doesnt see the potential for designing an AP for the II.. a shame really.
|
The guys over at Turblown seem to have a turbo / custom ecu solution but it isn't cheap. I don't know anything about it at this point.

Alright, guys I've been reading over a whole bunch of info on Rotaries, N/A -> Turbo conversions (again...), and Engine Management...
I'm going nowhere with this build until there's a reliable, non-self correcting way to tune this engine... Brettus, you got any more info on PowerMod? |

Currently all you can do is go full standalone; ie haltech, motec, etc...
We were the first shop in all of North America to run the Motec M2r outside of motec usa; it is a good route, just kinda spendy for a street car.. |
I'm thinking about scrapping this project. I've reached my wits end waiting on someone to release something worthwhile, and after some thought, realized this:
- Mods would create a lot of downtime. - Still under Factory warranty, mods would void it. - Looks great as she is, and is powerful and handles extremely well for a street car I'm thinking she's gonna be my street/show car. Looking into an M'z Custom kit and R3 Skirts and some new wheels with a drop. Intake/Exhaust will be the extent of her power mods. But don't give up on me yet! I'm also looking at this, or something like it... |
What a Wimp.......:uhh:
