renesis in an fd?

Still a waste of time and money. The FD engine can do 300hp in its sleep with bad plugs.
I have seen a japaness article about a tuner overseas fuseing two renesis engines together for a 4 rotor and installing it in a fd, but it still didn't make over 450rwhp.

it'll be turbo, but i'd go to the ref to get the # before i put the turbo on.
rocking, why would you think it's a waste of time and money? this isn't about hp, it's about overall powerband, fuel economy, smog, etc...
if all i wanted was power i'd just turn up the boost on my t66.

other than you can get 230 hp to the flywheel (180-200whp) in n/a form stock and with the higher torque that comes with it.
and higher hp and tq with lower boost levels than the REW as well as lower emissions and better fuel economy (flame me!)
If I had the money I'd do it!
Puertorricans have been able to extract 450 hp out of it so whoever did that 4-rotor didn't tune it worth a crap.

more torque than any n/a 2 rotor, sure, but less torque than even the shittiest TII.

waste of time..i'm a tech at mazda and i abosolutly hate the rx-8 that motor is soo under powered! To me i dont think the rx-8 deserves the right to wear a RX badge when you think RX you think pure sports car not a 4 seater tourer. the Mazda 6 has better power than the rx-8 and also handles amazing! and thats a 4 door family car! putting rx-8 motor in a fd would be a waste of time i think just me .02
even if it was turbo charged it would never make the amount of power a 13b-rew would make. Also you think that rx-8 wil pass smog after you do turbo it? Some guys are just passing smog as it is with just exhaust and intake and simple bolt-ons on thier rx-8
don;t forget when u turbo it that means more gasses coing out, managemnt that you have tune perfectly, etc..

you dont buy an rx7 for fuel economy. these motors can be build in upwards of 600whp thats perfectly fine, and most of us could never afford that anyway. rotary engines are dirty polluting machines so for them to make a rotary enging to be able to pass emissions must have been detuned and altered to not perform well (hense the wimpy power it makes). greddy has a turbo kit for the rx8 thats smog legal but it still sucked on the dyno!
they made the car i believe as a statement that it could be done again and be clean not to make globs of power. dont get me wrong the things are great handling yet if you buy it dont look for big power just drive it in the twisties and enjoy the powerband it has.

In Japan, where the FD DID have a good repuation and sold very well for over a decade, Mazda came out w/ a Mazdaspeed version of the RX-8 that was supercharged. Only a few units were made, but they sold like hotcakes.
In short, Mazda has NO plans to force induce the rotary for quite a while until they undo the damaged rep of the rotary from the FD, and establish beyond a doubt that the rotary is and can be reliable and environmentally friendly.

I've tossed the idea around with a few friends before. The 13B-REW is a nightmare, and if I went through the pain and drama of a blown engine, a N/A solution wouldn't sound too bad.
The upside would be less weight (less nonsense on the longblock), the ability to use the RX-8's 6-speed (assuming custom fabrication could make it work) and the reliability that comes with dumping the turbos and its overcomplicated setup.
The obvious downside is the loss of power and torque. The weight loss going to a Renesis would not make up for this.
Putting a turbo on the Renesis (at this point in time) just crapped all over the biggest draw to the concept. The aftermarket engine management available at the moment is immature at best.

There was a ton of talk about this when the RX-8 was first released. IIRC one of the milestones to over come included something special about the ECU wiring. Either way there is already a ton of debate about this subject and as far as I know it hasn't been done yet.

I suppose you've never heard of the RX-4 Wagon. Hmm? Didn't think so. So, I guess all the Tech's at Mazda really ARE dolts...dude, if you don't realize the beauty of the RX-8, you don't deserve a seat on the Mazda throne.
Oh no! It's underpowered! Oh no, you can control it under ANY circumstance! Back end comes out? You can control it, with very limited skill! Understeer? You can control it, with very limited skill! Oh, whats that? You pulled the e-brake going 30mph? Odd, you can completely control the car. No spin-outs here. The suspension geometry on the RX-8 is amazing, hands down.
If you think the Mazda 6 has more power then RX-8...ROFL. ROFL ROFL ROFL ROFL ROFL.
I'm pretty sure ALL modded turbo cars have problems passing emissions. The RX-8 is not different...they didn't make a new breed of turbos just for it. And..ALL turbo management systems should be tuned "perfectly" .... the RX-8 is not special here. I suppose you think just because you put some 3mm seals on an FD, you are free to tune to whatever you feel like doing. NO.

i got a friend stuffing in RX7 seals into Renesis. Greddy Bolt on turbo kit with large front mount IC.
the progress is still on the way. horse power is unknown.
he's doing that because he blew his stock renesis with greddy bolt on.
the advantage of going that... is he still has his traction control and stability stuff usable...
he has a comfy car with almost the powerful stuff in RX7...

I never though about why Mazda brought back the 8 the way it is till you posted that. It makes snece. But I think the biggest problem with the rotary programs is MNOA doesn't support it. I can't remeber when was the last time I saw a RX-8 commercial.
Now I was think about this swap also. There is finally ECU reflash capabilities now, but if you where looking for a swap you be better with a aftermarket type ECU. More power have been extracted out of the Renesis this way (yes about 300 whp) But with the original ECU reflashed, catback and intake 235 whp were achived just recently. The new Greddy Turbo kit (Emanage Ultimate) has improved also a few people have made the original kit a lot better by change some of the wiring and vacumm around.

if it's some to say they make a mistake that would be me yes i forgot about the rx wagen and the rx-3 and such.
and i didn;t mean the mazda speed 6 has better handling than the rx-8 the rx-8 has amazing i;m just talkin in a package the mazda 6 is a greater car i thin especially with the mazda speed suspension you can from the dealer for the speed 6 now.
i just feel when i drive the rx-8 it's not a tru sports car thats all
