3 rotor rx-8

A Mazda RX-8 is powerful in its own rights, but if you really want something that will get up and go and keep you from breathing for that 10-12 sec down the quarter mile, do as Acosta Motorsports in Wallington, NJ, did. they took a stock RX-8, left the interior stock, but put on some after market body effects, oh, and a tri-rotor engine that boosted the horsepower from 248 to a whoping 950! also under the hood is a T-80 dual ball bearing turbo, Acosta header, TiAL 46mm wastegate, Garrett intercooler, TiAl blow-off valve, custom ram air, and more.

What do you think of that, speed enthusiests?

wow, they've been doing the cosmos three rotor engine swap for many years now on the rx-7. and they've been able to pull out a lot more than 950hp. combine that with the superiour rx-7 and it will blow away that rx-8.

ahh since you have seen that maybe you can answer my question..thres three rotors......right ...then why on the headers is there 6 pipes on them? I hope i phrazed this right to understand because i ask this on the rx-7 forum 2 and they gave me good info but not wat i was lookin for.because i figured 2 rotors 2 header pipes 3 rotors 3 header pipes.

Acosta did it on all stock internals. They debuted the car @ the Nov 2003 SEMA this year. I believe it was 850WHP. That's not bad on a stock inside. I forget the management they used, Modified mag talked about it all in a recent issue.

Are you talking about the intake runners ontop of the engine FRIMX?

The FD has 4 runners, and the 20b's have 6. Each rotor gets 2 runners.

each rotor has two exhaust ports, therefor it needs that many

Each rotor has two intake ports, a primary and secondary.

Oh wow he really got you on that one damn don't you feel a little dumb posting somthing you had know idea about? By the way thats a hell of an engine there were could I get one?

Why the hell is there an Eclipse on this forum? Lets see this is the Mazda forum right lets check real quick... yup

Wow, you're nice... I suppose since I drive a Toyota im not allowed here too?

We're supposed to be bringing together the automotive communities for mutual benefit and discussion, dick.

im sure its cool and fast but, i couldn't afford a 60-70k$$ mazda rx8.they should come with that 3-rotary motor, the cheap fuckers.

jeez, settle down dude you might learn something from other people.thats what this is all about. :wink:

20b swaps cost in the 10-15k range if you do all the work yourself and have skills to perform custom fabrication. and this is the kinda basic swap with no *real* performance to justify the cost of the swap.
shops are asking 30k$ and they turn a 3rd gen rx7 in a 500hp 20b reliable beast.

and the rx8's suspension design is superior to the one used in the FD

anyone notice this thread is a year old?

60-70K?? What prices have you been looking at. An RX-8 cost no where near 60-70K new. They are in the 30K range typically new. Also, you'd never find a stock the RX-7 here with a 3-Rotor...why?? They never even came with a 3-Rotor, The 3-Rotor motor is a JDM motor from the mid-90's. Why expect a used JDM motor from the mid-90's that never was sold in a car here...even in the beloved RX-7...to be place in the RX-8. Granted though, if they re-designed the 3-Rotor and stuck one stock in an RX-8, it would have been a pretty kick ass.

i think he meant the car from acosta motorsports
not any dealer rx8.
rx8-30 g's
20b-40 g's installed/tuned
= 70 g's

I have caravan with the 3 rotor rx8 to rotorfest and its no
comparison in power to our cars.especially with there jic coilovers
and custom exhaust.not to mention the spitting fire balls.
