think of doing like a pineapple mega bridge 4 rotor ? just a though, besides the $15-20k it would probably cost to do it...

 

Good luck man....

Just do your research!!!! plenty of places offer 4rotor parts believe it or not.

an 15-20k isnt too bad if you got a roller in the first place. Its a big bill to think about when you already paid 16k for your car, and your thinking of dumping another 20k of which you'll never get back

 

15-20k you wish. Try again.

 

^ This. From what I've seen, the e-shaft alone will run you 9k. If it only cost 15-20k I'd already have a 4-rotor in my FD.

 

there is a guy in NZ that makes e-shafts for 4 rotors. I think that alone is 8 grand...

 

Its around the same price as doing a NA 3rotor......
Im not talking with a turbo setup.


They actually have a 4 rotor Crank Kit for around 9k.....



If you have the right people helping you I think you can have it all done realistically under 25k

 

All the 4 rotors I've ever personally seen are P Ports, cuz it's hard to make an intake manifold for it I believe I read? Either way with building the motor, tuning and fabrication to get it in the car I'm thinking you're looking at at least 35K

 

the point of doing it would be mainly just to do it, and i paid 400 for my car not 16k, and if i was going to build one i would have rob at pineapple build it for me, 8 second na rotary... just a thought ...

 

You gotta pay to play. And if your going to be paying someone to build the engine and car your looking at over 35k n/a. More for turbo. Doesnt matter if you got a nasty motor setup, if the power isnt getting to the ground then its worthless. Considering under your user name it says rx7 n00b and your starting with a $400 project , i gotta say this is probably a restricted area for you.

Ive learned TONS over the years but even if i had the motor a 4 rotor wouldnt be on my mind(sorta) Its motor detail on internal cooling and ect ect ECT that i cant get into. I myself would LOVE a 3-rotor, 2 rotors are still crazy as ****. You might as well do up something almost as good for tons cheaper and easier.

 

I looked at getting one from NZ same guys that built the engine for MadMike's FD. $26,000 fully built. Now it's just a matter of getting it here and it still being in the box.

 

Lets just say you can get the engine for 26k, then you have to pay for a fuel management system, then you have to have someone custom fabricate an exhaust system, intake system, transmission to be able to take the power, get someone to be able to mount this in a car and keep it from twisting, rearend to be able to keep from blowing up. The list goes on an on and on. Why do you think that there are only a hand full of these engines out there today? When it's all said and done your looking at 40-50k++

 

You might be exaggerating just a bit. It all depends on the power level....
On average 450 seems to be a easy number to reach.... If the OP is going for 600+ then I most defiantly agree with you.

As for a tran's,
if it would be possible to throw a Rx8 6 speed in there that would be a sweet setup.

 

Just watch this. You guys don't even know the torque the 4 rotor makes. No stock trans. will hold this power for any length of time.

Dream on ladies.

 

what is your purpose for a four rotor? Race, Street, show(), or just want **** load of HP? not being sarcastic or anything. If you have money to burn go 3rotors with a big *** turblow...

 

sounds so sexy tho...

 

you could go wit a built tremec t56 and use a ford 9in rear end. both can take pretty much watever u throw at it. both can be had for pretty cheap.

 

Like i said if its 600+...

The scoot 4 rotor is only making around 400.......It really depends on the application.. If I did one It would be more for show and personal enjoyment, Not to have ***** out power.... I would make something that would be as if mazda made a 2010 Rx7....

Similar to Gordons 3rotor NA FD........Sure theres other 3rotors making CRAZY power... But its pretty awesome to have the prestige of a NA 3 rotor that not many have.

 

I've ridden in Gordon's 3-rotor FD. He would be another good source to consult. I can guarantee you though, no matter how much you try to "dumb down" this project, it's going to cost you at least double (more likely triple) the original figure you're budgeting.

 

twas just an idea...

 

Sorry, not trying to be mean...just trying to put things in perspective. This is a massive, massive project you're talking about here. We're just trying to warn you before you get into it and say "Oh ****, I had no idea it'd be this expensive/involved!!!"

 

For a NA set-up, 15k is doable only if you do everything yourself. And I mean everything (fab, tune, rebuild, ect). The labor is what cost so much. You would also have to get very creative on parts sourcing to save money or build everything from scratch. If you got the time and are willing to learn, that's the only way to go to save thousands otherwise, your going to have to open up your pocket book a lot more than 15k.

 

Scoot is still using the Stock Trans
It all depends on your power level

Here's a build from the club
https://www.rx7club.com/rotary-car-performance-77/another-4-rotor-build-788554/

 

Just look around (google/youtube) for a car with the plates 'FOURRE'. It was one of the first cars in NZ to run a regularly street driven 4 rotor PP. It was a series 6 rx7 and the only drive line mod was a twin plate clutch and the guy ran low elevens high tens in it for a season or more. Unsure how much he spent on the rest of it though, I'm picking around 30+K ($NZ). It was making around 570hp.

 

didnt Aaron Cake fab up his own 4 rotor e-shaft?

 

Torque is what breaks the Fd tranny. NA 4 rotor makes great torque but it isn't huge by any means. Plus the torque delivery is very linear.
