You probably won't be able to find a complete 4 rotor for sale. A kit would probably be the easiest route to go and will set you back $9,500. With the price of housings and side plates I would say estimate on about 20-25K for the motor. Getting it to fit I'm sure could be done, though the subframe crossmember will need to be moved forward and since you'll need a custom oil pan anyway you could probably squeeze it in.

Here's a little something to help you out Linky.

Good luck!

 

Ok, I'm reading this thread while partiicipating in a conf call and I just inappropriately snorted while I supressed a laugh over that photo. OMG that's hiliarous!

Ricer meets Engrish!

 

If it was mine it wouldnt be sitting on a cart. Sorry.

 

Thats Australian dollars

2 reman 13b $5,000 and you are good to go, for the block that is, then the hard part begins

Damn now thats some real info right there i hope anyone took out the time to read that, took that guy a long time just to get it to work. Not to mention he had the resources,and the funds Judging by what your asking its just a thought as of now and you have no clue how your going to even going to obtain the motor in the first place, if anything i would just go with a 3 rotor and turbo the hell out of it

 

Hmm, I went to the drags yesterday and there were at least 3 quadrotors there, the mazsport bmw and 2 fd's (i forget who they were)

If you can fit a quadrotor in an FD i dont see why you couldnt do it in an rx8

The problem the quadrotor guys seem to have is trying to tune them

^ I have seen a videos of a bmw and a 3rd gen with 4 rotors...

 

I think you'd spend 20K in electronics and tuning alone once you get the motor IN the car. Hell race teams spend that much about that much to get the same on pushrod V8's nowadays.

 

That motor looks familiar. I can't say where I may have seen it before .

That would have caught a premium a week before Race Wars

 

A turbo 20B isnt enough???

 

I've already decided that I'm gonna try and drop an LS2 engine in mine when it's hooped, I've seen it done on RX-7's sure it'll be a bit of work but i've heard it's possible.

 

Hey Guys

I just make my final decided on 4 rotor motor project set up, I'm goin to order two 13B or wait untill new 16X come out then i will order Two 16X rotor motor to make them in one!

DK RX 8

 

what's your budget?

 

Damn Mazda, they need to make this happen. A 20B Renesis theoretically could produce about 350 crank HP in it's stock form. That would be a nice RX8! I hope one day I have a ton of money as the 4 rotor is very appealing and isn't a crazy idea. A N/A 4 rotor would be nice, you could have tons of reliability (if it was tunned and set up right) and produce tons of HP w/o the need of FI. 2.6L isn't big by any standards, I'm tired of Mazda's B.S. with this 1.3L design. The renesis would be nice in a go kart or a Lotus Elise but they should scrap this 1.6L concept and go bigger. Add at least a 3rd rotor!!!! I love the renesis engine but the RX8 is too heavy of a platform in my opinion. If the car was around 2000 lbs it would be a total blast. Not that the RX8 is bad, but it just seems they could have done more.

 

2 x 13B OR two x 16x is your FINAL decision ?
If that is your final decision what is your final final decision ?

Shaun called it - this has Nalin written all over it .....

 

"Is that your final answer?"

 

I'd like to phone a friend

 

I heard all you need to do is epoxy two 13B engines together and it will work just fine!

 

no no no no, not even that.

the rotors go together like legos. you can just add another on the end. even 2 or 3 or 4 more additional rotors!

 

Oh! Can I make a Star Destroyer with the Rotors, then?! : D
