Can a Rotary fit in a MX-3?

Short answer: Yes. Don't give me that "oh, it was the tube chassis" or whatever, it can and has been done. Yay!

The elder Acosta campaigned a rotary powered Mazda MX-3-bodied tube chassis drag racer in the late nineties and had success in a few championship runs in the import drag racing circuit.

I can't beleive I am actually replying to this idiocy....

WTF dont you understand about a tube chassis? It was custom and could have ANY BODY STYLE attached to it. They were panels that bolted to the cage as a shell ONLY. The ONLY thing it had in common ith the MX-3 was the general shape. He chose the MX-3 because it was small and aerodynamic.



Tube chassis= LITERALLY a chassis made of tubes= not ANYTHING like a street car.

That car had an RX-7 hatch on it too.



I have said this before and I will say it again... ANYTHING can be done with enough money and fabrication skills. Yes, even a Rotary in an MX-3. However, it will not bolt in... there are no parts lists... it will be completely custom. A v8 would probably fit in the engine bay.

So, in simple terms for simpletons... the general answer is NO, it will not "fit" in the sense that it will not be cheap, easy, or bolt in with minimal mods. That is what people mean when they ask if it will "fit."

Geesh.

So NO, it HAS NOT been Done. Yay!


Seriously, this thread needs to be locked or deleted for stupidity.

Custom Tube Chassis





Mx-3 Chassis




Just "a tad" different

There had been a 13b installed in a 323 as FWD, but apparently it's too light and het gets alot of wheelspin

But I'm sure that is as easy to do as a RWD KLZE Miata.

Now that is pretty sweet lookin lol too bad rotories blow up every 50,000 miles hahaha

I met Marcos Acosta while racing in Sacramento five years ago or so. He helped me air up my slicks! I got to sit in his car and it was NOTHING like an mx3 on the inside at all. We were the only two mx-3's at the track! If you could count his as an mx3...

[atlantamx3]

I took these pics of a tube frame SCCA Racing MX-3 a few years ago here at Road Atlanta....

It had a Mazda GLC engine in it and was RWD.

He was running 1st place until he broke a tie-rod on the 2nd lap.


I beleive that this is the same car that Barry or someone bought the fiberglass panels from about a year ago.

You can see just how similar this is to a real MX-3... its NOTHING like it execpt for the shape.

Me and Patdiesal had a chance to watch and talk to Robson earlier this yr. Possibly last yr... This guy dominated his class at Road Atl and was a blast to watch him beat the pants off the competition. Their is one part on his car that IS part of an Mx-3, the roof. The rest was metal tube and fiberglass that resembled the Mx-3.

not true, my rx7 has 145 on the engine and 245 on the car, the engine still has near perfect compression. you just have to maintain them properly and then its all good.

well if my friend can fit a windsor 351 v8 (bigger than all the other v8's people put in theirs and his is closer to 50/50 weight than theirs) in his miata i'm sure if you are willing to put in the same amount of work as him then you could put a rotary in your mx-3.... biggest thing is you'd have to make a custom doghouse behind the dash to give yourself a little more room in the engine bay

A Stock 13B rotary can make over 700HP with no internal mods. The only reason rotary engines blow up is in most part due to to aggressive tuning. It only takes a few light pecks of detination to blow a rotary. With out the detination I'd say hands down it is one of the THE strongest engines EVER produced!

The weak point of the rotary is its apex seals. They will not with stand detination like piston rings. When the apex seals do break they usually take out the rotor housings and end housings making the entire engine scrap metal. Pineapple racing sells a uniquely engineered set of apex seals designed to break at controlled points prevent them from taking out the whole engine. One solution is to use 3mm apex seals which require having the rotors machined to accept them. These seals are MUCH more resistant to detination giving you a safer threshold to tune from. I have a 2nd Gen RX7 with around 150,000 miles on it. I've broken 2 transmissions and had to replace the clutch disc and thats been it. I bought the car with around 118,000 miles on it. I put Racing Beat underdrive dual belt pullies on it, removed the air pump, custom intake with thermal wrap, custom headers with 2.25" primary tubes into 2.5" mid pipe with dual 2.25" rear section. I've thrashed the crap out of it and it won't quit running. It will take Z28 camaros, mustangs, etc all day long still! The NA RX-7 trannies are REALLY weak but the Turbo II drive lines for example will take 600+HP.
