so i have a problem. i have an extra rotary engine, no more rx7, but a a 96 eclipse with a blown engine. so............. im thinking about doing something crazy like rebuilding the rotary and doing serious modifications to the eclipse and putting it in there. how crazy awesome would that be. and there isnt any real point to doing this other than just to do something rediculously awesomely crazy cool.

 

good luck...tell us all about your failure and wasted money.... lol

 

A fwd 13b? Sounds like a piece of cake

 

I see now reason that it couldn't be rwd. Should already have the room for the driveshaft.

 

I've seen a 13B rwd Mx-3, sure it's fast, but it's still just an Mx-3

 

lol i actually like mx-3's. but anyways.. ya it would be a rear wheel drive. no way id have a front wheel drive anything anymore. and i dont see why it would a failure, or even be super expensive.my dad has a metal shop so i can fabricate all the mounts myself for the engine and tranny and rear end. and the rest is just cutting the tunnel and back halving the rear.

 

Post pics when the car is running, good luck!

 

lol... I think it's a cool idea.. I almost swaped a t2 engine and tranny into a 240 for the hell of it... shouldn't be too hard either... the tunnel should be there already thanks to the awd version... just gonna need a standalone and custom mounts and custom drive shaft.

 

lol im glad ur with me jumbogumbp. you totally understand the "why the hell not" of this situation. lol. now if only i could make a 4 rotor. lol. that would just be freakn wicked as hell. but thats prolly even more of a pipe dream than the conversion itself. but why not. i'll have a week off in july, and every weekend (once it warms up) till then to do it. it shouldnt take to long to convert. but the only bad thing is i dont think anyone around here can help me tune it. cuz i dont know anything about standalones.. and i mean nothing. and i doubt anyone else does either. i need to contact some people in the kentucky region rx7 owners clubs and see if anyone does. lol. but i'll worry about that when i get to it. i first gotta worry about getting it in there.

 

well as far as standalones go.... if you keep the motor stock and get a haltech you can just download base maps that'll be close to what you will need... tuning is all about the a/f ratio your goal is to keep it close to optimal in all rpms...at any given psi..at whatever elev. and temp. at any given load....lol thats it.
Personally I think swaps like this are fun.... just for the sake of doing something you arn't used to.... I've had 7 fc's and 1 fd and when I was debating on doing the rotory in a 240 swap, it was cause I had a spare streetported s4 motor and a s13 chassis sitting around so I thought what the hell could be fun!.... but I sold the chassis like a week later to one of my drift team members.... then decided to build a sand rail using the motor.... but sold it like 3 weeks after.
Now I'm thinking about making a sandrail out of an ej22t..... that I was gonna use in my project impreza.

 

so i started lookn up the rear end of the awd version. and it looks pretty simular to the rx7's. im not saying i want to use it or anything, im just saying it should go up relatively easy and i wouldnt have to back half the car. which is good.

 

Do it !!....id`e like to see that

 

Its too bad that your stuck with an eclipse as your only option, but hell! go for it, that would be cool to see! It might be the first eclipse that I give props to....

 

so the eclipse rear end i found at a decent price.... and obviously wouldnt require modifications.. so i looked up the gear ratio and its a 3.545. which if im thinking right.. means id have a lil better top end, a lil better gas milage, but would lose some in the low end. but since the the rx7 is in complete lack of a low end..lol.. then what does it matter. it just means in race type situations im just gonna have to take off revved a lil higher than before really. and would probably have a quicker 1/4 mile time. since im gonna have to have a custom drive shaft made anyways.. i'll just have one made to fit that. lol. sounds easy enough. i found a guy in town that does drive shafts. sounds like all i need is motor and tranny mounts.and prolly widen the tunnel in the front half for the tranny maybe. the only thing that really keeps this idea going is just the simple fact ive never heard of it being done. cuz i mean honestly .. who would actually do it. lol. let me tell u tho. .. this project would be so much worth it if i could build the 4 rotor..lol. grannysspeedshop.com makes it look so easy its tempting. the only part that makes it challenging really is the ballencers. cuz i can make the crank myself.. correction.. make my dad do it. lol. since he has a lathe and all. or at least be able to join the two like granny's did. cuz he has drill press also.

 

oh and dank. im not to upset its goin into an eclipse..ya its a horrible form of bastardizing..but hey.. parts for the eclipse are a dime a dozen on ebay.

 

I can't find it now but i saw a FWD rotary civic once. I could've cried- and that was before i owned a rotor-motor.

 

HMMM I think that gear ratio blows...get a new rear pinion.... ever ride in an auto fd with the 3.9 rear? it blows, a 3.5 would suck MUCH worse. if you had that rear god only knows 5th gear on the highway would probably be idleing. I'm not sure of the tranny gear sizes to do the math... but it will take you years to get through each gear... can you say 65 in first lol.
Anyhow my point is get a 4.11 rear and you'll love the exceleration. Think of this, bad gearing+heavy body (heard those were like 3200lbs)+no power under 3500 rpms= not a fun car.

 

Your in a position kinda like me realy....not realy but I do have a 99 eclipse gs for a daily driver and i swaped my gxl with a s5 t2 sooo...but yeah dude, rotary in a rwd eclipse would be tight =D I've already seen a rwd eclipse before but this will blow it out of the water for sure, but yeah shouldnt be TOO hard, its all realistic. I say go for it.

 

Fastest 240 EVAR!

 

uhm... the 240 was never awd. hicas sure- but never awd. the tunnel for the ka24 trans should be larger than the 13b trans.

 

I think a rotary powered Eclipse would be pretty cool. I don't think I'd drive or own it, but it'd be pretty cool. And a 13B-REW all wheel drive Eclipse would be ridiculously good for grip. *cough cough* Track, anyone?

I'd be very interested in seeing that car on the road. Good luck with your project, and post some pics and stats when your done!

 

you need to do some more searching... i know a lil bit about dsm's and the GSX is a lil diff from all the other models... there are ppl that own gst's and try to turn them in to gsx.. nothing bolts up in the rear.. i belave it was said its alot cheeper to sell the gst and buy a gsx... so if you are just thinking aobut swaping the gsx rear end in the gs body it wont happen with out lots and lots of fab work.. the mone yand time that is spent on it you oculd have put a good rear end in it...9" or 8.8 or

i would hate to see you start on a project like this just to find out stuff wont bolt up...

i say do it it would be cool.. or you could get a GSX car and get a adpator plate made to have a AWD rotary no that would be cool

 

An awd rotary via a eclipse GSX.

What would be the point, rotaries are supposed to blow up the engines themselves all the time, not the trannies.

It'd be easier to do in a wrx or a skyline since the engine faces the right direction.

the way the engine faces wouldint make it any ez'er or harder.. either way its a trans adaptor and motor mount... to got the AWD route

and im not sure what you mean by
