AWD Rx7
 

Thought that might get your attention. Toying with the idea of doing the research to develop a 1st gen All Wheel Drive rx7. And yes i would use a rotary engine.
What is your thoughts on this subject? rx7doctor

what would you use for a drive train?

i think a AWD FB would slay all the competition.... i've wished they had AWD rotaries since i first got into them when i got my 87 TII

so crazy i would like to see it done

what tranny and transfer case are you planning on? you know the mazda mpv's with the 3.0l engines tranny will bolt right up to a rotary. mounting it will be a different thing though. actually the tranny's ( at least the automatics) are the same as the 3rd gens.

on f'd up Double Post lol

I remember a friend telling me about seeing this done once ill ask him about it

Awd
 

I would mount the engine transversley. there are a number of Transaxles i could use. I am going to start my research. Any input is encouraged. Will take alot of
planning and research to make it work. Sinse i have spare parts cars i can experiment alot with this. rx7doctor

i know someones done an awd setup on an fc........ it was a pikes peak car in the early 90's... have pics somewhere, just have to find them

I would suggest a subaru awd system and mod it to work with the rotory because its one of the only full time awd with 50/50 to 35/65 were the majority goes to the rear wheels. gen 1 DSM's ( talon, eclipse, lazar 90 -94) might work they are fairly strong good for up and over 400HP. Many of the awd are the oposite like the EVO. Your also look for somthing thast made to run full time 4 wheel not like many 4wds used different gear ratios from frount to back so your only supposed to use them an loose surfaces.

What about the tranny and transfer case from a 4WD mazda truck? I hear the trannies in the mid 80's trucks are basically the same as an RX-7 tranny.

THIS THREAD IS USELESS WITHOUT PICTURES!! :D

Rod Millen used 626 components on his 1985 rally FB that beat up the Audi Quattro's. He also built a FC 20b AWD for Pikes Peak. Pics are included.

The Mazda RE4R01A / R4A-EL Transaxle found in 1993 and up 3.0L Mazda 323, 1989 to 1993 3.0L Mazda MPVs, 1990 to 1993 Mazda B2200, & B2600i 2.6L trucks, and 1993 RX7. It is also found in the Nissan Pathfinders, 300ZX, 240SX vehicles. It is also found in the Infinity J30, M30 and Subaru Legacy Vehicles.

I got your pictures. Does the word MOON mean anything to you? LOL
Thanks guys will start researching. rx7doctor

Yee-haw!

Don't know that it would be possible but the drivetrain from a Subaru RX coupe would be interesting. A) it would let you mount longitudinally B) it has a high and low range C) the car is of similar dimensions reducing fab work and D) it has locking differentials.

my buddy was just telling me yesterday, how he wanted to get a BMW E30 body, and swap over a skyline GTR engine and drivetrain. he made great points, can easily get a front clip from JARCO for $5500, and get the rest for prolly a total of $8000. then with custom fabrication, he could have that thing running for less than a new SRT-4. but yeah, an AWD first gen.....unstoppable.

It would be tight to see but the main reason I love the FB is low weight. AWD is usually heavier and will most likely add weight, but it probably wouldn't be enough to stop it from being a bad ass light car. Good luck.

solution....upgrade engine, brakes and tires. i wouldn't think that adding awd to an fb would totally destroy the handling enough that some upgrades wouldn't fix. i would try to get an older scoobaroo transmission for the swap. and if this swap is accomplished i MUST have a vid of an fb 4 wheel burn out :) !!!!!

In holland an AWD 626 & 323 were available throughout the 80's & early 90's... That also could be a good option.

we had the 323 GTX here... not sure if the 323 GT was also available AWD... i'd think the rear axle wouldn't need to be messed with in an AWD FB, its got a good rear diff if u have the limited slip model... the biggest concern wouldbe the front axle, and i'd imagine with this upgrade you would also basically need an all new front suspension.

323 GTX was AWD the GT's were front. Someone mentioned using a Subaru tranny because htey have a rwd bias, thats only true on the STi's. otherwise they are 50/50. Subaru tranny would move the engine forward of the axle tho. I think there's already an adapter for Audi Quattro trannies for the rotary.

Hey I found one that might work its the awd for the Ford areostar it uses a turque clutch system so when the rear wheels spin the clutch grabs and locks the frounts in it farly tough and can be found in the junk yark for a few hundred complete.

why re-invent the wheel here? Copy what Rod Millen did part for part, he kicked some serious butt with that car and it was reliable from what i recall. It worked for racing so it should work for you....

For the record,Millens 1983 conversion added only 100lbs,on the tube chassis 300hp car.It used 626 front suspension and drivetrain and a special adaptor to fit a transfer case made by Weismanns Transmission Research and Developement,to the tranny.Sounds pricey,but it was light and had a higher top speed than Buffum's Audi.
Millen had two wins that year,but lost the championship every year (usually to Buffum) until he won in 1988................in a 323GTX.

I'm interested in it for my 78-79 sa22c rx7 and add an air shifter. Would be really nice

i want to try that in real life, just walk up to someone and continue a conversation from sixteen years ago

Not mine, but I'm just here to feed the necromancers.

Series 3 4wd rx7
 

I’ve heard and seen a few good ideas on the thread, I’ve completed the conversion in a dirt circuit car tight squeeze and a lot of custom bits but easy enough

The series 3 is running 13b turbo EP and a 4wd not awd , running full transfer case etc. was running rear wheel drive prior in my class but to hard against my competition on clay surface so I went 4wd, is a rocket for what it is

Super Cool! What transmission, transfer case, and front differential did you use? I would definitely be interested in hearing more about your build.

Bit overkill but fullybuilt th350, 3200 stall, suburban transfer, wrx diff in the front series 3 rear with Cusco lsd both running 3.9, 50/50 drive front and back

As stated by others a Subie AWD drive-train would be the easiest, trans adapter plates already exist to drop rotaries into subies...

No doubt but motor sits way north of crossmember , wanted to keep my centre of gravity similar to keep the handling of FB 50/50👌

Have also performed the setup you mentioned but as I mentioned was a pig and a lot of mods to get it to not understeer , but was in a escort and saying that the engine would be in the nose cone of rx7
