sold the FD...kept the FB
since you would be adding weight, the car would probably be slower. It would be quicker around a turn where traction is an issue, but thats about it. Don't get me wrong...making a FB 4wd would be hella cool, but it's just not so practical on an average budget...especialy to race it. I think a FB would be more competitive in a 2wd open class...maybe in the CRS (california rally series). If you built it 4wd, you'd have to run in the 4wd open, which would be extremely competitive. A friend and I have been toying around with the idea to build one, but have never gotten anything off the ground.
just my 2 cents

4x4 will make a massive difference on loose surfaces and in wet/muddy conditions ... however I think a RWD rx7 would be quicker (if it had the same power) on a dry tarmac stage. (hence why the group B 7's did well on some events even tho' they are only rwd)

hey Mike! We have been looking for you! Don't you like the European forum anymore? You haven't posted for ages!!! Turboren even asked for you (in our hijack thread I believe) and some people suggested we'd hijack the UK forum untill you came back!!!

weren't the earlier (1st Gen) Rx7's based on the 626 floorplan/layout....
if they were front wheel drive then it would make sense why you would use the front drive components of the 6
wouldnt it??

wouldnt it be easier just making the RX 2x2wd???
two gearboxes, twin engine :)))
2.6L of fuel consuming fun-ness??
what do you guys think??
im thinking it'd probably be easier than 4wd.... not that im going to do it
i dont imagine it would be legal either

lol.. how in the HELL would it be easier to make a twin engine RX-7 as opposed to 4wd? what would you mate the second engine and tranny to? the only way that would be easy, would be if the RX-7 was a fwd, but in that case, it would lose a lot of fun factor.

Yeah, the twin engine cars cars people come up with are almost always based off of FWD cars, because you can just drop an engine and transmission in the trunk. To make a twin engine car from a RWD platform, you would need to redesign the front transmission to drive the front wheels, and then set up the second engine for the back wheels.
But it would be cooler to have 4WD and two engines then 4WD and one engine...

yeah
but even though 2 engines would be sweet.... add quite a few Kg/Lb and take off a crapload of storage space....
you could always remove the passenger seat and put the spare there

Everything has been tried before. The VW type 164 was a 1941 twin engine 4wd concept. To make it more interesting it had twin steering with a second steering wheel so you could steer the back wheels if you ever got bogged and had to drive out backwards!
Lets be honest, Mazda never produced a decent rally car even in prototype form. The RX-7 just never had the potential characteristics, the 4wd prototype was not a success and there never was talk of production. Attempts to produce a rally model of the 323 failed, it just was not competitive. Having driven the 4wd rally version all I can say is I was pleased to get out alive. The handling and weight balance was all wrong and without a completely new 323 design it would never be a serious contender. That was not a commercial option. In contrast Suburu got it right and have gone from strength to strength.
The Mini-Cooper was a very successful rally car in its era, but attempts to produce a 4wd failed. A few were factory built on the Mini-Moke platform which were fun to drive, especially in the 1275S bored out to 1500cc autocross configuration. But there were never going to be a competitive or commercial success. Attempts tp produce a military airbourne version to replace the jeep did not get government approval.
The moral is just because you have a great 2wd is no valid reason to exotpect a 4wd version to work.

Hmmm, there also was a twin engined Citroën 2CV (and even a twin engined one with two front ends!) and DAF had a Paris Dakar twin engined race truck (two headed aswell!)
The Mazda 323 didn't do bad in Belgium and Europe though. But indeed, a good 2WD doesn't mean a good 4wd can be build out of it.
