What would it take to make a TII AWD?
I know, no flaming please, but I was wondering if this would be possible... This is just a crazy idea I was thinking for a kit car and I was wondering the feasibility of this plan. (BTW, i was thinking about this before that 4WD scout with a rx-7 body came out)... Anyway, the parts required are the differentials and transfer case. We already have a rear LSD which is stock on the T2s, so all I would need would be a front differential (do fc's have these or do just AWDs have them?) and a transfer case. The obvious choice would be to go to a junkyard and find a junkyard Subaru which I could use... if I did this, I would try to get the front diff and transfer case to bolt right up with the rear drive shaft... if I could do this, then it would be possible to rig up an AWD system on a FC... comments?

subarus don't have transfer cases, but Mazda Type R transmissions do. they are for 4WD however, but this is the piece that millen used.

If you want to keep it in the family, the 323 GTX was AWD, but they are rare and expensive.
There are plenty of cars out there besides Subarus that have AWD systems. If you were serious about this youd have to do some research into which would work best.
BMW 325ix
VW Passat Syncro
Quattro systems from almost any Audi
To be honest I'd stay away from Subaru as thir AWD system is 90% FWD, and AWD when needed - whereas the BMW is RWD all the time, and AWD when needed.

in the Subarus, the front diff is one piece with the transmission. I know, because I had one 
The front axles come out of the tranny...which means the engine has to be completely in front of the front wheels, which means it's not going to happen in an RX7.
Good luck, though. But it would be difficult with a longitudinally mounted engine which is directly over, and just behind, the front axles.

yeah, are you over there, also? I'm JGard over there...and yes, I waste many hours in OT hehe
I sold my RS (it was a 2000) about a year ago. Miss that car...but I've always liked the FC's more

It feels so good to be right.

so what do you all think about taking a 323 transfer case, differntials, and even the axles, brakes and attaching them to a FC engine and tranny... but about the axles and brakes, couldn't i still use the fc ones?

It's on page 82 if you have the book close by.

the GTX is not a good idea unless you have 2x the price of the car for spare trannies.
Jgard, i'm Projekt (surprise) on nasioc.

the tranny is also made of glass.

hmm. I don't think it would be worth the effort.. and if you are here asking how to do it, I'm guessing you don't have the necessary skills to complete the project. No offense meant, I just mean that it would probably be better to buy an AWD car and be done with it. You could swap a rotary into an AWD car though. That'd be easier than what you're thinking about doing.

1) remember that although i said that this was hypothetical... i was considering it if it could be done cheap... now since it has been pretty much decided that it cannot be done, its more for purposes of discussion...
2)would a rx-7 t2 engine and tranny bolt onto a 323gtx? which would then have the rotary power and also be AWD...
thanks guys, i love discussions like this

However, the amount that you would have to change to integrate a subaru drivetrain into an FC would be prohibitive....however, what about dropping a 13BT in an Impreza? Food for thought.

I was under the assumption that the AWD systems in old Subarus (ones old enough to be in a junkyard as he said at the top) were primarily FWD. I knew that their newer models - most notably the Impreza had a more even distribution of drive but I didn't know there was a difference in auto - versus manual. Were Subaru's always 50/50 in their 5spd AWD's? If so - I stand corrected. I've only owned 2WD ones.....
