So ive seen people talking about making the 3rd gen an awd and I agree that the rotary does not have enough torque to power all 4 wheels no offence. But I have a v8 rx7 that has a **** ton of torque to spare and was wondering if it would be just as hard/pointless to attempt this with a v8 rx7??? what do you guys think??

redrider13

I think you're crazy.

lol well it might be a compliment?? no WRX could keep close to an AWD V8 rx7 haha

It would be easier to do with a rotary because they can sit further up in the engine bay. You would have to use a Subaru style transmission that has a rear wheel drive layout. But is has to be mounted far up so the front axles could reach the hubs.

Also, a rotary would have no problem turning an AWD drivetrain. How much torque do you think an Impreza L makes?

AWD only helps you off the line. Nothing that a proper rwd setup can't accomplish. There are plenty of high hp subarus that go V8 hunting all of time.

Oh yeah ive seen wrx's beat camaro's all the time im just thinking about AWD being able to pull and push my car around corners as well as improove my 0-60 time

ronbros3

it would make a great combination, but what kind of AWD drivtrain can take V8 torque?

Rod Millen used to rally a AWD 13B P-Port back in the 80's in a FC..


i think they used components off a Mazda 323 GT-X

The one in my S4 does a pretty good job.

my dream has always been to build a All wheel drive mid or rear engine 20B turbo time attack machine!!.... One day I will embark.... Now where to find sponsors... haha

I have pictures of the millen 7, including one or two of the naked drivetrain. I'll post them when i get home.

So finding a AWD differential that will fit in the already limited space that will handle the ls6 torque =/

The Trailblazer SS has the differential built into the engine oil pan.

Wonder if Changing the transmission from my t56 6speed to some other trans maybe an AWD chevy trans my biggest issue I think is the transfer case and its size fitting in the trans tunnel.

The 32, 33, & 34 generation GT-Rs do this. There's a reason that a maximum of 50% of the torque could be directed to the front of the car, and aftermarket controller boxes delayed that transfer until just before the rears hooked.

The lsx swap may not upset the balance of the car "much" but I think a differential, powered hubs, and another driveshaft might.

the skyline gtr motors have the transfer case attatched to the motor, directly underneath, could be built into the oil pan much like the trailblazer ss mentioned above, if you could make a K member to bolt that in, that would be pretty sick having an rb26 drivetrain with awd

The 6MT transmission from an STi would have no problem handling the torque of an LS1. Subaru designed STi's to have great low end power, hence good torque. Some even have higher tq numbers than hp numbers. You can tell just by looking at a 6mt it is very durable. I guess that is why they cost $3000 used.Plus the transfer case in intergrated into the transmission, so no clearance issues.

haha looks like nissanconvert beat me to the skyline idea barely

bcool

Think about how far up the stub shafts are. The motor would be hanging out of the front bumper. It would have to be a skyline type AWD setup.

rodumslayer1

anyone know how close the trailblazer setup is to the skyline setup?? can anyone post pictures of the drivetrain of these AWD cars ive been looking everywhere

You would have to pull the engine way into the cabin of the car to fit it; the trailblazer setup would need it WAY back (1' into the interior or more) and height would probably be a concern. Custom hubs, steering, etc. is a whole different set of issues. Not to mention vehicle balance, etc.

Interesting thought concept but not viable in reality.

Now, a tube chassis or something with a different layout and sure, it might be possible. The RX7 just isn't the best option for it.

rodumslayer1

as my dad always says... "anythings possible... how much money you got??" haha one day this dream will become a reality. need more suggestions tho..

I am referring to a 13b not a lsx. The OP asked if there would be a difference between trying to convert a rotary and a v8. I think a 13b would be easier just because of the size. There is enough room to fit a boxer engine in front of a 6mt. A rotary engine is shorter. RX7s have longer front ends, enough to fit V mount intercoolers. Seems to me it might fit. I have both a 6mt transmission not in a car, a spare rotary, and a FD in my yard. I am going to measure tomorrow for the fun of it.

So, not worried about reality eh?

This build isn't happening. Feel free to keep pretending though.

GM AWD layout:



That's not going to come close to clearing your hood; you need the engine 6-8" higher than it sits in a normal swap. The only option is the move the engine into the interior and extend the front driveshaft and place the diff where the engine would normally be. But hey, what do I know.

habu2

fixed it for ya... and we're talking TARP-sized money here.
