i had this idea today and had a look under the car it looks doable but$$$

p.s please dont say crap like dont bother its JUST and idea so please keep the comments on topic

You have the engine/gearbox back to front so you have to make yourself some new engine mounts too. A fwd --> rwd conversion is classed as an individually constructed vehicle by the RTA so good luck getting it engineered too. Just not feasible.

in my design i keep the engine/gearbox the same way and just "bend" the driveshafts around the engine. at this idea stage i hadnt thought bout engineering cert. btw im in vic so would that make a difference to the class ie individually constructed vehicle.

thanks for the reply

The main issue with this set up is that with all of the direction changes for the engines torque that there would be greater losses than if the engine was turned 90 degrees and just drove straight to a rear diff. Other than that, it could work.

with this way the engine mounts would not have to be refabricated. the firewall would also not have to be altered. i dont know if the rear end can take a diff though also the fuel tank needs to be altered to fit the drive shaft. but apart from that i dont see a prob with it?

The AWD Magnas have a rear diff...

Do 2nd gen engines run west east (opposite to 3rd gen)?

yep they mirror the 3rd gens;
putting a twin turbo 6g72 with the awd gearbox would be the go but you'd have to have the tunnel customised hot rod style. The 2nd gen shaped diamante's ran the awd its not feasable in any terms since you can import a diamante....

not running awd just rwd so the gearbox is still next to the engin and the drivetrain goes round the engine to the rear diff in where the exhaust normally is. the exhuast would have to be moved (to where i dont know). but how much strengthening would the rear suspension/wheels need to take power. could it be as simple as a diff in and thats it surely not?

Food for thought:
Get an AWD magna/diamante and modify it so that the front driveshaft isn't connected.
Wouldn't that be the easiest way? Or somehow add the AWD drivetrain.

the awd only came in auto. and i think the transfer case went into the tranny tunnel (not sure though) thats why the awd setup cannot be put directly into the 3rd gens for example because of tranny tunnel issues also known as floor pan. this way will just have the drive shafts down the middle of the car.

oh and whilst talking to my dad in rwd without independant rear suspension ie live axle the suspention is the only thing that supports the diff. so with a modified tortion bar and a rear strut brace it "should" be strong enough.


ps keep up the good work of helping my idea along thanks

You can fit the 5 speed manual (or 6 speed) from the EVO VI/VII - probably need to modify the bellhousing, but considering the work that would be need to done to fit an AWD drivetrain, this is the least of your worries.

Why RWD???

Also, the rear diff of the AWD magna only recieves 50% of the torque of the engine - disconnect the front driveshafts, and you have a viscous coupling passing 100% of the torque. Scary.

rwd for snakeys and a bit of drifting. plus awd was only auto and cant bolt on the manual tranny. plus as you said it needs to alter the bell housing. that needs an engineering cert. i dont know if my way would need it, would it?

Ummm i think either way you're going to need an engineers certificate.

Sounds like a waste of money to me. With the amount of money you would spend doing it, you could pick yourself up a second car for drift purposes.... Just get a 180sx and be done with it.


Damn I want a 180....

It'll be allot easier to get an engineers ceretificate for a manual conversion on an AWD Magna then a custom RWD conversion. The Manual convertion would use an existing trasmission, but would require some modification to fit up.


Either way as stated, you idea of trasfering the torque through so many 90 degree bends will sap a whole heap of power by the time it reached the rear wheels (you'd be better off with a simpe chain drive setup to transfere power to the rear using the engine in it's standard poistion, just good luck with finting a chain strong enough).:P

Yeah I can't imagine the rear diff lasting too long if it has to cope with 100% of the torque/power:shock:

Question is would you spend $10,000 or how ever much it would cost to convert a 1992 4 cylinder Magna from FWD to RWD? It would probably be slower than the FWD version since it would lose more power to the wheels than the FWD version and wheelspin isn't a problem in a 4 cylinder TR to justify requiring RWD. I think you're crazy for even thinking of doing this. Having said that. IF you want to do this, I'd at least do it on a V6 3rd gen.

The evo VII gearbox is exactly the same as the invecs II tranny out of the awd third gens, so might as well just make up an adapter plate, and if u still want a rwd, then you could like someone else said, just remove the front drive shafts, could be a very nice car.

although getting around the yaw control and all that with the evo gearbox could be a slight problem....

Or you could transplant half a VR into a gen1. That would be cool in a scary hybrid kind of way.

i live in victoria near big chadstone shopping centre. does anyone know anyone that could give me a cost on the rwd conversion. that will definetly be the go on whether to do it or not. oh and with tyres with over 85% tread i cant get traction in the wet.

I'll help you with cost, how much is your car worth? multiply that by atleast 10 and you will still be short of the final figure to have it done properly.
I was about to undertake a AWD conversion on my TS, and even with doing a lot of work by myself (i am a mechanic) the bills were looking upwards of 30000, (even though it was going to have a TT 6G72, etc)
To be honest, i would spend more time on considering backing off with the right foot, if you can't get traction in the wet, as any car, no matter what tyre condition is like will do that with full throttle in first, before worrying about a RWD conversion.

im getting spinage with 10% accelerater and ridding the clutch so bad it could be wearing it out. was thinking lsd for the front but wanted to see if rwd COULD be done. lets see then the cost should be round 10~20 thousand. does any one know how much it was for the red third gen with the v8. or know his email so i could contact him

I think you need to buy some decent tyres....

there goodyear gtrs http://www.goodyear.com.au/passenger-tyres.htm and they came on the carSo basically Goodyear's budget tyre. Get some decent rubber.

Even with the current rubber, there is no way your car is losing traction on an easy take off.:doubt:

i wish it wouldnt break traction:doubt: but it does. so i live with it till i get my rims.
