Does anyone know what's involved in converting a Classic Scooby to rear wheel drive? I'm assuming it's not as simple as removing the front drive shafts??

Cars are 2 wheel drive only so it has been done in competition.

Think HDC Subaru nr Hebden Bridge prep it, could be worth contacting them.

talk to these guys... or get searching around on driftworks forums, they might have a thread on their cars somewhere

I suppose why?

Also DCCD maybe?

In short you'll need to lock or remove the centre diff and likely want to remove the front prop and driveshafts.

You can weld the centre differential, its pretty easy. You take the gubbins out of the cylindrical housing and put a ring of weld around where the driveshaft flange bit meets the housing.

The downside is you're putting all of the power through a diff designed to take only half of the power (the rear diff) and you're not removing the weight of the front 4wd gubbins.

You'll pop the rear diff before long I reckon.

The guide I read was done by a guy who wanted to dyno his car on a 2wd dyno so it was only a temporary solution, but he bought a whole spare centre diff to weld up so he could put it back to stock easily. He also said it was extremely tail happy, having been set up for 4wd.

My opinion is, if you want a RWD car, buy a RWD car.

yep, the geometry would need adjustment as it will be set up for 4 wheel drive.

So thats camber and toe at the very least.

Rear diff and drive shafts won't hold for long especially if you run more than standard power.

There is no front prop?

Need to block up the holes in the gearbox/diff housing where the shafts go in, for obvious reasons, if you're removing the driveshafts. And the centre diff will need welded/locked somehow.
Sorry was thinking of a Land Rover.

Its amazingly easy to do, pop the rear prop off, the back of the box off, 20 mins on a ramp, whip the diff/unit out, weld it up. Pop the front drive shafts out & plug the holes.

Hey presto rwd, they are good fun but you will blow the rear diff up quickly if your hard with it.

Theres a few threads on driftworks on how to do it

cheers everyone! Not worried about it being too tail happy, thats the idea, I'm wanting a drift car and was thinking of doing something a bit different to the usual 200sx/E36, plus there are plenty of cheep Scooby's about. Would welding the rear diff as well make it stronger so it can take more abuse (as well as the obvious drifting advantages it would bring)?

No offense, but is an Impreza really all that original or different for drifting or the Jap tuning scene as drifting largely seems to be centered around?

I'd have thought if you wanted something different a Rover SD1 V8, P6 or a Jag XJ40 would be way way more original.

As already mentioned above, the problem is likely to be that the rear diff and shafts are engineered to live with a 50% (ish) share of upto 300bhp (ish), and therefore sending all of the power to the rear is doubling the amount of power the car was meant to deal with instantly .... and that's before you thing about tuning.

I think that your concept is brilliant, and an Impreza would make a great looking drift car compared to the more common Nissan / Toyota and BMW offerings, especially with a barely silenced flat four blaring away. Whilst it may sound like a lot of work, however, you could overcome your strength issues by mating the subaru motor to a more proven rear drive drivetrain. All manner of conversion adaptor plates and systems are available in the US for conversions like this. This does blow the budget a bit though ....... maybe a subaru welded centre diff and a custom prop and shafts allowing the fitment of a Nissan / Cossie / E36 M3 diff would be a good compromise????

Check its all designed to turn in the same direction though wink Some manufacturers like to be silly and run their drivetrains the "wrong" way.

why not try a mustang for drifting. don't recall seeing many of them on the circuit.

i would expect the scooby could be done, but you will have to strengthen it a bit to cope with all the power through the rear all the time.

other than that, get a skyline gtst, LSD as standard so no need to weld, instant drift hero with no mods.

You could just get an import Imprezza Type R or RA instead which already comes with an adjustable centre diff instead. This can be set to send 75% of power to the rear from a dial in the car which makes the car very tail happy and you don't have worry about welding diffs and messing about with suspension settings etc.
