In theory this could be acheived by simply removing the front driveshafts and sealing the holes in the gearbox?

Would this in turn reduce the massive transmission losses the impreza is plagued with? Or simply produce an underpowered, gripless bag of sh1te?

What about the centre diff and transfere box....get a 2wd coss box as they are cheap as and fit that....

bit gripless as 4.4 diff is very wheel spin city

Is it as plagued by transmission loss as suggested by the environment of a rolling road where it is strapped down and has a double contact patch per tyre?

Accelerometer testing suggests far more impressive power at wheels than is achieved on a chassis dyno... if a classic UK Impreza for example only has 120-130 at the wheels as Powerstation typically gets (which rates the car at manufacturer's quoted output for flywheel), then how does it manage a typical 9 second 60-100 when it weighs over 1300 kg with a driver and fuel? That performance from less than 100 WHP/ton?

How about a Type R with adjustable centre diff?

You would need to lock the centre diff somehow to allow the power to be transmitted to the rear wheels only. Then you have the problem of a relatively small diff and driveshafts coping with the full power output, not to mention how much slower the 0-60 time would be.

Don't think the DCCD fully locks when in the "Lock" position John. Even if it did, I wouldn't fancy its longevity much if asked to do this job. It's bad enough driving a type R with a broken front driveshaft and the diff on "Lock"...

What "massive" transmission losses?

It'd produce a barely mobile lump that would probably only crawl a couple of miles before the centre diff sh*t itself.

You can convert the impreza to RWD. It will involve welding up/ replacing the centre diff unit and sealing the gearbox sans driveshafts. Cusco, amongst others, ran RWD impreza's in japanese touring car/GT type championships etc... IIRC, RWD is a mandatory requirement in some of those championships, hence all the RWD only skylines that appear in GT3.

I recon RWD would be a hoot, but not as quick and stable as AWD... and the scooby weight distribution isn't really perfect for RWD. A DCCD diff is much more fun than to regular 50:50 centre diff.

you wouldnt need to seal driveshafts.. as there are stubs that fill the holes... front wheel bearings would need the splined bit of the shaft through still..

get a fooked centre diff and peg it / weld it up..

I would look to remove the front differential unit anyways, it would just be dead weight. Then the axle holes could be plated over.

I like the Cossie route!
I hillclimb against a tweeked 2WD 340 bhp Cossie, and I can catch him on road tyres easy despite the power loss of my STi V3.
Ever tried changing gear quickly in a Cossie, STI boxes are MUCH better!
Hard to beat the Scooby 4x4, even with less power on the ground...
BUT, that front box etc weighs a lot- you have an interesting idea.
