I think you might need a second 'too hard' basket to put this in.

It'd be almost impossible to get registered. Too many mods. But maybe it's possible.

The front end would be the tricky bit, and by using a GTiR front end to get you the varous 4WD front bit would make it easier, but It would involve shortening halfshafts and
changing suspenstion parts so it all fits under the guards.

So all the original 1000 suspension would be removed.

No doubt it would involve putting in a much larger tunnel, and I don't think a 4wd engine + gearbox would fit in a little ol' 1000 engine bay.

The chassis may not cope and might twist out of shape. That would make all of your work wothless as the wheel alignment changes everytime you give it some throttle. You wouldn't
need a strut brace..more like an 'entire-chassis' brace.

Could be fun...would be expensive, who knows.
