Quattro derivatives

[hamski]

It's not really RS246 subject matter, but does anyone understand the difference between the old quattro engines? I've seen WR, UR and RR cars for sale, but haven't a clue as to which is most suitable.

[Greg_S]

depends on what sort of engine you want in it for a start.

10V or 20V is first question

WR = 10 valve, solid valve lifters, some would say easier to tune 50/50 torque split, lockable center and rear diff.

MB = 10 valve hydraulic lifters, water cooled turbo, anti stall device, torque sensing diff 70/30 30/70 split lockable rear up to 15mph etc not as easy to raise boost! K jetronic fuel injection.

RR = last of the line 20v motor motronic management etc.

And i love them all! [img]images/graemlins/kissmyrings.gif[/img]
