80/90 quattro transplant 10v turbo

[moggies]

Can anyone help regarding fitting a 200 turbo engine into a b2 90 quattro (1985). Has anyone done this?
As the brake master cylinder is on the drivers side in a 90, will it be in the way of the turbo/manifold etc? I have seen a couple of cars for sale and now I cant decide what to go for. A 90 and take the risk, or an 80 where the master cylinder is on the other side.
As both of these cars need a bottomless wallet to get them back on the road and with the intended transplant for one of them, I don't want to waste any of my short funds buying the wrong one, if I buy either of them. Thanks
