crossflow 8V's will turbo easy loads of room round it none of the parts are all that spectial or complex so you'd be abel to do all the pipework without much bother.
as said if you want to know about boosting motors read vortex tho a few differances worth noteing between here and there, the ABA is 9:1 compression 8valves here are generaly 10:1 but the petrol here is quite alot better.
superchargers are brutal when it comes to torque, get a nice big eaton and halt the time your actualy holding it back trying to stop things twisting themselves to death. much more responsive than turbos, turbos tend to make bigger bhp numbers for less money it allways used to be the case that big turbo were crap when it came to drivablity but the modern ones are amazing compared to there predicessors. main problem is when bolting a big SC to the frount of a vw 8,16 or 20v is the frount pully as they can absorb a LOT of power eaton M112 needs something like 90 HP whene it spinning its fastest and blowing its hardest vw frount pully wont do that
