i was looking of turboing my rs1800 engine .. but thm though agensed it .. if you want a good reliable turbo power go zvh or just stick with n/a and put throttle bodies and leave the engine ... coz tbh the cams are the same size if not bigger thn the 2.0l cams , do a lil bit of porting and jobs a good one but yeah turbo al the way once you have have some boost you never go back !!:L lol only resin im going n/a is i cant afford to build a zvh and also its my first car :L
