i recnetly turbod. blew my head gasket im looking at getting the vac upgraded .14 to lower compression a little 2.
i think a turbos more unique and fun. neither are good ideas for a budget and all in all both will come in at the same unless ur doing the labor urself. if ur doing the work on ur own a turbo is cheaper just part wise.
s50 will force not only and engine swap but tranny, clutch, brakes, and suspension
u cant make a 4 banger fast for cheap sad fact of the matter.
