any place that sells lanve evo VI and up engines
good luck its gonna cost alot

in other words get somthin that has more room to work with as far as swaps and parts to
ie older mirage .. the american 4g63 basically bolts straight in

get somthin that has a good aftermarket to support it

otherwise the only way ur gonna get fast would be putting alot of money into ur car ie custom turbo kit

just what i think but in the end drive what you like
