DO NOT BUY TURBO FROM EBAY.. you never know the quality of the turbo itself. how bad it is. damage. etx whatever i dont give a shit what the description says .. always have it professionally built to suit your engine air flow.
basically i knew if could cflow the power i wanted, the exhaust AR was high, but i know this can be replaced. anyone know where to get one?. might make for a nice setup running twins on the 7m. but i'd rather keep it simple.
