first of all i searched but im still confused. I want a single turbo i know the t-88 and hks51 something are not good even though they make incredible top end power they suck through out the power band. the apexi, xs and t-78 are all good. Know what about the gt35/40 that thing looks sick it can make up to 700hp but how good is its spool up. Also is the bnr stage 2 upgrade worth it. And is it better to have them sequential or parallel. Also what kind of porting would i need on my engine and whats the average cost of porting your car.
