ok yea i just wanted a honest opinion not just reading what people are trying to sell me, i don't really think motor size matters much these days i got 400hp easy from a sr20det, nissan 4 cyl, i don't do the hands on work really that's what mechanically minded friends are for but yea back to the bm i like the 4 cyl and i really think that it's worthy of boost so thanks anyway.
