Okay well im still at the stage of contimplating whether to go a b16a or a b18c7 engine for my eg. My power goals to gain 140-160 kw atm. I realised that the b18c7 has more than the capabilities to do that whacked on with a nice turbo (t28 muahahahahah), but the down the side of the b18 was the high compression.. and the more Munnies being spent on it. But yer just want your guys 5 cents on which way to go =]
