ok so faQ dont give me any results every time i try it. but i have been searching thru old threads so dont nobody yell at me. so i've come to the realization that the n47 is notorious fer cracking, so im pretty sure that will be the case on mine. now fer what i want to kno. i thought i saw somewhere that the n42 block had flattop pistons. true or false? also i measured my intake ports on the E88 and there 34MM, I read that they were 30MM stock and that 33 to 35MM was a good street bore, is this accurate? also assuming that both my cams are stock which would be better the E88 cam or the N47 cam? i have a 64MM TB on the car. How the f@#k could i need that on a n/a motor?
