just a quickie!!
whats the ideal diameter for a n/a 2l 8v with slight mods and poss supercharger in the future.
i was thinking 2.25 - 2.5 , the other things is ive heard the 8v is robbed of 5bhp from its european cousins due to having a smaller exhaust tunnel than the 16v (on which the european 8v are based)
so if thats correct could a 16v down-pipe be used on an modified 8v system???
