Hi everyone!
I need some help with making a decision on a straight through exhaust size for my FWD mazda 323. Im going to buy an engine 1.8L DOHC NASP 135ps @ 7000rpm and 16.0 kg*m (156.91 N*m) / 4500 rpm ..to put in my car. but before i do.. Im going to get/grind a fast road cam with a duration of 170-175 degrees... and also get some forged pistons and some forged conrods... and i need to make a 31/32'' manifold i think 4-1 or 2-2??.and a straight through exhaust... but first i need to know if i should get a 2''...2.25''.. or 2.5'' straight through.... keep in mind its Naturally aspirated.. or if these sizes I've mentioned are not what you think i should go with..please tell me! =D
and was wondering what kind of manifold as well...
Thanks so much for reading!! Any Opinions will be much appreciated!
