I am runnin a 00 b18c5 with about 11.5:1 compression, skunk stage 2 came fully worked over head and a toda header. i have it mated with a stock exhaust till my mugen twin loop gets here from japan, it just feels like it backin up pressure in the intake and i can figure out where it is smokin from under the hood, the coolant temp is fine and everything else seems to be fine, i just cant figure out whats wrong
