ok... after reading Aug. Super Street mag, there was a whole section on turbos... so as i got to reading it... i started listed the necessary mods to build up my sohc engine. but before that... i would like to know if anyone can tell me what is the compression ratio for the sohc head (d16y... something, i forgot )? also, what does it mean when they refer to "cam grind"? well, there are a lots of stuff i don't know about turbos... and since i am thinking about doing it... i figure where better place to go to find the answers then the H-A, or HAN. :naughty:
