Ahhh i dont know why i just assumed the ITR uses the same cams as b16 :doh:

i read on another post someone saying that around 9:1 is a really good compression ratio for boosting, is that right?
So if a b18 with ls crank and rods has a ratio of 9.8:1 wouldnt i want a thicker head gasket to try to get it down a little more? Is there a disadvantage to this?

Oh yeah, would a 97 gsr have an OBD-II block?

sorry for all the questions......
