i got a 2000 si head and a GSR complete bottom end. i know they will just mate right together but i was concerned about power ratings and compression. i heard this will drastically lower the compression but then i heard it will raise it because it changes the deck height. has anyone ever done this and do you have any input you could give me. if you have, any idea what kind of power it puts down compared to a regular B16 and a regular GSR?
