well most of the b18c2 conversions with eveything i have seen on here lately on this site have been 2gs and under.
even at the honda wreckers behind gpc a b18c2 halfcut goes for 2gs and thats a wreckers.
a b18cr motor goes for between 2000 to 2700,i would never pay 2.5k for a standard b18c2 just for the motor no way
