is the wrist pin height of the ctr piston compatible with a gsr rod on an ls crank? in a b16, the only modification necessary is to machine the wrist pin side of the rod in order to fit the rod in the piston. it would make sense that the wrist pin is in the same spot as a B16 piston, because they work in a B16 with no clearance issues. i have a friend using B16 pistons in his ls vtec, but it does look like the compression height (in the hole) was closer to zero compared to his B16.
