stay oem as much as possible, i dont recomend running hondata on n/a aplication! start with 1.8 liter bottom end, dont fuss with 1.6 unless you like no tourqe, also if you do decide to stay 1.6, mill head and use jdm p30 pistons as in they are lighter and not much less compression then ctr pistons, also ctr slugs will cut things close with valve piston clearence if you decide to waste money on big cams! good luck, eric
