I don't think is the bore kit...I think is the piston you choose..But I'm not sure..I'm retarded..

if you have a kit with a 12:1 piston you can run pump if your carb is jwtted properly. i run a 13.5:1 and i have to use a 50/50 mix of race and pump. many kits give you the option of which compression you want

My buddy has the Toshi 450 kit on his Z with a 13:1 piston and he keeps up with us all day long. His quad rips!
