Its not really neccessary to bore the block out when u have FI. All i can say is rebuild the motor to higher compression (10:5) or lower compression(9:5) and resleeve with either darton or my favorite...eagle golden sleeves. I'd get wiseco pistons. If you wanna get cheap then get srp pistons. Notice when i said higher compression. It'll make more power but u need PROPER TUNING. You might not boost as high but u'll make more power and it'll be faster. Less lag also! Theres so many ways of makin this happen. U just gotta research. Try
