and what do u drive some busted up honda civic with a lsvtec swap, ha, some on buddie these are straight race engines 140:1 compression 10psi, but i'll tell u a lil secrect, psi dont mean to much with out boost ratio, surge flow ect. u cant tell a guy what he cant do if he done it more than once, dont judge someone if u dont know them, but i may send u a dyno sheet and the stats of this motor, i really dont care if u dont belive me or not, i'll sit in the driver seat and u can sit on the couch and watch me do the job
