In your guys opinions, what kind of longevity could one expect out of these motors with bigger superchargers? I recently purchased a 03 10th with a KB 2.8lc tuned for e85. Car makes 730rwhp and 670rwtq. Pulls super hard and runs about 25psi. This is a lot of power and boost. I know these cars are for fun but I do want the motor to last awhile. I am very religious about maintaining stuff. Keep in mind I do not beat on this car non stop. Goes out for cruises once every week or every other week and gets floored maybe once a drive thru a gear or two. It has the head cooling mod and supporting mods for the power. It was compression and leak down tested and everything was great. Should I tune down a little or just keep it how she is and treat her right? Just want something to last me a good amount of time. Thanks for any opinions!!
