Your car should be going alot faster. Bcisme's car with 4.10,jlt intake,steeds pulleys and a axle back went 12.8@106 on nitto 555. With a 1.9 60 so your car with the mods should get down mid to low 12's
your right, I think they will too. Im not too worried about a loss if there is one. Even if I have lost a little, it will be a great supporting mod for when I make the jump to a centri blower, and it looks damn good under the hood too!
