The heads and the intake manifold, AND the phenolic spacers still have yet to be installed. I am going to install them all at the same time. I am guessing I should be able to get that done soon hopefully. I've been putting it off! But I know that it will make a big difference, the Heads, Phenolic Spacer, and Intake Manifold together should add another 30hp or so! So I should be cruising to the tune of about 180 hp, and 200tq at the flywheel after those are installed. This is just a conservative estimate, it may possibly end up higher. I still have ignition system upgrades, CHIP, Underdrive pulley, remove AC, headers, and all kinds of other crap that I can do. I'm hoping to reach at least 225hp before I give up on this car.
So is the warranty on your car keeping you from modifying it too much? I think you are basically limited to ignition, chip, intake, exhaust. Not sure if you could do internal engine work.. peace out!
