You can use all the torque you can get lugging around that 3500lb car... I consider my s14 heavy and it weighs in at about 2700lbs... if you ever race chris maybe I'll waste a gallon on my barney sause showing you what you're missing out on, and yup your parts are upgrades to our cars, and we nake better use out of them in our lighter cars. Z32 tranny is the next upgrade I'll be taking from your cars. Matt was simply trying to help you listing what it would take to free up some power and get you moving, I don't see why people are stubborn about oh I want to make xxx stupid amounts of power on stock cams, stock this, cams are an awesome upgrade. 300zx great parts, shitty to service and quite heavy, hell your car is so baller it comes with headlight adjustment tools in the hatch in a special box.
