Does ignition(exJacobs Ice Pack) make that big a difference? I'm in the process of doing a motor build up. Trying to add every bolt on but want to get the most bang for my buck. Header is on it's way from the group buy, Catco hi-flow cat already sitting in our house, 2.25" stainless piping coming too as soon as the header gets here. Already have a Tsudo performance muffler on. UR pulley was ordered from Courtesy and MSD fuel pressure regulator also from Summit. Car currently has NGK plugs,Ractive 9mm wires, and Ractive WAI. Shorty shifter as well. The next mod I was looking at is ignition, but is it worth it, cuz it's like $300-$400? I'm not looking to go CAI right now either. If anything I will wait for Alex's to come out. But my preference is WAI right now.I'm not looking to go NOS just yet. Want to try to go all motor first. Pistons may come at some time, but it will be expensive due to re-machining the motor. Thoughts? Feedback? Suggestions?
