I need help w/ cams

08-30-2007, 06:30 PM
i have a '99 zx2 w/ the dohc ztech engine and i was wanting to put larger cams in. I have always heard when you put a larger cam in your car you loose vacuum pressure, which could affect the brake booster making it hard to press the pedal and to stop. is this true? secondly if i were to put a larger cam in would i have to get the same size cam for the exhaust as the intake or could i get by w/ a smaller cam (or even the stock one) for the exhaust?

You will not loose enough vacuum to notice. If you want more in you have to get more out. Replace both cams.
