Leading upto wanting to do a Zex kit whats a good step after I/H/E, I don't want to put the Zex on quite yet so I have a seperate account savin up what I need all the guages etc.. that comes with it. Are the AEM Cam gears good for the use in combo with NOS? What other things should be done, I don't want to do pulleys. The goal is high 14s to low 15s in an AUTOMATIC 4 DOOR civic. Its a 1999. Can it be done?

High 14's, low 15's will be tough. The cam gears will help eventually but not right off the bat.
I believe I saw an article on putting an EX manifold on a DX engine. I might be wrong though. I'll look around for it again.

A good step after I/H/E is suspension if its not already done. Also look into weight reduction. For every 100lbs you can gut out, you will shave about .1 off your 1/4.
