I started with i, e & h, pulley's, fr, fpr and then I got the Zex dry kit. I like it but I would much rather be turbo'd. So that's why I am looking to sell the kit.
Well in my opinion building up is always better to start w/ so then your car will be ready for the big stuff (i.e. nitrous, turbo, sc, & na). If you decide to build up first then I would get the throttle body to go with your i & im.
$300 for the Zex kit is pretty good (does that $300 include the purge kit?) Since you are getting the Zex for so cheap & if you want quick hp then go for the nitrous; if the Zex kit doesn't have a bottle warmer w/ it then I advise you to get one so the bottle will be at/around 900psi (a new Zex warmer is under $150.)
