Met another Zer tonight from here. Bret Dempsey ( LitlElvis ) as he came down to get my stock recirc valves. He has a nice 91 Ztt with the Stillen 18" rims. Anyway he pasted this site on to me on how to do things the ZshZ way,,,lol. Make your own parts and learn about other things such as Dyno numbers, why use 4th gear, how to build intercoolers and so on. Check it out.
