You MAY want to rethink your position on the Chinese turbo's. I have had great luck using them, and Corky Bell (BEGI) engineering, turbo kit Grandmaster, sells and recommends them as well. He (if unfamiliar with him) started /owned Cartech back in the 1980's and designed very good and successful turbo kits for CRX, Miata, BMW, and MANY others! Also, my research has NOT found ANY Chinese 4d55/56t knock offs. In fact, the used engines I was quoted were actually Japanese pullouts (probably mostly except fro some wrecked vehicles), and were therefore priced higher than buying direct from Japanese dismantlers. I sure wish I could buy one of these engines TODAY...been looking for used ones all morning with NO LUCK!! Arrgh! My 4g 64 needs a head, and I'd RATHER just swap one of these in instead...
