I just recently blew my motor from Nitrous use and I am in the process of rebuilding. I decided that since I am gonna rebuild that I will go ahead and throw on a turbo. I have researched the whole custom kit idea but it just seems like it will be easier for me to just purchase a actual kit. I have decided to go with the hahn kit after riding in a fellow 2gnter's car but am not quite sure which kit I should go with. I am gonna probably have the engine built by VT engines and like I said I want to do 18psi daily since I have 93 octaine gas available everywhere here in Ohio. Should I go with the stage 3 kit from Hahn, minus the internals or should I go with stage 2 and upgrade the injectors? What about the stage 4 kit? Also, I have heard the several things that Hahn includes in there kit is junk such as the bov and downpipe. What else should I have them take out of the kit and what should I replace them with? Thanks Alot guys.
