self. TT.net can help you thru the process. You just have to search for the deals. I just did a complete na to tt conversion on a friends Z and I spent under $ 2,300.00 from start to finish. Minus the $ 600 to have ash tune the Z. There are members like ( dustthis ) that are selling cmplete motors in the 475hp range for around 6000 dollar range. What ever you do dont short yourself on the much needed items for eday junk. I would start off with a new EFI harness first. It will save a ton of problems. Good luck and take yur time.
