Rebuild 420A

I have a 420A engine (RS)...does anyone know the best engine rebuild kit and turbo to put in this engine for under 3000$..

thanks

my first answer will be SEARCH!
my second would be that that is a dream, getting a rebuild kit and a turbo system for less than $3000.00.......Don't see that happening for ya, even if you build your own turbo kit.
Let me give you an example. Back when I just got started on dsms I had a gs, and its motor was fresh. I was really dumb and bought the Hahn stage 2 kit for 2,500.00. When I got smart and decided I wanted to boost some more (more than I knew the motor was capable of) I went in and performed a surgery on that motor that would make average mechanics cry, and belive me when I say my wallet was not happy. I am not saying that it isn't worth it. I am just saying to be a little more realistic. If you build your own kit maybe, but other than that search for yourself and find out, look at hahn or star kits. youll understand
