Do you have the ability to fabricate stuff? You can do a turbo kit for dirt cheap for a few grand if you build it yourself. As far as efi for a few grand you could do megasquirt for a little more you could buy a used fast or big stuff 3. Also if you found a core block you could rebuild that with good parts cheaper then you could buy one for. If you wanted a turnkey setup you will have to pay for peoples talent if you do it yourself and shop for deals you. An do it on the cheap. I found my 6.1l for 2k with wiring and trans it was posted at 3pm I called and agreed to buy it by 5. Good luck
