I do not want to even mess with a ls based engine when it comes to codes. I do most of the work myself with hel from my brother and friends and we do not have the equipment for them. But I have changed my mind again. I would like to twin turbo it now from seeing what other people are getting for hp and torque.
From what I have found it will cost around 7 grand for heads, fuel system cams, crankshaft, pistons, rods, tranny and turbos with piping. With everything else I would like to do to the truck it would be a total investment of around 12-15k and not having a payment on top of that.
It would be epic to pull up next to a pos ricer or some pile like that and tow them at a red light. Also kick my bosses challengers ***.
