Feeling like I should've gone and grabbed this already to flip to one of you moneybags. It's a screaming deal if the motor is good. Big IF though.
If the motor needs going through you could spend $2k right quick, I'd guess, and still be only half through it. Timing belt kit set me back $350 or something just now. The head gasket kit was something like that too, if I remember right. That's before you get into hard parts and machine work. So. IF.
The harness is a be-otch to make even if you have a donor car (as I do). But there is a guy in CO or Canada (I forget which) who will sell you one for like $600, give or take $100. I'm probably going to end up paying him to do mine.
The computer is a boneyard item. Hard to get to but not too expensive, I hear, and they don't tend to go bad. The ECU from any older Sooby will work fine with a turbo setup, according to the boy racers on every Sube-centric board. For what that's worth.
Or you buy the megasquirt and study-up.
