I've also got a SR20DET swap in the garage, it came with the car purchase. Engine is pretty much fully built - pistons, rods, valve train, cams. Doesn't have any of the turbo parts or any injectors though and the head doesn't have the cams in. Wiring harness is a bit rough as well. Also have a transmission for it and the guts for another trans.
I thought about just saying screw the KA but I'd kind of like to feel the car with lower power and get used to it before moving to that. Plus it'll take a few more grand to get the SR ready since it's missing a few things and would need a good tune after that. I'm in a bit over my head I suppose, and don't know anyone around me who's an expert on these.
At this point I'm kind of contemplating just parting out the SR and selling the car..
I've been trying to figure out this no start issue for a few months now to no avail
