Hey Eric I've seen that vid & still gobsmacked at the condition of that beast, I might have to take out a 3rd mortgage to get mine up to that spec hahah!
My car is only an L20a but it's got factory efi running gear for emissions, would probably be one of the first efi setups they'd have implemented. Currently looking around for parts for an L28 build but I want to do all the supporting stuff first ie suspension, brakes & diff before contemplating an engine & tranny swap
here's a quick vid I posted up on youtube to show the z forum guys
It runs really smooth after I put fresh fuel, spark plugs and oil, I think I really lucked out on the condition it was in as it only has a tiny bit of surface rust & all the electrics work beside a dodgy indicator stalk but that's an easy fix, just some fresh solder on the joint will fix it up
