Nice, yeah I had a 87 N/A 300zx and a 84 300zx 50th anniversary turbo that was a pretty fun drive. Well I wanted to post some updates to keep me motivated.
Once I put everything back together from doing the "mess under the intake" mod I went to bleed the coolant system and only steam came out until the temps got really high. After doing a bit of troubleshooting I got bored at work one day and priced out how much it would cost to just swap the entire coolant system for peace of mind. I ended up placing an order from pelican for overnight shipping to get it in time to work on it over the weekend.

Luckily the radiator in it was new (I suspect it had cooling issues they tried to fix and gave up) so the rest of the parts were pretty cheap.
Parts

Parts pile growing... Getting a larger apartment with a larger garage in a month or so... thank jebus...

Engine with old waterpump still intact.

Guess which one is the old one!

Figured I would clean things up a little while I could reach everything. I really wish I would have had the intake manifold and the valve cover cleaned up a little better and maybe powdercoated but I can do that later.

Girlfriend came down to help at just the right time. I was trying to replace the sensors under the intake manifold and her hands are much smaller than mine.

Car put all back together and running great. Couldn't wait to take it for a test drive and it really needed gas so I took it on a quick spin without the hood... or exhaust... but I think most e30's end up doing that at least once.

I have been sanding and painting the trim today and will be dropping it off at the exhaust shop for the new magnaflow setup and I will be moving on to brakes,tires,suspension. Also working on a front Volvo lip but I am only going to use it if I can use a heatgun to bend the sides down.
