Ok, the little disasembly went slower than thought. That turbo crap is packed in there pretty good despite the huge engine compartment.
AFM out, radiator out, hood off, bumper off, rad support cut, car up on jacks, driveline not quite disconnected...
Ya, that's all. Doesn't seem like much for 6 hours of work. Oh, spent some time with my daughter this evening too, ok!?! The engine will come out tomorrow!
...then all that fun stuff of new gaskets, paint, timing set, swap manifolds from one engine to the other block/head. yada yada yada
See, I told you I would post pics tonight. 10 min left in the day...

Oh, and the P90head/block that I had already on the garage floor, that thing spings around by hand with no effort. No rings seized up on that bad boy. I sure hope this thing runs good for me when its done!

Looking at that last pic just made me laugh. Has anyone else ever realized just how convenient those head light buckets are for keeping loose bolts and tools from getting lost while you're working on the Z. I love those things and they're a gift from the Z gods

A friend from the Z-Car Club of Washington stopped by to help a bit. That is his blue '81 turbo. He recently did a swap from auto to 5-speed in that car. The engine is all stock.

Yeah I figured it was an '81 Turbo, going by the snowflake wheels. That is sweet, that he converted to a 5-speed. 
Tell him to take care of that nice Z, also ask him what color blue that is. I would like that kind of blue with silver on my Z.

I think that's just the original blue. Blue interrior, blue exterrior. In person, its got a few dings and some imperfections. It looks great in the pics. We tied for 1st place in the 280ZX category at the Meeting of the Mindz 2005. My car looks better in pics than in person as well.
All these little electrical things are sure taking a long time to disconnect. I'm taking my time though and examining everything so I understand how to hook it all back up; taking reference pics too.
anyway, back to the garage...
Wouldn't that be fun to have a Bleach Cam in the garage? I've got high speed internet now... hehe...

Question: Above the ECU there is a small silver box that plugs into the ECU wiring harness. Do I need this? I think so. Its difficult to get the upper mounting screw out... I might have to remove the dash first.
Still working on the wiring. The harness is coming out nice and clean...

Wiring is basically done except for the part that goes through the firewall behind the battery.
You've got the wires going to the fusable link block, and then down into a hole that I assume ends up connecting to the back of the fuse block. Where does this set of three wires go? Should I just cut it and solder it back into the non-turbo body the same? I'd have to rip apart my car a bit to see if its the same.... I'd rather not do that in the pouring rain.
Also, I found the best warning sticker ever...

Ok dudes, due to other stuff in my life I got NO work done on the Z today... yet
The sticker was stuck to the headliner just behind the map light.
Yes, I have done that while driving and so have many of my friends while in the Z. They can't resist. I think I'll be putting that sticker in my car.

If I hook up that fuel pump control, will I need any additional wiring to be swapped besides the ECU to fuel injection wires? I was planning to keep my non-turbo dash wiring and non-turbo gauges.

What if I keep it hooked up to an ignition souce?

I remember debating over & over if I should cut & splice in the needed wires, or just pull all the wiring. After tracing all the needed wires in the schematics, I decided to swap the entire car wiring harnesses from bumper to bumper. Took a long time, but no wiring confusion... no mishaps, and everything worked like it should.

I'm planning to run the NA gauges and add an external boost gauge and possibly oil temp. I'll go with my plan for now and figure out any gauges that don't work after the car is running.

It seems to make sense that the gauges should be ok. The dash goes to the chassis wiring harness which connects at a few locations on the right side of the block and then the temp sensor by the thermostat. This should basically remain unchanged when the turbo block is placed in my car. I'll need to make sure none of my sensors are from the '83 (digital) turbo block. I have an 82 turbo block to use and I can use my non-turbo thermostat housing.
Oil pressure, voltmeter, and clock remain the same non-turbo crap.
Head temp, block temp, are part of the EFI wire harness.
Anyway, just thinking out loud here. The one thing I'm still wondering on is how the fuel pump module will reach the fuel pump if that particular harness is basically separate of the chassis harness... unless I'm missing a vital connection.
If this module changes the fuel pump speed or something, then if I do decide to hook the pump up to just an on/off relay am I missing anything performance wise or just safety-wise? (safety as in, if the car is wrecked, the fuel pump will stay on)
The three white wires going from the EFI harness into the firewall behind the battery are just for power, right?
...I'm going to check eventually, but is there any diffrence in the turbo and NA fuse panel?
