10v -> 20v -> 20vt

<<  Take the NF 2.3L 10v engine that I have in my '90 80Q.  Find and attach
the
 20v head (easier said than done I'm assuming, how hard is it to remove and
 replace the head anyway?). >>

First off, if you are going to be swapping around motor parts like this, you
should be comfortable with a simple job like pulling the head, if not, you'd
better practice up before diving into a 20v Frankenstein.

The calculations I have done tell me the NG lower end with the 20v head will
result in about 8.5:1, I am doing some measurments to determine if the
pistons will need to be relieved or not to clear the valves.

<< Use a 20vt exhaust manifold (or RS2 if fanciness
 is desired) with turbo... route the piping back around to the intake
 manifold and MAF. >>

The 7A intake manifold won't clear the turbo, etc, you will have to source a
20vt IM also, or custom make one.

<< Replace the distributer with the 20v model if needed to
 retime everything.>>

The distributor depends on what ignition system you are running, if the
3B/AAN ign system then yes, you would need the corresponding dist., if
keeping the CIS-3 ign. system, then you would have to use that distributor.
The 10v dist will fit the 20v btw.

 <<What am I not seeing?>>

Fueling, not sure how the car would run if you tried to keep the CIS, there
would be issues with trying to fit the CIS injectors for one.  EFI would be
the best way to go.  Also, power steering pump, you would have to custom make
a bracket to fit the 80 power steering pump.

All kinds of other stuff, little things.

Don't take this the wrong way, but by the sounds of your experience level, I
might recommend you do an MC swap first to aquaint yourself with the actual
steps to pulling a motor, building one up, and fabricating the parts to fit a
different motor in your car.
