I doubt I will have any trouble with a set of Dana44 front to rear however what can the trans and tcase support. Also what type of fuel management would I need to get, and where would I get a flange and the parts to make the motor live under the positive maniford pressure of a hair dryer?

Fuel Management, megaSquirt msefi.com
Turbo headers I build and the big bore and
stroked motor needs to have 7.5-8:1 CR
at that CR you can run 10-12 PSI boost and
a 1.8 under that will put out 200-220 HP
probably be faster than a 4.3L Vortec

What is the stock cr and how would my computer and EFI respond to the added boost?

a 1.8 under 10 PSI boost and tuned right
would put out as much as a 3.6L V6 and
with a little more boost a little more power.

The MegaSquirt site has other pages of
FAQ and instructions, let me know what
you want to know and I will see what pages
will help you

Durability, with forged pistons is good, but it
all depends on how you use the skinny pedal.
Most turbo motors see a reduction in overall life
but only about 10% over the life of the engine
lower if you don't change the oil and drive it hard
cold, you know all the bad things you shouldn't do

Stock CR is 9.1:1
8V EFI systems don't like boost well, and cannot
supply over 2 PSI boost fuel, the 16V MPEFI is
supposed to be more flexable, but I don't have
any time with that system.

So what should I do with the 1600 8valve that I have now if i want to turbo it? Or would I come out better just to build this motor and work the head and intake? If so what type of power would I get with either? I have a carb setup in the garage so switching to a carb isnt a problem. The only thing that I am afraid of is having fuel starvation. Would I be able to run an aftermarket cam with the fuel injection if I dont go turbo?

Also the intake and whole EFI setup on my sami is via the original 1300.

If you want to go turbo, rebuild the
engine with forged low compression pistons,
the problem is if you don't go turbo the HP will
be lower from low compression pistons

EFI works fine with the aftermarket cams
that are being offered, as would a turbo, tho
a stock cam works well with a turbo also.

Power, about 125  at the rear wheels on
a 1.6 8V  

I don't like carbs with a turbo, blow thru is
good but you need a sealed float bowl and
high PSI fuel pump to keep the fuel flowing
under boost, and if you draw through there
can be problems with seal washdown from
the gasoline going thru the turbo, tho there
are lots of systems on sand rails that draw thru

Was that 125hp n/a or turbo? How would I incorporate the 8vavle EFI and the positive manifold pressure?

N/A hp is 80 at the crank  ;)

8V intake, add some injector bungs
and bolt it on, unless you want to get
some custom manifold made up, works fine,
but you need another EFI to run the boost
enrichment (megasquirt)

So with the megasquit and a built motor I should be able to get 170hp easy? With a built mild bottom end?
