760 Engine replacement questions

I have an '85 760 turbo Automatic whose engine is on it's last legs.
I would like to keep the car but wonder what options I have as far as
replacing the engine.

Does anyone know if I would be able to put an engine from another
model/year or would that entail too much headaches as far as replacing
computer modules and so on???

the current engine has 370k on it and a few valve guide seals and
burnt valves i suspect. I can get a exchange engine for $700 but who
knows hoe long a replacement would last as it is not necessarily a
rebuilt engine.

Is it worth it tome to rebuild my current power plant?? Are
aftermarket rebuild parts easy enough to get???


I appreciate any info you have!!

Would you recommend replacing the older Garrett turbo with a newer
Mitsubishi turbo at the same time as the engine swap?

I like the Mitsubishi in my 740 better than the Garrett in my 240 for
everyday driving, however the Garrett is a better choice if you want
significantly more than stock power. For a stock engine the Mits is a bit
nicer because it spools faster.

 

There's no difference to the physical layout of the motor. Newer cars
have a different fuel injection, flywheel pickup instead of hall sender
in distributor, but all the "old stuff" from your motor will just bolt
on and work. No modifications necessary.
