Using 930 turbo top end on a 1991 3.6

I would like some help with knowing compatibility issues of using the top end components of a 930 turbo, and the long block of 1991 964, 3.6

I have a chance to pick up the long block from a car that was burnt. At a reasonable price.
I would like to put it in my 1982, 911

Here are the parts I have

930 components
complete intake manifold with accessories
CIS fuel distributor with lines and injectors
complete exhaust system
waste-gate
K27 turbo
oil scavenge pump
lambda computer with harness
diverter valve elbow
Bailey Motorsport diverter valve
Stock inter-cooler complete with piping.
Air-box

Any help would be greatly appreciated!

for starters the intake flanges are not compatible and at 11.3:1 the compression ratio is going to be way off

Head stud spacing alone kills the deal.

BTDT, and it's a long, tedious, and expensive process to do it all.
* 964 compression too high
* the 964 exhaust valves aren't sodium-filled
* intake ports are 3-bolt -- adapters needed
* exhaust ports are much larger than your exhaust
* no provision on 1-3 camshaft for scavenge pump
* the 930 CIS won't keep up all-stock
* fan shroud & ducting

* and then you'll still encounter all the usual late-engine-in-an-early-chassis issues: engine sheetmetal, p/s delete, crank pulley, A/C, engine oil cooler, throttle cable...

Honestly, easier to build your engine. You'll get a "new" engine instead of replacing a known used engine with an unknown used engine.
