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.
