Coffee Brake: What Engine Goes in Here?

Time for another Coffee Brake, DT’s feature where caution is thrown to the wind and mysteries of the universe are pondered.   Today, as suggested by slowcarSLOW-MPGlol, we look at an empty engine bay in this 996 generation Porsche 911 and try to figure out what belongs inside.

This 1999 Porsche 911 is offered for a resonable $9,500 without an engine, it was probably a victim of the dreaded rear main seal failure that led to secondary and catastrophic engine damage.  It is an extraordinarily expensive engine with new examples running $18k from a Porsche dealer, so it would make sense to replace it with something cheaper…but what?

The biggest engine available in the 911 today is a 3.8 liter flat-6, so why not keep the cylinder count but up the displacement to 4.0 liters with an AMC 242 inline-6.  Performance with 190 horsepower and 225 ft-lbs of torque will be abysmal…so it’ll need to be fitted with the all-wheel drive system from the C4 and lifted 4 inches and ride on 33 inch Super Swamper tires.

What would you shove in the back of this roller 911?
