Converting to an engine

My 1.6 VW engine is getting tired, so I have to do something. I have the choice between rebuilding my engine, buy a rebuild engine, OR swap the engine to a watercooled one. Because the first to options where quite expensive AND the quality of engine parts and rebuilds is getting worse, I decided for the watercooled one. It will cost me roughly the same (maybe a little less) then the vw engine, but I would gain horsepower, smoother running (fuel injection) and it will produce less engine noise. Plus I would have a heater without a slight smell of exhaust fumes. Another plus would be running the beetle on the freeway at 120 km/h knowing that this engine should be able to do this without problems.

I decided to convert to an Alfa Romeo engine. Why? See the first link in my to-do list:

The To-Do list:

Not entirely in chronological order... choose and buy an engine buy adapter kit (from DS-tuning) create an engine trolley clean engine replace old and worn rubber gearbox mountings fit engine to the engine bay, I'll have to cut away (part of) the bumper brackets. make rear fenders and apron fit Cooling system: At first I had the radiator in the back, but this didn't work on the highway (read more about it here). Now I am putting the radiator in the front. install front radiator add parcel shelf area to engine room place the header tank & create/attach the coolant lines find a place for the heater and it's hoses and ducting run coolant pipes from front to back Fuel delivery/return: place two fuel lines from front of car to back fabricate return inlet, place the fuel pump and an injection fuel filter Wiring: sort out the engine management wiring buy workshop manual for Alfa Romeo 33 1990-1994 wire-up a temperature-gauge, rev-counter and indicator lights connect throttle cable to Alfa throttle cable find an alternative for the standard airfilter create an exhaust16-03-2009 create brackets for the rear engine support and rear apron perform basic maintenance on engine16-03-2009 Change gearbox?
