Bringing up this old thread because I'm daydreaming about this. I'm a happy but unexperienced mechanic, so this is far above my current level. I haven't even taken any measurements to see if there is any chance that the Busso V6 would fit longitudinally, but I still like to play with the idea
No sad faces!
My recipe for now:
- Fit the whole rear axle assembly from a Maserati 3200/4200 or Corvette C5/C6. The rear track of both those cars seems to actually correspond to the GTV V6's rear track, at least after some quick reserach. The Maserati option would be nicer, of course, especially since it's got a tiny Alfa connection through the Alfa 8C... Obviously, these two donor cars have a transaxle layout, meaning that the gearbox goes where the rear seats are currently sitting in the GTV 916. In other words, Alfetta GTV6-style!
- Let the power saw go postal on the floor in pretty much the whole car. Need to make space for the prop shaft, the gearbox and mounting points for the rear suspension assembly.
- Welding (yea, that's a skill I have yet to learn
happy amateur!) a tubular frame, connecting the body and remaining floor, to strengthen the car and bolt the rear suspension to it.
- Turning the Alfa V6 around by 90 degrees (praying that it still fits) and going bananas on the fire wall with that handy power saw...
- Convince the engine's flywheel to play ball with the prop shaft
- The fuel tank will be forced to move. The C5 Corvette has dual tanks on both sides of the prop shaft. Perhaps a good thing to copy or even use C5 tanks.
- Whether the OE front suspension will be happy without drive shafts is another question mark. Anyone got any theories?
- Rebuilding the floor
- Building a roll cage "while I'm at it"
- Fitting two not-humonguous turbos so that the engine breathes properly... A maximum weight of 1400kg and perhaps 400hp/500nm (which isn't unrealistic at reasonable boost with an untouched 24V Busso V6 and E85 biofuel) should finally
give the 916 performance to match its sexy shell.
The hardest part is probably to fine tune the whole car to give the same happy and uplifting feeling when driving, regardless of whether you are pushing the car or not
