A rational person would have stopped there

Since I have been away I have started to hord parts for a turbocharger install.
The factory turbo system boosts power and doesn't do much for fuel economy, so I am going with mostly aftermarket parts.
I am going to combind the banks engineering turbo exhaust manifold with a modern Holset VGT out of a 2007+ cummins.
The VGT gives power and economy to diesels.
(remember banks engineering helped build those 30mpg SUVs so I hunted down some of there parts)
I am also going to run an intercooler where banks and the factory setup never did.
I am also building up to run water mist injection (yes it does boost fuel economy on diesels).
And have been considering a day time alternator delete with a twist. Where I Install solar panels on top of my truck to power the electrical system and build bracket with a pully that will allow the alternator V-belt to be quickly removed or installed and tentioned with out tools for night time or PTO use.
(not going to bother with an A/C clutch on an alternator type rig)

Has any one tried any mix of these mods on a diesel or gas engine to get better fuel economy?
Any one have any input on my alternator delete or water injection?
