Hi

I was thinking of the following mods. And need some advise/user expirience.

- Installing LPG injection in a turbo diesel.
Costs is around 2000 to 2500 euro's.
Payback time is somewhere between 100 000km and 250 000km

- waterinjection: injectin water under high pressure trough nozzle in the intake air stream.
Cost???
Wear of the engine?
How much injectin?
How big of a tank?

- I drive a lot on highway. And went from 6l/100km with constant trotle. Tot 5,5l/100km with puls and glide.
Now i was thinking. If we design some sort of electronic circuit that would change the combustion cycle.

Normal cycle of the engine is 2 revolutions for each combustion. If we design it this way. It would be 4 revolutions 1 combistion. So we hack in to the injectir signal with elecronics to block 1 combustion cycle and let the next one trough.
Expecting to drive on 2 cilinders on the highway wen the revs are high (above 2000rpm) and continiuesly change the cilinders that are inactive. So the entire engine keeps balanced in heath.

And so on

Other mods to do?
