I was cleaning the egr ports on my honda crx hf, a common procedure unfortunately, and thought upon how the system as a whole could be improved after noticing some things about it.

I noticed there is a coolant that runs along side the egr valve ports to cool the manifold, now I don't know if that is to cool the hot gasses from the egr system or if it is just to keep the intake manifold from getting too hot. IF there is a major advantage to cooling recirculated exhaust gas (to prevent engine knock) could you recirculate MORE exhaust gas if you hooked a turbo intercooler/radiator or perhaps water injection to the egr system?

I would be very interested in the math involved in finding out how much gas savings could be gained from these and I suppose leaning it out further and advancing the timing as well. And the nox emissions too, as that tends to go hand in hand with leaning mixture. we can all agree Nitric oxide is bad I'm sure...

Also the possibly less hair brained idea... what if you hooked up a bubbler like filter box before the egr valve to the system that you could just put clean water in every oil change or something instead of ripping apart the entire intake manifold every 80,000 miles. I think that it would be something like a downsized "scrubber" used at coal fire power plants and the like.
