Overhaul w/ HO Pistons?

Just wondering if this is possible?
I'm wondering because I guess the HO pistons bump up the compression ratio from 16.3:1 all the way to 17.1:1. I was wondering if this was possible on a Non HO motor like mine (98 24v) And anything else to add compression.

Headgaskets??

hmm. most people go the other way when it comes to compression. I would imagine that H.O. pistons would work, I don't know why they wouldn't, but don't take that for fact.

Right, your right. I'm just wanting to bump up the compression for fuel economy.

I think this would be a good route for some that doesn't plan on adding much boost. I dunno I'm throwing idea around, if I overhaul my engine I wouldn't mind bumping up the compression in the name of fuel economy because it does so good already, I wouldn't mind maxing it out.

Do an H.O. pump and injectors as well, I'm not sure if you need different programming to run that pump or not though. That would be really nice. But you would have a cool set up, an H.O. motor with an auto, the higher O/D would probably make for even better fuel economy.

Ya I've been getting wild ideas like that. Also thinking about the issue of Diesel power mag where they take a 2wd housing out for a 4wd housing just to bolt up another O/D by gearvenders. I need a new I/P anyways so I got the gears turning now. Is that HO pump alot better?

Build my truck in the name of fuel economy, even though I don't do much driving any more, but if I decide to do runs across the country, I know I'll have a truck to do it with. My fuel economy in the summer already is blowing me away, it was sucky in the winter and great now that it's summer. But I still have room to work with it seems. Is there a headgasket I can get to raise compression as well, or is stock the best for high compression.


EDIT: I still got to get 4x4 Cummins for the winter, but I think I might keep this one and just have 2 Cummins one for fuel economy. One for winter/ a over all nicer one; mine now is kind of junky. But it runs like a beast.
