I have been reading about these engines for over a year now. I finally took the time to explore all the "LINKS" from this site and the subsequent links from this sites links.
I don't know what the rules are about mentioning other websites on here so I will refrain from doing so. I will also suggest that the information I did find elsewhere is probably on here too, I just haven't seen it yet.
What I found were some articles suggesting power was engineered out of the lubrication system, whether on purpose or as a by process of engineering from parts on the shelf.
1) the oil pump pick-up screen is overly shielded and that relieving part of the shielding actually yields some usable power.
2) the oil pump supply orifice is oval and that the receiving block orifice is round; by matching the block's oil pump inlet to the oil pump's output, power is recovered/developed.
3) the oil pan system would benefit from a windage tray "device" in the oil pan.
4) the 2.2 and 2.5's equipt with balance shafts/chain/gears will do just as well without them and that they present a power loss to the power plant, and that their removal will provide for the volume of near a full quart of extra oil.
I procured a oil pump pick-up from the yard to give it a shot. (I would like to post the photos but still don't know how to post them on this forum). This isn't the most difficult task but is very easy to mess up. In addition to opening up the inlet to the pick-up screen, I put a chamfer on the outlet tube from the pick-up to the oil pump, may not do much but it will help. I won't be able to install these components until later this coming week unless I finish the heater core swap on Sunday.
If anyone has performed any of these changes I am interested in hearing how things went.
