I guess maybe I need to clarify my intentions.
I want this to be as reliable as stock, but would like it to be able to reach a sustained 65-70mph for say an hour or so when needed, highway driving. It will spend most of its time in the 45-55 mph and under range. I was hoping to do this with a few upgrades and bolt ons, possibly a slight bore, but not a ton of machine work. I'm not looking for serious gains like a Turbo swap would give. I'm a jeep guy and have zero experience with these, I have no baseline to go from as I have no clue what a "fresh" Raider 2.6 is capable of MPH wise.
