Nice looking 1994, my 1994 looks a little more "used"
I have the same truck in Red, 4.0l, manual, 4x4
Not much out there for the 4.0l OHV engine, 160hp
Ford switched to 4.0l SOHC engine in 2001 to get 205hp in a Ranger.
It already has Cold Air Intake, a good fuel injection system, and full air flow.
Exhaust is tuned, but for mid-range "boost", you can get headers that will change it to low-range "boost", or high-range if racing.
Roller rockers are available, you can port the heads, and shave them for higher compression, it's 9.0:1 now
4.0l SOHC engines ran 9.7:1 ratio which is where the extra HP came from
Loosing mechanical cooling fan and putting in an electric fan will increase power and MPG, one of the only changes that can do both.
But it ain't much, maybe 3-5hp
They do make a supercharger for these, but not a cheap option and of course you can blow out the bottom end, if boost gets too high.

Many thanks and much appreciated - guess I'll just keep it as it is. Actually I just bought an F150 / 5.4 (only 2wd) - but to be honest I prefer the Ranger so I think the F150 will go! Ranger is far more practical.
But will have to keep my eyes open for a newer version - maybe import one from the States .....SOHC engine, 4wd, manual and semi extended cab :)
