Engine mods?

Other than an intake and an exhaust, what else do you guys have done to your rangers? I'd like some more power. I was thinking of getting a chip too. I have a 2000 4.0, but its a 5 speed manual. So which chip seems to be the best for it? Thanks!

All factory engines have had Cold Air Intakes(CAI) since fuel injection was added, and have close to 200% more air flow than required, this allows air filter to get pretty dirty before in needs to be changed.
So no help on that end.
These can look and sound better, and no harm in that, but just know going in that the reason for most things like this is aesthetics, i.e. painting flames on the side will give you the same power increase.

Exhaust changes, if done right, can change where the power band resides in the RPM range, it doesn't increase power, just changes where you get it in the RPM range.
If done wrong you lose power.
Your factory exhaust has power band in the RPM mid-range, you can get "headers" that will move it lower or high in the RPM range, it doesn't make the power band wider.

"Chips" don't work, nothing more needs to be said about that.
Sending your computer out for tuning can be considered but isn't cheap for the small gains on stock engine, this is usually done after getting a bigger cam or turbo/super charger.

The way you get more power out of any engine is simple, add more air.
A 5.0l engine produces more power than a 4.0l because it can pump more air per minute, simple, "there is no replacement for displacement".
More air means more fuel which means more power, laws of physics.
A turbo/super charger adds more air
A bigger cam adds more air

So unless you can add more air you will be wasting your money on bolt on type "power boosters"

To get more available power to the wheels, remove the belt driven fan and install an electric radiator fan, that will for sure free up some power, not much but not 0 either, lol, also it is a better setup in general.

Power to weight is another thing to consider, a V6 in a Ranger and the same V6 in a Smart Car, which would be faster in 1/4 mile, lol, why?
Lighten the load

Look into the throttle body cable mod. It doesn't really add power, but it can give you a little extra throttle range depending on how much your cable has stretched. There's a few youtube videos on it.

Isnt that the mod where you put zip ties on the throttle cable on the pedal to take up the slack so the throttle body truly opens up all the way? I did that on my Explorer a while back. It actually helped a bit.

Yeah, that's what he's talking about. Quick, cheap "mod" that helps performance. Doesn't get much better than that.
