The Gen-III are rated at 175HP so I would assume that the Gen-I are in the 160HP range (Flywheel HP...not rear wheel.)

The Gen 1 dakotas only have 125 HP because they dont have magnum motors in them. I am looking for a Gen 2 dakota because they have 175 HP and a sleeker body style.

All Generation I 3.9L V6 Dakota's have a measly 125 rated hp's. Sad, isn't it?

So does anybody know possibly how much more horsepower i could get out of 3.9L with 125HP now. If I were to spend lets say $500. And what would be the things i should do first. Anybody?

Actually, it's 175HP at the crank but subtract 20-25% for driveline loss (average is 22%). This puts the rearwheel HP at 136-140.

For $500, hmmmm....

Home-Brew Intake System w/K&N Filter, Fastman TB, 180 T'Stat, Autolite 3923's, Accel Coil w/harness, and a Dynomax Super Turbo to replace your factory muffler. That'll get you about 10-12 more HP.

Oops...just notices the '89 model. (Electronic Carb.) Don't know who does anything for them but Mopar Performance has Cams, Valves, headers, etc for the 88-90 models. :)

Bernd, the early Gen I Dakota's have a measley 125 hp produced @max RPM's. I have the original sales brochures to confirm this.

I plan on getting my 1989 Dakota 3.9L dyno tested sometime soon to see what I'm getting. I have a K&N open air element, Jacobs Omni Torquer ignition, JET stage II chip, 91 octane, Mopar headers, 2.5" custom exhaust, Borla straight through muffler, no cat, K&N crankcase breather, disengaged smog pump.

I'm hoping all of this combined will net me 40 more hp's on the dyno. But we shall see....

If you want modification and upgrade information, check out our website for early Generation I Dakota upgrades:
