what would be the easy and cheapest way to get some decent horse power under the hood ?

 

intake, exhaust, chip, pulleys, fans, Nitros, Supercharger in order from cheapest to most expensive......

 

sdf150guy gave some great advice. I would just add that for the biggest bang (horsepower) for the money then get a Superchips. I believe it will get you like 20 - 25hp for the V-6.

 

i am wondering why the electric fan kit costs almost $500. 2 fans a shroud and a thermostat. what else is included? i saw a figure for horsepower increase of 30hp??? is that true? in the long run, you'll save the cost of the premium gas that the chip can rob you for.

 

Get a new engine!
You'll never get a lot of HP out of the 4.2 w/out lots of $$$$$$$$.
