hey everyone, i am wanting to get some more power out of the 4.0 that i have. i was wondering if you can advise me on some ad ons. should i look into putting a stroker in it. also will the stroker go through more gas. i dont want to get to crazy like putting a supercharger on it. also i want to make sure im not going to have over heating problems

i have every bolt on you can put on a 4.0, and its really just 'meh.' biggest 'seat of the pants' upgrade was the bored throttle body.

So that gave you a lot more power/ how much was it to have that done and how bad did you gas milage get?

on easy nice thing is order a K&N air filter kit off of eba for like 20 bucks ad when you get it toss their rubber carb fitting, its cheap and thin and when it gets hot it buckles. any way take the intake pipe they give you and insert it into stock carb fitting and stainless steel clamp it then take out stock air box and re-cut the opening to fit the new larger intake pipe at its specific angle. its better to spend time on this and measure 3 times cut once cuz you want a tight fit. then make a mold arround the hole with some rubber to seal it bam you just converted stock airbox to K&N air filter plus box. you wont ever have to buy another airfilter just wash it. it also draws air from behind headlight instead of engine compartment
