Our beloved Teal-J Jeep has seen her share of modifications over the years, and one area where we never seemed to get enough performance was the stock 4.0L six. Its factory-rated 181 hp at 4,600 rpm and 222 lb-ft of torque at 2,800 rpm were adequate for the vehicle in base trim, but with the hundreds of pounds of extra weight that we've bolted onto our Jeep in the form of aftermarkets axles, wheels, tires, and body armor, our 4.0L was beginning to act a bit sluggish, leaving us looking for power upgrades. This is why, when we saw a 345 hp 5.7L Hemi-equipped TJ Unlimited at Tera Manufacturing's booth at last year's SEMA show, we were hard-pressed to take it for a spin. So we asked, and much to our surprise, they said sure. One blip of the skinny pedal and we were sold.

Sweeeeeettt
Thanks to Tera, this swap is easier than you might think. Not only are these engines popping up everywhere as late-model Dodge Rams are wrecked, the swap itself has been totally mapped out, so very little homework is necessary to execute the conversion. Our donor Hemi came out of a 3/4-ton '04 Ram--which can save thousands of dollars over the cost of a complete new Hemi turnkey assembly - and it exceeded our expectations in both fuel economy and acceleration.

We decided to break up this install into two parts because it's composed of so many steps. So follow along as we show off the stuff you'll need to get a Hemi under your TJ's hood. Next month, we'll tackle the cooling system, exhaust, and transmission shifter as well as showing off the Teal's Hemi-enhanced performance both on- and off-pavement.
