4X4 Parts - Engine Performance Products Buyer's Guide

Regardless of what brand engine, displacement size, number of cylinders, or rated horsepower that our rigs have in them, if you are like the 4WD&SU staff, we're constantly on the hunt for more power and performance from our engines. With this said, please join us in viewing some of today's latest and greatest engine performance products - and yes, some of these items are full engine conversions because sometimes a new engine or a stroker motor kit may be the only way to go.

Keep in mind that increased engine performance may be the result of a new radiator, a larger motor and the necessary hardware to install it, new wiring harnesses, and even a transfer case to deliver your newfound power to the vehicle's wheels. All of these components are equally important to each other, and we must always remember this synergy amongst the parts.

FLEX-A-LITE DUAL ELECTRIC FAN KIT
It is important to remember that when the engine size increases, so do the cooling requirements. This requirement is especially important if a larger engine is being placed in a smaller cavity; there needs to be sufficient cooling due to the restrictive space. These two huge 15-inch electric fans move an impressive 5,500 cubic feet of air per second and are encased in a glass-reinforced, nylon mold-injected shroud.

The benefits of having electric fans while off-roading are monumental. Quicker warm-up and cool-down times, increased fuel economy, and a cooler running engine are just a few of the benefits. Horsepower gains have also been noted to exceed 17-plus while rear-wheel torque increases 20-plus lb-ft.

FORD RACING PARTS 520 CID V8 CRATE MOTOR
Ford Racing Parts is proud to offer its '04 520 cid V8 crate motor, which puts out a staggering 625 hp right out of the crate. The 520 cid V8 contains nothing but the best that Ford Racing Parts has to offer. With a 9.8:1 compression ratio, custom valves, custom ground crankshaft, and custom-polished Ford Racing valve covers, every item on this powerplant is built with race precision and craftsmanship for durability and the ultimate in performance.

Harnessing all of that power along with the 600 lb-ft of torque that is produced will prove to be a challenge for any fabricator, but it will definitely be worth the time, effort, and money spent.

NOVAK GM GEN III ENGINE MOUNTS
Installing a Gen III GM engine into a Jeep TJ/LJ just got a lot easier with Novak's engine-mount kit. Each kit contains high-strength steel mounts that have been seamlessly welded to ensure the utmost strength. The 3/16-inch-thick steel mounts have not been drilled to allow for precise engine placement inside the bay. Gusseted frame brackets are designed to be welded to the inner framerails, allowing for added strength, while high-grade urethane isolators are gauged to provide ideal balance of isolation and firmness. Large 5/8-inch bolts and all associated hardware are included in each kit.

GEN-RIGHT SC FUEL TANK
More often than not, when swapping one motor for another, there are numerous other parts that must also be replaced. A fuel pump and fuel tank are just a couple of these items due to the high-pressure and high-volume fuel pump requirements that V8 engines have. Created especially for Jeep TJ and LJ models, each tank is made from 1/8-inch-thick aluminum alloy and is assembled in a foam-lined, matching heavy-duty 3/16-inch-thick skidplate with straps and factory Mopar rollover valves.

PAINLESS PERFORMANCE WIRING GM HARNESS
One of the most daunting tasks associated with swapping engines is the rewiring and integration of the new engine harness with the remaining wiring of the transplant vehicle. Painless Performance's newest wiring harness makes the integration of a GM EFI engine into any vehicle a breeze. This factory-style replacement harness comes complete with factory connectors and terminals and is color-coded to plug directly into the factory ECM.

Designed to mount the ECM on either the firewall, underneath the dash, or in a kick panel, this harness will take the stress out of this portion of your project.For more information, contact:

ATLAS II AND ATLAS 4SP TRANSFER CASES
Now that you've gone through the engine swap on your rig, the next step is to apply that newfound power to the wheels. Enter an Atlas II or Atlas 4SP transfer case. These bulletproof transfer cases are available in a variety of configurations and gear ratios.

The Atlas II and the Atlas 4SP cases are both cast of 356-T6 heat-treated aluminum alloy and loaded with hardened 8620 shafts and helical-cut gears. Their ease of installation only makes them more attractive of a project.

HOWE RACING CUSTOM RADIATORS
As you may have already found out, installing a specific motor in a vehicle that it is not supposed to be installed in may require some level of custom components. Typically a radiator is one such item, given the configuration of the engine bay and required cooling capacities. Howe Racing offers custom-designed radiators for just this purpose. Upon receiving your design and specifications for the unit, a U.S.-made aluminum radiator core is selected and fabricated to allow for maximum heat transfer and dissipation.

Each radiator is typically more than 7 percent cooler than a flux-bonded aluminum core unit and more than 15 percent cooler than one of copper and brass. Each radiator features a cast or billet filler neck and uniform height core flanges. They also feature crimped and welded tanks and are TIG-welded by hand to ensure exceptional quality and appearance. Each radiator is pressure tested and guaranteed against manufacturing defects.
