Welcome to the Third Generation V6 F-Body Modifications Encyclopedia! This guide will help you locate aftermarket performance products that fit your engine. There are dozens of products made for your car and this guide will provide a part number, price, and where to buy it. This guide is divided into several sections based on the product type you are interested in. Use the navigation bar on the left to quickly find information about a variety of performance upgrades. Once you have found an upgrade and you are about to place an order, ask about it on our Message Board to see what other members have to say about that particular product.
 

Intake:

An engine with a high amount of airflow is important when considering modifications. Once you replace your stock intake system, you will be surprised how little the small the opening is that picks up the air.

There is only one intake available for our engines. I recommend that you make your own. It is very easy and is a fraction of the price of buying a professional intake.

Exhaust:

Along with intakes, exhaust upgrades are important for your engine. Exhaust systems give you an increase in horsepower and a more aggressive, louder sounding car.

Computer Tuning:

Benefits of chip reprogramming include removal of the top speed governor, adjustment of shift points for cars with automatic transmissions, removal or adjustment of top rpm limiters in cars with manual transmissions, adjustment of speedometer and odometer due to gear changes, and advancement of piston timing for increased horsepower. Placing a chip in your car requires you to use higher octane fuel to get the full (or any) benefit of the chip. It is recommended that you make the computer chip one of your last modifications because after adding some mods such as a camshaft, headers, supercharger, or nitrous, you will need a different custom programmed chip.

Note: Since there are different chips depending on your engine and transmission, visit the manufacture's web site for part numbers

• Jet Chips
• Hypertech
• Fastchip
• Superchips

160° Thermostat:

Running your engine at a slightly colder temperature improves power output and decreases detonation.

Camshaft

Using a more aggressive camshaft is a great way to gain horsepower and torque. Crane makes a camshaft for our vehicles.

Underdrive Pulley

An aftermarket underdrive pulley will allow your engine to work more efficiently, freeing up lost power. There are several underdrive pulleys to choose from.

Shift Kits:

Shift kits adjust the way your automatic transmission shifts gears. The two major shift kits for the V6 F-Body are made by TransGo and B&M.

Kickdown Kit

Our Third Gen automatic V6's will downshift to third gear when there is more than halfway throttle. This kit will only downshift to third after 3/4 throttle allowing you to cruise at higher speeds in 4th gear.

Differentials:

Third Generation V6's come standard with open differentials. This means that when you do a burnout, only one wheel, the passenger's side, will spin. This Eaton differential below will cause both wheels to try to grip the ground giving you better traction for launches and two wheel burnouts.

Ignition:

Adding an aftermarket ignition will increase performance and allow your engine to run smoother at idle.

Note: As with most high performance upgrades, adding a digital ignition system alone is not enough. To fully feel its benefits you'll need stronger ignition coil inductors, high performance wires, and high performance spark plugs.
 

Spark Plug Wires:

From the ignition box current flows through your spark plug wires to the plugs themselves. As with any electrical current, a magnetic field builds up around the spark plug wires. GM wires are known to be flimsy and prone to magnetic interference, be it from radio signals or other modifications (this is what causes "engine noise", that whining you hear from your speakers if you have a high power stereo but stock plug wires). Adding a good set of high performance spark plug wires is a must if you plan on improving your ignition system.

Spark Plugs:

There are too many different spark plugs to list here. Popular brands for high performance use are Bosch Platinum +4's, anything else platinum, and NGK.
