The 3.8L 1994-04 Mustang V6 was an economical solution to those who liked the looks of the SN95 Mustang but couldn’t afford the more expensive GT & Cobra models. For many teenagers out there these Stangs were often their car. They provide a solid foundation with sporty looks and in the case of the 99-04 New Edge design, decent performance. Sorry 94-98 owners but I have owned both a 94-98 and 99-04 V6 Mustang during my lifetime and the 94-98 models are just sub-par in factory performance.
Just because these models do not feature a V8 doesn’t mean they can’t perform well. Many of the same suspension and exterior components can be switched out with GT or Cobra parts to easily dress up the exterior and improve performance. Being that I have owned two of these V6 Mustangs, I wanted to share some of the experiences I have had modding these Pony cars. You can make them extremely fun to drive and best of all many of the performance, handling and exterior mods won’t break the bank.
Before we look at performance modifications, let’s look at some of the specs and horsepower found in the 94-04 V6 Mustangs.
With the New Edge Mustang redesign in 1999, the 3.8L V6 underwent some changes that gave it a good boost in horsepower. The engine kept its OHV design; however the intake system got a major redesign with a larger throttle body, split port design intake manifold and better flowing cylinder heads. This added an extra 40 horsepower over the previous year model.
Below you will find modifications broken up into multiple sections for easy selection. These include air/fuel, exhaust, engine, driveline and suspension modifications. Each section includes a more in-depth look at ways to improve your V6 Mustang!
The one mod that all V6 Mustang owners should do is install a dual exhaust conversion on their Stang! Not only do you get performance gains but you also get a deeper more aggressive exhaust tone with improved exterior appearance! Installation of a V6 Mustang dual exhaust kit will get rid of the ugly single exhaust tip and allow for your exhaust system to “exhale” better. This means increased horsepower and improved fuel economy! There are multiple options for installing a dual exhaust on your 3.8L Pony. One of the easiest ways is to pick up one of our complete kits below that features a mid pipe and cat back system. These are available in both an x pipe and y pipe version. If you want to maximize your exhaust performance you need to go with the x pipe version.
You can also build your own V6 dual exhaust system. This will allow you to pick and choose a system that fits your personal taste and performance needs. Use the following steps to build your perfect V6 Mustang Dual Exhaust System!!!
Installing a set of rear end gears and a traction lock differential are some of the easiest ways to improve the acceleration of your V6 Mustang. The factory rear end that came in the V6 SN95 and New Edge Mustangs featured a 7.5” rear end with a differential that only sent power to one wheel and a gear ratio that was designed for fuel economy not acceleration. This results in the “One Wheel” burnout …if you could even get it to burnout! Combine new gears with an aluminum driveshaft and a short throw shifter to maximize acceleration and shift performance!!
Installing a set of lowering springs not only improves the stance of your V6 but it also improves that handling characteristics! Most 94-04 V6 Mustangs did not come with rear sway bars. So installing Cobra or Eibach sway bar kit will only further improve your handling. If you have modded your six banger with plenty of performance mods from above you are now also experiencing “wheel hop”. This can be eliminated by installing a set of rear control arms. Once installed you will be able to plant your new found power to pavement and improve your acceleration.
