About 3SX


3SX Performance was opened in 2000 with one goal in mind: Performance options for the Mitsubishi 3000GT and Dodge Stealth, both the TT (for Twin Turbo) and NA (for Naturally Aspirated or non-turbo). We strive to develop new products that are not yet available in the marketplace, and offer the widest selection of parts for the platform. Pioneering parts such as the Lightweight Aluminum OEM and Underdrive Pullies, Poly Motor Mounts, and Adjustable Rear Control Arms that were unheard of at the time put 3SX on the performance map. 3SX has provided parts to help the 3S launch harder, brake quicker, turn sharper and just plain look better with offerings from sway bars to full coil over suspension kits, upgraded brake pads to all out big brake kits, intake pipes to complete engine internal replacements like rods and pistons. We have nearly every part you could want to make your car into the beast you always dreamed it could be.



The driving force behind the company is our employees. Each 3SX Crew Member lives for performance. From founder Steve Burrows' highly modified 94 VR-4 monster to original crew and General Manager Eric Bowden's “222 HP Stereo” 93 Stealth RT, each and every Crew Member eats, sleeps and breathes better performance! Part of what makes 3SX a popular company is the fact that, unlike most online "shops", we actually ARE a physical shop, actually STOCK what we sell, and WORK on performance vehicles for a living.



With customers in over 99 countries around the world, the entire 3SX Crew works very hard to ensure the highest level of customer satisfaction by offering exceptional customer service, product knowledge, and experienced service technicians so you will be confident in your decisions regarding parts upgrades and service.


In 2004 we moved into our current 12,000 square foot facility (above), finally reopened our service bays and expanded our shipping capacities. This building gave us more room to stock more parts, improve shipping times, and allow us to expand our overall offering to the 3000GT and Stealth community.


2006 brought about further growth with the addition of a second 10,000 square foot facility dedicated to vehicle service and engine building (below). This freed up space for BOTH sides of the business to grow: we have room stock more parts for our worldwide sales, and service had room to accommodate more vehicles and technicians. We built the new Service Facility to truly be a complete performance service center: plenty of lifts, "clean room" for engine building, transmission teardown/assembly room, "fab lab" for custom making whatever is needed to complete the job from small brackets to custom piping and more, showroom, and customer lounge.



We also took a big step truly in the performance direction by launching our 3SX Racing division in early 2006. This was not only to race and prove the parts that we carry, but also to serve as a research and development platform to develop MORE new parts with high-end performance in mind. 3SX Racing was been a huge success, campaigning both T2 (our FWD 3000GT Drag Car) then T4 (our AWD 3000GT Drag Car) and to world records for the FWD and AWD 3S platform.


We completed one of our major projects in very early 2007, opening our SuperFlow AWD Dyno to the public! This new offering gives us the ability to tune virtually any vehicle on the road. Now, when we build your engine, you have the option of getting the best and optimal performance from your vehicle. Or we can simply strap your car on and see how much power it makes. It also furthers our R&D because we can actually test products in a controlled environment on the dyno and prove them on the track.


3SX survived the economic downturn of 2008 and on WITHOUT laying off a single employee! We tightened our belts as necessary and made sure that we would be the shop still standing for the long term.


As always, 3SX is dedicated to the future! We always have a number of R&D projects up our sleeves that we work on... Our service & dyno tuning facility is booming, and we have added experienced and respected technicians to help support our growth in the 3S market as well as into other makes and models, giving us the strength to not only work on your 3000GT/Stealth, but almost any other car you might want to take to that next level!


2012 was the big year of change with two big new developments: 


TPF Cars, and The Performance Factory.

TPF Cars is our expansion into a completely new market - vehicle sales and custom locator service! Our 3SX Cars division offers a unique collection of specialty and customized used vehicles for sale ranging from souped up turbo cars to classic hot rods and custom trucks! But the big offering is our custom locator service. If you are looking for something specific, regardless of what it is (short of maybe an Abrams tank!) you can contact one of our sales representatives and let them know what you are looking for and we will do our best to find your dream car!

The Performance Factory is almost a grassroots movement that swelled up from within the service department itself. Our technicians bring a very deep and broad range of experience to the table. The guys decided they wanted to essentially branch out from under the "Mitsu shop" affiliation that "3SX" tends to carry to better represent that division of the company. Thus "The Performance Factory" was born! With experience ranging from serving on professional race teams, welding and fabrication schooling, and histories in a number of automotive brands, the "We Manufacture Horsepower" is now the prevailing theme! So whether fuel injector or carbureted, turbo charged or naturally aspirated, 100hp or 1000hp, or any combination thereof (!!!), The Performance Factory as a division of 3SX Performance Automotive is your destination for having your vehicle built and tuned to its potential!


With all of these new endeavors and exciting changes weighing on the future, we are looking forward to meeting YOU and hope you will look to us to be your premier performance automotive destination!
