In Too Deep With Your LS Swap?! A New Company Can Help.

PSI Performance Systems Integration

New Jersey’s LS/LT Engine Swap Headquarters

Strategically situated halfway between the hustle and bustle of the high-density population centers of Philadelphia (78 miles) and New York City (an even 70), lies the home of Performance Systems Integration—or PSI for short. Established in 2008, the Brick Township, New Jersey based company has become a leader in the design and manufacture of standalone wiring harnesses for GM Gen II (the previous LT1), III, IV, and V LS- /LT-based engines and transmissions.

Once inside their showroom, you’ll see that PSI has a ton of sample set-ups and storyboards filled with their latest products for the LS/LT transplant.

And there’s more. With LS/LT conversions popping up on every make and model car out there, the folks at PSI have done their part to make the transplant of these engines in Brand X models as seamless as possible. PSI have expanded, and now sell just about everything you need to put an LS or LT in your Buick, Olds, Pontiac, and even your pony car. Yes! PSI sells the needed pieces to solve your Mustang-to-LS (or LT) power puzzle!

Here, Jon works on the project C1500 company shop truck, installing the new front brakes that will stop this beast in the near future. It’s an LS-based engine swap which will receive all the PSI products it can handle.

If you’re just hearing about PSI now because you just jumped into the LS- /LT-swap world, don’t let the young faces of the PSI crew fool you into thinking they’re an overnight success. They’ve been at it for the better part of two decades on their own and together, so if that’s an “overnight” success, then so be it. Having worked with professional car builders and DIY hot rodders both domestically and overseas has given them the confidence to jump into any type of LS or LT swap.

Research and development is vital to moving PSI into the future. Co-owner Joe Balesterri dives into an LT engine to help create new products for future hot rod projects.

PSI co-owners Jon Vezzosi and Joe Balesterri met in college where they were both mechanical engineering undergraduate students. Soon, the pair went to work in the aerospace industry in their respective fields at the same company. The fast friends had common automotive pursuits outside of work, as both came from hot rodding backgrounds. They soon realized their shared interest in perfecting modern Chevy-based engine conversions. They then decided to start their own company, catering to the busy LS/LT engine sector, realizing a heavy need for products to help consumers successfully navigate modern Chevy engine swaps into classic vehicles.

Even writers need help sometimes. PSI’s marketing guru Nicollette Haines shows the Car Craft staff how to traverse through PSI’s modern website. There you will find all the products you need to pull off your LS/LT engine installation.

Jon had done several GM swaps over the years for both himself and several friends, and used these experiences as a starting point for creating needed standalone harnesses to help with today’s LS/LT swaps. “We started sourcing parts to build these pieces—connectors and components to create our custom harnesses from,” states Jon. From there, prints were made and then the first harnesses rolled off the two-man assembly line based in Jon’s garage. “We started small, very small,” laughs Jon.

Here, head tech-head Gary Stoddard (r), and sales reps Jeremy Marcuse (l) and Dana Kermes (c) discuss parts options for a client’s Chevy-powered hot rod. Gary has been with PSI for the last five years, and spent thirty with GM prior to his employment with PSI. Jeremy has been the head of sales for five years now, working with Dana for the last four here at the company.

There was plenty of R&D done to bring these harnesses to the general public. “There were a lot of questions to be answered, things like how long should the harnesses be to work with cars of different makes and lengths, so installers wouldn’t have a mess of extra wire and harness that they now needed to hide,” states Jon. It took time, but PSI found a way to create harnesses that work well with basically any car or truck out there. For a list of various LS and LT engine harnesses by engine RPO code (ex. LS7, LS3, LH6, etc.) click here.

Need your ECM programmed to work with your new set-up? Not a problem at PSI. Chief programmer Keith Graves downloads an updated program onto a customer’s ECM.

PSI grew quickly, which led to Jon and Joe to seek out needed space for expansion. They stayed local, picking conveniently located Brick, New Jersey for their headquarters. Just minutes off the Garden State Parkway, the location gave them a locale which could be easily reached by staff and customers in the tri-state area. With the space they needed, the company had room to grow and diversify.

PSI offers over 100 different standalone harnesses made exactly for your combination, right here in the good ol’ USA. If you need something modified to fit your needs, just ask. Here wiring harness technician Matt Bergstrom goes through a customer’s harness order to make sure it will properly work with his set-up.

PSI has now branched out into other LS-/LT-swap products, and stocks a warehouse full of mechanical and electronic aids—many of them made in-house, but also from other vendors. Years of helping customers find that hard-to-find “missing link” part or tuning tip means your LS or LT swap is going to be a whole lot easier in a hurry. PSI services and components include gauge clusters, A/C systems, engine sensors, and additional items to get your powertrain conversion completed. Whatever your LS and LT swap needs, PSI is there to help, so give them a call. Want to see what’s up with PSI, but don’t live in New Jersey? Make sure to check them out at the Holley LS Fest, this September 6 – 8, in Bowling Green, KY.

After starting their company in co-owner Jon Vezzosi’s small garage space, PSI has moved into a spacious and modern storefront just off the Jersey Shoreline in Brick, NJ. Here there is ample space for the needed office, tech, and R&D areas that PSI needs to grow their business.
If you have a need for a standalone harness for your LS/LT engine conversion or the many parts needed to see your Chevy swap come to fruition, odds are PSI has what you’re looking for. The shelves are stocked to the brim, and all products usually ship within two business days. So what are you waiting for? Wire it up, and fire it up, with PSI!
