Porsche® Boxster 2.5L Twin Turbo Upgrade.

The long-awaited turbocharger upgrade for the nimble Porsche Boxster!

TurboWerx is the first and only source for a complete Boxster twin turbo upgrade. This user-installable, bolt-on twin turbo kit is designed to seamlessly add 65+rwhp, 66+ ft-lbs to any 5-speed 2.5L Boxster... beyond Boxster S performance...all the while keeping your factory drivability, mileage, and emissions. TurboWerx thoughtful engineering has produced a complete kit simple enough for the mechanically-inclined owner to install themselves. In fact, most installations can be accomplished in about 8 hours, which is less than half of supercharger-based systems.

TurboWerx has developed custom ECU modification technology to make the upgrade complete and safe. The modification allows the new, larger fuel-injectors (included) to operate with factory precision.

No off-the-shelf turbo would match the performance required for this application. Working closely with the industry-leader Garrett, TurboWerx developed a custom turbocharger specification perfectly matched to the Boxster's needs.

No forced-air performance application is truly complete without an intercooler. The TurboWerx upgrade kit includes an air-to-air intercooler for not only the safest possible operation, but additional hp. Not only just more horsepower - but just plain smart.

Thanks to the custom ECU programming, the intercooler and an extremely efficient turbocharger, the upgrade boasts a full 6 psi of boost pressure. The system is so efficient, that significant boost is achieved at less than 2300 RPM. These performance levels are simply not achievable without taking a systemic approach to the design. The end result is a upgrade package unmatched in performance, reliability, and cost.

Performance and versatility. These are two reasons no others can match the power and boost level of TurboWerx Turbo Upgrades. Using efficient turbochargers and intercooling safely allows 20-50% more boost than supercharging systems can provide - 6 psi vs 4-5psi. (For an in-depth comparison between a supercharger-based system and a turbo-based system, see the Competitive Questions - Fair and Balanced in our FAQ's, Updates, etc section.) For certain applications, such as racing, TurboWerx systems can very easily increase the boost level for even higher performance. On the track or the street, turbochargers are the best choice. And no wonder turbochargers are what Porsche® engineers always chose.

If you have already invested in an aftermarket muffler and/or performance catalytic converter replacement, you already have a perfect complement to the turbo upgrade. This system is designed to be 100% compatible with both the stock factory parts, as well as ALL aftermarket cats, sensors, mufflers, and tips. And if you have improved or bypassed cats and/or muffler, your performance gain will be even greater.

Only the highest quality materials are used in the manufacturing of the components. No cheap Chinese-made items here! The headers and downpipes are crafted from stainless steel, just like Porsche®. The oversized polished stainless steel offers the lowest possible intake restriction, as well as cold-air induction. Piping is mandrel-bent and precisely welded.

TurboWerx offers a limited warranty on the parts against defects in material and workmanship. TurboWerx reserves the right to improve or change specifications without notice.
