Porsche 986/987 Stage 3 Turbo Kit

The TPC Racing Cayman/Boxster Turbo Kit comes with many optional upgrades to generate more power, and a more visceral driving experience. With all of the optional upgrades included, the TPC Racing 987.1 Cayman/Boxster Stage3 Turbo Kit offers 500HP with the OEM engine package.

TPC Racing Stage3 includes:

  • TPC Racing Stage3 Turbo Kit
  • Stainless Steel Race Headers(cat/no-cat available)
  • TPC Racing Routine Programming & Dongle
  • Greddy ProfecB SpecII Electronic Boost Controller
  • Compressor Bypass Valve Kit
The addition of a set of stainless steel race headers helps improve exhaust flow to the turbocharger, improving overall responsivness.

With the addition of the Greddy boost controller, comes multiple benefits. First, is the obvious advantage of being able to adjust boost on the fly. But secondly, the boost controller has an added, passive benefit. The electric solenoid that controls the boost acts to preload the wastegate, preventing it from venting slightly under partial boost. This ensures that even at the standard boost level, the wastegate doesn't vent until it reaches full pressure. The result is much better throttle response and a more power in the low-mid range rpms!

The TPC Racing Routine Programming & Dongle provides the driver with a handheld switch that allows the driver to quickly and easily change performance map/settings to best suit the situation. What does this mean? Say you are out at the track, and you can hear the call of the of the MS109 or C16. Just plug the TPC Routine Programming Dongle into your OBDII port, and switch from standard mapping(conservative) to a more aggressive mapping, that will allow you to take advantage of the full potential of the race fuel youhave available to you. But the Routine Programming Dongle provides for more possibilities than just track related. Say you live in an area where you have access to different fuel(crossing state lines), your Routine Dongle could allow you to switch between a 91octane and 93octane tune. Or it can be programmed with a built in valet mode. So many possibilities with one little switch!

Finally, the Stage3 includes a Compressor Bypass Valve Kit. This kit is built up around an Porsche GT2 bypass valve, and will help keep revs up between shifts, again providing even better throttle response.

With the full TPC Racing Cayman/Boxster Stage3 Turbo Kit, drivers can enjoy one of the fastest and most flexible Cayman/Boxster Turbos the road has ever seen.
