The Boxster "S" 6 speed trans, that is used with the LS3 engine. Are all of the transaxles geared differently, or all the same?
Is anyone else running the Boxster "S" 6 speed, with an LS engine? |

Ok. I called Kennedy Engineering today for you...I do not have good news. According to them, the base Boxster 5-speed adapter plate will not work with the Boxster S 6-speed. It does not matter whether or not you drilled the mounting holes.
The "kit" they sell includes everything needed to mate the 6-speed an LS engine. It costs about $2,800 + shipping. Good luck! Tony |

Tony Thanks Tony! I am still waiting for a reply back from kitcarchassis.com, if the starter I now have, will work on the 6 speed, and my current adapter plate. So far this is what I have heard back: Yes, the 5 and 6 speed use the same holes. The early 6 speed uses a couple of less holes than the 5 speed and later 6 speed but they are located in the same places. You just need the correct clutch for which ever transmission you are using. I will have to check part numbers but I think you will need a full clutch kit. |

The next statement in the post may confuse some, so......the 5 and 6 speeds use the same hole pattern if the 5 speed (Boxster) is the 012 version, and the 6 speed (Audi) is the 01E version. If I recall correctly, the 012 and the 01E use different clutch kits. They have nothing in common with the Boxster S 6 speed. Kennedy (KEP) is 5 minutes from my office. Andys |

Andys According to the guy I got the adapter plate from (kitcarchassis.com) Yes, everything is the same except the clutch. The 6-speed has a larger input shaft. I would just need the clutch kit. (Spec SP892S) Clutch, PP, TOB, and he wasn't sure about the pilot bearing?? Said that 99-04 Boxster "S" are more favorable with taller gears. That would use a Spec SP892S for a stage 2 or a SP893S for a stage 3. The S on the end indicates a sprung clutch disc. I buy my clutches from this company, http://sohiperformance.com/ |

I must be getting old... $650 for a mass production clutch and pressure plate for a street car just seems absolutely ridiculous.
Got any other options? I'm fairly confident I have the same adapter plate and flywheel for my car - Thom Ok. I called Kennedy Engineering today for you...I do not have good news.
