Well, I've decided the time has come to change my sbc powered teener to a better trans axle but in doing some research, I'm not clear on a few things...I've pretty much narrowed it down to either a Boxster or Cayman 6 speed.
While I know there are gads and gads of alternatives many of which the reader will no doubt recommend, for a variety of reason I'd rather we stay on point the original post. And while your guess's are fun to read, first hand experience is far more valuable. First, I gather the Boxster S and Cayman Six speeds are essentially the same the Cayman having a higher gear set ratio. True? False? Renegade Hybrids stated the adapter they make for the Boxster is for the S six speed because their opinion is the five speed isn't robust enough to take the torque developed by a v-8. True? False? When it comes to the Boxster and the Cayman five speed, I've heard the Passat five speed is essentially the same but quite a bit less expensive. True? False? Would a sbc developing 400hp with something like 350 ft Lbs of torque have the ability to grenade the Boxster/Cayman (or Audi if true) five speed box if driven responsibly with frequent track days? Yes, no? And forgive this last question, the Audi FWD 01E trans axle six speed, what models used this trans axle and would it, could it, be used in the above noted spec engine without grenading? Thank you in advance for your input and first hand experience. |

Great timing on this thread since I have been trying to research the same upgrade for my SBC/901 combo. I may have misinterpreted some of the info about the 5 speeds above, but I called Kennedy Engineering Products today and asked what adapters they sell that would adapt a Boxster/Cayman/Audi trans to a SBC.
They make an adapter for the Boxster 5 speed and 6 speed. They are not interchangeable, but are the same price. I left my notes at work, but the adapter and flywheel are in the $850 neighborhood, and the clutch packages started at about the same price. A starter was $165. They also make an adapter kit for the Audi 01E and 01X. Edit - I didn't ask anything specific about the Cayman. Cheers, Josh |

I've heard it's quite a bit less stout though. And as I recall the Boxster and Cayman 6 speeds (and 5 I think) both share the same box but isn't the Cayman box geared higher? Can anyone step in and verify that one? |
