Hello,

I have a Porsche 914 and I'm converting the drive train to an LS1/boxster S 6 speed manual transaxle (2000-2004). I have the adapter built by KEP and a nice clutch setup they provided too. I'm in the market for a used gearbox and want to know what to look for when examining them. I've read through the forums and gleaned as much info as I could about the subject. Here's a summary of what I already know. Talked to Roger at CMS and he recommended getting one with the lowest mileage possible. I've read about the second gear problems and the sealed bearing issue, finger test. Looks like there's a second gear detent modification you can make. Seems its best to use OEM fluid in the thing. Cables and trans mounts can create issues.

What can I do when examining a gearbox?

Any help would be much appreciated!

Thankyou

Newbie Bill
