Good morning. Have been contemplating pivoting to a Boxster S trans. I see the G86 is a viable option but I also see 6 speed G87 Boxster 6 speeds online for sale. Are they both viable options for the 914 conversion and an LS motor.

Thanks Brett

There's lots of information on the G86 out a lot less info on the G87. Renegade uses and recommends the G86 though. The G87 has a lower (higher numerically) final drive ratio. In case you haven't seen these links yet...

Maybe I'm wrong but I thought the Renegade LS/6-speed kit only worked with the G86-20. That's what I have, that's what Cracker has, it's a proven transaxle for pretty big hp and the gearing works well.
Tony's car sees nearly 170 and his LS7 puts down 520 at the wheels. No trans issues to date.

Thank you for the response guys. I looked on eBay for G86. Any other venues you found to have a good source of G86’s when you were looking?

So are there versions with LSD? I see the Info link above says they weren't shipped from the factory with LSD?

No factory LSD, as far as I know. A couple aftermarket versions. That's one of the upgrades I'm looking at now. Does your 930 trans have one? Maybe all of them did, I'm just not that familiar.
