Hi,
I am going to fit a 6 speed G50 trans (inverted) from a 993, with a 3.6L varioram engine. I will have to use a cable shifter (from Patrick Motorsports or CableShift. California Motorsports modifies the trans for a cableshift running from the side but that is excluded for me as I am based in Europe and would have to send the trans to the US to be modified, and back to Europe). My question is if there is enough length for the long nose of the trans . I know I have to cut the trunk for the inverted trans. I have seen at the Renn... forum a car which had the bellhousing and shaft shortened at Patrick Motorsports in 2005 but they did not explain if that was necessary, or if as an alternative, the opposite side could have been shortened. CMS states that shortening the bellhousing is not recommended for G50's later than '89 due to starter compatibility issues. I guess the issue is the elimination of the guide bushing for the starter when the bellhousing is shortened, and that is not an issue for '89 and earlier cars, because High Torque Starters which do not use that bushing are available. For '90 and later cars I have not been able to find those starters. Can someone help with information on the application of the 6 speed trans from a 993 ? I am building a 914-6 GT replica and already started applying the fender flares, and modifying the engine cover with a second grille. |

I see 175 lbs listed for a boxer trans.

Thank you guys for your comments and help :
1 - I am aware of the extra weight, but I will have to live with it. I am getting reinforcing plates from Patrick MotorSports for the body, and will build a structure to support the trans, connected to the rollcage. At least I got a flywheel and clutch from Kennedy Engineering to replace the heavy parts from the 993. 2 - Eight years ago I bought the trans and engine from a 993 which had crashed, and the insurance company considered totaled. It only had 12 thousand miles and it was a bargain (just 6000USD for the engine, and 3500USD for the trans). Being in Europe it is not so easy to find a Cayman/Boxster trans (I would have to search with the words in German, in French, in Italian, etc. ...), so I am planning to stick with what I have. I have found some interesting photos at https://rennlist.com/forums/914-914-6-forum...d-in-914-a.html 3 - The G50 upside down will not bolt directly to the engine ... I was not aware of that ! I will have to think of some welding ... I have tried to contact the guy who placed the photos of his car in the above mentioned site, but so far I got no reply. 3 - Varioram too tall for the engine bay ... I will have to check that, and if necessary will have to replace the Varioram by the inlet manifolds of a 964. 4 - GARAGE or PADDOCK for this suject : I hesitated a lot between the two, but in the end I concluded that the Racers are more likely to modify their cars, and I assumed that it was the best choice to get some advice. I may consider placing this at "GARAGE" Is there a way to transfer it from PADDOCK to GARAGE, or do I have to enter the subject in GARAGE ? |
