915 conversion
Hey guys. Anyone know what's involved in replacing 915 with G50?
Is there a conversion kit available instead of purchasing each component? Has anyone on the board done this with 'hard learned' suggestions? I have the newer trans. Thanks all.... |

it's a fair bit of work -- try googling "convert 915 to g50" and you'll see a few threads -- here's one as an example For those interested in a 915 to G50 conversion

I did a G50 in my 930, you have a few options.
Shorten the bell housing, find a G50 donor shell for the torsion tube, or notch the torsion tube and do coil over suspension. All of which are fairly pricy. You will need this from a G50 for the swap G50 trans G50 clutch slave G50 peddle cluster with master cylinder G50 brake reservoir G50 throw out bearing G50 flywheel and Pressure plate. I chose to buy a G50 wreck and sell off all the extra parts to break even.

Not trying to derail your question, but if you're looking into this, might also be worth it to price out some of the nice, comprehensive WEVO shift kits for the 915.
Might be able to get shift action that's more to your liking without the cash and hassle of the conversion. |

Unless you are going with high HP, the 915 is a good box.
I'm up in the 400HP range at the rear wheels. If you decide to go another route, PM me the details on the G50

Thanks everyone for your comments.
The 915 was Professionally rebuilt last year. Billet. LSD. JWEST. etc... My question was to appreciate what others have experienced in way of difficulty, $$ and time. You've given me something to think about. Thanks again. |

A G50 is much more difficult/expensive to rebuild than a 915 isn't it?

The best advice is if you really think you need a G-50 is sell you 915 equipped car and get a newer 911. You will spend a LOT of money, and make the car not original which can hurt future resale even though a G-50 is considered an upgrade by many.

Both can be done by a competent mechanic, I've done both. The 915 is a lot easier.
