Hello,
I’ve just rebuilt a 1971 2.2T engine, with the intention of installing it in my 914. As I understand it, it should be possible to mate the existing side-shift gearbox to the 2.2T engine by using an early flywheel, while retaining the existing 914 clutch. Is this correct? Thanks in advance |

That should be possible.
I'm running a stock 901 side-shifter behind my 3.6L /6 (Although not with a stock clutch). (IMG:style_emoticons/default/idea.gif) |

Yes, I running a 901 side shift with short gears from a 2.2 S with PMOs and Ben's headers. Love it.

Yes, that is the exact combination I have in my car. I recall that I used the 914 pressure plate and clutch, but I'd have to check.
BTW - Don't neglect the main shaft support bearing and washer that sits in the flywheel / crank area - suggest renew that and the clutch throwout bearing at the same time. Also the (nylon?) pivot bushing, as these crumble over time. - Tony |

Thanks in advance Have the same engine ,used Saches NOS pressure plate and disk way before they got rather expensive ,a very straight forward conversion IMO. The 215mm clutch handles extra h.p. no problem well over what the 2.2 T can deliver as my research indicated . Cheers . |

I think its worth so you don't have my issue and learn from it (IMG:style_emoticons/default/chair.gif) . Cheers. |
