 Is anyone still enlarging the diameter of our throttle bodies, Wouldn't it be nice to add a bit of power with a little more air?? |

I believe @JamesM is running the Vanagon TB and plenum. I'd be interested in what's required to make that work. I can't find a good pic of one of those plenums, as I'd like to see what the vacuum outlet/port selection is like.
I think this is is rig. Very clean setup. But I can already see I'd probably have wiring harness issues with the way it's oriented. (IMG:http://www.914world.com/bbs2/uploads/post-5834-1576449659_thumb.jpg) |

(IMG:http://www.914world.com/bbs2/uploads/post-5834-1576449659_thumb.jpg) Throttle body is 2.1 vanagon, the plenum and runners though are 74 1.8 parts. Only modification made was using a tailpipe expander to open up the plenum to match the 50mm vanagon TB, and swapping the throttle arm from a 1.8 throttle body over to the vanagon throttle body for proper throttle cable orientation. Using the Vanagon plenum is a bit more complicated as no 914 intake runners are a direct match to it. |
