    Jenvey just announced a new triple throttle body targeted towards the Porsche 964. At first glance though, they look like they could be a great option for someone wanting to EFI a boxer while keeping the carb look. The cylinder spacing is even 94mm.

    They're essentially a replica of the Weber. For my car, I went with more of a BBLM / Lucas look; which I don't regret at all, but had this existed at the time, I might have gone this route.

    The manifold stud spacing seems very close, but I'm not sure it's an exact match for the BB manifolds. The manifolds I designed are for the BBi, which uses 40mm x 68mm. The Jenvey dimensions are 38mm x 65.8mm. I don't know if the BB and BBi stud placement is different. So you'd likely need custom manifolds to use these on a BBi, but maybe the BB as well.

    With this and some careful ignition planning, you could have a modern EFI Boxer that would appear period correct.

    The BB and Porsche carbs fit each other. That would be a nice upgrade on a driver for sure!
