    I apologize for my posts of late, they have a pretty limited appeal.

    Can anyone give me feedback on these two styles of Weber carb? As you know my application is a rotary, 12a stock port. Future plans are for a bridge port. Thinking 48 for both as that gives me all the carb I need for any app save a full PP.

    Thoughts?

    Ahem: TWMInduction or PierceManifolds has IDA or DCOE style EFI throttle bodies.

    This ^^^

    An IDA on a well built 13b can put you well into the 200 hp range, but with nowhere near the driveability that a 'squirt can offer...

    FTFY

    That said, I adored my 48 IDA equipped RX3 with 4 port 13B BP, it was a mild BP and made a solid 260hp, raced for 5 years without incident.

    No power until around 3000 rpm than it was like a bullet to 9000. it screamed, the IDA kept up with the fuel demands on all tracks

    I'm old, dumb, and cheap. And a bazillion years ago, I knew how to work on them. Carbs suit me just fine.

    For under a grand (carb, intake manifold, jets, venturis, and such), I can set up a carb to get 250+ hp on a rotary. It's tried and true, I can look up just about anywhere how to do it, and it's been a highly successful track combination.

    If someone has an injection system for that price and knows how to set it up for the rotary, I'm all ears.

    Thanks,

    J

    In reply to Jeff:

    Back in the late 70s and early eighties I had a '72 RX3 w/12A and stock ports (later w/mild street ports) and a 48IDA, header and a prototype Racing Beat exhaust. That muffler probably weighed 80 lbs and it was still loud. It felt like it lost a little on the very bottom end, but it's a rotary and never really spent any time at low RPMs, so no big loss. Throttle tip in was more abrupt than the stock carb, but not unmanageable. It did make me contemplate a bellcrank change or something, but I never got around to it. Aside from that, I thought it was a great combo. No experience w/DCOEs on that app.
