I was thinking maybe a Harley 40mm carb might work?
I figure a motorcycle type carb and be used in place of the throttle body? I have a few suby ej22 engines and thought i would fool around with carburation and with using stock ecu/fi too. http://www.randakksblog.com/single-carb-conversions/ Attached image(s)

Would work like a Pinto carb on a T4 motor... (IMG:style_emoticons/default/barf.gif)

QUOTE(Mike Bellis @ May 28 2016, 12:46 PM)  Exactly - why would you go carb when FI is the real solution?? (IMG:style_emoticons/default/blink.gif) |

I plan to use a suby engine and trans and its FI in my 1975 car. but i have an extra engine and thought it would interesting to see what a single carb and megajolt can do on a ej22. I am not expecting a carb to be better or even very competitive to FI but the engine should run somewhat decently as does a type4 with single carb does.

I'm afraid you'd be getting yourself into quite a lot of work just to achieve mediocrity. Carbs work, of course, but a single carb with long unheated runners isn't usually a very good idea. So if you're going to build the MegaJolt why not take it a step further, keep it F.I. and just build a full Megasquirt? No fabrication that way, it's almost plug-and-play, and since you wouldn't need to buy a carb and adapt it the cost should probably be about the same. But if you just HAVE to have carbs then why not two?

Stock TB is 60mm or so right?
Sounds like a bunch of time for half the HP. |

at work I have 2 ej22's under my desk ($100 each). I have one more in my 1990 legacy 5spd awd parts car ($475) there that has at least one cylinder of bad compression, that I will pull engine and trans this week and get on a stand to start putting stock FI on it. and I have an almost driveable 1990 legacy awd auto ($250).
I went on a binge buying streak of legacy's and ej22 recently. about to delve into FIing them, one at a time. Attached thumbnail(s)  Attached image(s)
