Ok so i just bought a jdm 13b, this swap is going to go in a 90 b2200 pickup, am converting the engine to carburator aswell as it gettin a full rebuild and full bridgeport...my main questions are wat can i eliminate off the engine to clean it up..can i eliminate the air pump? I seen alot of rotaries without it but not sure wat it involves...also am using t2 4 port housings...thanks guys n sorry for long post

turbo engine emissions removal.

If you are downgrading the engine to a carburetor, everything comes off. You need a 4 port carb manifold and I can't think of any stock emissions equipment that would be used. Certainly not the air pump as it's job was to feed the cats and anti-afterburn stuff.

I'd reconsider you plan though. A carbureted brigeport drives like crap. Don't let anyone else tell you different. Fine for a wide open throttle racer, absolutely terrible everywhere else.

You'll also need to pickup a 1st gen dizzy and coils to supply ignition.

then whoever is setting up your carbs isn't very proficient. it's not easy to do in some cases and greatly depends on the carburetor being used.

It also depends on the definition of "driving like crap". I'm well past the point where I can put up with things like bucking, harsh on/off throttle engagement, massive backfiring, interesting starting, etc. The bridgeport can only be tamed with a good EFI system and tuning (sadly my Microtech is now at its limit as far as to how much finesse in tuning there is left...). Two barrel carbs tend to do better as they handle the wild vacuum fluctuations better, 4 barrels seem to be terrible.

Either way, a carbureted bridgeport drives like crap compared to a properly tuned EFI bridgeport.

About the only thing that I can add with out getting a severe whomping from these three ^^^^ is to keep the carb reasonable , don't go to some big bitching thing that you will never be able to setup and tune proper keep it smaller . the little engines don't need huge carbs IMO the bigger the carb the harder to tune .
