So i recently had my engine street ported by Chris at Banzai Racing, and i was wondering if i could get some different oppinions on the best carburetor set up to use including amount of fuel pressure etc.
I will be running mixed gas as well, and have not decided on an exhaust system yet. Any input would be much appreciated.

Some info about what kind of car this is would help. I'm assuming 1st gen? Because otherwise, it would be crazy to downgrade the EFI system.

yes it is a 1984 GSL-SE. everything is stock except ignition wires and the engine porting. otherwise im trying to find the best way to get it running at its best with a relatively low budget. I still have all of the parts for the original EFI set up if thats still the best route

What has you thinking about carbureting? As Aaron had mentioned... It would be crazy to downgrade.

Sticking with the EFI system is the best bet. The stock manifold is a dynamic effect manifold, meaning that it is tuned to work with the intake pulses and uses that effect to "naturally supercharge" the engine. It actually generates about 2 PSI of air pressure at the intake ports. Swapping to a carb would bring about all the issues of a carb (never quite tuned, AFRs are only approximate, no closed loop, temperature and pressure sensitivity) plus remove the tuned intake.

Mmkay those are good points.. But that's the whole reason why I joined this site haha.
Is there any way to eliminate all of the emission controls while still using the stock ecu? or is that even a good idea? I haven't done anything except tear everyth.ing out to have it painted. So since I'm starting from the ground up I wanna do it right

You can remove the emissions controls but aside from removing the cats, there won't be any gains. See the 1st gen FAQ for info. Don't remove the idle valve or cold start thermowax.
