I have a 12a BP in a 80 corolla. I was wondering what size carb would be best for this setup. I don't know to much about a rotary, but I am learning. Also what fuel pump would be best. It has a racing beat intake and header

dont put anything larger than a 600cfm holley on it. i have a 12a bridgeport as well. i researched it an a 48 ida webber or a 600cfm carb is what is best. I went or another way though, using a factory spec book we machined the factory carb to allow it to flow better. We machined out the primary venturies 3 tenths of an inch and the secondaries were machined just over a tenth of an inch. we took out the jets and drilled them out to allow them to flow more fuel. haven't tuned it completely yet or dyno'd but were are looking for about 180+ rwhp. i'll post actual numbers this spring when it hits the dyno

holley is a good choice, 48ida would work too. holley is going to be a little more streetable

Thans guys. Also what size jets would be good to? https://www.nopistons.com/forums/pub...1047683329.gif
