I think this might be the best place to post this, even though it's for a 2nd gen. I did a search, but came up with a bunch of different ideas, and I'm wondering if someone has a concrete answer.

We have a 13B 6-Port from a 1990 RX7 (S5) that we're putting in our race chassis to finish out the season (race car is an '86). Engine is completely stock, no porting done to it whatsoever. Car has RB header and full RB dual exhaust.

Car is all set up for carbed set-up with a proper fuel pump, pressure regulator, etc.

I have 2 carbs at my disposal: a 45DCOE with Racing Beat manifold (where the top half hooks on the OEM lower half), and I have a 51IDA with Racing Beat Manifold (built for our full Bridge 13B 4-port -- WAAAAAAAAAAY too big).

I would like to put the 45DCOE on the stock junkyard engine we're putting in the car while the race engine gets fixed up. I have a variety of jets and things at my disposal. The carb has 40mm chokes in it right now and a 300 needle valve (I also have a 225 at my disposal). I have F8, 11 and 16 e-tubes.

What would be a good jetting set-up for this application? Just needs to get us through a couple race events.
