Alright i just got another rex shell and im putting a carbed 13b that i found in it. Problem is im a turbo fuel injected guy on my other rex so i dont know diddly on carbed sevens. The motor has twin side draft carbs and headers. I tried searching the forum but couldnt find what i needed as to the basics on getting it running ive heard people say i can run my fuel pump and ive heard people say to downgrade to a 12a pump and such. I can put the motor in and hook up the intake and exhaust no problem. What im asking you guys is what exactly do i need for a fuel setup (pump, regulator and lines) and ignition. the shell is a turbo2 shell so thats the harness im using for battery powers at least. I have a walbro 255 and an aeromotive fpr. Is that over kill? and how much fuel pressure should i run? any help would be great please teach a newer school rotary guy some old school tricks. Thanks.

The side draft Webers use a little less than the downdraft 48s. Try 2 1/2 to 3 pounds max.
Protect the carbs from header heat, lest the fuel boil.

thanks you guys are awesome. Any suggestions on how to use my turbo2 harness to mount coils and run it to the distributor or did i nail it on the head right there? cause im not sure if it will even work do i run seperate coils and run the plug wires to the distributor? there are these two 4 spade male connectors at the base of the distributor is that where i run power? Now that i got the fuel system sorted i only need to know how to wire up the igniton system to my t2 harness and im good. Any more help greatly appreciated.

LIDFIS for the ignition.
I ran the FC leading coil directly from the leading ignitor on the dist, then ran the plug wires right to the plugs, No dist cap involved. Trailing I ran 1 aftermarket coil off the trailing ignitor, then through the dist cap like normal.
The car sounded and ran like the stock FC.
