Hello everyone,

A friend and I are building a 12A powered Miata for endurance racing and are looking at installing an EFI system. We are going to use the Megasquirt system but have questions about which type of TB to use for best performance.

Any suggestions or theories between a 4 barrel or 2 barrel weber type TB?

Any help would be appreciated.

Thanks

 

welcome.

personally, I would go 4-barrel-style. it's easier to control the ports.
