Bought a 1984 RX7, has racing beat manifold but no carburetor, any good advise on new carburetor holley,webber,edelbrock what size cfm

 

hi and welcome to the forum. i can't be of much help since my only experience is with the holley. racing beat offers different kits depending on porting. for the stock port 12a, the carb is a 465cfm. i currently run a 600cfm on a streetported 4 port 13b out of an rx4. the kits are rather pricey so this really depends on what your budget is. for weber/dellorto, i've read some use 45mm and 48mm. i would guess for edelbrock would be similar to holley for size in cfm. then there's always a stock setup. you will need a min post count of 5, start with an intro in that section, to access the classifieds so that would be a good place to start. will this be a daily driver or you plan to do autox or track events? the holley doesn't suit well for hard cornering due to fuel slosh as it sits 90 degrees from how it normally sits on a V8.

 

Do you have the stock manifold or an aftermarket? If you've got the stock I'd recommend going with the stock Nikki carb and removing all of the emission stuff if you can.

 

No i got it with a racing beat manifold no carburetor. its going to be a project car, doing lots of research on holley sniper EFI

 

Sorry, I misread your first post and thought you wrote RB exhaust. If it were me I'd only put an aftermarket carb on if the internals were ported.

 

What do you suggest holley or edelbrock and has any one tried the holley sniper EFI?
