Carb for 13b turbo
 

I'm Building a 13b Brigdeport carborator turbo. Out of a Rx7 S5 block and turbo, will a Rx7 S3 carb hold the pressure from the turbo or would i have to use a IDA or something differant??

If I was you i would just try an IDA
becouse no way an stock carb will work for an turbo
and i think s3 rx7 are only came out 12A Turbo but i don't know 100%
Hope you have an very good fuel system ready for it too
Good Luck
