can i use a turbo to blow through a holley

[jimmys79rx]

ive got the holley carb on my 12a/13b and i was wondering what i would have to do to blow through it, or would i have to pressurize the whole carb,

Actually the only big worry with a turbo is that you can't do a draw through setup and get much life out of the turbo.

The guys in the carburated and old school section should know quite a bit about this too.
