what carb mods do i need to do to run on a blow-through setup? (using holley 600) will the stock fuel pump work (79 rx7) ? this motor is stock port

 

Im sure you need to do something, but I dont know what.

No the fuel pump wont work...At all.

Do a SEARCH. Theres LOTS of people out there doing this.

PS - Welcome to the forum .

EDIT: Ok, maybe not lots of people, but lots of information .

 

From what I've read with a holley there is not too much modification necessary. You'll have to change the float to a solid type so the pressure doesn't crush it!

Here is a great link with a ton of turbo/super charger carb info!

Enjoy!
