1990 turbo rx7

I ordered a stock mazda engine. my old engines out and new one ready to be put in, waitin incase i need bigger injectors. i have intake, full rb turbo back exhaust and fcd. what fuel mods do i need so i wont blow my engine?

thanks.

 

Walbro fuel pump should be good enough for intake and turbo back exhaust. That and rewire it. Don't think you need bigger secondaries until you upgrade your turbo.
