Want to put a Borla EFI on 502/502 with 850 Holley. Any experience out there? George from Rochester

Wow George, I had to Google "Borla EFI" on this one! I knew Borla as a name in exhaust, but had no idea that they had ventured into the induction arena, too. The EFI arena is changing so fast it's hard to keep up.

Welcome to CHR, and I hope that you enjoy your stay here. I hope that you'll continue to post about your EFI experiences. I've been through a lot with Edelbrock's ProFlo XT, and I really like the flexibility of being able to program spark and fuel across the entire rpm range, but I don't know Borla.

I am with RS on this,.......had no idea they were in the EFI either. A few things I can tell you about going to EFI from a carb is you must have an electric pump either in the tank or on the frame. Have to have a return line for the fuel back to tank. And it is a good idea to put a gauge inline to show pressure which you can regulate.
I helped 2 friends put EFI on their rides, one was a FAST and the other a Holley. Also give yourself a good day to get everything done and then take for a ride.

Thanks. Will be putting an Aeromotive phantom in tank fuel pump with a post pump filter.
Will be using a pressure gauge and return line
Probably need to change out the big mechanical distributor because of room and use either oval and rectangular gaskets (or a special gasket available through Hilborn) to provide the necessary seal between oval heads and rectangular intake manifold..Need a O2 sensor in exhaust manifold. Will be using the FAST 2.0
