I'm putting together a e85 LQ9 with ported 243s btr stage 3 cam tbss intake and of course bolt ons... the injectors I had for this set up originally are just the tbss injectors but I'm doubtful they'll be able to provide enough fuel now that I'm going with e85 over 91 due to the compression.. what size injectors would you recommend? For a fuel pump I'm going to be running the AEM380

 

I'd say go with 58-60lb/hr or 72lb/hr, either will do the job running E85.

An injector calculator is what I'm going by. I'm going to error on the side of caution and say it's making 450-500hp, so that is what I come up with.

 

Thank you for the response I was assuming the power would be 500+ but all that matters is the butt dyno lol is there a certain brand of injector youd reccomend

 

Fuel injector clinic and or Deatchwerks both offer good injectors with data for tuning.
