What do I need to switch my GN to E85

[turbo tom]

I hear a lot of good things about E85 and want to switch my car to run on it. I know I have to change the fuel filter and since im going to change to bigger fuel injectors I would like to know what size injectors. Ill be going to a bigger turbo soon also so any info would be greatly appriciated. I love this site.

Check the Stickys....Depends on how hard you intend to run it and what % E85 you run!

You will need a revised FAST program or a E85 chip since the A/F ratio is MUCH different. Generally, most will need a stronger fuel pump and 12-13 volts at the fuel pump because you have to deliver 30% more fuel AND maintain safe fuel pressure (fwiw...as you pump more fuel, the pressure goes down if you have maxed out your FPR). Now we all know that you WILL turn up the boost so you will need even MORE fuel flow and pressure. Of course, the octane goes from 91-93 to 105 (for 100% E85) so that will help reduce detonation......check the stickys!!!!!
