I have a 2006 Evo9 with TBE, FMIC, 272cams, ARP headstuds, O2 housing, cone air filter. I am looking at converting to E85 and need some recommendations for what fuel pump and what size injectors I need. My goal is to see how much power I can make on the stock turbo. This said I am not looking to ever go any bigger than the stock turbo so I don't need a pump and injectors that will support 500-600whp. I just want to know what pump and injectors I need to make the most out of my stock turbo. Any advice would be greatly appreciated.

 

I believe your standard walbro 255hp and 950 - 1050 injectors would serve you well.

 

What speedtriple said.

255LPH Walbro drop-in fuel pump and 1000cc injectors will outflow your stock turbo no matter what boost you push it to.

 

When you switch, be prepared to change spark plugs to a smaller gap and if your changing the pump, it's usually standard to use a new strainer as well. The E85 cleaned all the gunk and my gas tank and clogged my strainer. The car had rough idles and start-ups (especially in the cold) until i changed those.

 

Im not rtying hijack this thread.....BUT.....will a fuel regulator and or a larger fuel pump and a fuel rail help things along?
would installing any of these parts make any sense?
thanks

 

^^^Not needed until you reach the limits of your stock turbo

Stock regulator & fuel rail & RC1000 injectors will serve an E85 conversion quite well

 

Turbo capable of doing the goal, supporting mods, double pumper, 1450s, good tuner call it a day.
