TBI e85 conversion

[SkyHighColorado]

I am looking into switching to e85. Has anyone on here done it? I will try this kit when I get her back running for $300

Might have to do some fuel line mods.

I wouldn't recommend one of those kits.

I have not had experience converting this platform to E85 but I did convert my Saturn Redline to run the cheap race fuel.

Most cars made after 1991 are capable of running E85 with out replacing the fuel supply components. On my 06 Redline, all I really needed to do was a custom tune. I also went from 60# to 80# fuel injectors because you need approximately 30% more fuel using E85. I also converted to a Return style fuel system to give me more control over fuel pressure under vacuum and boost.

I don't know anything about the GM TBI system so I don't know if it had the capacity to provide about 30% more fuel without upgrades.

I'm interested in finding out what might need to be done on this platform. I plan on converting my 99 from the CPI to the MPI and running E85.

E85 will give you more power, but your gas mileage will go down. I don't recommend changing over, pretty much everything needs to be either replaced or removed and flushed.

E85 is great for a modded Mustang or Camaro cause of the octane level seen a few Mustang mags do the conversion was worth it, but if its just going on a daily driver thats not really modded and doesnt need more octane skip it, ya e85 is cheaper but your mpg will drop so in the end not really saving alot

Hmm good point, last summer e85 was way cheaper though. And yeah I wouldn't say my engine is modded by any means.

I am going to do it, I just decided. My research says it will all work and to expect between 5% - 15% loss in mpg's since I will be able to switch between regular gas, mix of both and 100% e85. The hq for the FFI system is in Denver, so if I have any issues I'll go talk to them. I'll let you all know if it's worth it after I get some experience with it. Planning on having her up and running by March.

Good luck! And please report back with how it is

 

[GMRedline]

Make sure to advance your timing to take advantage of the increase in octane. Your truck will feel a putzy running E85 if you don't.

Good luck.

Is there any update to this thread?

 

[SkyHighColorado]

Not yet, its actually getting quite complicated and I would be better off running a stand alone computer so for now I don't want to spend that much money on the truck. I have body work I want fixed first!
