Thread: SR20VE+T E85/93 Comparison (Log manifold/GT3076R/NismoTronicSA)

No need for "e85 injectors." Just need to calculate for ~30% more fuel. Can also switch the injector o-rings for teflon o-rings.

Ok thanks

I might try out some e85. Kinda late in the season though. Car's going to be down for a few months. Definitely something I want to check out for next year though. Would be great for track days at the very least.

Ok so if we want to run E85 do we have to change Fuel lines ? i really want to run E85 but my only concern will be Lines and filter .. and about gas tank will it rust ? .. I have read that people have just done it and have never had a problem even after a full year of ussing E85.. Also E85 + Methanol will it be and overkill ? cause i read about the corvette guys are doing it for some reason. It sounds like a good idea has any body done that ?

From what I've read, the biggest problem may be crap in your fuel tank getting 'cleaned' out and that clogging up your fuel filter. So a fuel filter change a month after you start using E85 may be a good idea. Besides that, people don't seem to have issues w/stock fuel lines. Also, depending on your fuel system, you may need an upgrade because E85 requires about 30% more 'flow' than regular gas.

- E85 requires approximately 30% more fuel to sustain the same "boost/power/thermal/whatever" levels as gasoline (think burn characteristics)
- Stock lines are compatible with E85
- "May" need to run a proper fuel pump (most pumps nowadays are being made with E85 compatible materials and you will need the extra fuel flow as well)
- Proper Injectors
- May or may not need to keep an eye on the fuel filter (haven't heard much about this myself, but just for precaution)

If the car has been running and such and is filled up on a regular basis, "crap" in the bottom of the fuel tank/cell should not be an issue (I heard supposed horror stories of rust flaking off...........If you "common" sense it out, it's a low chance occurrence and can happen regardless of E85 or not)

Tune and smile!

You'll need to change your oil more often too.

In my experience, I let my car sit for weeks at a time, and sitting did cause my stock rubber fuel feed line to start leaking. Not sure if that is common tho. I just switched to a Goodyear PTFE rubber line.

The e85 will definitely tell you where you have soon to be leaks in your fuel system. Day after switching to e85 my sump feed to the pump started leaking. Had to put new hose and make sure it was all the way into the AN fittings.

I love the stuff so far. We will see how the dyno goes once the new manifold goes on and my turbo arrives here in a couple days.

I just went ahead and changed all my rubber fuel lines with new ones, I figured they were 20 years old so it couldn't hurt. I've read all the new rubber fuel lines are E85 compatible. I also just switched to the walbro 400lph. this was after the tune just to be safe. I love the drivability of E85, seems so much smoother and doesn't smell at all like when running pump gas!

Love e85, so far on 10psi the thing absolutely is a monster. Zero knock, pretty conservative on timing. I could probably bring in 3-5 deg more timing in boost and a/f's are on the richer side right now so there is a lot more to be had when its fully tuned. But I love it. My goal is to be 530-550whp range at under 15psi and the way it pulls now on 10psi id say its def doable.
