Mildly Modified E85 Z32-TT

Legend’s Z32-TT has basic mods considering how many new parts are available for the Z32.  He was looking for more power safely (until his big build) and with the better availability of ethanol fuel in our area we went ahead and converted the Z to run ethanol.

The Z has the following parts\mods:

  • Stock Longblock
  • Stock Turbos
  • Stock Exhaust Manifolds
  • SZ 2.5″ Super Split Down Pipes
  • SZ 2.5″ Test Pipes
  • SZ 2.5″ Dual Tip Catback
  • Nismo 740cc Fuel Injectors
  • SZ Flywheel
  • SZ Max 6-Puck Clutch
  • Stillen Intercoolers
  • Stock Intercooler & Inlet Piping
  • Selin Translator & JWT Dual POP
  • Blitz sbc-iD Spec-R Boost Controller




We made a baseline pull on 91 octane fuel (green run), and switched over to E85.  We’re very lucky that both our stations carry ethanol that ranges from 80-84% ethanol content throughout the year.   In any case, we made a pull on E85 without touching the boost controller or timing.  We only obviously had to change the fueling.  This is the difference ethanol makes just changing over on this particular Z.  This is partly due to the amazing cooling effect of the fuel.  43 torque was gained at 4500 RPMs and almost 30 whp.  Peak power was up 20 whp and 35 torque.


Here’s the final tune for E85.  Impressive power for the little amount of modifications this Z has.  444 whp and 487 torque!

    impressive numbers.
    what is needed to run the e85 ?? do you need to change fuel lines and injector o-rings at all?

  2. Safety wise, its best to run fuel lines that are teflon (not rubber). O-rings that are generic rubber can have issues. I’ve seen great results with genuine Nissan o-rings holding up. Supply wise, you need 30% more fuel delivery than standard gasoline.

    Awesome! What kind of timing did it run up top at that boost?



  5. It is highly recommend to change all the fuel lines. Word is that the latest Nissan fuel hose is bio fuel compatible. For those upgrading to a dual pump setup and top feed rails like the BDEs, I recommend PTFE lines.

    Was this done with the stock fuel pump? I am finding a lot of mixed information on the pump. A lot say its good to ~700HP but I don’t know if that’s using E85 or some other fuel.
