I do all the fuel system stuff on these cars! Let me know if you needed any questions answered still. I see you guys were discussing it in the thread here.

But just to clarify... injectors and retune are all thats needed for sure. a fuel pump is a maybe for NA... i wouldnt do it unless i started to see fuel pressure drop.

You could use both E85 and 93 octane but you would have to tune 2 maps and use the map switching feature to switch over when you change fuels since the 370z does not currently have any flex fuel capability options.

But then again, nobody really knows at this point if there is much gain to be found in it. Hopefully someone will try it out soon and answer that question.

from what ive seen e85 always adds power on any car with a tune. it always just comes down to price though. for me (where im at parts wise), if what you say is true (no pump needed), then 1000cc ID injectors for like $700 for 10-15hp is worth it! 15hp might be a stretch but ive seen others with 10hp no problem.

the seals do worry me though. if they arent Vitron? then E85 will eat it. older cars get "the black sludge" where E eats everything!! i dont think you can tell this on a 370 though since we dont have a return fuel system. on older cars or return system cars its really easy to see as your sock will be solid black with tar, or it wont.

im getting a tune soon with the ported everything then again later with E and injectors and possibly fuel pump. like everything on a Z just sit back and wait a while haha.

PS...how hard is it to pull the lower manifold? can i leave the fuel rails attached to the car or do i have to pull it out of the way and relieve the pressure in the lines?
