    What’s the compression on this engine? 87 octane has more energy than 99 octane. Be sure to feed it the right fuel.

    Now we know why the fuel pump went bad, since this obviously happened before the exhaust was installed.

    3 mods I'd do since I've done them all, though I have an FD; 2 if not all 3 should apply to an rx8. I'm assuming the engines are pretty much the same but forgive me regarding any differences.
    1. Add an OMP adapter kit, From Rotary Aviation to add 2 stroke Marine oil from a separate catch can to inject oil via the engine oil injectors. This eliminates premixing and allows clean oil instead of dirty engine oil.
    2. Delete PCV system and add another catch can to keep excess engine oil out of emission system.
    3. Most importantly, add a Hydrogen Booster system!! This will, depending on system construction, significantly increase your MPG and power! Got 45 MPG in 4.6 Ltr. V8 Ford expedition with this self built system. Currently building a slightly smaller system due to limited space in my FD.

    If you cant get at least 400 miles Max on a fuel tank then your car isn't considered fuel efficient

      So what do you expect after quoting from the video? We all hear it in the video don’t need some one to repeat it 😂

  • Miss Kizmet The Mistress

    I had one of these called Roobz, she was a 231 and I don’t think I ever got 20mpg out of her 😬 With that said.. I’m off to start th’video 😂🙌🏼😂
    Edit: Nostalgia kicking in looking inside at the seats, steering wheel and at th’dials, LARGE PORTION! 😮 Hurrah! 😁😍 Oowh, Roobz y’ridiculous mare, I miss you and your whistle! Even your pathetically small starter motor and tendency to get yo’ass flooded by Greenflag employees who didn’t understand you needed your fuel relay removing in order not t’make th’issue worse when I first got you with each additional crank (and who took great offence at being educated in this 😬😂) RIP you scarlet harlot 😍 Thanks guys, this was funny as fucking HOOF! 😁👌🏼👍🏼🙌🏼😍

    i hope so, because you need to check the oil everytime you put gas in it, also the dipstick is small and deep in there so have fun burning yourself...
    its a miata with wider wheel wells and stupid rear doors and an unreliable engine that dies at 80k miles
    sad, why did they kill the rx7 :'(

    My VW Up! Did 644 miles with 13 gallons in the tank approx. Because I'm in Brazil (using shitty gasoline) so it was 1030km with 46 litres.

    Just noted that you have your old (doctored original) exhaust system. Would the spiffy new one be better or worse as regards fuel consumption running "light" footed, as you are?

  • Sandy Macpherson

    Pity you haven't got any loooong runs. Yesterday I drove 1185 klms in 12 hours dead without speeding but having to dodge 33 mtr road trains and geezers towing caravans. With petrol at $1.40 - $1.59 per litre, I'm not sure what it cost me, but I imagine the costs would be prohibitive with a rotary.

    I could probably do this. I routinely get 25-50% above EPA estimates on fuel economy on every car I get to drive long enough to learn how it handles. My current daily beater, which is high miles and lots of wear, I get an average of 32 mpg city, the EPA estimates 22 mpg highway. Automatic transmission too. My last car, the EPA estimate was 15 mpg city and I averaged about 23, but it was painful (v6 auto trans). With a rotary, I would probably get 2 mpg because I couldn't help myself.

    I don't get the "coffee makes you poop" thing everyone says. I can literally drink two pots of coffee (24 cups) and it have zero effect on my pooping. Coffee does make me pee though.

  • BatMan Tall dark and BatMan

    Dude that was so epic!!! that's awesome to know that Felix did that. because I don't think my RX8 does that, because I love to show it off, ha.. but I think I could calm down when it comes to economy wise.
