    Bottom line, the N54 still hasn'thit the limitations of the stock motor components or stock compression, so why (besides peace of mind) change anything?
    This is a big one, but room to grow is what comes to mind for me.

    I think you're putting far too much emphasis on some peak figures fit for bragging rights. When customers are out on the streets daily driving and running at the strip at those power levels we'll revisit. I like your optimism but don't share it.

    Alright, so I'm pretty new to the n54 scene, had my car for a month now (09' e92, le mans blue or w/e they call it, 39k miles 6at) and finishing off FBO this weekend (thank you ETS!). I did a lot of research before purchasing, and am still researching turbo upgrade kits and what issues/weaknesses the car might have that I may need to upgrade (fuel delivery for example, clutch in 6MT I know, but I have AT so no worries there). Or is there? That is one of my questions.

    1) approximately what kind of power can one expect to push through the n54 motor and trans before needing any upgrades? I've heard 700? If so, how come only a handful pushing close to that seem to exist?

    450Whp on stock frame turbo's, Transmissions are known to start slipping here.


    2) what kind of motor upgrades would be needed to push say 800,900, or even a 1000 HP through this car? (Please include trans)

    Rod's / Pistons full build. Look at my boring and sleeving thread.


    3) I have only seen a couple people ever use nitrous on the n54, how come? Isn't this motor capable of holding extreme temperatures? Or at least higher than average running temps?

    Lack of fueling options, would need to make a multi stage system.

    4) what is the current most powerful n54? I believe Vargas holds record for most powerful stock motor at 723hp or something like that, what about non stock motor?

    725whp VTT stage 3's

    5) other parts of concern even launching FBO with 400hp, what about drive/half shaft?

    Nope you're good on stock frame turbo's, brake boost the $#@! out of it and have fun.


    Thanks in advance, I feel like n54 has huge potential, and many seem to say it does, but if most powerful n54 is only 700hp, I'm not that impressed, for about $9k, yeah impressed, but if thats all its got, then what? Click here to enlarge

    Op - you did research and didn't find that the AT is a huge limiting factor in going for big power with the n54? Where did you research?

    If your going for big power, you'll want a 6mt to start with. I'd say you'll see some nicely built, upgraded turbo cars by the end of this year. It seems there are a few getting built right now.

    I'm flat out amazed at what the n54 can do in stock form.

    To make that much power on either of those motors requires a new fuel system and a way to control it (alphabet soup or ECU upgrades plus sensors). It'd also be a good idea to upgrade the IM and cams if you want to extend the powerband on the 2jz (it would not have the same powerband as the N54 due to slower spooling -- would need to extend the rpm limit).

    Don't get mad, but Tony set the qualifiers here; and he has a point. Considering one can slap on some parts and only need a flash tune and a better fuel pump to make >700whp is pretty impressive for such a tiny engine.

    Until we see a Vargas Stage 3 run & beat an 625/650 BHP supercharged E9x M3, the bolt-on supercharged M3 is still a better performance car for stock motors.

    Yes. Did you see the link I posted? Dousn't matter, it's still a stock motor that made 1000+whp.

    Also, the S65 is still king. +1 Benzy.

    What do you mean no? It can't be the stock intake as the plastic manifold isn't designed for boost. Other than that, yes.

    Perhaps you need to read? There is not a 2jz making >700whp on the stock fuel system. The stock 555cc injectors will only flow enough for about 500whp on pure 93. Past that point you better upgrade or you're just a ticking time bomb. And the stock 2JZ-GTE fuel rail sucks, it's side-feed and doesn't flow very well; making an upgraded fuel rail necessary as well. Good luck controlling that without a standalone ECU.

    Not stock fuel either.

    FWIW, when I say stock fuel I don't mean a fuel pump; that's pretty much a given for any platform. But MOST cars shooting for >700whp need a new fuel rail, fuel injectors, and FPR at the least plus the tuning to handle it. (on the 2jz, the alphabet soup only goes so far, it will still drive like $#@! -- you need a standalone ECU).

    Like I said, Tony set the qualifiers and you all are whiffing.

    It's still stock INTERNALS, that was the whole point. No need to be so hostile.

    Exactly. You can't handicap a car because it doesn't come with direct injection that necessitates different/larger injectors due to the pressure at which fuel needs to be injected and the injection window. Different fuel setups not apples to apples.

    I think it's more of a side project for them that they work on whenever it doesn't feel like they are pressing for it at all.

    Well this sure spun out of control fast. But to be clear, I stand by what I said. Stock motor, stock injectors, stock fuel lines, etc etc 700+ WHP very impressive. Stock motor, full aftermarket fuel system and stand alone ECU. Not nearly as much.
