• The N54 finally comes into its own - Vargas Turbo Tech Stage 3 N54 (335/135) twin turbocharger upgrade sets new N54 horsepower record with 693 wheel dyno

      Congratulations are in order to Vargas Turbo Tech as well as Cobb tuning and ProTuning Freaks for raising the bar as to what the BMW N54 inline-6 twin turbo motor is capable of. There are two platform records here the first of which it is important to note was achieved without methanol injection. There are certain tuners on the N54 platform that mask their ability to upgrade and control the stock fueling system and any fueling issues are "solved" by dumping in a ton of methanol.

      Well, with no meth and the cars own fuel system (with High Pressure Fuel Pump tweaks courtesy of Vargas Turbo Tech) responsible for all the fueling 673 wheel horsepower was achieved in STD correction on a Dynojet. That is a record for horsepower on the platform without methanol injection and was done with a blend of MS109 fuel and 93 octane.

      Meth injection was then added and the figures rose to 693 wheel horsepower. If more time was available for the parties involved including Josh at Cobb as well as Jake and Dzeeno at ProTuning Freaks the 700 wheel barrier likely would have been crossed. This will happen sooner rather than later now but this is still a major milestone and a new era the N54 is entering. The motor is finally starting to mature and although it is not on a comparable power level yet with the top BMW aftermarket options this is a huge step step forward for a platform that spent considerable time in limbo due to fueling and tuning issues.

      It must be satisfying for all involved especially Vargas Turbo who was doubted by many early on due to being a fresh entrant on the N54 tuning scene with many fanboys blindly following another tuner providing a turbo upgrade. Vargas Turbo Tech, Cobb, and PTF have surprisingly quickly surpassed the results from a competing turbo kit that uses a single turbo setup and have done so without relying on meth injection band-aids. A true fueling upgrade is here as well as a turbo upgrade making some serious power and setting the standard.

      Congratulations and much respect to all the parties involved, dyno graphs and videos are below.

        I dont know how many god damn times i can say im not trying to compare the 2 im just trying to show that now that these graphs are out it looks like (not a vishnu) single may be a better option. Regardless this is a big step in the n54 community and i applaud everyone involved in making this happen!Click here to enlarge

        I explained how it isn't. It has nothing in common with a 2JZ other than being an inline-6 and turbocharged. That's it. Move on.
        I hate to bust your balls here. But I was out cruising around tonight with my best friend, and we were discussing the new vargas results and future potential etc etc When I showed him the new dyno graph and said they still had tons of fueling left his response was this, verbatim..."wow looks like your N54 is about to become the new 2JZ" I will follow that with this...He built, and drives a Supra that makes 1100+whp @44psi. So there we have it, from the horses mouth. Haha

        I would seriously lay bets they tuned it down in the midrange because .. It's already useless in 1-2 and maybe even half of 3... Want to add 200whp more halfway up? Sure it makes for a good dyno queen, but it makes for a terrible everything else unless you have warm slicks or dr's or something, and a godly right foot..

        not to mention, the n54 dyno was done on a midrange fuel mix, with (therefore) retarded timing, less mid boost, less less less... This is NOT indicative of what the stage 3 can do AT BEST.

        i'd also bet the stock rods would give up before the stage 3's run out of puff?.. Not to mention the stock compression ratio limiting :p


        ed: and @Sticky , i dont think anyone is saying it's mechanically identical or similar to the 2jz, they're saying it's just as easy/makes similar power from the factory tuned, similar gains with similar mods in general etc. etc.. But more importantly, it's more like 'what the 2jz would possibly have been more like if it were made in the late 2000's instead of the early 90's

        2jz trollery aside, now it's settled, i have no choice other than to make myself a big single setup -_-, just to keep up :p

        and it was complicated and expensive enough as it was *glare* haha

        Question to Dzenno and Terry. For auto, is it possible to keep the TQ range between 450 to 500tq?

        Tq can be limited any way you like. Just matter of a map switch.

        In terms of spool we havent touched optimizing it yet. There was no time for it but we already tested some tweaks early on in our previous tuning and I know there is more spool left in it. So much left in it if the motor will hold as we have plenty of fuel. Tony's also got some ideas on improving the manifolds further for production kits which will also be a win!

        Wow. Just saw this and I'm speechless. That's some ridiculous power on a stock block engine. Congrats!!

        Well, not really. There is this equation:

        Power (hp) = (Torque(Nm) x RPM) / 5252

        So you can't keep the torque low at all RPMs and make big power.

        He said ou can limit torque not that you can make it infinitely haha ie. save transmission >>> big power... 450-500nm at 7000rpm would be GOOD still lol (600-660hp and a dead.flat.(tq)curve.

        what he means (as i got it) is you can ramp as aggressively as you want all the way to 450-500 (or 400 or 350 whatever) and peg that to redline by altering boost/timing/fuel etc as the revs rise.

        Now your thinking! There are usually a couple on 1 addicts forum for sale for a little less but yea, the limited build really inflates their pricing...how much better would the world be if we could all easily have bought a 1m? Ughhh. I looked for one and gave up. It's just not worth the premium.

        Your better off buying someone's low mileage, lightly modded 135 or 335, ideally one with suspension upgrades, LSD, and a few bolt ons. There are usually a couple nice ones for sale from time to time. A 135, 6mt, with m suspension and a vtt stg3 would be a absolute killer....

        Most of the price i can attribute comes to the cost of the bodykit

        to take a 135i and swap parts (suspension, front kit, custom rear guards, battery tray and exhaust... Oh and LSD) gets daaamn close to the cost of the 1m... At least half the cost is in those rear guards alone hahaha, let alone the slightly slightly slightly nicer interior (moot point if you want to racecar).. All up for the body would be $10k at a guess

        you're 100% correct from a value for money perspective though

        You do understand these turbos flow enough air for ~900hp. Maybe you should compare apples to apples before making assumptions. I'd wait until you see some of the smaller GT twins. Because you might think a 'single is a better option', but physics disagrees with you. Click here to enlarge

        I understand, I think what annoys people is the market price of the 1m isn't dropping due to how rare it is. LM is better off building a 135 with m suspension and no body kit...

        N54 = 2JZ, 2JZ = N54 and so forth who gives a $#@!...I don't understand why peeps get so passionate about that comparison. Does it really affect anyone in the end? Absolutely not...

        Great work guys!

        For those looking for a comparison, look at either the new maximumpsi turbo e46 m or a ICS stage one s5x.

        Seems like the spool comes on very late. Any way to get it to spool faster? S52 guys seem to get single Gt4094's to spool faster.
