    Thank you for acknowledging that it's not sufficient to simply throw on bigger turbos (or turbo) then point and shoot.

    Nice update. Kit looks to be coming together pretty quickly!

    Nice progress being made here. Vargas will definitely be on my short list when the stockers go.

    Thought about making 5 bolt cast downpipes? Probably would help with tolerances a bit better..

    You are going to make me spend way to much money on my car... Keep updating us, this is awesome!! I cant wait to see results of these turbos and hopefully they're not to laggy.

    Well, its not that close. If we are going 5 bolt, which we are we are just going to have SS downpipes made. The cost of having DP's cast will drive the price way up. Were trying to keep this kit affordable for you guys.

    The turbo options I have announced for the kit have well established HP numbers they can support. This means SUPPORT, what each individual will actually see if a different story, based on upgrades, tune, etc, etc. But we will be doing our best to have a base tune ready for purchase right out of the gate so you can get up and running pretty easily. We will see what, if any tuning bugs we run into. But we plan on getting this prototype in the hands of a good tuner as soon as its ready to go.

    2013 is going to be great and this time next year we will be working out transmission and engine internals to push it even further !

    Im uber jealous of some kid with a decent paycheck picking up a used N54 with the mod bug in 2015 lmao

    i just want to comment on how much bigger they are, sticking out what looks like roughly in line with the engine mount, the OE turbos are eaily half the size tops :O

    Tony I wish you would stop this, you make me want to put the money towards the Stage III and not on the Stag II. Click here to enlarge

    Keep up the good work, I may change my mind!!

    It's definitely nice that more vendors are producing turbos for the N54. Looks good Tony Click here to enlarge

    So far we don't really know what the limit of the N54 bottom end is, but I'd guess that a set of forged pistons with a bit lower compression would be a good measure.

    The thing with these larger turbo upgrades is lag. Everyone including myself looks at Shiv's dyno and laughs because his peak HP lasts, what, 500 RPM? He's hitting redline at peak HP, not to mention he's not hitting full boost till like 5k RPMs. That's only 2500 RPMs at peak boost. The way to take advantage of this is more RPMs. This means springs and retainers and it means upgraded connecting rods. That ST would be a whole different animal revving out to at least 8500. That'd give you 3500 RPM at peak boost as opposed to 2500 RPMs. The point is, even with this TT upgrade, you're not taking advantage of the turbos efficiency range without some more serious upgrades to the N54. Driving my first big turbo car I have witnessed this first hand now. You can't have huge power and no lag. If you want to counter lag you move your RPM band right or you get more displacement to get the turbo to spool faster. Since i don't expect any stroker motors coming out any time soon, someone really needs to start thinking about putting some pistons, rods, springs and retainers in the car.

    bigdnno,
    I just saw this post. This is EXACTLY what i was getting at with the thread I just started and you already replied to. Big turbo cars are a drag on the street. Like most on this board, I like a quick car but I don't think that is typically the primary reason people buy BMWs.

    The problem isn't the turbo size, it's the tuning. He was limiting boost in the midrange/mid high rev range to keep TQ down. And if @dzenno's car is any indicator, it seems to be able to take a pretty serious amount of tq in the midrange, which should allow one to run a much more normal boost curve. Now, I'm not saying that with a different approach that one will see a 62mm turbo full spooling at 2500 (that said, a video he posted seemed to make about 1 bar at 3100-3200). But when one isn't limiting throughout the rev range and runs a flatter boost curve, the power curve is going to look very different.

    For people that do not know or feel like looking it up. 1 bar is 14.5 PSI. The fight with turbo lag is one that is nothing new. In theory these highly efficient GTX twins should offer quicker spool over a big single. In practice we really wont know til we have it running on a N54 because its never been done.

    How big are the I.D.s of those primaries? Maybe it's just the pictures but they look a little larger than I expected. Are ID roughly the same size as the exhaust port on the head?

    Either way, looks like great progress is being made. Good work Tony V!
