Hey guys so I pulled the trigger on some pure stage 1 turbos today! I know it doesn't sound like much of an upgrade but I daily this car so I wanted reliable turbos, but also a bit of an upgrade. I'm going through Matt at znm auto but I found some information on the here http://topgearsolutions.com/pure-n54...turbo-upgrade/
I plan on coupling these with precision raceworks relocation inlets.
I have a few questions regarding fueling.
I plan on just using pump 93 oct. But I do not have an LPFP upgrade yet, should I go with a stage 1 pump or stage 2? I really don't have access to E85, but maybe further in the future methanol could happen
Anyways what kind of power do you think I could put down on a daily use map?
If there is enough interest I may do a dyno right now before the upgrade.
If you can not see mod list, I'm FBO with a full 3.5 inch exhaust

Those Pure Stage 1 turbos are tasty. I talked to guy with an 2011 335i, n55 motor, and he was making about 475-500hp (FBO I believe)

That's good to hear! Hopefully that translates over to the n54, all I want is to get near 430whp on 93 with inlets

I'd recommend stage 2, most guys that go with 1 end up going with 2 in our experience. So just go to 2.

Methanol can be added at any time.

On 93 Pump you should be about to get ~500WHP

If you change a few things on your mods you can get very near 430WHP on stock turbo's. I'd start with a different intake and intercooler. After that it will come down to a custom tune.

Thanks for the input! Yeah I was really thinking about it, but then I remembered I have 143k on the engine. If it was younger I definitely would!
Regarding the intake, I have precision raceworks inlets that will be going on with them so hopefully that will ease them up top! I suppose I should step up to the HD core soon, but to be honest I don't really do many consecutive pulls, data logs will definitely let me know the full story after the install.

Keep us posted on how it goes!

[arhoads335i]

So I talked with PURE and asked them about the compressor specs. This is what they told me "We don't give out our PURE spec compressor wheel dimensions."
Oh well, I was more interested in the wastegates being fully upgraded like their stage 2's and they confirmed that they are!

Congrats OP!!

[Supra2k6]

bump congrats OP, Anyone got some numbers for pure stage 1's FBO N54?

most people install tune and enjoy it's hard to get into a dyno so i't understandable.

[arhoads335i]

Yeah I've been looking around for info on them but it seems that they are somewhat new. I imagine it's like vtt stage 1s with billet wheels, hopefully more reliable also! I just hope I don't have any more wastegate rattles

Went with ZNM as well, if i'm able to hit 450whp+ with custom tube on inlets on 93 i'd be happy.

Top gear solutions is saying 500 and that would be just fine with me.

Awesome! same turbos? Hell if that's what i'll make with a custom tune on 93 I may not have zero pints on my licence for long

[arhoads335i]

hopefully they can get put on in 2 weeks!
Parts have been adding up to help get the most out of these
1. Pure stage 1 turbos
2. Precision Race works relocation inlets
3. VRSF outlets
Looking for a stage 2 LPFP to finish it all off

[viny741]

hey OP any update on the results? looking to do the same upgraded turbos, how do you like?

[arhoads335i]

Hey, They are working out great with inlets and outlets. Car is awesome, but I am now selling it just because I want a V8 again, if your car is somewhat stock maybe we could do a trade with some cash on your end. Would make it easier for me to trade it in for something

[Dmak]

Op. Hows does the pure stage 1 pull at top end compare to stock twin??

[arhoads335i]

feels like a different car up top but that might be mostly due to inlets.
