Another vote for RB or Pure. As far as I know, the are the only two companies that machine, assemble, and balance their turbos here in the US...AND have a well known reputation for turning out quality turbos.

All of the other "china" turbos...DAW, Vargas, Frankenturbo, ebay, etc, etc....are partially or entirely machined, assembled, and balanced (not sure to what spec) overseas, and although some people have luck with them, most don't.

RB, or Pure are the only options if you want reliable aftermarket turbos.

Pure stage 2 hiflows or hydra 650/800's , would be my picks.

Although considered a smaller stage 2 when put up against the 'hyped' offerings from DAW / VTT , chinas and others , pure stage 2s consistently produce not only dyno numbers at 25psi but, also track times and terminal speeds to back them up. Mine have ran 10s @131mph 24psi. Currently do 28psi duties on E85

Just remember , these stage 2s can end a stock engines life , so not only do you need to lop off the torque in the tune but, also ensure all the supporting mods are there. Starting with tyres and drive train, fueling etc.

I already have FBO with stage 2 LPFP 6MT , so my e85 limit is around 50-60% in honesty, how much HP/ torque should I start to worry about the engine… I don't race the car everyday but if I do I only roll race and it's also my daily car. And I also keep maintenance up to date.

If you are going to run an E40/E50 mix...your HPFP is going to run out of fuel flow around 550-575hp with good turbos. That's a "safe" level of power that shouldn't hurt anything.

If you want more power than that, you're going to have to step up to a PI setup....and then you can get well up into the mid/high 600hp range.

You need to figure out what type of horse power level you want to reach.

When you start to approach 575+ HP, the idea of upgraded coils, HPFP, LPFP stage 3, transmissions and the like get more and more real.

RB 2's are rated at 475-525hp / $2099

RB 2+ are rated at 525-575hp / $2399

Are RB turbos under rated? Probably….

I'd choose between those two, if you are looking to maximize what you currently have without having to upgrade coils, HPFP's etc…

I'm in USA ( if that makes a difference) but as I was looking into the turbos they ask if my 335 is LHD or RHD…

Now I honestly think it means "Left or right hand drive"

But as I search, I seen some people say it's the difference in turbos

_N54 · 11-26-2021, 11:55 PM

I have the RB Game Finisher turbos with the standard flow 17T TD04. These turbos are awesome. I don't think the N54 needs larger than 17T turbos when sticking to twins.

You are correct. LHD = left hand drive. It does make a difference, because the turbos are oriented differently on an RHD car.

Yes...they are underated. Rob told me that my RB TWO's should be making close to 575 on an E40 mix and 27psi boost. Of course the harder you push them, the less life you get out of them.....like anything else.

On 93 at 25psi they should be right at 500hp.

how big of a difference is the throttle response/ lag on the GF 17t vs stock twins? these are looking to be my next mod.

BSM n54iS · 11-27-2021, 06:18 PM

I'm still in between RB ones or oem billets

It's not that big of a lag. Full boost hits at 3000 rpm and once boost hits you'll be ripping through your tires. If anything this is better for the engine and internals since boost comes on a bit later. It's a badass pair of twins and you won't regret going with the Game Finishers.

As said above RB or Pure. My vote would be the RB GFs as they should have more headroom than the pure while being of equal quality.

Stay the hell away from VTT, Franken, DAW, etc. I base the on the horror stories that have accompanied these companies. VTT being the worst of the bunch. Better off burning you money.

mashimarho · 11-28-2021, 05:15 PM

If you want out of the box reliability, Pure Turbos have been the best.

I was the same. I chose the billets because I didn't want to upgrade my LPFP to a stage 2 walboro 450. I also didn't want to mess around with a custom tune.

Oh wow 500 whp no ethanol? What other mods you have? That's my goal no ethanol.

Just the standard FBO bolt-on stuff, RB TWO's, and a good custom tune making 25psi.

Reliability is not solely dependant on the brand of the turbo.
Get the most reliable turbo, push it over its recommended limit, and it'll fail.

I recommend you first set your HP goals and then research which options within that range are the most highly rated.

mike_o · 11-29-2021, 10:55 AM

I've purchased a set of (new) Pure St. 2 for my N54 335is, but the shop installing them now ran into an overboost issue. The factory wastegate adjustment is too tight and the whole shebang is overboosting like hell. I've read about the issue also in the 1-series forum.

Now the shop is going to pull the turbos out again (argh)

Sounds familiar to anybody?
