hi guys! I want to upgrade my turbo, im FBO, mhd stage 2 plus on 93 octane, cant afford ps2, and I dont have access to e85, and not planning using meth, wich stage 1 turbo would be the best for my car? 335I xdrive pwg

Pure has a clipped turbine which might allow it to make a little more power than the others but there isn't much in it.

I'd probably get a new VTT out of those.

They all do about the same, either way a good upgrade for the pwg. Been loving my setup, so much more power above 4k rpms.

Wich one did you buy?

[Marlinman]

Pure all the way in my opinion. I'd also save money for the PS2.

I concur!!

PS1 touches turbine side? Care to elaborate?

I hope he meant PS2,because that turbine wheel is bigger and clipped.

If that's what he meant, it'd be very misleading as it's a STG1 turbo comparison thread.

I'm trying to help him out for making the gaff! But you're 100% right my dude! No question.

[bradsm87]

Nope definitely referring to Stg1.

Clipping gives a tiny bit extra top-end flow at the cost of turbine efficiency. It's nowhere near as good as putting in a larger turbine wheel.

It's frustrating that there is such a large size (and price) gap between Stg1 and Stg2 N55 turbos at the moment. The market desperately needs something in between and preferably with a better turbine blade profile than the generic Chinese small hub 9-blade turbines that Pure use.

There is little you can do to turbine without modifying turbine housing.

Once you touch turbine housing, STG2 it is. There is nothing in between STG1 and 2.

BTW, quite a bold statement of you that Pure uses China made turbine. Source of info?

The whole "Stage" number naming is just silly. I want a mild turbine size upgrade (including housing machining of course) with a mild compressor size upgrade, both somewhere around half way between stock EWG and PS2 would be great.

Of course it's from China. I have no problem with that. There aren't enough choices of reverse rotation turbines around that size to leave any other choice I suspect. What I don't like is that they use the very distinctive and un-mistakeable generic Chinese designed 9-blade small hub turbine which is known to be very inefficient. These turbine manufacturers should just stick to what they know and copy the big players who have spent millions in R&D. A Garrett-style wheel would be much, much better.

Any pics of a pure stag 1 turbine wheel being clipped and how did you verify that the pure stag 1 turbine wheel is made in China? Not saying no but some positive verification would help answer both questions.

I never said anything about where PS1 turbines are made. I would assume they clip and re-use ones from core returns but they may be new.

Pics of clipped turbine and mention of modified turbine wheel right here:

I assumed right here you were talking about the pure stag 1 turbine wheel which I think is the stock BW turbine wheel. Or were you talking about the pure stag 2 turbine wheel? You did infact mention Chinese made or am I confused?

Referring to PS2.

SteamSpeed's turbine looks good but too big for my needs.

And yes I verified what you said about the stag 1 wheel being modified or rather I will assume clipped. Thanks

I still say best turbo kit made is speed tech with the efr tubos but then that changes the whole stock appearance which is a no no for some guys.

I think vtt uses Garrett’s can anyone confirm? Heard they also have been band from this sight.

Tony@VTT has some best idea in the industry, using Garrett ball bearing CHRA and stock turbo housing with hybrid wheels. But devil is always in the execution. His best idea didn't convey to performance, it doesn't spool faster than PS2 and has arguably less top end. The worst part is, quality is a nightmare. Nobody other than cheap N54 guys buy VTT anymore.

I wish Pure Turbo pick up VTT idea and makes a DBB PS2, improving turbo response. Though market doesn't seems to want swallow high cost of Garrett CHRA.

Someone is already complaining PS2 is expensive...Ridiculous to say the least.:

I can see paying 1400.00 or a little more for the turbo upgrade but the killer is the price they are charging to do whatever they do to the manifold,plus you have to give them yours to replace the one they give you. Yhey are making a killing! But is is what it is. When they charge 2300.00 or less I guess I will be all in. would be nice if they just sold the PS2 turbo without the mani But maybe they are afraid people will screw it up if the posting of the turbine wheel side is not cut right.

Ehhh Sean maybe youre right!!
