I have seen many of these new turbo upgrades, but I was wondering why most people are going with Rob Becks and not the other choices?

What are the pros and cons to each or one over the other?

It would be nice if this thread could also just bring info on each in one place so people dont have to read multiple threads.

Thanks Guys

ASR are crooks.

Check the various M5 boards, very shady company.

Kind of a harsh statement.

Some issues with them around delivery of their n54 turbos but I wouldn't call them "crooks"...everyone got what they paid for in the end

They owe me close on to three thousand for a year now.

I think it was 1 or 2 people who had given ASR their M5's and thousands of dollars for a twin turno upgrade project and over a year had gone by and no work had been done. It's a crazy story if you have the time to read it, its really eye opening..

Quote from another site and who was dealing with the ASR issue:

" I have a friend locally who has expressed interest. He has first consideration but you are now second if he changes his mind.
If we get there I'll send you pics of everything with details and conditions of the M5.
All I have going for me is honesty, the rest I've been fvcked.
My thoughts are to sell the M5 as salvage. I have no idea of what or how I will find the car. I hope it is pretty much how I left it there 23 months ago. It hasn't even been covered. Someone told me, "oh yeah I saw your M5 there". "The silver one" NO! It's white just looks silver because of the 1/4" of shop dirt accummulated! But I never said anything because I was a "friend" and didn't want to make issues. Believeing all along that things/components were being developed. Yeah right!!
I also have custom built HRE 18" wheels (2) there to run DR's that I trust I'll get back?
I want all my OEM stuff back. Things that belong to me amd I've never given authorization to get rid of, sell or dispose.
I trust I'll get my M5 back just like I dropped it off in Jan. 2009 . Components from it were transferred to my black M5 but I want the OEM stuff off the black M5 for the debacle of the white M5.
Okay I'm getting worked up b/c there's so much to say. If there are ears/eyes out there, original or allies, I ask this.
1. where are the 20 pistons and 20 rods (Steve and I)? Money given for in Jan. 2009.
2. where are the developed/fabricated components, never demonstrated after 23 months?
3. where are the 4 Precision turbos (ceramic bearings) always talked about. Only see "one" turbo for over 2 yrs. Continual talk about going back and changing to "better" turbos. I spoke with Garrett people about the topic from what I had been told and was looked at like I was an idiot.
4. where are the "clutches"? Still at the "machine shop" or did they have to go back b/c there was another problem?? I called SPEC, spoke to them and felt like a fool. Wierd to be told, "we have no idea what you are talking about".
5. what has been done with all the money? Granted say it would not be the total amount but the apparent attitude is that we are suppose to pick up on the R&D costs? What R&D? Where, what, never showed us anything. We pay for the product and for all the crap we've endured there should be an even greater consideration, for being the "guinea pigs" on an apparent failed project. If we were going to make a % of "sales" (joke) then yes we pay for part of R&D.
6. I have been silent too long. Steve and I have been unrealistically tolerant and patient. WHY? Because I thought we were "friends".
All would okay if there were real concrete tangible components and progress. Even the length of time would be okay but to realize there's NOTHING?
I take it one step further. If there were components wouldn't one think they'd be shown to us? I would be proud and excited to show my customer to advances and components. So why haven't we been ever shown anything? You know.
A year ago I would be told, "do not want to post any stuff b/c am concern of others trying to copy" Sounded logical and I accepted it and agreed with it at that point but now we know don't we.

He won't communicate with me anymore. When Steve calls "and gets answer" he's told, "I'm with a customer and will call you back". Never calls back. Or "I'm remote tuning" will call back.
When Steve says I'll hold and wait, "oh no this will take a while" when talking to a customer.
Incredible he has turned his back to these customers over here.
I have been told of some things that also further upsetting.

THIS IS ALL TRUE.
Things are happening b/c being a nice guy gets you fvcked. I never said much, always accepted and trusted. What a fvckin fool and moron I was.
Steve please come in and tell more of your story.
To the aliies, talk to me if you'd like"

RD sport and ASR don't use the water lines. RB retains the stock configuration. Not sure about the Helix. Don't forget AW Motorsports also. And as I can recall, someone said ESS is working on one too.

[scottp999]

As far as I know the Rob Becks, TD Stage 2, and ASR are the only ones that are an upgrade of both wheels (compressor and turbine). Rob also includes his redesigned waste gates, and installs new actuator arms.

TDs are as well way more expensive.

ASR does not use the water lines, though they say they have good reason.

Choosing a compressor only upgrade when there is a good full upgrade is up to you.

That isn't even the start of it.

They royally screwed over two M5 owners. A matter that is far from over.

Story, pics, etc on other forums.

Helix compressor wheels have a combined 540hp worth of flow in their efficiency islands on a compressor map, the turbine wheels are clipped and the turbos come with the updated wastgates!

[Tuner1984]

I'm definitely thinking of going with the Helix Turbos when I save up some more money. I have had nothing but great experiences with Helix. Also great customer service!!

[Brey335i]

+ 1. Also wanting to see how the Heliz turbos turn out. Especially because they're a good deal

[s2k_335i]

Not too many reviews on the guys that run Helix turbo. I travel many miles but have not come across one person that has Helix turbos yet.

[sdstatestud88]

Do we know what RBs horsepower flow is in their efficiency islands?

The TD stage 2 can also be ordered with a wastegate upgrade and the new actuator arms.

Also, the installation issues that Enrita had were due to the lack of proper oil and water lines which were not provided to him at the time. They can now be ordered along with the TD turbos themselves.

I agree however that the RB upgrade is more practical as you do not need to change the oil and water lines for this, but can reuse the stock lines. Also, they're less expensive for people from the US. Performance wise, both should be identical.

Here is a link to a guy on our forum with Helix Turbos:

[s2k_335i]

it's more like an issue with the traction control than review on Helix turbos.

[scottp999]

Would like to see more helix dynos other than the pump gas one on their dyno at 15.5 psi. Any customer dynos out there with pump, pump + meth, race gas + meth?

[Fernflex]

My friend with ASR had to wait a lot to get them he almost cancelled the transaction in the credit card, after installed his car is a monster, no problems at all and the service have been great. Best dyno at 18 psi 100% offset correction on pump gas with Procede V4 was 430 in 90 degrees and humid weather.

I have another friend with helix and in jb4 map 2 with fmic, dci, catless dps and his dyno was 398wph and my car without with fbo 393whp. And he has wastegate rattle.

Forced Performance did a set of turbos for AMS. I wonder if Robert at Forced Performance will consider still doing those upgrades for other customers. I have run various FP turbos on my DSM's and Evo's over the years with great sucess. FP had some issues when they got into the Subbie world...but I've never seen anything but great things from them. Plus I know for a fact they stand behind their warantee claims.

What about EPL?
