I hear ya. I just purchesed Creamiz's turbos he had now trying to find a shop to install them, or deciding on the HPF single turbo for 6k

[jayzF30]

for all that effort on their end they better be worth the time in terms of power...how much more power do you think they will make over the RB turbos?

RB turbos are also water cooled and have an upgraded wastegate that should not rattle at all either. And they have an upgraded compressor and turbine wheel as well, although I don't know whether both are similar in size to the ASR turbos here.

@OP: Nice job, looks great. Have fun with it and let us know how it drives!

Just to clear things up, the gen1 ASR hybrid upgrade (that I still have, an almost 3-year old option for our N54's) is somewhat similar to the RB hybrid upgrade (different quality of parts, etc) except for the cooling method (as you said, RB retain stock water/oil cooling; ASR gen1 is only oil cooled). ASR made a glory run of 540wheel and 530trq with race/meth. The highest RB numbers I know of is just over 500wheel, correct me if I'm wrong.

The gen2 upgrade shown in this thread will be awesome and what I will also be getting quite soon. Initially the gen1 upgrade was only oil cooled because it uses a ceramic bb-chra. Gen2 goes back to water/oil cooling for numerous reasons but one that sticks out now is that customer's (domestic and overseas, even some race teams) feedback from the gen1 upgrade said they didn't want to wait to shut off the car after a spirited drive, they liked that the water pump would still run with the engine off.

The gen2 upgrade also retains the gen1 turbine wheel but instead of a cast compressor wheel you get a billet one. As the OP explained, blade length was increased just over 6mm's due to a smaller hub diameter (due to being billet) and they also modified the inducer/exducer. This will be good for an estimated 50+wheel. Time will tell obviously but abid has told me on multiple occasions that he expects 600 (maybe even more) wheel on race+meth.

How do these compare to the TD Stage II Turbos?

[alr335xi]

They have been out for a while. These are what Shiv ran for a couple of years until recently since he went to a single set up. The current ASR twins have a new billet wheel design and actuators from Forge. I agreed to wait for them as I was not in a hurry. My old setup made around 420 to the wheels on stock turbos. The car pulled like a freight train already.

[alr335xi]

Parts will be in tomorrow. Car should be on the road by Wednesday. Dyno Saturday.

unfortunately TD turbos have not got much air time. main reason afaik is the price. TD, RB and ASR hybrids are all similar in some parts. enrita is the only public guy running TD hyrbids afaik and he's fixing a major boost leak and will be getting some better results/data to share with everyone.

[import36]

looking forward to your results OP.....turbos look great!

Hello BMW tax.

Just to clarify, the turbo kit lists for $5,995.00. I purchased a bunch of parts from Vishnu at that time with the turbos so I might of saved a little. When I mentioned $7,000.00 for the turbos, I included a little for install. Getting the turbos installed is not an easy task at all. You will pay anywhere from $1,200.00 to $2,500.00 for an xi.

I just wanted to clarify that these are the ASR Stage I turbos and not the Stage II turbos with the new Billet Compressor wheel. As I was informed by ASR their new billet wheel is in production as we speak and first couple of sets will be installed by next week or so. Oddjob is correct in the fact that ASR's turbos have been out for a few years already. I chose to wait the 6 months for mine since they were in the development of their new water-cooled CHRA setup and new piston style actuator which is what I preferred to have. Although, I'm not sure why Oddjob has referred to them as hybrids since they are a complete Garret GT CHRA upgrade for both stages. Maybe Oddjob could help shed some light on the subject.

As far as how to compare them to the TD turbo upgrades, as Oddjob said that's difficult to do since there really hasn't been much information on their setup or dyno's other than enrita that I've see. Although, I did see were enrita's TD Turbo upgrades didn't bolt right up and required modifying by cutting or grinding some parts to make them fit. The ASR's fit just like factory turbos with all their retrofit water and oil lines and bolted right up to my ETS intercooler and intake piping.

Thanks for all of the information. I think it's best to put out a summary when you are done (maybe all on the first post so people don't have to search all the pages), so everyone in the community can do good comparisons of the available options.

The summary, could include:

1) pricing. You mentioned 5995. Does that include install parts, if so, is there a list of what is provided? I think your install numbers are pretty spot on, some may get it done for a little less than the range you mention, but they are lucky.

2) results. It would be nice to results from a local dyno shop on 93 octane, 93 octane +meth. I say nice, because I have never dyno'd since my turbo upgrade so I understand some people just don't have the desire to do it.

If you can give details on what meth nozzle(s) you run, etc. it would be great.

When people start getting the stage II (billet, larger compressor wheel), would love to see some independent customer comments and dynos showing the 550-600 whp range.

The main restriction will be the stock housings and manifold design?

gotcha. i had figured you got the stage 2 because I saw the new chra with the water cooling ports. as far as why i refer to it as a hybrid upgrade, this is because just like TD and RB, ASR uses the stock exhaust manifold and modifies it to fit the upgraded chra.

i currently run 2 meth nozzles. one is post-compressor, pre-intercooler and small, an M3. the other is the main one in the charge pipe near the BOV. that one's an M12 or 14.

i also cannot wait to upgrade. i will dyno when i can and hope to match what ASR will eventually put down which i'm also at the edge of my seat for.

Yes, it includes all parts needed for install. They don't provide new manifold gaskets but they are about $1 each and can be source from any local dealer. You get new oil lines, oil distribution block (this attaches to the block after you remove your stock one) and waters lines. Look back thru this post and see the supplied pictures labeled pre-install. They should be early in this post.

2) results. It would be nice to results from a local dyno shop on 93 octane, 93 octane +meth. I say nice, because I have never dyno'd since my turbo upgrade so I understand some people just don't have the desire to do it.

I will provide dyno sheets from my "local dyno shop" when done. I should be there this weekend. I will only provide 93 + meth results. My car is currently tuned for meth and I am not chancing on reduced octane

I am running the Vishnu 2 nozzle PWM meth kit w/ charge pipe.

[alr335xi]

One other key point I wanted to mention in regards to the ASR turbo setup is the major difference in a/r ratio of the stock turbine housing vs. ASR's. If you look at the pictures attached, you'll see how ASR's manifold is cut completely in half on the turbine side so they can weld their adapter flange on. Once the turbine housing is cut on the CNC, as shown in the previous pictures I posted, the other half is left completely wide open to accept their weld on adapter flange. ASR explained that their main reason for doing this was to increase the a/r ratio of the turbine housing to support the increased exhaust flow volume which would reduce egt's and back pressure. ASR also explained that typically increasing a/r ratio increases lag, but since their turbine wheel flows so efficiently they mathematically chose the correct a/r to match turbine speed & flow. From what I've seen of the RB's they do not do this process. It looks like they weld a v-band flange to accept their larger CHRA and cut the manifold for the larger turbine wheel, but that's all. Given the fact that ASR's turbine side of their manifold is modified to a larger a/r ratio and their turbine wheel is bigger, that would explain a lot as to why their turbos maintain full boost and power to the rev limiter as compared to others.

Might have missed it are the new stage 2 still BB going from just oil to both oil and water now?

The TD stage 2 bolted right on. Oil and water lines were not supplied since i did not want to wait another month or two so i got them custom fabbed.
Only issue my back turbo was slightly out of clock so the piping went too close to the front turbo manifold which ended up causing a leak of the rubber hose over time. This has been fixed now.
No issues with the turbos. Seems a well engineered hybrid and sturdy. Turbine is slightly smaller than RBs so they will make less power probably.
To expensive though since done in the UK.

Yes, both Stage 1 and Stage 2 are both oil and water. I have the new Stage 1 and it is both. The kits come with all lines needed. Abid @ ASR Engineering's 135i N54 made 538 WHP and 530WTQ on dynojet with Stage 1!!! Check out ASR Engineering on you tube. You will see Abid's 135i. He has the standing mile record for a N54 at 181mph!

Good deal, glad they worked out. There are many good options out there!! So far I am happy with the ASR. The issue we have is self inflicted! I broke the stock water inlet pipe during install. New one coming tomorrow.

What I meant to ask was if the new design still uses ball bearings?
