Looking to upgrade my Turbos
Hello everyone. New to the forum. I bought a 2009 135i with front turbo leaking. My goal is about 400-450whp. Most of the info on turbos I found is about 1-2 years old. Was wondering if the info I read is accurate/valid today.
Vargas OEM supports up to 500 and has a nice price but from what I have read its a hit or miss if you have issues with them. Is this still true? RB turbo was pretty close in price but it sounds like customer service has gone down hill? Pure stage 1 turbo cost more then the other 2 but haven't heard of any issues? Anything else I would look at? Thanks |

Id stick with Pure or RB and my stg2 rb's got me 400 and change to the wheels on just pump gas with alot left on the table. Im sure pures are similar in similar size.
I emailed Pure, RB and VTT when i was ready to buy mine. Felt most comfortable talking with Rob at RB. So i ordered from him. |

Yes RB 2's td03. Rob is straight up good guy I trust him. He pushes for more turbo than needed so its easy power and is safe and reliable.
I put down alot more power when i run my e50 tune. But eth is a pain to get here. And i only dyno'ed with pump. |

I was (presumably) a bit over 500whp on stock turbos.
Just about 100,000 miles on them at over 24psi. Over 400 drag passes, numerous lapping days, ice racing, street and daily duty. When I sold them they still felt tight and didn't look to be leaking. Only issue was rear actuator was leaking. I really want to say that if you do inlets/outlets and keep an eye on WGDC you really don't have to worry much about stocks. Be smart about how you lean on them and you can get some really good power. The big limitation is they choke if you want RPM. I never really pushed over 6,000 RPM. No power there, no reason to go there. That might have been a big help? For the cost of the stock CHRA's that Rob (and I want to say Tony has them too, if you ask) I'd really go that route. Far as anything upgraded, Id' go straight to a TD04, far better flow, keep the backpressure down and EGT's in check. And I hate to even say it buy, those ebay 17/19t's seem to be not entirely horrible. |

So Rob will sell the Chra's you just got to ask? I heard people talk about that before but never seen them on his website. I don't plan on getting to crazy right now. Maybe once she is paid off and I get bored I'll think about TD04. |

I had talked to Rob and as of right now he has no cores to build for the 135i. I guess people are not returning their cores in a timely fashion. So If I did order it would be up in the air to when I would get them. Almost temped to just try the VTT chras.

I would just go single turbo, after everything I've done spent for turbo's inlets outlets and such I regret not spending the extra couple of hundreds for a single. Speedtech makes a well built kit for a decent price or you can go with Doc Race.
If you add up new RB's or Pure's plus inlets and outlets you're already in the $3.8k range, these kits start at $4.2K for ball bearing turbos, which are way more reliable than any hybrid turbo kit. And any maintenance after install is way easier with singles. Plus with any hybrid you'll want to replace your oil and coolant feed and drain lines which add another 3-5 hundred dollars. Most important is the oil drain lines as reusing the old ones especially if they're old, can cause the oil not to drain properly and cause turbo smoking/failure. Additionally you'll have to upgrade your PCV system to also prevent over pressurization of the crankcase which also can cause the turbos to not drain properly. Yes installation is a bit more difficult, but if you're having a shop do it, it shouldn't be much more considering installing inlets on our cars are a pain and add to install time. Tuning on single are also a bit different, but if you contact a contact a tuner before hand they can walk you through the process and have a base map for you. You'll need a pro tune regardless of hybrid or single. Long story short I'm going single this year, I've got a bunch of suspension parts awaiting install first tho.

Temping price on the vargas but not liking what I seen on reliability and how the owner acts.
I decided to order some chras from RB with upgraded billets. Going to order a wastegate repair kit here soon. |

I did look into those and after doing a lot of thinking and taking aspirin for the headache I decided to save some money for now and get the RB Chras with upgraded billet blades. It should be here by the end of the week. I already got my turbo's taken apart which was pretty easy. Only thing I need to do if get the bushing out for the wastegate. Once I get the car paid off I might look into single turbo either from speedtech or Doc racing.

Throw the turbine housings in the freezer overnight. Then heat around the flapper. Might expand a little better and not be so difficult to remove. Reverse for putting bushing back in, freeze them. |

I used a 9/16 bolt that was about 6" long. Ran a 9/16 nut at the top followed by 2 washers then a 20mm socket to go round the bushing hat. Took another 9/16 nut and grinned down the edges to make it some what round. Threaded that in from the bottom. Help the bolt still with one wrench and turned the top nut until the bushing was out. How ever for the second turbo bushing I sprayed PB blaster on the bushing from the inside and let it sit for an hour or so and that one came out way easier. I did plan on putting the new bushing in the freezer and the housing in the oven. |
