Andrew, N55 diverter valve is integrated into the housing, no? Vargas claims that this will utilize a stock housing so your question is a good one. VTT, will this make use of the stock diverter?

This tells me it is time to start taking pre-orders so I can get a list together as I am only able to do about 10 of these on the first run due to the cost and availability of cores. The intro price for these is going to $3499, for this you get a genuine Garrett Dual Ball bearing CHRA with a custom reverse rotation GTX compressor wheel, custom reverse rotation Garrett turbine wheel, and all the needed lines to convert it over. The turbine and compressor housings are staying the same so all those connections will be plug and play. There of course are other supporting mods needed, as well as a tune. We will be working with PTF as well as Terry on the initial tune as the Cobb N55 software should be ready by the time we are, and BT will have the capabilities to tune these as well. I just had a customer email me and ask if it will compatible with the Procede, that is yet to be seen, but I do not see what Shiv cant tune for these. I will take a total of 5 intro price orders this batch and I will be requiring a 50% deposit to reserve your spot( if the interest is very high, I may add more intro price spots). Spots will be reserved in order of deposit taken and will be shipped in the same order. If interested please email me directly at Tony@vargasturbo.com and we can get everything set up. As always thanks everyone for the support.

Warranty? I'm looking post warranty for some serious fun! The 2011 N55 owners will be post warranty in a year, and then the fun begins!

To void warranty or not to void that is the question. I'm really tempted. Can I get some dynos?

They are just getting ready to begin testing so there are no dynos to be had yet. Patience...

Hurry up already, I want to see some numbers and then I am pulling the trigger. Do I need an LSD now if I add the turbo upgrade on an Xdrive? Will jb4 regulate what is needed for the bigger turbo? Fmic is a must I guess since that is one mod I am missing.

FMIC and oil cooler I'd say. I wonder how an LSD would behave on an AWD vs RWD, and if it would be needed at all.

Exactly! The stock diverter is tiny and its already sounding like it has some compressor surge at high boost.

Questions:

1.Are you using the stock diverter valve? Im already getting codes that's it stuck open at times when running high boost in a long gear.

2. Is your estimate of 500whp on pump gas, meth or e85?

A 500 whp 2 series would be a dream
Andrew I just saw this. The stock diverter is electronically controlled, and intergrated in the housing, speaking with Cobb they said they were having issues with it as well and are hoping to find a way around it and just use an aftermarket recirc BOV. This is just growing pains, once hardware like this is available the parts like aftermarket BOV's etc tend to follow suit rather quickly. Our estimate is based off this exact turbo set-up putting down 550+ WHP on different motors, the fuels used vary. This turbo will support a little less then that as it is running through the stock housings so 500 is a perfectly doable number, how we get there, tuning, fuel, etc remains to be seen. Once we get it on a car and testing things will become more clear quickly.

Cool thanks for the response.

I see bog warner has some larger twin scrolls with integrated diverters. I wonder if they can be swapped with ours with some machine work to the housing. .

This might sound dumb but how do you have a price set if you don't know what hardware is needed?

? I know exactly what hardware is needed on my end to provide a turbo that supports the WHP we are claiming. Thats exactly what we are selling you. Complimenting mods to take advantage of them are always the responsibility of the customer. Things such as fuel upgrades, intercoolers, charge pipesm BOV's etc.

This should be a great step forward in performance for the N55.

I think a lot of people are very skeptical about the turbo upgrade because physical numbers have not been posted yet along with drivability, reliability and tuning.

I would be interested in something like this, but personally will hold out until I see solid numbers and how the turbo and tuning will work out.

Please continue to keep us updated with pictures, videos, dyno graphs and any additional information that you can provide.

Best of luck with the remaining r&d and sales. Thank you for all the time and money you have invested in this product for our engine.

Thanks man I appreciate it. Its going to rely 100% on the tuning. Turbos aren't magic, you are putting as wheel in the exhaust stream to turn another wheel connected by a shaft to force more air into the motor. On these cars to take advantage of that extra air all falls back on the tuner and the ability to access what he needs to in the DME to do this. Pretty simple when you look at it that way.

What's with reliability? How many miles can you drive and enjoy with these turbos? 20k, 50k, 100k...

I'm guessing that the diverter on this engine is electronic due to valvetronic governing - no throttle plate in use under normal driving conditions so no pressure differential when you back off the throttle = conventional BOV doesn't work. Surely someone will come up with an uprated electronic option.
