Obviously the center section is stock, you can't change that out. I am talking about the wheels. It is also possible they are Blouch wheels, but not as likely.

I have a vague recollection of reading similar just before Vargas released the Stage 2 dual ball bearing turbo for N55.

Also keep in mind, at 400 WHP the stock turbo is basically completely maxed out. For comparison sake Garrett rates their 53mm turbine wheel (same size as the stock turbine with their cast 60mm compressor at only 290 BHP.

You jump up to the 53.85 turbine and the GTX wheels and you have the GTX2867 which has a bigger turbine than the stock unit and a similar compressor wheel to the stage 1 and you get a BHP rating of 475, that is in native garrett housings which are much larger and more free flowing than the stock housings housing are. We used a turbo that is rated at 640 BHP expecting it to see 500-550 WHP with the smaller housings due to the efficient DI motor.

The stock turbo is able to make 400 WHP or 440BHP with such a small turbo also due it being such a efficient DI motor. Without upping the turbine size and just putting a bigger comp wheel, its going to be very hard to get much more power out of these things, flowing more up top is usually a by product of bigger A/R's and turbine wheels, not as much compressor wheels.

Compressor wheels can increase the efficiency of the turbo and usually make the same air at lower shaft speeds which will help increase life, etc. I would be very curious to see if the stage 1 would provide any increases over stock as the turbine wheel size is basically maxed out already at current levels. But you never know until you try. Interested in seeing dynos.

Good info there. Thanks.

Hi guys

Saw the announcement from Motiv about a month ago about their new 'big turbo' kit for the n55. Wrote them an email, got no response, wrote to them on Facebook where Jake from Motiv responded quite fast, he told me to write an email which I did. They never got back to me, so wrote to them on facebook again - he got back again.. I could actually bore by repeating this again, but I think you get the patern, has any of you been lucky enough to buy from them?

They don't seem to come back to me, eventhough I'm REALLY interested in their new kit for the N55 ..

Sorry for my poor english - it's my second language.

Any update on the XDRIVE e92 n55 big turbo kits? 😅 I still can’t find any e92 n55 top mount options for AWD
