Ah yes the Octagon where threads go to die. There are at least two threads about DAW turbos, probably more. No idea why they were sent there.
I tried to visit the owner of DAW and he would not even agree to meet me. Guy is sketchy AF. All of the cast turbos are basically coming out of the same place. Amazing how DAW had the 'exclusive' 4th gen GC VTT turbos 1 month later for sale. Not the 1st time DAW has refused their warranty mind you. You know the 3 year warranty which is an absolute joke just like their stolen warranty language.
I swear the N54 platform is plagued by sketchy people, sketchy tuners, and shitty vendors. Anyone who refuses to let you meet them, makes you pay in an odd way with no chance of refund, or refuses to give you their legal business name and address is highly suspect and you are likely setting yourself up to get fucked. Like DocVu making you pay with friends and family to launder the money to his gf who does not pay taxes is a perfect example. Or JPworks, or DAW or 15 other people I could name off the top of my head.
They are generally more expensive than the more commonly used PTE turbos on the n54 platform. Same with EFRs. They also require 2 coolant lines on top of the 2 oil lines that only the PTE and others require. I am honestly surprised more people/manifolds are not designed around the BW lines of turbos. Granted they are generally larger in physical size but MUCH more affordable. If you are just doing highway pulls the advantage of a water cooled CHRA or DBB CHRA is minimal at best. As the n54 is not great on the track(in many cases) the need of a watercooled CHRA is basically nill. That being said Garret probably has the best reputation as a turbo supplier in the aftermarket vehicle space.
