I went with a journal bearing, .63, and a full 3" vband welded on. Its going on my 1.8t TT with a stroked 2008cc 10:1 motor. With what i have seen, i should see 20psi at 4k. The spool between the dbb and journal is minimum and since mine wont see above 22-24psi on 93, journal bearing will be fine since it comes standard with 360 race bearings. If i was planning on keeping it in the 30+ psi range, dbb would of been more ideal. Setup should make around 450whp on 22psi but we will see. Dont see a reason to run a .82 unless you plan on revving higher and taking the turbo to its limits more often. 400rpms of added lag is about right between the 2 housings

Just ordered the 6057 
. Mike convinced me that this would be a better option for me given that I don't want to max the turbo out. I'm still on a stock block and will maybe try to push it to 550-600whp max.
According to Mike the 6057, 7 blade design, will spool similar to the 5857, 6 blade design, but will make more power at the same boost unless you run crazy boost (40+psi) where the 5857 will make a little more peak power.

From our experience the 7 blade designs usually make more power lb for lb up until a certain boost level where the 6 blade design takes over at the higher pressure ratios.. We are using the 7 blade 6057 on a car here that is spooling 30psi at 4500rpm and its Journal bearing.. So if BB picks up anything this thing will be a lightning fast turbo..

And you say the 6057 and 5857 are very similar up until a certain pressure, what is that roughly, are we talking like high 20s or at like 35psi? I run 28psi daily on 93 and meth. I don't know anything about Precision turbos but have been looking in to a new turbo and I emailed Michael Bacon and he wrote back that the 5857 had a better wheel design and would make more power than the 6057 and then also spool sooner so this new billet wheel turbo had me interested.
I currently have a Garrett Gt3076r .63 a/r on my 1.8t A4 that is now 2 liter and has Aeb head and cams so pretty similar to the jetta USP Motorsports put together, only better. I am wondering if it is worth it to sell my turbo and get the 5857 journal bearing for my car or if I should be looking at something else, I could most likely get $1000 for mine so it would be a direct swap with no money lost, just dont know if it is worth it or not. I want to make another ~50-75whp on the same boost and timing settings (or as close as possible) but don't want to run a Gt35r or have anymore lag (over 2-300rpm, I currently see 28psi at 4200rpm in 3rd ) and like I said I don't know much about other turbos out of the Garrett family so has been hard trying to figure out what would be a happy medium between a 3076r and a 35r.

What a/r turbine housing is used spooling at 4500?

So could the 5857 with the .63 be run in the 450hp on 93 for someone who would like to use a little more throttle around town with allowing for possible larger gains latter on? Or would the 6057 be the better choice?

My car should be in the 425fwhp range on ~21psi with a crappy flowing stock head and cams. you should have no issues reaching 450awhp with more psi and decent cams
