Finally got VICS hooked up and a slightly better tune on there. Timing isn't too agressive IMO.
VICS made quite a difference in spool. Apparently I had it stuck in the open position before, so no "long runner" low end torque. I hit 10PSI @ about 3800-4000 now. Still not good, but better.
Logs will come eventually when I stop being ghey.

It would not be a good upgrade, but it still holds as a good brand new turbo for roughly the price of a rebuild & balance.
So far I have about 4 autox's, 1 HPDE, and 1500 street miles on it. Running strong, just miss my low end! lol

Of all the days not to have a T3 manifold so I could pick up Brain's chinacharger. I don't think there's a good cheap alternative to the 2650r (Nissan ones pop up now and then but I keep missing them, argh). There's a 2554r locally for cheap-ish that would be a bit nicer for spool but nothing on the top end.

what did you end up using for turbo feed?
I am ordering this turbo right now for my build, just curious what route you took for oil feed, enjuku mentions to use -3an line only, but everything seems difficult to find in -3an. Im thinking of just running -4an and using a restrictor such as:

would you run .060, .045 or . 030
also, are these the correct fittings for water and drain?

I would like to order the correct parts the first time and help would would be great.

Bros! if anyone is looking for a 2871 china charger I'm selling one! It's the godspeed one many people have had good results from. Comes with a bunch of random fittings, no idea if they will work though.

Few thousand miles on this turbo now. I started to hear a faint noise today that could either be the turbo or a coupler loose... It is only audible in higher RPM's and when it reaches full boost (Only 10psi for me). Hopefully its just a coupler or something else stupid. If this thing dies I'll probably throw a used garrett on it

No problems or issues for me yet. Then again I've driven about 3 miles since November. The car has ms3 now with ebc so I'll be tuning up to 16-18psi And find out where she runs out of breath

I haven't gotten to drive the car much yet. My wideband was giving me **** so I am in the middle of replacing it...Then I need to retune.
I did do one autox on Memorial day and it was great. I had NO issues falling off boost even with the shitty spool of this turbo. I am still at the wastegate pressure of 10 PSI.
More to come next week I hope

Well, time has told ...
Blew the turbo today. Side to side shaft play and bad noises when entering boost. It happened during a track day.
Street miles : 5000
track days: 8-10 20 min sessions
boost:10-15 street, 10 track
oil: 15/40 Rotella.
Feed: -3 an
bov: shitty greddy type rs
Track oil Temps got to 250 during a session. I know the 15/40 isn't great for high oil temps so I'll be changing to another oil. That may have had something to do with this.
Oh well. Time to buy a real turbo. At least I cought it before it blew into pieces and went into my motor.

Yeah I checked shaft play last week and had none. I checked last night when I got home and had no front to back but Was able to find side to side. It was stiff though which explains why I was able to drive home and not have an issue. It was only when I pushed pretty good that I was able to move side to side.
