Default picking out a new turbo

So my engine rebuild is almost done after one of my valves disintegrated on the highway. It now has all forged internals, 3 angle valve job ported 84mm bore and 9.5:1CR. Over the past year I've built my own kit trackdog racing fmic, water injection, 2.5" full exhaust, tial wg, turbosmart bov, ms, jgs manifold et cetra.
Well a few days ago I checked out the turbo i bought used off a nissan guy I know 8 months ago and theres alot more shaft play than i remember so ran oil through it at maybe ~2psi and it leaked at the compressor blade so I'm guessing the seals are bad.
I'm handing the turbo over to a machine shop owner that's friends with my dad because he thinks he can fix it. If that goes south I'll be in need of a new turbo. My old one was basically a Garrett equivalent of a BB Turbonetics t3s60. The new one needs to be a T3 flange and i'm wanting to make about 250~275 hp at the crank and i'd prefer it to be journal bearing because i dont want to have to buy a new chra to rebuilt it(college student budget) the car is for time attack/autocross but i also want to be able to daily drive it so I'd want it to have a good spool.

So can any of yall recommend me a new turbo?

Nevermind, t25 flange. I'm really happy with my Godspeed turbo, so I would suggest checking their stuff out. Are you going internal or external wastegate?

only reason i'm weary of a chinacharger is i'm going to put around 15k miles a year on the car and a new turbonetics t3s60 would only cost about $300 more cheap insurance. i could reweld my manifold for t28 it wouldn't be that big of a deal and i'm going external

The chinese 3076R is actually a lot smaller than a real 3076R if you look up the measurements. I believe it was much closer to a 2871 if you are looking at the same one. But you should look up the specs yourself and not take the advice of some guy on the forumzzz. But I wouldn't hesitate to use it.
