Need opinions on turbo upgrade.

Well i wanna move from archaic journal bearing to more modern duel ball bearing turbo. I cant go to big cause i dont plan on ever running more than 10 psi maybe 12.

Here is my options as i see it.

Get a brand new DuelBallBearing center section for my T3/t4e 57trim and basically just make my t3/t4 a duelballbeaing system. about 950 bucks.

Or get a Garrett GT3071R Or sumthing similar sized and just upgrade the whole turbo. Ballbearing compressor and what not to sumthing more modern.
1375$

Will the price diffrence be worth it and how well does the DBB turbos run compared to journal bearing...or is ist just hype?

Any info on the GT serious and such is welcome ...thanx.

gt2871r will be too small IMO for a 2.5L
this is what I am getting for my 1.8L in my GTI. Very decent size for under 2.0L if you ask me

GT3071 will be better. I would definalty change the whole turbo for 400$ difference.

I heard BB turbos gives around 500rpm sooner spool up time compare to journal bearings.

edit*
Mnemonic, it even says on the atp site that is good to up to 2.2L
Do not get this turbo for a klze !

I thought that too at one time. But after further research I think the GT3071R would be a much better fit. Up to 400 ponies and more suited to a 2.5L.
