    140kw on 13psi gt28r stock t28 with ems 4424 bigport cams 3" zorst. Soon to get tuned for 16psi so ill update it later. Recommend going for brand new turbo as ive been thru 3 t28's and all had problems. Ive got a gt28r hiflow to gt28rs spec "disco potato" from Hypergear. I highly recommend them for the atr28 or even there Hi flow service.

    I'm actually wanting to get a brand new Garrett gr2860rs or 2871r. I'm not sure yet tho. I don't want it to be too laggy tho. When do u start making some boost?

    it spools really early @ 2000 then full boost @ 4000rpm if i run high boost i get 19psi boost cut by 4200. This is with a stock gt28r. I am yet to fit my custom gt28r internally gt28rs chra core turbo but it will spool earlier. Its flowed to push 20psi reliable and rated to 350hp. Looking forward to it

    i wouldnt be asking power figures for a turbo selection ( unless your just chasing power figures) id be asking diff ratios, and how laggy and how much top end!!

    also depends what ur using it for, so heres a few i had

    kkr 280 made 169kw on 16psi, came on fkn hard had good top end 4.1 diff. used for drift

    t28bb s15 made unreliable power figure lagier awesome top end and would make boost to 20psi easily 4.1 diff used for drift

    t28 non bb made 129kw on 13psi came on hard as fk good midrange and top end all round good turbo but bush bearing so had its limits, used for street 4.1 diff.

    not on a 4agte but put a 2871 on my sr and its a fair bit lagier than a t28bb and would be heeps farkn lagier than ur kkr280 and that was with 4.5 diff!

    130rwKw on TD05-14b running 11 PSI. Stock AE101 GZE bottom end with 20V Silvertop Head and Motec M4. 4.3 Diff gears, full boost 3700ish, but turbo wants more boost for sure.

    Soon to be 7AGTE, will be 20psi+ and will see what the figure is.

    Friend had 2871R with .64 rear on his SR20 and it felt laggy, dunno what would be like on a 4A....
