Original 605 gt 25. / some have gt20. Is very small device but for 1.6 is enough.
Have u considered a gtv? If so the 22 should make your dream come true.
How much fuel do u have?

what size exhaust housing have you got on your gt2860?
A/R or cm2
RE: gt2860 something smaller? - uli124125 - 05-14-2017
the small 0.64
i tried first the 0.86 with gt 2871 this was much too big for my way i use the car
this week im putting back the kkk k24
this setup was almost this what i want with a little defizite of horsepower at high revs
RE: gt2860 something smaller? - seanyt - 05-14-2017
i know the om605 guys with the gt2871 0.63 and remaps are getting good results.
But like already mentioned maybe look into a vnt or a he221 if you want more spool and low down.

vnt i dont want to have
with manual tranny the gt2860 is perhaps good
but with automatic it spools too late for about 400 revs
and by using with trailer the gt2860 makes less air and less pressure
whats about a newer form of the kkk k24?
how much variations does this turbo have?
RE: gt2860 something smaller? - uli124125 - 06-01-2017
what do you think about the gt2560?
for only 190-200 hp and 1.5 bar from 2200 on?
OM 602
i want to have spooling as early as possible

Gt2560r should do you very well. .64 AR. depending on the money you have to spend you you could go efr6758.
