i know a K26 is used on some alfa/lancia 2.5td with 110-125hp i thought.
if you were from europe, i could give you a opinion, but the shipping never will be worth it.
i know we are in for sale/ needed section, but i dont see the usefullnes of a K26. i bought my GT2252v for 123€! (its from a vwT4/T5 2.5tdi) i think you can have a good vnt turbo for max250-300€. if you search good like i did, you find the good stuff for less money :wink: Audi80 got around 170-180hp with a gt2052v (from any vag2.5tdi, exept the t4/t5 bus) those engines are stock 180hp, and can get +200hp with this stock gt2052x turbo, i dont know or a will td use more air than a tdi common rail for the same hp?
Just my 2cent, good luck!!!
