well as far as i know the series 2 rb25 and rb25 neo r the same turbo i hve 1 on my rb20 and it goes really well but its was on there before i got it so i cant tell u how much diff it made
i hve heard a few diff things and wanna know i hve an rb20 with a stuffed bottom end if i got an rb30et bottom end could i swap everything over and is this a job for a professional
i bought some cams off a guy from a 33 gtr he told me he had some in his and they worked well but i put them in and it ran like a heap just wonderin if ne 1 had tryed this btw i hve an rb20
