i ran one on my rb20 for nearly 12months .....on 1bar.... spooling by about i dunno 2800 , 10psi by 3700-800 & 1bar say 4500 holding it to 7500 .... not 100% on the rpms coz i dont really drive staring at my boost guage. i also ran a turbotech bleeder which helped quiet well for spoolage. .. without it .. it was pretty bad.
powerwise .. at a guess iwas creeping up to 160rwkw with th auto
0-100 in 6seconds. very similar to a 25 turbo on my m8s silvertop .. just fractionally later that my opinion though
my turbo has a ceramic rear wheel on it.
only reason i put it on .. was the turbo was very cheap .. and as its first turbo car i wanted to see what everyone REALLY meant by rb20 lag monster. very lack luster for response if u want "go" liek a stocker turbo
if u drive in traffic alot ..its pretty useless.....alright if ur going in a straight line for a while..... shit for track or twisty use unless ur in the revs the whole time.
