this bolts onto stock rb25 manifold it has a t3 flange which is the same as the standerd one
this turbo is right for 22 psi,
i have a to4 on my r33, n im pretty happi with it, still yet to dyno though
kicks in at 3.8
so if u dont mind the lag, n like the price, buy it
"speed freak" u can get ur performance work shop to look at it, i got no dramas with that, but it have to be a sat cuz i work mon-fri at south side toyota.. cheers
