Its a tough call I know I still considering it I have the injectors waiting and a z32 afm as well. But I'm un sure I really want more than 200 rwkw from an rb20. I really liked mny vg30 turbo ands I have a sneaky thought that you will like the 2510. but one thing to consider are you going to do the rb 25/30 or is it a hope rather than a dream If you are going the rb25/30 later buy the turbo once and get a t3/4 if not the 2510 will be good. as I said Its a tough decision I'm looking like going for an rb25 turbo with steel wheels If I can or just with ceramic wheel dial in 13.5 psi with the actuator and be done with it. and may be in a year or so get a a wild set up but don't hold your breath for that.
