I have a .63 t3/t4 on my sohc and i see 7psi by 5k easy. i'm sure yours won't take until 7k to spool, but once you shift your good to go again, flat foot shift it and you won't have to spool up again. Flat foot shifting is what i have to do to keep mine alive on the track. If it's a b18c and not the b18c1, Your comp ratio is 11.1:1 which is going to help out a bit. as for high revving, when my friends car got tuned (b18c, t3 60-1 .63) he made 360hp on 14psi, but the car didn't make any power past 7800rpms. so they set the revv limiter to 8200.

Either way you go, you're going to have fun with it.
