I've got an unported evo mani, unported 14b, and unported evo o2 with no exhaust open dumping, stock 7.8:1 compression 2.0. I decided to test it, I put it in fourth gear at 1000 rpm and rolled onto the throttle. By 1400 rpm I was at 0 psi, 1500 started showing positive boost and 5 psi soon after that, and 12 psi around 2250. Spools too fast, almost. I've got a die grinder and carbide burs on the way so I'll see what kind of spool improvement I get from a full port job.

I wonder what a 14b would be like on a 9:1 2.4?
