DX motor runs mid 17's in a CX. I'm sure the EX/Si could do what you're estimating. The NA DOHC swaps I've seen around here run 13-14's.
u live in sea level? in AZ, N/A DOHC ( TALKING B16s, B18Bs,B18C-GSR,exluding the type R) are running mid and low 15s, to mid to high 14s. Most people around here have to build a little bit to pass low 14s and lower.
anyways, back on topic, i would say low 16s to high and mid 15s depending on driver and conditions
