Besides the B series, i would go witth the infamous K swap. K20A2 from the RSX-S or Civic Si, it produces about 200hp, 6 speeds and redlines at 8k. Another swap is the H22A swap from the Prelude. Im not so sure about the HP, but i know that its fast. Im thinking around 200hp also. Plus, you can use your B series transmission, known as an H2B swap. Or if you dont want to do a swap, you can always do an LS /VTEC if your car is an RS, LS, SE or GS. Those have a B18B1 non-VTEC, so you could use a VTEC head maybe from the B18C1 (GS-R) or the B18C5 (Type-R) to make it LS/VTEC.
