B18c7 or b20 block?

Ohk.. With the b20 block it will bolt onto pr3 head perfectly right? Also the gearbox as well??

Yep. But you also need a VTEC conversion kit to supply the head with oil. A lot of information about B20VTEC swaps on this forum!

Pretty much all B series hydro gearbox will fit up to any B series block!

NO

You need to re-drill the B20 block to take the VTEC head bolts, they do line up though.

You will also need to use the VTEC water and oil pumps, just FIY.

There's a B20VTEC thread on here with lots of info, just do a search for it.
