Well your first engine will make 220 HP stock, but I think that you already knew that. Anyways, as for the 2nd and 3rd, it depends. Before it blows or after

Seriously LS and B20?VTECs aren't a wise decision for daily drivers. You will have problems with it. Now if it's for pure drag strip racing, their fine. But not as daily drivers. Whatever you do, don't get the B18c head, it doesn't flow very well. The B16 head and the B18c5 (ITR) heads are both very much the same (nearly indentical) so why pay more money fot the ITR head? Most LS/VTECs I see put around 180 HP to the ground, with the B20/VTECs around 200 or so. Keep in mind that figure is before the engines throw a rod and need to be re-built. What is your ultimate goal here? 13's on the street? all-motor or FI?
