If I understand you correctly you are using an OBD1 or earlier computer on an OBD2 block. Are you sure all your wiring is OK? It sounds electrical to me, if your head was leaking you would notice coolant or oil coming out. the fuel pump doesn't mix fuel, it just delivers it, I suppose it could be the problem as it is used to supplying a car with only about 100 wheel-hp now you are asking alot from it.
Don't bang on the Lude, it may be heavy but I've driven an SH, it's faster than people give it credit for. It's definitely faster than an Si which is supposed to be 15.2 or 15.1 not sure which. It was a LOT of fun, I'd trade my Civic up for one instantly.
hey guys, i guess the hybrid veterans haven't really seen this thread so i'll add my $.02
you have kind of a strange combination. essentially you're running a GSR motor on a B16A ECU. this is no good. you'll need be using a custom ECU with a better fuel map. also, if you assembled this motor yourself, did you give it time for the piston rings to seat before your revved like mad? do a quick compression check and let us know. the JDM B16A SiR2 head is far better than the B18C1 head. the B18C5's head is just a p&p B16A head.
best thing to do right now is get it on the dyno. see what kind of numbers your making. also if you know anyone with a custom ECU, bring that along as well and dyno with that. see if the source of the problem is the ECU's fuel map.
good luck
