Does anyone know how big honda fuel pumps are? I have a 96 cx hb with 98 JDM B18C GSR with AEM cold air intake, DC 4-2-1 header, JG intake manifold, Fsudo complet catback with high flow OBX CAT, with 98 JDM type R ecu, AEM fuel rail, AEM fuel pressure regulator, H22 injectors, NGK spark plug wires and $6 each spark plug(forgot brand), and a pair of skunk2 stage2 camshafts(both intake and exhaust) laying around uninstall because I need the valve train(waiting for my financial this week). HERE ARE MY Three QUESTIONS: 1) with the above mods, what fuel pump do I need to use and how big??? 2) I can install the camshafts myself, but I havent done the valve train. So, when I get my financial aid and buy the valve train, as far as installing the cams and valve, are they any modification need to be made??? are the skunk2 cams and valve bigger? wider? than the GSR? or are they just drop in as replacement? 3)Also, since I did not know how to install the valve train and taking to a shop would cost me quite a big. Therefore, if I decide to install only the cams, and shift at 8200k would this be any problem since I did not install the valve train??? Since where I live have no smog check, the result of having rough idle due to install these cams will not affect my decision of install these cams.Thanks in advance for your helps.
