hi, i have just got my jdm b18c sir-g motor swap in, and i am almost done with the swap, i have a couple questions, is there any way to tell if the head is jdm or usdm, i think it might be a usdm head on a jdm b18c block, if this is possible, and if the head it usdm, will it make a difference, in power or regular running? also should the factory header on the sir-g motor bolt up to my factory exhaust, i have a 94 civic si, well if it supposed to, its not on my car, so i dont know whats wrong. also where is a good place to mount the o2 sensor on the header, until i get my itr header? thanks alot.

check to see if there is another sensor coming out of the v-tec selonoid. if there is then its usdm if there is not then its jdm. this is not 100 percent but damn close....

well, if anyone else can help, i will aprreciate it, but thanks for that, also i started it for the first time today, it ran fine for a minute or two, but then it died, and would only start for like 1 second, then die again, i have a vafc, and it is showing no thorttle position, so i think somehting might be wrong with my tps(throttle position sensor), if not i dont know what it is, it seems like its not getting fuel, does anyone no what can be wrong, there is 3 exceptions though, i dont have the o2 sensor hooked up, or the secondarys, or teh knock sensor. does anyone have any ideas? also, how do you hook up secondarys, i have the wirring diagram, but where do you go into the the motor, is there 2 sensors or soemthing, i ahve never done this wiring befroe, can seomeone give me detailed direction so wire them up. i know this is aksing alot, but i need help, thanks
