OK about two months ago i bought a JDM 10:1 motor. Before I got it I ordered my JWT ECU. I went ahead a put the motor in my NX, but it ran VERY rich. The guys at JWT said that it would be alittle rich due to the different c/r of the motor, and told me to wait till I got the ECU and try again. Well I got my ECU testerday(after 8 weeks) and it still runs rich. I am thinking that maybe I got some of the vaccum hoses wrong. Could maybe someone with a JDM motor let me know which ones go where. I am talking about the ones for the throttle body. I need to know about the two that face the firewall on the side and the one that comes off the bottom and points toward the driver side. I know that one goes to the FPR and one goes to the intake. Any help would be greatly appreciated.

OK since nobody can help me with that have any of you ever replace your stock Fuel pressure regulator? If so where did you get it, my local dealer wants 70 bucks for one. I am going to buy it unless someone has a better idea. I want to get my car fixed by saturday so that I can take it to the track.

i don't know where to get a new one other than call greg at mossyperformance.com and see what he can do for you.

Well I talked the guy at ADvance auto parts to give me one for 65, and it will be here tommorow. Have you or anyone else ever taken off the fpr or the injectors? If so how did you get those damn soft ass screws out? I have had a big problem trying to remove them without stripping the head. And I am still not sure about the vaccum hoses. JWT said that 99% of the time that it would be the fpr. I am worried as hell and don't know what to do. I haven't been able to drive my car for 8 weeks now.
