  • Turbo Spec-V help

    I am helping a friend put a turbo in his 2003 Nissan Sentra Spec-V. We have the entire system in and plumbed/wired/etc., but we can't get it to start and idle properly. It keeps flooding one cylinder. We have swapped the upgraded injectors around, swapped coils and plugs around, and put the original injectors back in, but it keeps flooding the same cylinder. Tried dialing the fuel pressure regulator down but it seems to sit at the same pressure (about 60 psi) at idle. It started up but eventually bogged down (too rich I believe) and there was still gas in that same cylinder. Tomorrow we will pull the high flow fuel pump and put the original pump back in.

    I think we are down to possibly bad wiring to the injector or spark plug. We replaced the starter tonite because the original one broke due to hydrolock from the flooded cylinders. Pulled probably 6 oz. of gas out of the bad cylinder so I think the injector is leaking, but we primed the fuel pump a few times and watched it, didn't see anything come in after 10 min or so.

    Anyone have any ideas? Thanks.

    couldn't the only causes be bad plug, wiring, coil/(Pack?) or the injector duty from the ecu being wide open?

          Did a compression test today. The "bad" cylinder is not up to spec, and with the gas coming in I'm thinking the intake valve is leaking. We are going to do a leak down test this week, maybe that will shed more light.
