Rb20det Issues

[KURAUN]

Hey,

Latley I've had some problems with my Rb20, which all happened after I found out my ignition box ( the one that sits on top of the spark plug cover) shat itself . I took it to my mechanic and found out i needed a new fuel pump as well, he fixed everything and all was well. But recently when i start my car, after priming the fuel pump the light on my dash that looks like a cat converter with steam will stay on, but only until I get on the highway, where it dissappears when im accelerating but when i change gears and the revs drop slightly the light will appear again. But once I have got to 100km/h the light goes away. But its not everyday that it does it and sometimes it will appear dim under light acceleration, but just enough so you can see it. Lastly my turbo is whistling a lot louder, and once when i pushed it before the light started to come on was makin a screaming noise oin high boost (which is still at stock 7psi). Lastly to add when the light is on the car feels as if it has boost all of a sudden it kicks in and out of bosst in low revs before it shouild be boosting like 1/5 - 2000rpm and it feels sluggish you put you foot down and the car dosent move, but this is only in the first few minutes then the cars drives normal again. :

Any help will be much appreciated

Thanks Nick

check cat isnt blocked

Well light is fixed it was a blocked cat. But turbo still whistles really loud and screams on boost, maybe has shaft play?

Inspect and/or replace your dump pipe gasket and manifold to turbo gasket. These can be sourced direct from nissan.

goodluck

i had similar problem with mine ...... turned out to be the manifold/ turbo gasket, now no more screaming!
