Does anyone on here know of any machine shops or engine builders that know and understand the GN engine? Im looking for one in the Las Vegas area or within a few hundred miles of Vegas? I need mine rebuilt with a mild build. Any help is appreciated.

Do you know if someone makes a complete kit or do I have to buy all the parts seperate?

I am trying to find out if the turbo oil seal for the stock turbo is available seperately from the turbo? Or do you have to replace the complete turbo? If the seal is available seperate, then who sells it? Mine smokes when cold started and I believe its the turbo seal as I have read on here...

I assume you mean the rubber part of the return line at the fuel pump. Which of the three rubber lines would that be? So I can check them.

With fuel line off the fuel pressure is 55PSI. I get it up to about 58PSI & no lower then the 55PSI. I dont remember the brand, but it does the same thing with the old or new fuel pressure regulator.

Does anyone have any ideas wht my fuel pressure drops to zero as soon as the key is turned off. Also I cannot adjust the fuel pressure more than about 3-4 psi. The fuel pump and fuel pressure regulator are brand new. Car does the same thing with these new parts as it did with the old fuel...

I may have a leak at one of the injectors. There is no gas leaking, so I think that it is internally in one of the injectors. Only thing is how do you test them or find out which one it is?

Replace FPR and there was no change. I was wonder if I had a bad injector. The injector harness is new when I did the injectors. How do you test for a bad injector?

So last night I put another Walbro fuel pump in the GN. Car still runs horrible. I have 50 psi of fuel pressure at idle. A brank new adjustable fuel pressure regulator & I can only adjust the fuel pressure about 4psi. The fuel pressure drops to zero as soon as you turn the key is off. Key on...

PM returned Thanks Again

Mine took a dump with less then 200 miles on it. Just installed it less then six months age. Gas tank is half full & dreading pulling it out with all that gas in there. Going to try another Walbro though, I will give them ano more chance.

Are they having problems with the Walbro pumps. I only have about 200 miles on it since installing. I will also check the lines. The only rubber lines I remember is the ones going to the pump, so I will have to drop the tank again. When I did install the pump I could adjust my fuel...

So I have replaced the Idle air control and the fuel pressure regulator. When I hook up the fuel pressure guage, I can still only adjust the fuel pressure about 5 psi, its up around 58psi at idle. It will not adjust any lower. When I turn the key off the fuel pressure drops to zero right...

No mine is not a fixed one and has only been used once. Hopefully it is still good.

What do you suggest. Rebuild fuel pressure regulator or replace ir. I do not know what brand I have.

Ok so I just installed the LS1 MAF sensor and MAF translater and the car does run better when driving. The biggest problem I have is when the engine is cold the car idles bad. When driving and acclerate from a stop either hot or cold there is stumble like it cuts out for a second, unless I...

I work at a Nissan dealer. The battery policy is if the car is under one year old Nissan will pay for a new battery. If the car is over one year and less then two years old Nissan will pay all the labor and for half of the battery. So you would have to pay for the other half. Should be about...

Thats what I was thinking. The less adjustments the better. :biggrin:

How much?
