Ok heres whats going on, I hope s/o can help.
So my first post (so nissan wont warrenty my Z) for the full story.

Well nissan finally put the engine together and in the car.
Problem is from what I understand, it starts but will not stay running. They told me it started, smoked a lot and died.
It has no form of forced induction right now and has stock computer.

The checked the timing a few times and said it's dead on. It has fuel, spark, and air. The engine is 8.8:1 compression. Nissan did a compression test and it came back with 130psi on 4 cyl, 135psi, and 145psi in the other.
I was told from a few tunner/350z specialist that it should start and idel fine, it just wont have much power.

The mechanic says that it will not run with no turbo on it, at idle the turbo really is not doing anything then is it?

Any one know of a Z with such low compression that has been driven or even started the engine with no forced induction on it?

Any idea on what could be wrong or something it needs to be drivable?

Thanks for any info

 

10% is the accepted tolerance for variation between cylinder pressures. With that said, if you have proper timing, ecm control, fuel and spark there is no reason it won't run with 8.8:1 compression, with or without a turbo. Something else is wrong.

 

Won't run with out turbo? How would it run with the turbo installed and no boost at cruise? also smokes alot? what is it smoking oil ( blueish white ) fuel (rich ). Didnt ask about coolant because of good compression check (head gasket).

 

i purchased a utec today. I hope this will fix the problem. from what i understand i need to find s/o that can tune it. I was told I would have to create a map from scratch and kinda guess at everything and get it as close as I can. I was told if I dont use a utec or something that it could mess the motor up. Hope I can find some help there.

The smoke I'm not sure of b/c I as not there when they tried to start the car..
I'm still going trough the problem with nissan. I was told by a few it should run off the stock computer and by others that it wont.
