Would oil backing up through the drain maybe have an effect on this? My drain has a slight kink in it, I'm addressing that. I ran the car for about 5 minutes the first time. Towards the end before I shut it off because of the turbo not spinning, I started to burn a little oil. When I started the car for the second time I had no more smoke. Maybe the waste gate was leaking.

Thats possible I guess if the drain isnt working properly.

Are you running a -3 feed from the relocation block with no restrictor and your drain is at least a -8 going to either the girdle or the front drivers side of the pan?

 

-3 from the pressure switch not of the sandwich plate. -10 return to girdle. Only thing is the line is kinked and I was seeing a lot of oil pressure. I don't if it's the gauge but I had 40psi at idle.

 

I don't think there's any way the turbo should not be spinning. I can blow into the turbine housing of a GT30 and make it spin easily. JB or not, it should be spinning.

I'd check the wastegate as it might be open. Or you have a major exhaust leak. Or the turbo is a piece of crap.

My buddy ran into this issue when we put an internally wastegated turbo on his civic, but ran an external gate. Well, he forgot to close the internal gate so all the exhaust gas was bypassing the turbine wheel. It stayed still at idle but spun up a bit if you blipped it. Well, as soon as he held the internal gate shut, the turbo spun up immediately at idle.

 

its ok if it stops when idling low if you have a large hotside with a JB. seen this before on some b-series turbo cars. especially b20b/z's. they have lower comp than most of the gsr's etc, and a .63 hotside of T4 60-1 would sometimes just come to a slow stop and barely move at idle.

whats your turbine A/R? and, if it stops and you spin it with your finger, will it take a while to come back to the stop while idling? if so, its just a big housing JB and you probably have a thicker HG too.

if what i asked is true, than its normal in some cases.

 

all turbos are different. every larger turbo I have ever ran did not spin at idle. Ball bearing turbos will but journal bearings dont always. I wouldnt stress about it if I were you. Put a few miles on it and then see how it is.

 

here is a video from my new turbo on startup for the first time. as you can see the wheel is barely turning even on a higher idle. PS dont mind the messy engine bay, still needs a lot of work.

+1 on checking the wastegate. if thats not stuck open then your probably fine. if its spinning perfectly freely when you try spinning it by hand then it should be in ok condition.

 

Did someone say it's "shooting out rocks"... NOT GOOD.
