Ok i've beenrunning 8 psi on a 14b for about 2 weeks now and it just wont' boost. I started up the car today and it ran fine but the boost guage will shoot from 20vac to 0 psi and won't boost. I checked for any leaks and put the car in neutral and reved it up and I put my hand where the IC pipeing connects to the throttle body and I could feel air getting pushed in. What's the deal?

also I noticed a little Oil right where the IC pipeing connects to the turbo.

 

you cant create boost in neutral you need to pressure test your intake system. It probably just blown coupler or something

 

sorry this is my first tubo install, how do I do that and what is a coupler?

Check all your charge pipes, Make sure there all connect and tight.. Also, If you arent using T bolt clamps i would suggest them.. Couplers are the silicone things on each end of your intercooler and the silicone things that connect your charge pipe down around the intercooler. But just check all your piping and make sure there connected secure

 

piping is disconnected/leaking somewhere. Hole in the intercooler. turbine isnt spinning freely. take your pick. Might check your exhaust side of things too like a WG stuck open or a cracked manifold but those should be pretty obvious.

 

I thought I had this problem as well, but it just turned out to be a problem with the MBC. It was really weird and I can't quite explain it.
