SR20det: Boost leak? Wastegate? Or?

[st280]

So every now and then I'll get this problem where it seems like I'm getting a boost leak I think. And it was a problem for about a week last week, and I tried spraying all of the hoses with soapy water to look for bubbles and nothing... Well couldn't find anything, and I finally went out and just got it sideways, and as soon as I came back to my driveway, the "boost leak" disappeared?



Well, I got sideways again, and now it's back? I can't keep a constant speed without it seeming like the boost is dropping off. At WOT it pulls pretty fine (not full potential it seems).



This is me at idle, trying to keep a constant RPM at about 1900...

Any idea as to what this is? I have my bumper off right now, I took off and retightened all of my couplers. And have pretty much new vacuum hoses. Any suggestions?

ok well first things first. this should be in the sr rwd forum not here.

things I would do: sounds like u have some gnarly exhaust leaks. I would check/ re tighten EVERY nut and bolt on your exhaust starting at the manifold, then the turbo flanges, elbow, and so on...

after that repost the rezults.

wastgate could be stuck open...

Id lift the rear end of the car up on jacks, then try and boost the car in gear, have a friend watch to see if the gate opens or not. there is probably an easier way to do this but wateva.
