Vaccuum leak or something else?
So I installed my turbo inlet today, and now when I turn the motor off, and when I start it up it shakes kinda violently and makes a weird rumble sound. I'm thinking I have some air leak somewhere, the clamps on the OEM part didnt fit on the new inlet so I dont have any on there. I reset the ECU when I was done, no CEL yet, car runs good, pulls hard and makes boost fine. Would a pre turbo, post MAF leak cause the engine to do this? Im sure I got all the hoses on the inlet, they cant really fit the wrong way and I labeled them before I started. Do I need to get some bigger clamps or what?

a vacuum leak will make you idle rough, did you get all those hoses connected well to the turbo inlet? pcv and the like?

I did a long write up with part numbers and places where I bought them to fix the "T", I know exactly what you are talking about. The Perrin TI I got either had and extra nipple, or was minus a nipple ( too long ago), but I solved it. Scooby mods dot com, with pics under the Perrin TI install.

I got clamps on the inlet hose and got an elbow for the PCV valve and the idle feels a lot better. It still shakes at idle sometimes, and when I start the motor up and shut it off it still makes a knocking sound and shakes, but not as bad as before. Do I still have a leak somewhere? How long do I give the ECU time to learn? Once I get moving the car is fine, boost seems to come on a little sooner and the turbo is definantly louder. How do I check for a leak in the hose? Does the propane torch trick work for something like this? Any advice is appriciated.

Dru,
Sorry I posted it at club wrx. Here is the link from this site. Inside it you will find the link to club wrx and my pics and how to. http://forums.nasioc.com/forums/showthread.php?t=964293 http://www.clubwrx.net/forums/showth...rin+inlet+hose Posted both threads up here for you. On the club WRX thread go to the last page, you will find my write up. Hopefully this all helps you, I have had no problems with my car. You may still have a leak, check around the inlet pipe real good, ensure it is seated all the way around the turbo. Let me know how everything works out. Quote:
