Default Clunking = Collapsed intercooloer pipe?

Could it be? im 90% sure i have a collapsed intercooler pipe somewhere and my motor seems to be "clunking" Could this be the cause?

also will 100watt fog lights work in a 55 watt housing?]

edit would a vaccume leak cause you to have little boost?

Not sure about the first one

Yes, although you might burn something or melt wires.

Yes

clunking could most likely be timing off?

Clunking = not good.

you need to determine if its coming from the top of the bottom of the motor. Use a hose, PVC pipe or something that you can put on your ear and listen.

no, its from the motor, you hear it when im ideling in driveway. i dont think its anything serious, but id like to do a compression test on it.

Would a boost leak cause it to clunk?

A boost leak should not cause a clunk.

anyways it probably is an engine mount, how many are there, upper and lower?

and the performance problem is probably a wastegate adjustment (i hope)

how many of them are prone to knocking?

edit, does it happen often that wastegate loses adjustment?

The R/S one will clunk if bad.

The WG will usually never go out of adjustment. It is usually someone that moves it.

another quick off topic question, will a front door off of a sedan fit on my wagon?

edit: also my wastegate question... i dont have the time today to do it cause i work later, but i felt under the heat shield to the wastegate rod i though it was, and it seems completly loose, just by hand i could move it an inch in any direction.

Pull the heat shield and inspect it.
I think so I would measure to double check.
