This is why you do not want to use the GReddy hoses...

The hoses that ship with the GReddy turbo kit are of extremely poor quality. They might not break for a few months, but sooner or later they will.

Here's what mine looked like after about half a month.




Upgraded hoses:




Someone remind me to post a list of all the hoses and sizes needed...

The hoses are poorly made, and cheap. They don't hold up to the pressure (even 6 psi) for long. When it bursts, your car will be sucking in unfiltered air at the burst point. When you're in boost, the car will lose pressure there, and be unable to hold boost for more than a few seconds...

Here's a parts list from the Greddy install manual:
