well i finally got around to putting on my 14cm wg housing. i built a home made adjustable waste gate set up on it and while i was pulling it apart i notice the 12cm housing was cracked in 5 or more places. is this a common thing? i have got it plenty warm, plenty of times, but this even suprised me.

 

i think this is a better pix

 

This is not a common problem, unless you over-boosted, and ran extreme heat. Your lucky the turbo didn't go, and I supect the turbo shaft and bearing is on borrowed time.<br><br>Steve

 

it has hit 45#s of boost and pegged my egt gage more than a few times.
