he wants a receipt for my exhaust, muffler, catalytic convertor ( not equipped) all were installed my a local muffler shop that doesn't give receipts. also wants pictures or my recirculation valve, intercooler piping and engine bay. as well as reciepts for my oil feed and drain. then he will submit it to a turbo builder for warranty....so contrary to popular belief he doesn't build, rebuild or balance turbos he sends them off.and even though he sold a garbage turbo i have to pay all the shipping back to arizona. this guy is not standing behind his product at all.
The receipts for the exhaust work sounds out of the ordinary to me, but asking for receipts for the oil feed & drain tubes is pretty standard fare for anyone trying to have a turbo warrantied. Pictures of your installation, CBV, etc seems about normal to verify proper installation, goes hand in hand with the proof of new oil supply lines. I.E. You can't get a fuel pump warrantied without showing proof that you replaced the fuel filter at the same time. This practice is common.
Paying for return shipping is also normal, until root cause of failure is determined. I wouldn't be surprised if your return shipping (or a portion thereof) was refunded to you if it turns out that the turbo failure wasn't your fault, but they need to inspect it first. Much of this sounds like standard operating procedure for a warranty claim. It's not as cut-n-dry as we'd like it to be. Manufacturers and rebuilders have to protect themselves as much as anything else. It's all business.
iPd doesn't build turbos either, or most of what they sell for that matter, but everyone is quick to say that their turbo is a iPd 19T, or iPd strut brace, etc because that's where they bought it from. All iPd is, is just a company providing parts & service. Not unlike Tryingbe with the turbos. He's providing a turbo rebuild service. Sounds to me like he's trying to stand behind his product and help you get this situation resolved. But his hands are tied as much as yours, you'll both need to adhere to the rules set about by the company that rebuilt the turbo. You'll have to help him, help you.
(...and think of it this way; for every 1 turbo that is installed and setup correctly, there are a dozen more that aren't. Shops would be out of business overnight if every person with a "new" smoked turbo got a warranty job without first investigating why it failed.)
