I have a brand new stock replacement Garrett GT2554 turbo with the wastegate actuator and bracket included (and installed). It's totally brand new, so there are absolutely no issues with it whatsoever. I have checked and none of the vendors or other distributors (that I know of) sell them for less than $950.00 (+shipping), and that's without the wastegate actuator & bracket.
I can sell mine for $700.00 shipped and I'll include a stainless steel gasket that fits where the turbo mounts to the exhaust manifold. Let me know if you're interested, or I'll just start a for sale thread in a day or two. I also have an Apex 2.5" catted downpipe (one piece J-Midpipe) for sale which includes a O2 sensor for $200 + shipping.
