Forget about the shoddy balancing or basic bearings, if they have a TD03L turbine wheel (as they likely do) with a 16T compressor they will make about 475-500rwhp on a well tuned ethanol car for about 250-1,000 miles, at which point they'll start leaking oil like a sieve and by about 2-3k miles you'll be at the point of tossing them in the garbage when no one responds to your email about a warranty replacement on your junk $800 turbo purchase. Sorry for the negativity just felt compelled to be a crystal ball on this one, by all means give it a whirl and report back.

If that be the reality of it credit cards will protect you from fraud if they claim a set warranty and say they go out in a few weeks. All you simply do is simply call the credit card company and explain exactly what happened they may want you to send them back but you WILL get your money back. I think the protection is up to 6 months with any Credit Card. I wouldn't buy these without a at least a 6 month guarantee. But how are the other cheaper reputable turbo companies doing? I heard the Vargas GC are garbage by alot of people. What about RB Hexxon MMP etc?
