How much experience do you have with no name chinese turbos? Yeah. Stupid question.
I guess it's a stupid question to you if you don't have experience with no name parts. There is some weird mental thing with the import and euro crowd where a lot of guys are just total brand name loyalists. Most have no experience with any of it whatsoever, but they know a brand name, so that's all they want. These same people are the ones most likely to forego proper tuning of the combo. Hard parts don't mean jack if it isn't tuned properly.
The reason
most off brand or no name parts have a bad rep is because the people that usually buy them are those that can't afford anything anyways, so they half ass it all, and shit doesn't work right. They are also the ones most likely to DIY things when they have no comprehension of it, and things don't work right.
Am I saying that a chinese GT45 is going to spool as fast as a Xona or Garret Gen2? No. But will it break into a million pieces in 5,000 miles? No. Plus, it will still flow what a $1,200 Garret does, and it costs $250. Guys do it all the time. Hell some of the off brands have become a brand in themselves - VS, MasterPower, On3, etc. Their price typically goes up as their reputation increases as well.
