None that I know of. I think it's a cheap chinese turbo. I got it because its specs matched or were very close what I was advised to look for.
Also fellow forum user Stevensimon took the plunge before I did so I didn't feel like I was stepping out onto the ice alone.
I'm still a noob to turbo stuff with only one under my belt so far. It was an S5 turbo install on an old school 4 port R5 13B in PercentSevenC's FB as a blow through on a Weber DCOE with a locked dizzy and no intercooler so far. It boosts up quickly to 5psi then lazily increases (perhaps creeps) to 7.5ish which seems to work very well. He's going to get an FMIC and a boost controller at some point.

I've got a pre A series engine so 500 is my max safe limit. But yeah it's streetported and the turbo is probably good enough. It's one of those fairly cheap cxracing turbos with a .96 hotside small enough for good spool and driveability but large enough to max out around 500 hp.
Walbro 255 and bosch 1600 secondaries. Still debating whether to size up my fuel send line (from stock 5/16 up to 3/8) and get a second walbro to run them parallel.

Chinese turbos have been known to come apart under load, and it'd be a damn shame to send pieces of compressor wheel into the internals of your 20B.......

I'm not a noob to turbo stuff, and you couldn't pay me to install a chinese turbo on any RX-7, let alone running one on a 20B. My advice is to deep-six that thing, and keep on the hunt for a nice used Garrett or Borg Warner turbo.

Here is the one Steve and I got, but the water cooled version. Is it any good? http://www.cxracing.com/mm5/merchant...gory_Code=TOCH
Maybe it's not a cheap chinese turbo.

i would not spend money on that turbo, buy a name brand hell even buy used before using a Chinese made turbo. also look at the suggested horsepower rating. its rated 500-700HP thats from a piston motor it will not give you that much from a Rotary.

You are correct, sir. I chose that turbo so its 500-700 piston HP would translate to 350-475 rotary HP, which is right in the range of daily driving. I only suggested 500 as a peak or max HP because my engine is a pre-letter series.
