Taking longevity out of the question. How would a knockoff gt3582r such as the cxracing or Godspeed turbos compare horse power wise, to a real garrett or even a BB or jB precision 6262? Has anyone ever dynod a knockoff gt35r? Or even better switched over to a real Garrett turbo afterwards to compare?

 

Wheels aren't the same size..

 

Not even close. Your not even getting an exact copy of the gt35. It's smaller exhaust whee. And much smaller compressor wheel. Sometimes the comp wheels are a little smaller but all in all don't expect 62mm numbers out of one of those pieces of crap

 

Hell, don't expect regular GT35 numbers out of it.

I'm officially waiting on the Godspeed/eBay GT35 12psi user to chime in as part of a feeble attempt to dispel and counter the reality of this silly little widget.
I'd even run a Precision before one of those things...

 

Don't expect anything out of it really. If not for the fact the turbo isn't even close to it's advertised size then remember the odds of the turbo failing are higher than purchasing price
