The thing is the Chinese GT Garrett copies that Toyo Sport down the road from me sell for £189 have a much better finish to them i've never seen a worse finish on a turbine housing ever let alone on a turbo that costs over 8 times as much!

For all the it's not how it looks but how it performs guys I'll liken it to my day job;
I work for Severn Trent Water so when a customer askes for new MDPE service to be laided up there drive way we go out dig a trench remove the old lead or copper or whatever their curent service is made of laid a new length of 25mm MDPE and reinstate the footway and drive way clean everything up and Bobs your Nan.

Let's say we just dig it out leave all muck up against the wall/hedge whatever connect up the new MDPE and put some road plates over the excavation.
Then the customer complains (and rightly so) and we say; "Have you got water?" "Can you still use your driveway?"
"Whats the problem you have better flow and pressure now, it's the performance that matters not what it looks like!"
