I WANT NO BASHING OF EBAY TURBOS IF YOU ARE GOING TO BASH SHOW ME THE PROOF I WANT MORE PROOF THAN" YOUR GRANDPAS SONS GIRLFRIENDS CHILDS KID HAD ONE AND IT CRACKED "

also i am knew to turbos i mean i know alot about them but i dont know all the differnt types and i dont know like how much hp gain i will get will it be night and day ? K04-015 new on a 236,000 mile engine that has no sludge ? how much hp should i exspect btw my k03 was throwing overboost codes i think i have a bad n75... will replace later

 

Unless you're overboosting because of a failure, you won't see anything beyond the difference between an old turbo and a new one. If you really want to see what a k04 can do (which isn't tremendously impressive), look at the turbo guide in the TT subforum, stickied at the top, as well as the 1.8T modding guide at the top of this page - all the info you could want.

 

As for the knockoff brand experiment, keep an eye on end play/wobble and shaft seal oil leakage over time at regular intervals. The bitch with the Chinese turbos isn't that they break when you take the plastic off them, it's that they wear out very early.

 

the issue with chineese turbos are the turbine housings, turbines, and especially bearings.

ha ha, yeah right. and even if it was ball bearing, id trust a chineese journal bearing over chinese ball bearing any day of the week.




seriously wtf are you talking about? its true, the compressor housing is typically made of aluminum, which is a non-ferrous metal. the turbine housing and center housing should be iron, which is ferrous and very magnetic. if the turbo isnt magnetic i'd be concernded, unless of course you tried testing if the aluminum compressor housing was magnetic?

either way, people dont get it. all chinese made **** comes from the same factory. theres no difference. and there is plenty of well documented evidence that chinese k04's are junk at anything over stock boost levels.

 

Reading that OP makes my head hurt. Please cut out the all caps ****, and use some punctuation. Jesus H. Christ.

Wut? What isn't magnetic? If your magnets didn't stick to ANY part of the turbo, I'd be worried.

Lots of people claim lots of things, that doesn't make any of it true. Show me photo evidence that the turbo in your hand uses ball bearings and I'll believe you.

What does "numbers on the spools" mean? Part numbers? Why would the presence of part numbers indicate to you that anything was balanced or tested? That makes no sense. Are there any grinding or machining marks where material was removed? Oil residue is a good sign, but how do you know it was from testing equipment? Was the turbo installed before you bought it?

Yeah you're right, all of the threads and documented evidence of these turbos being polished dog **** were part of a big conspiracy, you're right and the rest of the internet is wrong.

You're "knew" to turbos, but you know a lot about them, but you don't know that slapping a new turbo on your car with no tune and no supporting mods won't do a damn thing for you? Man, I didn't see that coming with all of these fool proof, highly scientific tests you ran on your new turbo.

You will see exactly zero additional horsepowerz with your new Chinese turbo with no tune and no supporting modifications. If you think your N75 is bad, run a piece of vac line straight from the compressor housing to the waste gate and see if the over-boost condition goes away. You should see about 5psi from the waste gate alone. Do you even have a boost gauge? Vag Com?
