i bought a 18t turbo,and on the turbine wheel it says 15g,i called the guy and he said he built the turbo hisself and that he change the inside (intenals)which made it a 18t.my question is does the 15g ang 18t have the same size turbine wheel or is this the wrong turbo?is thete any way to checkh to make sure it is a 18t by checking things on the turbo.i have the turbo 18t in my beeroom so i can look for anything that you guys tell me to make sure it is what he said it is,and what i paid for...thanks for anyinfo guys...i really appreciate it guys,and hope you can help me figure this out.he said i could send it back it i felt that i dont have what i ordered...thanks again.

But to answer your question, the turbine wheels are the same.

so the turbine is the same size as a 18t,even though it say 15g on the turbo.so when you rebuild a 15g to a 18t the turbine itself is not bigger, its the inside internals that are different like the turbine wheel etc?please inlightin me on this matter,before i call the guy back again and sound like a dumb but...lol.thanks.

i thought for sure that the exhaust and intake ports would be bigger for sure,so im confussed!

The main thing is the compressor wheel and housing. There are minimal differences between the 15g/16t/18t/19t turbos as they're all in the same TD04 family.
