So my buddy had a turbo which he claims is a 20g that he bought from a company which he cannot remember (this was 4-5 years ago). It's been sitting in his basement for a while and I can't figure out if its a regular 16g or 20g.

The marks on the turbo say TD05HR 16g6-10.5T, which to my knowledge is the 10.5 hotside evo 8 16g. The only way it could be a 20g is if it had a 20g wheel put in?

Is there anyway to confirm this for sure before i take the time to put it on my car. Did a company even sell a turbo marked as a 16g with a 6 blade 20g compressor wheel put in it?

(currently a evo 8 16g with a 9.8 hotside)

 

Yes there were the old 5 blade and 6 blade 20g wheels put into IX turbos. Turbochargers.com sold the 6 blade version

 

right but this is a evo 8 turbo..

 

maybe its like a custom turbo. i have a 9 turbo with a 20g compressor put it in. maybe he was talking something like that?

 

how would I check if it has a 20g wheel in it?

 

Take the compressor cover off and measure the small diameter of the wheel. I currently have a IX turbo with a 20g wheel and I built one for a friend in an 8 turbo as well. A 20G is like 52.8mm vs 49mm for a 16G.

 

Double post.

 

Post pictures of it

 

x2

 

any way we can get pics man

 

He also mentioned he had a FP 18 psi wastegate actuator put on, I'm fairly sure this is correct just by the color of the piece vs the color of the stock one on my car now. Can anyone shed some light from the photos?

 

That looks just like my mystery turbo in my thread in the engine/turbo/drivetrain subforum. Apparently it is an evo9 20G-6blade turbo. Mine runs good but I never ran a stock 9 on my car to know how it compares. Some say a stock 9 is better but my car runs great. I may swap my stock 9 on this weekend just to see if it is any better or worse.

 

I'm just looking for 400whp on a dynojet, I'm thinking this will get me really close

 

Bump for some more info

 

You can definitely make 400whp on e85. Don't know about on pump has though.
