Definately don't push it to 30psi. When I got close to 30 the shaft snapped and I went home on a flatbed.

16g is going back on and 20g-9-6 is now for sale. I don't wanna push this thing to 30 or so PSI to see the real gains. I pushed the 16g on 110 octane and 23 psi and did 325hp 325 tq.
This 20g only did 317hp and 307tq. Maybe its not even a 20g-9 but just a evo9 16g. I don't know enough to look at it and determine the difference.
I started the thread to see if what I got is a not the real thing. It doesn't seem to me that people like this turbo either way.
There is so much confusion when it comes to the naming of these turbos. The Evo IX turbo is a 16g (that is what it says on the spec sheet), yet people on here call it a 20g. I really do not know why people do this. There was a guy who posted pics (in show and shine) of his uninstalled 20g turbo and the stamping on the turbo said 16g, yet people were calling it 20g.

This whole naming thing is a total mess. I am totally confused with all the names being thrown about the 16g and 20g. I would love some clarification as to when the 16g becomes a 20g and why do people persist on calling a 16g a 20g when the stamping says otherwise.

Muscle car guy - "That thing got a big turbo?"

Me - "Oh, it's just got a stock style turbo, like the ones that come on the new '06 model . . . it's not that fast. Wanna race??"

No, people do not call the IX turbo a 20g - it's a 16g. It becomes a 20g-9-5 or 20g-9-6 when they put a 5-bladed or 6-bladed 20g wheel inside of it.

There's a stamping that says 16g, or does it say TD05H?

TD05HRA-16G6mC-10.5T is what my 6 blade said. The stamping is the same because the housing is the same.

The stamping says 16g.

https://www.evolutionm.net/forums/sh...&highlight=20g

Look at the first pic. It is the one posted here by justchill, only clearer. You can read
"TD05HRA-16G6mc-10.5T"

Now check out this section of the spec sheet from Mitsu for the Evo 9. It says the turbo is a "TD05HR-16G6C-10.5T."

So both the 9 turbo and what justchill refers to as 20g have stamping that says 16g.

Correct, because a '20G' retains the factory 16G housing. When a 16G is converted to a '20G', only the internals are changed. The housing is not restamped "20G".

A "20G-9-5" refers to the upgraded 16G turbo sold by Buschur Racing, which uses an EVO IX 16G housing, and has a 5-bladed compressor. The EVO IX 16G compressor housing by itself provides a bump in power over the EVO VIII housing.

A "20G-9-6" refers to the upgraded 16G turbo sold by everyone else. This turbo also uses an EVO IX housing, but has a larger 6-bladed compressor, is cheaper, and is the one whose performance is suspect.

Yeah for the 18th time it uses the same housing as Ted and I both have said. The only way it's going to say 20G is if they grind the stamp off and restamp it... sigh

There is no such turbo available twin scroll off the shelf. It is a custom compilation of wheel and machining by FP and BR.

IMO, it is still deceptive to call it 20g. It is a 16g with a different compressor wheel. What else is changed aside from the wheel?
