However, this makes no difference in power except that the bigger exhaust side allows for quicker spool time. Thats it! This is why mitsu incorporated a better impellar shaft made out of titanium because of the quicker spool. The titanium shaft decipates heat much better than the conventional stainless. All your 8's have a stainless shaft.

Why dont you ask Nick at Precision Dyno about all this, they have done more research on IX's than any vendor on here. He told me himself that the bigger gains comre from the turbo and the other part is the MIVEC

Im sorry, you haven't been heree long enough, when i joined this place was a little bit more civil, now, nothing but b|tching. I can't even get usefull info anymore. I mean just look at how many threads there were last week about the s2000 Vs the Evo! Amazing, wasn't it!?
However, if you feel that this thread is out of line then maybe you should do somethign about it and bring it to their attention? I think that wouldbe the best advice for you instead of butting into a thread you deem as inapropriate which only makes you an accomplice to the thread.

Like was already said, 10.5 hotside is standard on '05's. But there must be something else going on with the turbo as it requires an install kit to put on an older EVO. It isn't the stadard form of the other B16Gs. You can swap a IV turbo onto a VII or VIII no problem.

About the install part. Even a 05 turbo oil drain line is not as the 03 and 04s. The flanges are different and not aligned the same.

If I did this I would have spent thousands upon thousands and woudl get very little hp gains. I woudl encourage you to do the research yoursel;f and no have to ask someone.
I know more about turbos than some people who work for precision or innovate. Thats because I collect turbos. Its a hobby of mine. I can take apart and rebuild one properly very effectively and dilegently. I have turbos ranging from t3/t4 48 trims to super 60's and even all the way up to gt45's and t78.
I can gaurantee you that if you mic the turbine A/R housing that it is the same size as from the evo 8 03-06. The difference lies in the hotside which is where the impellar shaft is located. Why would mitsu stick a better impellar shaft in the same size housing? The diferences lie within the exhaust thats where the crucial portion of the turbo is. The compressor is just a compressor. However, everything is predicated on the hotside for the compressor to do anything. Now yes the compressor is what makes the big hp but in order to make the compressor side much more effective the hotside must be better engineered.

Third The compressor housing on the 9 turbos is bigger and your impellar shaft is not titanium. Basically you suck at life.
My point exactly

- The IX hotside is the same size as the 05 hotside (10.5cm^2)
- Only the 03/04s had the 9.8cm^2 hotside
- A larger hotside does NOT help spool. It gives more top-end power and slightly less spool
- The IX does NOT have titanium internals. Only the TME turbo has that from the factory.
- The IX DOES have a larger compressor housing. This has been shown and proven on many occasions.
- The IX turbo installed on an VIII DOES make more power. This has already been proven
- MIVEC only helps in low-end and mid-range torque, which does change the torque profile and provide more area under the curve, but it does not provide any assistance above 6k, which is when the MIVEC becomes in active. We hit peak WHP above 6k...
