Evo IX- Piston rings....
Evo IX- Piston rings....
I just finished watching the Best Motoring Vid on the Evo 8 vs 9. They say the 9 has 2 piston rings instead of 3. Will this be a weakness from the aftermarket tuning aspect? Can this limit max boost pressure it can withstand before allowing blow-by? I see there is a lot of attention to the Mivec being a problem, but what about this?
i know personally when I built up a motor on my domestic, I opted for a 3 ring system since I was turbocharging it. . .conventional knowledge holds more rings=less blow by=less oil consumption, but they're purporting 2 rings=less oil consumption, so I'm just confused with the Mitsu engineers on this one. . .

From the Singapore Brochure thread.
"Detail improvements have been made to
increase engine durability and reliability.
The addition of intake temperature and
pressure sensors in the intake manifold
has raised air/fuel charge flow and
ignition timing precision."
Now won't these sensors be another hurdle for tuners? For instance...You install a blow off valve that doesnt open and shut exactly like oem. The new manifold pressure sensor picks that up, and Ding a stupid CEL. Thanks.

If you're just going to buy it, drive the crap outta it and not change anything, the IX is the way to go.
More obstacles to overcome... it will just take awhile longer (I believe) to mod the IX due to the new technology being added on to it... the 4G63 has been the way we know it for many years now... eventually the MIVEC 4G63 will surpass our level of modification, but not without some hiccups along the way.
Just my thoughts.

Is Mitsubishi going to use a whole new motor for the X? If so, I'd have to think that the tuners wouldn't be very interested in waisting to much time learning the quirks of a technology that was only used for one year in the Evo?

Best Motoring is not relative for USDM cars. I doubt that the USDM 9's will have those changes. The JDM MR has all sorts of changes to the engine over the standard 8, most apparent is a metal BOV. Does the USDM MR have a metal BOV...NO!
Where is the AYC??? Not on the USDM car. Where is the Rear Aero bumper??? Not on the USDM cars. I would bet that the 9's have the Mivec head, the new turbo and that's it.

The stupidity is giving me a headache. Please everybody read this and I hope you come out with some factual knowledge.

If you have an atmo BOV mounted before the MAP sensor it will actually reduce CELs. MAFs and BOVs dont mix well. So Mitsi is doing you a favour.
