4G63, the 4G93's are 1.8L Turbo, come out in the Lancer GSR's over here in NZ (1.8L AWD, Evo's baby brother).

 

That's what I was thinking with the aluminum roof, if they offer the GSR with a regular steel w/sunroof, that would be swell....

 

Never fear, HKS Kansai in Japan always gets the latest version of the Evo way before the public do because they help develop the car AND develop aftermarket goodies for it so when it DOES get released there will already be parts available. And I dont see the IX being any different from the VIII and VII etc in that aspect (HKS Kansai developing parts for it before it's even out)

 

Do you think the options for tuning will be condiderably less? Obviously without performance cams that would be a hinderance, but what about flashes?

Stating the obvious, the good thing about 4G63 is it's age in the hands of tuners.

I guess we'll just have to see what complexities the MIVEC brings to the tuning potential....

 

On the STI the variable valve timing always was and still is a huge obsticle to tuning

While it did give a slight spool up advantage, it was a real hinderance with ecu tuning and I wond up running my JDM STI C SPEC WITH AVCS with the AVCS unplugged when I went 11.88 @ 124 mph

A lot of these variable valve things on turbo cars do not have dramatic performance benefits and they do create issues for tuning

 

On ecutek flashing for subaru STI I have total control of the AVCS and I have not seem many gains from adjusting it from the factory settings

When adding bigger turbos with more lag it is helpful to adjust it slightly BUT most of the AVCS adjustment is RPM dependant and not load dependant

 

Well, I know RRM did a fabulous job of tuning the 2.4 mivec engine in the Ralliart for their Turbo car. I'm not saying it will be as easy to tune w/ the valve timing but what fun would that be if it was....heh

 

Just on a side note there are 2 versions of the 4G93 already in existence. The 1.8L mirage in the states had a SOHC version, while over seas there was both the SOHC and a DOHC turbo engine that others have mentioned. Of course that is the 4G93T

Also...
None of the above engines had MIVEC. There was a 4G92 mivec which I think was 1.6L and also a 2.0 Mivec engine but none of them were turbo'd and NA I was told they were very hard to extract any more power out of.

Ok stupid question --> So the Mivec is just variable vaulve timing aka VTECH for mitsubishi ?

 

yes

WADAD

 

yes^ each manufacturer likes to call it a different name

 

I wouldn't call VTEC variable valve timing. I'd call it a two position cam profile switch.... well, sort of.

 

VTEC stands for Variable Vaulve timing and electronic lift control

 

M - itsubishi's
I - nnovative
V - alve timing
E - lectronically
C - ontrolled

The aforementioned 1.6L DOHC 4G93 was Mitsubishi's answer to the B16B. I think it was rated as high as 175hp, by some accounts giving it an extremely high hp/liter rating.
