6A12?

thats the only language i understand. Evo 8's are ugly, of course the motors are reliable.... unless u plan to do something pretty stupid with it. i doubt there is much difference between the 2...

The EVO VIII came out with Active Yaw Control, and I off the top of my head I think it was an Active Differential Control. Look it up in the Mitsy website and it'll tell you.

I've also heard the EVO VII was a bit of a flop and they hardly sold any. It maybe coz they didn't race that one in the WRC. Not too sure though?! Which EVO was in 2 Fast 2 Furious? EVO VII or EVO VIII? I think it might have been VII

Is the VII Joel.

Btw Active Yaw control had been standard since EVO IV & EVO VII does have Active Differential Control as well, it was the first EVO to have it

The improvement of EVO VIII over EVO VII are

1. 6 speed manual instead of 5

2. Upgraded water pump with larger water passages in the turbocharger

3. Active Yaw control had upgraded software to SAYC1 (only on GSR model)

They are small improvement on paper, but they made the EVO VIII a much faster & more reliable weapon on the road & track.

Dude the EVO IV had those, if u eva buy a EVOIV always make sure the AYC diff has been maintained.... most mechanics wont touch em so they get imported with fucked AYC diffs

They test drove the evo 8 on top gear leats night.

It versed a lambo and the guy was shocked how good it went. It was pretty much neck to neck.

Too bad we don't get that spec in Oz or anywhere outside UK

He said the car was awesome for 5 minutes then he went about the bad stuff bout the car (evo 8 400 spec) eg turning cycle, clutch and the lag......and there was heaps of it!!

The best way to go is to get the normal evo and do it up yourself. It cost around 80k for that spec EVO.

spend 25k on other mods i reckon.

Hold out for the EVO IX which has inbuilt MIVEC and is rated something like 400ps in stock form.

Yeah the EVO IX does have MIVEC but it don't work the same as the FTO's MIVEC.

Yeah the MIVEC in them are just for fuel economy & not performance.

What the hell is 400ps? If you mean BHP then the EVO IX is rated at 286bhp/213 KW

Why would they design a sports car like the evo to get better fuel performance. The Mivec must be inthere for more reasons then just fuel.
I would imagine it just isnt as agressive as the NA version and also not as high compression ratio. I would imagine the Mivec was also for bragging rights, varible cam timming is something the subbys dont have.
The Different cam profiles are proberly there to help turbo spool too

FTO338 · Post by **FTO338** » Tue Jan 24, 2006 8:58 pm

Actually Suby STI have Varible cam timming since MY04, so now Mitsu need to keep up with the "marketing" in order to justify why the EVO are more expensive then the STI...........ala MIVEC

I did not realise that, however as far as I can see the subaru AVACS is no where near as advanced http://www.drive.subaru.com/Win05_WhatsInside.htm
It doesnt use 2 different cam profiles

Wouldnt mind one of these babys

The mivec engine only adds 4 max hp, but 20nm of torque, so it wasnt just put in for fuel efficiency.
Though your right they are only just catching up

The MIVEC in the FTO is variable valve timing and lift, with the EVO its just variable valve timing alone, basically all it does is give the engine a better fuel economy, give more torque at low revs and widen the torque range, its the same with the STI and it works on the intake cam only, I think it is the same with the evo, The FTO's MIVEC works on both intake and exhaust.

Not that it matters much anymore, aren't the STi's going to 2.5L??

Nacho i think you have your facts mixed up between the Evo IX and the UK-only FQ400-spec Evo...

from what I've read about the new Evo's 4G63B, the MIVEC was incorporated to improve overall engine response using optimised camshaft profiles to leverage the torque generated by the quick-spooling turbo (so in a way Gavin was right)...

many journalists who have test driven the Evo has acknowledged that power is very smooth and responsive with the MIVEC, not like the STI's which are reportedly 'riddled' with lag (though still not as bad as it sounds IMO).

FTO338 · Post by **FTO338** » Tue Jan 24, 2006 11:40 pm

Even then the FQ400 is EVO VIII, but there is a FQ300, FQ320 & a FQ340 for the EVO IX.

Ohh & i take the new MY06 STI any day over the EVO IX
