It's Official: 2006 Last 4G63, New Evo X Engine: 4B11T
I understand what you are saying, but Ferraris and Lambos also cost a little more too. The reason, I think, Mitsu has been able to get by with an iron block 4cyl for so long is that it is just a 2.0L 4cyl, it doesn't weigh that much. They could always overcome it with horsepower and the fact that the rest of the car didn't weigh that much. When you are building a Ferrari or Lamborghini a 2.0L 4cylinder just won't do. Its got to be a 3.5-6.0L+ V8, V10, or V12. If you build an enigne like that out of iron, its going to be much much heavier then a 4cyl so it becomes much more critical to lighten the rest of the car, or much more of a weight savings to use aluminum. Most of those cars are N/A too.
Safety regs have forced Evos to get heavier and heaiver to the point where using a aluminum block is required for them to make the car overcome it. Now they are tilting it back towards the center of the car and hanging the turbo in the back for better weight distribution. I am sure they are using more aluminum now more then ever, and with more power I am confident they will be able to improve the car over the IX as they promised.

One of the biggest factors in hanging a turbo off of the back is cat light off. They want that 0.005% (exaggerated) better emissions on cold startup and that's why the flip on a lot of these motors towards a exhaust manifold coming out the back, close to the firewall. To me, its stupid. Turbo packaging 'can' be much less forgiving there. I'd rather build a very smooth free flowing exhaust package with good internals, but long live the marketeers!
The pictures offer a lot of help in understanding what the EVOX is coming out like, but there is a lot not seen until one actually gets here.

ok guys check this out
this is the current picture of the engine of EVO X
flipped the motor or not ?
2.3 L ?

its flipped in the sense that if you flipped the motor around so the exhaust manifold is up front, it would look like a DSM motor configuration (with timing belt on the drivers side). I think that is what he meant.

Copied from an intelligent IX owner:
No 4G63T. They replaced it with a 2.0 I4 that's ALUMINUM and has a FULLY OPEN DECK. This means it can't hold boost at all plus the bottom end will be half as strong (one of the real benefits of the 4G63T is it's amazingly stout). The modification potential will almost certainly be crap. I can guarantee you a IX (or even an 06-07 WRX) with bolt-ons will rape it. Basically, it looks like they built a 2.0L 2zz engine and added a mild amount of boost to top it to 300hp.
Also, it has stability control that will come in and brake the rear wheels if the car begins to oversteer and breaks rear traction which will probably lead to slower lap times with good drivers because of the loss of ability to power over.

oh lord.. so the evo X will be just like the sti? Oh say it aint so. I hope like hell that It is at least sleeved or else, forget 10 sec stock block evo 10s. Plus the car is 200 lbs heavier. Does anyone know the compression numbers? Oh btw the appear to have switched form the advans to dunlop tires. If you look closely at the pics it shows dunlop on the tire wall.

Ummm .. when using alumimum as a structural element .. it doesn't end up being dramatically lighter. Fundamentally lighter yes .. but other factors such as heat transfer and corrosion resistance make it very viable for automotive engine use. I think that's what you're saying here .. just not entirely clear.
:BUT, i don't think the change will be any different from the Eclipse. Everyone will keep buying the nice 4g63 models for years to come, and there were plenty of 8's and 9's sold to fuel the fire; the X's and on will just sit in 
lots. Oh and school/stadium parking lots for all the cheer leaders.

He won't care what engine is in it (as long as the specs look good on paper and it's fast enough). Since it's going to be partially automatic, and to the non-informed still have the mistique of an evolution, it may sell like crazy for the first year or 2.

4G63 is definately a proven block there is no doubt about that. the new 4B11T may not be iron cast or closed deck but at the end of the day we still dont know about its potential. its all speculation at this point.

Just as bad as the death of the RB26!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Turbo is between the engine and firewall. Intake is in front on this new motor. That is why there is a vent on the hood at the back and (probably) behind the front tires on the front fenders.
This sucks IMHO. Maybe I won't give a fug once they start heating this thing up for us all to see. I want to see the turbo glow orange/white in front of the firewall

alot would be riding on mitsubishi doing well with the X. but if it looses purists to an increased market share, it will probably live with that quite happily.
producing a tune ready engine is not their goal. they aim to be a profitable entity. sad perhaps, but a reality of business.
