"Metallurgy - LAST MINUTE ADDITIONS

The internal components of the new Lancer Evolution's engine have been reinforced to withstand high levels of boost. The turbocharged version of the new 4B11 features a cross-drilled forged steel crankshaft that rotates in 4-bolt main bearing caps. Also unique to this engine are reinforced forged steel connecting rods that are attached to pistons unique for the application. The new engine's pistons are gravity castings made of a high strength aluminum material designed for durability, and quiet operation, and also include a unique ring package optimized for this engine."

"There's no doubt, Lancer Evolution enthusiasts have very high expectations for the new 4B11 engine," said Dan Kuhnert
"In terms of overall performance, refinement, efficiency and durability, we're confident they'll view the new engine as a more-than-worthy successor to the 4G63."

Now that we got that an engine that can withstand high level of boost and a 30k price tag. It sounds like a true evo

 

[Kooldino]

It always was a true evo. Now more people will perceive it that way.

Sucks that the pistons aren't forged, but then again, that's where Arias will come in for me.

4B11T > 4G63

 

[Jackygor]

This is definitely good news for everyone! now the haters can shut up!

haha, well no haters here, just on other evo forums

The engine sounds promising, Mitsubishi haven't forgotten their loyal 4G63 fans

 

[Kooldino]

I think if this motor was worse than the 4G63, mitsu fanbois would burn down their headquarters.

 

[DaemonSadi]

Woohoo, light that turbo up!

 

[Daesharacor]

excellent. betcha the aftermarket on the x will be huge, BT kits for everyone!

 

[GRK EVO X]

thats GREAT i cant wait to get one soon. This is going to be my 1st jap. car to buy and to modd it i dont really know alot about tunning EVO x. i only know about German modding i have a Benz C-class well modded .. i need some help on wich is the best tunners for the evo . im looking to modd in every way as possible

 

[FLK]

Once you own the car you will know it inside out i'm sure

This is a very good example of the new market that mitsubishi is trying to attract!

You will find japanese parts to be relatively cheaper.

oh and what FLK said.

that doesn't really say anything. "high level of boost" could mean whatever the stock level is, or even what the stock turbo can flow efficiently to. manufacturers talk about things in stock form not how they take to aftermarket mods. i can pretty much guarantee he doesn't mean it can stand up to double the power of stock output because there's no need for them to know if it will. not until it gets into aftermarket tuner's hands will its strength truly be known

anybody know anything about its ecu and programmability? will it be as easy on past models or will it take the mazda route and suck?

:+1:

Then again Daimler Chrysler had a hand in designing that engine. Ive had my SRT-4 push 27-28 psi before.

fixed. After all, the ECU is the only ford anything I know of in the Protege. Down with EEC-V!!!

 

[Kooldino]

The hardware is ford, the software is mazda.

The hardware wasn't the issue on the protege...the EEC-V has been hacked for many years before we used it. It was the programming that was encrypted and never got totally hacked.

That's mostly due to poor aftermarket interest.

The 4b11 may be a good motor but the 4g63 also has a steel crankshaft, forged steel conrods, aluminum pistons, six bolt main bearing caps,seven bolt flywheel ect. why talk trash about the 4g63 when the 4b11 is it's successor and the reason why we have evos period. :tmyk:

 

[Kooldino]

The 4b11 may be a good motor but the 4g63 also has a steel crankshaft, forged steel conrods, aluminum pistons,

The 4B11T has them as well...

six bolt main bearing caps,

No motor on the planet has a six bolt main bearing cap. If you've ever seen a main bearing cap, you're realize how utterly ridiculous the thought of six bolts in one would be.

Furthermore, the 4g63 has TWO bolt main caps, whereas the 4B11T has FOUR.

On top of that, it's lighter, has better valvetrain technology, has variable cam timing on the exhaust cam as well as the intake cam, doesn't need balance shafts, has a timing chain rather than a belt, is a square motor and more likely to rev, makes more peak hp and torque, has a broader power band, etc etc.

seven bolt flywheel ect.

I see. That extra flywheel bolt must work wonders. That must be why all of the 2nd gen DSMers swap out 7 bolt motors for the 6 bolt motors, right? Oh wait, no, that wasn't it...it was because the 4G63 had horrendous crankwalk issues.

why talk trash about the 4g63 when the 4b11 is it's successor and the reason why we have evos period.

I'm not trashing the 4g63, I'm just pointing out that the 4B11T is a better design on paper. Hopefully time will prove it to be a better motor altogether.

The 4G63 has proven to be a great motor over the past 20 years. Hopefully we can say the same about the 4B11T in as much time.

Welcome to the forums.

Maybe the case for 4 potters but.....

6 bolt main bearing caps are utilised on the LS1-LS7 V8 engines, (4 in the normal vertical position and another 2 horizontally further up, not ridiculous at all, it's extra strength) don't know of any others, but there must be more

Good to hear the 4B11 is strong, all of us will want to boost it up at least a little

 

[silvreclipse]

god this things will be deadly at the track.is he reffering to the six bolt engine from the 1 eclipses i hope not.

Never did much work on V8s, but I've only heard of them going 4 bolt splade on the mains. Obviously things are a little bigger, so it makes sense that they can squeeze more bolts in them.

I've built countless 4cyl engines, and I can't even think of where you could physically fit 6 bolts on there.
