I heard that the new lancers have this crap called a 4b11. Apparently the new evos will have this same engine just force inducted.
Can n e one fill me in on this.
If its true, I'm kind of excited. Finally we won't be associated with Evo owners anymore. I can't stand the people who drive those cars. Airheads w money have no place in the dsm world.

Yes they use a 4b11 for the new motors they are putting out about 500hp with no mods and the have a chain and The 4B11T is the first engine in the Lancer Evolution series that uses a die-cast aluminium cylinder block versus the cast-iron block used in the previous turbocharged 4G63, also the 4g63 is not in production anymore they are stoping it. its been used for about 24 years I belive, but yes there is alot of info on google.

Negative. They are not putting out 500hp. That would make the new Evo's "fast." Brother's bolt on 16g pump gas GST pulled some cars on it on a closed strip out here in the sticks. Evo X's put down around 220whp stock. STM just bought one and is doing some modding to it as the first Evo X from their facility. If you also haven't heard, Evolution production is done. No more Evo's will be made.
 
Here's all the info you'll need:

Peak power and torque figures of 206 kW and 422 N·m are for Japanese market Lancer Evolution models[5] and figures of 217 kW and 407 N·m are for US market models.[6]

The 4B11T is the first engine in the Lancer Evolution series that uses a die-cast aluminium cylinder block versus the cast-iron block used in the previous turbocharged 4G63 engine that powered all previous models. The engine weight has been reduced by 12 kg (26 lb) compared to the 4G63, even with the addition of a timing chain instead of a belt and MIVEC continuous variable valve timing on both the intake and exhaust camshafts (the 4G63 had MIVEC valve timing & lift switching type on the intake only). A revised turbocharger offers up to 20-percent quicker response at lower engine speeds compared to previous 4G63. The 4B11T offers a broader torque curve, producing more torque than the 4G63 at all engine speeds, helped by the engine's square bore and stroke design (both measure 86.0 mm). Redline starts at 7,000 rpm, with a fuel cutout at 7,600 rpm to protect the engine.[6]

A semi-closed deck structure, an integrated ladder frame and four-bolt main bearing caps contribute to engine strength, durability and lower NVH levels. Unlike the 4G63, the 4B11T does not use a balancer shaft. The semi-floating pistons of the 4G63 have been replaced with a fully floating pistons for the 4B11T. Aluminium is also used for the timing chain case and cylinder head cover. The engine features an electronically controlled throttle, an isometric short port aluminium intake manifold and the stainless steel exhaust manifold is positioned at the rear of the engine. The use of a direct-acting valvetrain eliminates the need of the roller rocker arm configuration previously used in the 4G63. The 4B11T features built-up hollow camshafts and its valve stem seals are integrated with the spring seats. The internal components of the 4B11T engine have been reinforced to withstand high levels of boost.[6]

I don't know where you got this from but this isn't true, stop spreading false information.

Thank you graciously for this insightful input on a 3-1/2 year-old thread.

I'm sure in this amount of time the O.P. could have researched every working part of the 4B11 and become an expert himself.

:rolleyes:
