lancer evo engine and our engine

[williamdsm]

What is the difference between the Lancer EVO engine and say the engine in my 91 GSX? They're both 4g63's right? And I hear many people say they are the same engine. I just want to know because the EVO engine sounds much different than a DSM engine when it revs. Just curious! =]

WTF

Which evo are you talking about?

 

[williamdsm]

I guess like an EVO8-9?

If you look at a picture of the engine from the evo 8/9's and look at your engine, you can clearly see what the difference is.

The engine is inverted.

I understand they look much different, and that will happen between two cars that are years apart. I was just wondering what the differences between the two of them are because they are both 4g63's, but sound entirely different. I don't know, I was just curious. =]

LANCER
EVOLUTION
Engine Type: Turbocharged and intercooled MIVEC inline-4
Engine Block: Cast Iron
Cylinder Head: Aluminum
Displacement (cc): 1997
Horsepower @ rpm (SAE net): 286@6500
Torque (lb-ft @ rpm): 289@3500
Redline (rpm): 7000
Bore and Stroke (mm): 85.0 x 88.0
Compression Ratio: 8.8:1
Valvetrain: DOHC 16-Valve

There is the specs of the Evo 9 4g63. Other then it being a completely different engine with the same engine code, how else do you want me to answer that?

I don't WANT you to answer, I was just wondering if anyone knew. =]

They are very different motors, not much other then the name is the same.

 

[Boostin91TSi]

They have the same block, however, the internals are different. Such as the cams, they are a different profile and compression is different. If you want, at Mitsubishi Parts, we do sell the Evolution VIII or IX motor complete with everything like turbo and manifolds for like $7,000. But in my own opinion, that is useless to you.

 

[ekanddsm]

I would say the key difference is in the cylinder head, being a mivec design.
The cams are swapped, along with a different head chamber design being the key difference. oiling in the evo 8 is probably more accurate then our dsm's.

But the combustion chamber on the head would be the key difference why they sound so much different. Different turbo setup(twin scroll) would shape the air different into the exhaust.

If your asking if you can use a evo 8 engine in your car, I would say yes, but you would have to have more dollars thans sense to do such a thing. Any evo making more than 400/500 hp needs new pistons, rod, rings, balancing just like a dsm.

the two engines are amazingly similar, anyone who argues otherwise should be ignored. the obvious big differences would be the inverted engine. this was done for better weight distribution on the evo 4. because the motor was inverted yet the intake and exhaust ports were kept on the same side, the cylinder head cannot be used on our cars. however, rods, pistons, valves, valve springs, headgaskets and many other parts arebin fact interchangable. it is very likely that the evo 9 valvetrain components cannnot be used due to the design of the mivec system

 

[williamdsm]

Thanks guys. I've read all your posts and it's pretty interesting. Thanks a lot for your time and knowledge! =]

 

[TurboTJ]

I have been wondering about this. Is it possible to swap in an EVO 9 engine and transmission? Is the drive shaft going to the rear diff in roughly the same spot? That would probably be the biggest problem. For the same setup, do late EVOs put down the same WHP numbers? Seems to me that they are higher for the same turbo...

The 4g63 engines on EVOs I-III are almost identical to the motors you will find in turbo DSMs. However, the 4g63 engines found on EVOs IV-IX are substantially different from your DSM's 4g63. Basically, everything under the hood is "flopped" or "mirrored". The timing components on DSMs are on the right, but EVOs IV-IX have the timing components on the left. Also the tranny is on the opposite side from our cars and even the turbo faces the opposite direction. Also of note, the EVO IX has Mitsubishi's MIVEC technology; our cars never had that.

 

[4G63_Attack]

I would like to add to this, if you install the new 4g63 in to the DSM it would be flip around. intake manifold would be in the front of the car and the exhaust would be by the firewall.

For what its worth, I posted this somewhat related info on EVOm a while back. EVO & DSM 16g turbos -- I spent like an hour working on that post.


Anyways, here is the main stuff I wrote that relates to this thread...

Mitsubishi Evolutions I through III have the same basic powertrain as DSMs (90-99 Eclipse, Talon, Laser, & GVR4) and consequently many parts are compatible between these two platforms. Of special note is the MHI EVO3 16g turbo that came factory on the Evolution III. This turbo is a very popular upgrade among DSM tuners as it is a cheap and powerful upgrade from the stock DSM turbos (the 14b and T25 respectively).

On the other hand, the powertain on EVOs IV-IX is substantially different from that of the DSM. Undoubtably the biggest difference lies in the reinovation of the legendary 4g63t motor. On DSMs and EVOs I-III, the 4g63 is transversely mounted with its timing components (cam gears, timing belt, etc.) on the right side of the motor and with the transmission situated on the left. However with its redesign in 1996, the powertrain layout was flipped or "mirrored" if you will. While still retaining its transverse mount position, the 4g63 was situated with its timing components on the left and the tranny on the right. In addition to the mirror image, the compression ratio was slightly lowered from 9:1 to 8.8:1. To compensate for the loss of compression, Mitsubishi Engineers introduced a new twin-scroll 16g turbo with the release of the Evolution IV that boosted the power output to 280bhp at 6500RPM.

I was waiting for someone to mention that. The Evo8 4g63 is very much the same, it's crazy. I know that aftermarket pistons for the Evo8 and 2g are the same part numbers, same with rods, bearings, etc... The only thing you can't use is a headgasket made for an Evo, but maybe you know something I don't Tstkl.
For the head, the valves, retainers, springs, etc all work.
