Honestly though, when we all think Eterna, Galant hatch comes to mind, but say GSR and ECS FWD na 4g63 come to mind lol.

MIVEC is just valve timing, nothing special since MIVEC has been around since the 90s, they just didn't apply it to the 4g63 until the Evo 9 came out.
A later 4g63 conversion is not more modern its just a revised version of a 25+yr old motor lol.



Actually the 4G6 engine has its roots in a diesel engine from the 1960s /ubbthreads/images/graemlins/wink.gif

Have a look at the old 4G3 engines (Lancer Turbo) and the diesel engines in the L200 from recent years - they are based on the same initial design of the block and so does the 4G6 which shares lots of its design with them...

Mivec was already tested in the Lancer Turbo and Starion in motorsports - some of these cylinder heads ("sirius dash") even made it to the free world.

The mivec now used on most MMC engines is a completely different technology: phase shifting with only 1 cam profile.
The "original" Mivec used 2 cam profiles and interconnectable rocker arms (via oil pressure). on some engines even combined with single valve deactivation (MVV - mitsubishi vertical vortex) or even cylinder deactivation.


BOT:
We've converted several Colt CA and CJ to 4WD with evo drivetrain and also put a 4G93 DOHC from a CA into a CJ. The engine conversion isn't that complicated - the driveshafts and height of the engine dictate its position - so you really just mock up the engine into the engine bay until it fits under the hood and the driveshafts fit, then add the engine mounts...
This would be even easier with 4WD as the transfercase is another fixpoint so you have even less variation.

The rear axle and it's fixpoints have to be made on a car bench with tooling for the actual evo model you use the rear axle from. This would be the hardest part as the rear frame of the galant differs A LOT from evo/lancer/colt. colt and lancer were always quite similar underneath - so the frame crossmembers are in the same position at the colt to get the 4WD rear axle mounted on. The rear structure of the galant though is a completely different story if you want to use an evo rear axle...
The easiest approach (IMHO) would be building a tubular subframe (or modify one, e.g. the one from R4 kit) with all the mounting points for the suspension arms. thus the needed modification to the cars frame would be minimized (but the mounting points for the upper wishbone are still missing on the galant...)

Lancer EX Turbos were g62/g63 though, regular box types yeah came with 4g3x in them but not the turbos. Yeah I know the Sirius family is based of the Saturn motor family.

Quoting prove_it:
Evo X is still flipped and same as the EVO 4-9.



Not exactly true. Yes the Timing side of the 4b11 is on the passenger side. But it also has the exhaust manifold against the firewall and spins the opposite way. So, if transplanted, it would be oriented correctly. But, good luck with the motor mounts and transmission...

Evo X 4B11 still spins clockwise like all 4G63s and every other Mitsubishi engine.

The 4G3x made its debut in 1969 as a 1300cc chain driven engine and didn't share a great deal in parts with the later belt driven 4G32/37 which the 4G6x was very loosely based on. Common parts include the timing belt (for SOHC engines) and big end bearings. That's about it. The 4G6x is physically longer and slots more between the 4G3x and 4G5x in terms of size.

The first mainstream diesel from Mitsubishi was the 4D5x which was based on the 4G5x gasolene engines which came first. There was the 4DR5 before the 4D5x however it was installed in commercial trucks rather than passenger cars, SUVs or small utility vehicles. The 4D65/68 is of course based on the 4G6x engines which the gasolene variant did come first in 1980 (and was turbocharged right from the very beginning as opposed to other engine series).

Ugh. If people want an Evo, they should buy an Evo. Dash swap? Really?

I realize the transmission on the Evo 4-9 are stronger, but IMO it's not worth the engine swap for just a better trans, since you can make the same power with our "old" 4g63. There are other options with less headaches to deal with the weaker transmission.
