Intake side woes
Okay...the Lancer isn't powerful to begin with but with the right touches, it can be made fast. This will concern the intake side of things. Cliff measured the stock throttle body (TB) at 63.5 mm. This hole is an entire 12mm smaller than the hole in the intake manifold, being 75.5 mm's. Another thing to notice is the size of the intake manifold itself. This thing is HUGE! It could possibly have a diffuser built into it, as to disturb airflow into the cylinders sapping power. The size also lends its hand to showing that there is a significantly smaller vacuum, and hence less air, being pulled into the engine. All these things make for a rather poor way to make power on the intake side. However...there may be a way around this...
Hypothetically (without
service manuals we have no definite way of knowing), it may be possible to switch in a larger (if it even is larger) Evo TB (due to its turbo nature) to perhaps make a bit of compensation for the woefully undersized stock Lancer TB. Another solution, and probably cheaper as well, is of course, a completely new Lancer TB, perhaps by some brand like Holley. RRM's bored out TB (+4mm over stock) is nice, but lacks an extra 8mm's of power making space. However, this is with good cause as anything over the 4mm requires the construction of a new TB. Now...another option is completely swapping out the stock Lancer manifold and TB and perhaps replacing it completely with an Evo manifold, injectors and all as well. More fuel and more air is always good. The Evo manifold is visibly smaller, showing that it has a much tighter vacuum with which to force air into the cylinders. This is all hypothetical but considering the Lancer (4G94) and Evo (4G63) engines are both 4G blocks, it may be possible...however, this is still all theory.

I'm a credit analyst. I'm sitting here looking at people's credit reports and reviewing, grading, approving, declining, stressing, eating, smoking, screaming, and pulling my hair out...and I find time to browse the boards too.
I like the idea of a head swap, but I dunno crap bout em.
Sounds interesting though. Gotta read. 
EDIT: It's perfectly legal to import Evo parts. Technically it's not even "importing" it's just uh..."international shipping" :P

We are talking about taking off the Lancer's complete intake manifold assembly and swapping it out for the Evolution's intake manifold assembly. Since RMR has both cars I'm asking if they know or could try said swap out. Yes you can import evolution parts. Although I'm sure they would cost you an arm and a leg, if the swap worked suceccessfully it would be the most benificial intake upgrade possible for the Lancer.
