A 4g15 in basic trim should put down 92 HP, a 4g67/4g63 will be around 120-130 HP in stock trim and maybe more when it comes to a knock sensor higher compression GTi motor (1.8L Euro).
The custom exhaust header would help, but it would also move your power band up in the RPM range. Make sure you get to see some dyno sheets for support, from where ever you can find them. Basically losing some bottom end and gaining more flow on the top end. Probably won't be too bad, just depending on how large the collectors at each cylinder exit point and the style of exhaust, like 2x2 down to 1, or 4 down below the oil pan and combining to 1 collector. The 4g15 used an interesting setup to get some decent midrange, but the 3 valve head just can't flow anymore to allow power up top. It is the single biggest hurdle with the motor. That and the head gets super heated.
4G67 and 4G63 have an entire aftermarket of stuff catering to them, mainly 4g63 but so much stuff is interchangeable, that it keeps the 4g67 alive too!
You could conceivably take a 4g63 NA motor up to the 150-170+ HP mark, but it will cost you what you would have paid to acquire the 4g63t and get it up and running, in tip top shape. NA running maxed out or the 4g63t running low boost and capable of so much more. Doing the NA motor will require some custom machine work (porting), pistons, extrude honing of the intake manifold, intake/TB work, injector change ... maybe and then require tuning via SAFC or similar splice in device to fool the ECU into working with custom parts. The list of headaches goes on. If you get an early style 4g63t motor, all electronics can be easily converted to newer facelift (USDM 91+) style parts where the harness plugs in right at the ISC, TPS, CAS, etc. Otherwise you have 1-2 years of available parts to search for when something goes wrong. Most of the cars sold were the newer versions and have more support sitting on the shelf. The don't make an EVO3 turbo anymore, but there are many clones that would work for quite some time. Lots of small 16g (Galant Cyclone type turbos) still around and 16G (big) turbos too. All this to say that the factory 14b puts out 190HP in it's lowest form of trim at 12PSI boost at the turbo. It then bumped to 210-220-240ish, and then you get to start fooling around with later model parts, because they all (mostly) got better with time. Intake manifolds, cylinder heads, exhaust manifolds, 02 housings, black top CAS's, black top 450cc injectors, convert the injector clips to easy-press-to-release style and never break the clips again, etc etc. These are all things I have looked into as my car grew. I still have very basic parts and with an unknown AFR on the dyno (on a 14b with a bad WG flapper) the car put down 168HP to the wheels running a tank of 94 octane, and a super small Galant VR4 intercooler (USDM model - not JDM, as it was much larger like EVO's).
Long story, but if you have the time to build a motor on a stand and add a few wires to your harness (or splice in another one - harder), then it would be ready to go in one shot instead of pouring over things after the fact in tight confines like the C50 engine bay. It took me a couple hours to install belts .... I need not say anymore because I try not to think of the hard times! wink wink.
The community here does it's best to find parts as they come back into production and are readily available and the best part is that our site is free. I am a member over at the Philipines Lancer forum .... it in some ways, is not totally free. Made some nice acquaintances over there back a few years ago. Lots of good people over there, don't get me wrong!
Are those power ratings made at the engine or wheels? I think I'd be happy with 150hp more or less with DOHC. We would finally be checking on the engines soon if not tomorrow.
Regardless of what aftermarket engines we get, we would be getting the original harness that came with it so no problems with the harness unless we're adding more sensors. Would using the 4G67 or 4G63 ECU cause any problems with the tach and warning lights on the dash? Where could I also get the 4G15, 4G67, and 4G63 pinout so I can confirm everything is in the right place? The 4G63T I'm looking at came from a 1G AWD Eclipse and the seller still has the Stock AWD transmission and Intercooler with it. I'm not interested in the transmission since I'm not AWD(yet) but would the intercooler mount anywhere with little to no modifications? We still need to confirm if the 4G67 is high comp, for a cheaper option.
Are you talking about mitsulancer.ph? The community for the 3G CSM on there is practically dead... the last post was on June 21.
