I highly doubt this is possible especially if the car is a daily driver. Here's the problem, Mitsubishi motors are not made for NA like hondas are. They cannot rev as high as hondas (needed for an NA 4-banger) and they simply are not as strong as hondas (talking about the 4G94 here). You're going to need literally every NA mod ever made and probably some custom stuff too. Since you want nitrous you'll need rods which are pricey. Here's the way I see it,
RPW header ~500$
Bored intake manifold 300$
RPW Quad throttle bodies 1000$?
RPW stage 4 cam 600$
P & P head 1000$
Rods 800$
High compression 11.0:1-12.0:1 800$
Exhaust 500$
Full standalone ECU 1000$
Fuel mods 500$
High quality nitrous kit (meaning at the very least wet kit maybe even direct injection) 1000$
With all this you'll end up with a car that is not streetable, it'll need race gas and it'll idle like crap if it even idles. I'm sorry but you bought the wrong car if you want NA, go get a honda if that's your plan.

Thats not to say you can't build a mild NA street car. But as aws just said, you never will be able to do with a 4g93/4 what you can do with a B or K series Honda motor. Take advantage of your car's natural ability to make torque.

Mitsu engines love air so open up the airflow and build the torque numbers. Dont worry about the HP cause thats not what is going to get you going. Mod for torque and then mod the suspension and transmission to sustain that new found torque.

 

^Glad you priced it all out for him! and like the comparison to Hondas (I can vouge cuz I got a sohc z6 that revs to 7800 all day long).

If you got the $$$ buy a more mod friendly car, if not...well enjoy what you got!

 

That's just a rough estimate for price too, it doesn't include tuning, install and the "dammit" mods that have to be done when things break. If I was going to build an NA import, I would go honda right away, I wouldn't even consider any other manufacturer.

 

I agree that with stock parts the 4G94 will never spin high revs. However, it has a solid block and with a modified bottom end that is balanced properly you can go beyond what is "normal" for this engine. Most people do spend this kind of time or $$ on this type of project. Most people go the "easy" route with a car that can normally be modified easily.

As for being a daily driver, putting that much work into the motor will reduce it to a track only ride. I think that with time and effort you can get 250 out of it. but it won't really be a 4G94 anymore.

I hope the machine shop is good at what they do, and you will need a really good tuner to map the ecu properly.

Good luck!

I like the use what your momma gave you torque comments!

 

it won't be all that fast a track car though. If i was gonna build a race only car i wouldn't even consider a lancer, not to mention an N/A lancer. If you wanna win races, a lancer isn't the car you want

I want to note the shop is my uncles, labor is free as long as I help and dont rush them for time. Price of steel is crazy right now but I think alot of my stuff will still be cheaper to make. I deffinatly see your point about putting this much money into it though. I may have to rethink this. I still have my 90 celica that I could swap a 3sgte into. Also have a 93 civic lx. Lancer is sexy as hell though.

 

Agreed again. The lancer just doesn't have the development behind it to be competetive.

Look at SCCA and NASA. You dont see people out there running Oz's or RA's. Reason being is the Mitsu didn't build them for that. Even though the RA is supposed to be the Perormance lancer it really isn't all that great. The motors are highly limited and reach a tuning max very very quickly.

Thats not to say you can't build a 400+ hp 4g93/4 motor. It has been done but those cars also only go straight.

The Mirage/Lancer chassis's more or less equate to being fun DD cars. You can pound out some good power with them to go out and have fun in the mountains and even track days, but to take one out and expect to win races against cars in your class (RSX, Civic Si, Mazda3 3 series BMWs etc) your ambitions outreach your grasp.

Hell even if you swapped in a g64 from an Eclipse you still are fighting an uphill battle because there is just no R&D compared to the H/A and Mazda camps.


I dont know if it was this thread or the other that pretty much mirrors this but as someone already said, dont build the car to beat other cars. Its not gonna happen. Those other cars will still be streetable and you will be stuck with a car that you dont dare drive on the street cause it wont idle, uses race fuel, is so stiff it feels like you are in an ejection seat when you hit a bump, clutch gives you a cramp when you shift and is so loud you can't hear for hours after you get out.

If you want to win and are dead set on it but a K series Honda or a Mazda3/6 and then go from there.

 

You going to pay for all the dyno time to ensure that those parts that are being fabricated actually are working the way they should? Cause I guarantee you RPW built their header on a dyno along with their other parts.

Its not always the cost of the materials to make the part. Its the cost in R&D to make sure your parts do as they are intended.

 

The problem isn't the bottom end, it's the stroke. High revving engines typically have a short stroke to keep piston speed down.

 

agree with everything amby and mirage said. not worth it on a lancer... now if you built the cars bottom and top end and then turboed it to make 300+ whp... with lsd and the whole 9 yards I would say go for it. but n/a? nah

 

without a quad or dual throttle body you are never gonna touch 200hp, nevermind 250

 

Im not doing it so much as to keep up with other cars, hell I live in a mass of neon srt-4's and ss cobalts all running stage 3-4 so Im sure I wouldnt be the fastest, Im more doing it for the fun of the build and doing something differant. You cant tell me a 250hp Lancer running NA and sounds like a nascar wouldnt be sweet. It may be a bad idea though.

 

I think it would be cool but for the amount of time and money for that 'coolness" I dont think its worth it. If you were to take it to the next level with a turbo kit. I may say its worth it. You would have a decently fast car.

 

if you pulled it off, yes it would be cool. But realistically it would be pointless. You will still be getting stomped by most cars at the track and to drop that amount of time/money into a car that won't even be able to put up a decent race is also a waste.

not to mention the fact, getting a 250 n/a lancer is near impossible, i think the best N/A lancer around is like 130hp. its just not gonna happen. you would be much happier doing a custom turbo setup. with the resources you have then you may be able to build the first 400hp lancer. which is possible with a turbo setup.
