So, I got myself thinkin'.... Compression and Air are good things. What do you guys think about doing an aftermarket cam and getting the head milled down a few thousandths to boost up the compression a few points. If you pull the head yourself it would only cost 30 or 40 bucks to get it machined down, and that should net you some more power while actually INCREASING gas mileage. And the cam should give it maybe 20 or so horses. So the way I figure it, we would be able to net about 40 horses from those two mods (CAM and Milled Head) for only about 300 bucks... cam might be $250 or so. My only problem is I haven't seen any camshafts for the 4G94. Can Anyone Help on that one???
What do you guys think???

 

yeah totally voids warrenty huh?

I say check it out. You already posted to it (both actually) and it's getting some decent input.

 

jeffm1999, read your post in another topic.

"Hey BAHA, you seem to know your ****. What do you think about a better cam that will open the valves farther and keep them open a little longer on the 4G94. And what about milling the head down to increase compression a couple points. I was figuring with the 2.0 engine those two mods combined would maybe net 35-40 more horses. Your thoughts??"

I'm not an expert on cam profile for its duration and lift, but I will try someone who has cam work on his car. The RPW guys knows this info wayyy better than me along w/ Dude in a mirage (has cyl head work done by DPR and RPW stage 1 cam for his evetual TC setup).

 

I am going through the other post with more specific info but for your information - we do have camshafts to fit the 2.0 Lancer right now. THe only info we don't have right at this moment is teh specs of teh stndard cams. Once we have that then we can sell both stage 1 and bigger camshafts.

Just a couple things I want to add:

First you need to do something to raise your rev limiter (redline is 6000 but what is your actual limiter set at??? 6200?) otherwise you will not want anything above a stage 1 camshaft...maybe a stage 2 if david designs it carefully to take into account the low redline.

A change in compression on a 2.0L 4 cylinder engine from say the stock 9.5:1 to a compression of 10.0:1 would net maybe 1-2% more horsepower and 1-2% more fuel economy. Milling the head within the max limits set by mitsubishi would probably not allow you to even get to 10.0:1 compression and you need to consider the change it will cause to your valve timing and you might need to "tweak" the timing belt tensioner to take up the slack.
