13.0:1 Ethanol Powered 4G94!

It's alive folks!
Still lots of tuning, testing, modifications to come, but the biggest news, and greatest news is, it's alive! As expected with a ported head, custom cam, and jumping from 9:1 to 13.0:1 there was a noticeable gain. Especially in torque. Right of the box the throttle response was 100% better. The car certainly feels like it wants to jump up and go.
Special thanks to the following for their help:
Delta camshaft, who built a cam specifically for our odd ball application: http://deltacam.com/
Wiseco Piston, who also worked with us to build 13.0:1 4G94 Pistons: http://www.wiseco.com/
Rad Coatings: Who made the matching blue valve cover: http://radcoatings.com/

NICE!!! I am looking forward to seeing some dyno numbers from this beast. 200+whp from an NA lancer would be a fun ride for sure. One observation though is that maf adapter looks like a nice bottleneck right off the gate. Why not get one a little more open since you have the porting job on the head already done?

Thanks! We're real happy with it so far! Initially just happy that with help from Wiseco and Delta, that we could fit all that piston and cam inside one little motor!
Anyhow, your observation is correct, the intake sucks (or doesn't suck, depending on perspective), the entire intake will be reworked in time.
There are two primary factors at work that make this car unique, and dictate the build path: #1, It's a rally car. Reliability is paramount, any amount of power is useless if it can't prove reliable enough for stage rally. #2, As I know it, almost certainly at least in North America, no one has tried a set up like this on a 4G94, so we have little base knowledge to go off of.
With these considerations, every attempt to incrementally modify the car is taken, we don't want to make to big of steps. This greatly helps us trouble shoot, and collect more info about each modification along the way.
For example, right now it's running on a stock ECU, just larger injectors installed to compensate roughly for the increased fuel demand of ethanol. This way we simply took a known running motor out, and put a unknown motor in. There were no questions of ECU's, throttle bodies, map sensors, etc. If it didn't run, or had issues, we would know exactly where to start looking. Next, a stand alone ECU will be installed, so we can start to maximize the set up we currently have. After that, new intakes, throttle bodies, and headers are all in the plan.

Ecuflash is a great tool for stock ecu tuning and literally makes the ecu a stand alone setup. I have a hybrid evo rom I flashed into my stock ecu so I could properly tune it with the turbo. However you being na that may be tricky with an evo rom and the stock lancer tables are just too small to properly tune. All depends on how fast you want this tuned and running though ecuflash in general can be tricky. I guess that is the nice thing about aftermarket stand alone systems though they are well documented

Great work as always. I think we will need a video of this beast running at some point, or I will need to make the drive up and check it out.
