Early on in my build I really started to regret buying the stock Evo, there was something about the color of the powder coating that drove me nuts and I really hated looking at the motor. I started to think about options, do I sell? just deal with it and be disappointed? or do I do something about it? I decided that before I do anything the market wasn't real strong to sell and figured I really didn't have much to lose. I removed the push rods (was installing and Andrews Cam anyway) plugged all the holes I could and went to work. I dragged the motor outside and sprayed the motor down liberally with a general paint stripper I bought at the local store, within minutes the powder started to bubble like you wouldn't believe, I gave it some time and re sprayed the areas that I missed the first time around and within probably 45 to 60 minutes I sprayed the motor down with my pressure washer (med nozzle not the jet stream). I was amazed at how easy it was and how good the raw motor looked. I instantly knew I made the right decision and knew what I was going to do next. I had a wire brush wheel that I adapted to my Makita grinder. After I used my lawn blower to dry the motor off I sprayed the motor down with WD-40 and used the brush to lightly brush the aluminum. Note: this is fucking dangerous and you have to be careful go with the rotation of the grinder, wear heavy gloves like welding gloves, eye protection and be fucking careful. The first time around I got a nice deep cut down to the white meat! I included some pics of the final product which for now I'm pleased with.
