as far as breakin, i did the heat cycle method.. and it took right at a gallon for the engine to finally break in. at first i was kinda upset with the motor.. had great power, but was running hot.. 250-270, and i didnt like that.. but when i hit the gallon mark.. it was like a light switch.. and the temps went down to the 200-210's.. and i was able to lean it.. and bang.. running round 225-230 with massive power..

These engines do take awhile to get fully broken in due to there excessive pinch. I had the oportunity to dyno a stock one that was fully broken in a few months back. I also ran the engine as well. Little softer on the bottom compared to some engines but has a nice smooth powerband and makes some good #s as well.

Yes that was a stock EVO III. The STI version just has tapered edges on the sleeve and a coated crank as where the stock EVO III has a uncoated crankshaft. And they say they hand fit the pistons to the sleeves and hand pick the parts.. But its all out of one batch I have seen the STI and the regular EVO III and the only real advantage I see IMO is the crank coating. Prevents rust and is a nice option. It also does has a drilled head and is a tad lighter.
