You might also want to know that this engine is designed for torque, low end grunt, and not high end output. The small K04 produces incredibly fast spool up and high torque from 2,500 rpm to 5,500 rpm. But, on stock tune the throttle body starts closing at that point, boost tapers down, and power falls off. This is Mazda's way of protecting the small turbo's 5mm center shaft from excessive heat from trying to push it beyond its flow map. On stock tune above 5,500 rpm it just makes heat, like a flame thrower. The cam lobe profile is matched to the lower rpm torque curve of the turbo.
Aftermarket tunes make changes in timing advance, air/fuel ratio, boost and the relationship of those factors to each other in determining when to adjust one or the other to maintain or build power above 5,500 rpm up to redline, but this is not a high rpm peak power engine. In fact we recommend against going full throttle below 3,000 rpm, especially with power mods because the torque is so high that it can actually bend connecting rods unless you tune to keep it at stock levels. This is not a torqueless Honda relying on high rpm to make power.
I don't burn a drop of oil between changes, BTW, and don't think most here do either. I still have 180-185 psi compression across the board at 130,000 miles, down only 10 points from new 8 years ago. All engines will eventually develop loss of compression from ring and cylinder wall wear, but that does not appear to be accererated with this engine.
