The K20A3 engine is often overlooked in terms of its performance. At Skunk2 we found that significant power gains can easily be achieved. Taking what we know from K racing engine development, we were able to develop several highly potent camshaft combinations for the K20A3. Because there is no VTEC on the exhaust camshaft, great care was taken in selecting lift and duration specifications that allow the engine to make power and still retain a factory idle. Our K20A3 camshafts feature ultra high-strength hollow iron alloy camshaft cores and cutting edge profile design. With the proper tuning, Stage 1 cams have yielded 17+hp on K20A3 engines and we have seen gains as high 28+hp on nearly stock K24A engines using Stage 3 cams.
