Sure.
The K20A in the DC5 Type-R and Accord Euro-R is a very high revving engine that, while it has a lot of torque compared to the B18C5 or the Celica GT-S engine, has a lack of torque down low. The K24 in the TSX is designed for better low end grunt than the K20A, giving it superior driving characteristics below 4k RPM. Also, the K24 is essentially a stroked version of the K20...it is very difficult to get more ponies out of this engine because of the long stroke, which would probably have difficulty revving as high as the K20A does if we want to maintain the reliability of the engine. I wouldn't be surprised if Honda somehow got another 40 horses out of the engine or added an IMA AWD drivetrain in a couple years, but that's that.
