FA5 and FG2 Civic Si roll race shows the importance of a good tune.

Naturally-aspirated K24 engine provides solid baseline figures before boost is added to the mix.

We normally see K motors swapped into other Honda models, so this Volkswagen is a cool change of pace.

Building a Honda K motor for torque makes all the difference in an RSX.

No-lift shifting makes a sequential gearbox a perfect match for this turbocharged EP3 Type R track car.

Even though it is still being tuned, this K20-swap STi already took down its first victim.
