Velocity Factor – Mitsubishi 4G63 High Performance Engine Building

At Velocity Factor, we often do full performance engine builds.  A fully built motor is a great way to maximize power, add strength, reliability, and take your performance to the next level.

Velocity Factor is your source for South Florida Engine Building.  We can build the engine in your Evo, STI, MazdaSpeed 3, or whatever other car you drive.  We have experience building 4G63, EJ25, MZR, and many other motors.

The pictures above show a 4G63 Eclipse turbo motor.  The expected power output is 500hp.

For this build, we are using forged parts from JE, Carrillo rods, Ferrea 6000 Series valves, GSC springs, ARP head bolts, and metal head gasket.  In addition to using these premium components, the head has received a port and polish job.  The engine build is then fully balanced and blueprinted, then torqued to spec by our trained and talented technicians.

To give the engine bay a touch of class and an attractive appearance, the valve cover has been custom powder coated with a candy blue finish.


If you or anyone you know are interested in taking your car’s performance to the next level with a professional engine build, please don’t hesitate to give us a call.  Our number is 561-395-5700. We are open Monday-Friday 10:00-6:00EST, and Saturday 12:00-4:00EST.
