Meet the Team at Hi Comp







 Joe DiGiorgio is the owner of Hi Comp performance. Twenty five consecutive years in the trade, and sixteen years running Hi Comp performance, there isn’t much he can’t do when it comes to your car. Dyno tuning EFI and carby cars, race engine building, cylinder head porting, servicing, repair and diagnosing is all in a days work for Joe. His dedication to giving you the best possible service has become his life’s work. Joe knows that your car is more than just the sum of its parts. He is ready to take your car to the next level, if only just a small job like a camshaft change or project managing an entire rebuild for street or race, Joe can, and will help you and your car realize your full potential.








 Johann is Joe's wife of 19 years and without her support Hi Comp wouldn't exist. Working in partnership with her sister Karen, she's responsible for even further behind the scences administration. She is also a great suppoter of Hi Comp's racing efforts and Hi Comp's biggest fan. Johann also comes to the track whenever possible to support our team.
