Over the last 20 years we have been living in an era of leased engines. This done in both Formula 1 and Indycar racing. IMSA is heading in that direction as well. So you have a large supply of excellent race cars with no engine supply. Some people have solved that with motorcycle or raod car engines. Usually these are not very nice, nor are they fast. At Indy Competition Services, we can solve that. We can do conversions to proper high RPM, 600+ HP 4 cam racing engines. These engines are available from several manufacturers, Gibson, Judd and others are great choices for these conversions. Click on the link for more information onFormula 1/Indycar conversions.
