Ok I my brother we are working on a race car its the lowest class they got at the track but its real popular. Basically take a 4 cyl car strip it build a roll cage and then paint it yellow. Its called the hornet class. We got our hands on a 83 Chevy Citation for cheap. Comes wit a 2.5L 4 Cyl Fuel Injected. Now it handles fine but we need a bit more power out of that 4 cyl. Any low cost low budget ideas anyone? Its purely a race car so exotic non street legal ideas work. Thanks.
