Chevy Citation Race Car Project
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.
This engine was a pretty popular race motor in the '80s.
The 2.5 in your Citation is an "Iron Duke" motor. There was a large amount of factory support for racing them in the '80s. Searching Ebay for "Iron Duke" might turn up some interesting speed parts. You can also buy new intake manifolds from Clifford Performance, camshafts from most of the major cam grinders, maybe headers but I'm not sure who sells them.
And here's a Fiero page with a lot of information about cheap tweaks you can make to an Iron Duke motor. These may be more relevant to a low buck circle track car than buying a carbed intake or other serious speed parts.
