Donovan's Dodge Garage- 2.2/2.5 N/A EFI database
Overview- This page is for the upgrade and modification of the *NATURALLY ASPIRATED, FUEL INJECTED* Chrysler 2.2 & 2.5 SOHC engines produced between 1984-1995. I'll be frank in stating that there isn't a lot out there for these engines and the factory never did any research into making them go fast because they had the turbo package.
