2.4's are best had out of stratus/sebring/cirrus/breeze, etc. The cloud cars are littered with them. EFI control would have to be aftermarket if you wanted boost. Costs for everything add up seriously fast. Motor build, efi controller, new fuel system, extra $ if you want to convert to turbo, etc etc etc. Everything adds up very quick. If the $ is tight, you are probably better off building a 318 or 273 if you can find one. Fuel mileage will be down considerably, but would leave your other funds open to converting to an o/d 4sp, redoing your rear-end or whatever else. Plus efi and a custom motor install is a lot of work.
