What are the timing marks for a 1988 2.2 liter turbo Chrysler engine?

There aren't single, universally applicable "timing marks" for a 1988 2.2 liter turbo Chrysler engine in the way some engines have readily visible marks on pulleys. The timing system on these engines is more complex, relying on the engine control unit (ECU) and various sensors (like the crankshaft position sensor and camshaft position sensor). There's no simple visual alignment like you'd find on older, distributor-based engines.

To properly time a 1988 2.2 liter turbo Chrysler engine, you need:

* A factory service manual: This is absolutely crucial. It will have the specific procedures, specifications, and diagrams for setting the timing, which involves checking sensor signals and potentially using a scan tool to verify timing values. The service manual will also detail the proper sequence for installation of the timing belt (if that's what you're working on).

* A scan tool: A capable scan tool that can read and interpret the engine's data streams is essential for verifying the crankshaft and camshaft sensor timing signals are correct. Trying to time it without this would be a serious gamble.

Attempting to time this engine based on generalized information from the internet is extremely risky and could easily lead to engine damage. Use the factory service manual. If you don't have the skills or tools, a qualified mechanic should perform this procedure.
