I am putting a 1998 federal engine into a 1999 California car. Will be using wiring harness, exhaust manifold and engine control unit from the federal engine.What else will I have to do to make everything work properly?

 

What engine type?

Why are you using the 98 wiring, etc and not modifying the 98 to a 99 using the 99 parts?

 

I bought this 1999 Camry with a bad engine.The 2.2L engine(120,000 miles) with California emissions spun a bearing. I bought a 1998 2.2L used remanufactured low milage engine with federal emissions which included complete engine wiring harness, complete intake, exhaust manifold. I am swapping the engine and computer(computer was on the car the engine came from).Are there any other problems I will encounter with this project?

 

Engine wise should be OK if you do as stated.

Take it the trans was automatic in both cars.

The 98 and 99 engine/trans/emissions for the 4 cylinder appear to not have changed between years.

 

Yes, they are automatics.Thanks for the support.
