Cam I swap a 1999 Toyota solara motor with a 2001 Toyota Camry?
Can I put a 2001 Toyota Camry engine in a 1999 Toyota
Adaptation isn't what it used to be. With today's computers and sensors, if you have the same model year and the same basic platform, the engines would have been manufactured the same. All components, including electrical and engine control would be the same. Accessories might differ, but you would be keeping those that came with the receiving car: air conditioning, cruise control, etc. Replacing an engine with one from a different year or a different platform, even though the Solara and Camry are really similar, would entail some modifications or wire harness supplements to work. The question isn't an easy one to answer other than the obvious "Liberty" is likely the only easy replacement car. Researching other cars for computability would be a nightmare.
