whats the diffrence if any ?

 

..Well for one thing...I understand the "Overheating Issue" has been corrected..'94 + are very good..

 

Are you trying to or thinking about putting a 94 engine in a 93 es300?

 

yes and trans

 

the diference in the 94 is that it has passenger side air bags.... thats it.... idk about the engine....

 

94 and up models have the 1mz-fe engine that replaced the 3vz-fe. The manual transmission was dropped too. They also have a passenger airbag, and an outside temp display and and i think a beeping door lock/unlock feature w/ adjustable volume. And the "overheating" issues wasnt 92 and 93 specific, any engine with an iron block and aluminum heads can blow head gaskets. The 1mz is all aluminum.
