	This is intended to clarify the differences between the two versions of the 20V 4A-GE engine. The earlier silvertop was fitted to the AE101 Corolla, and the later blacktop to the AE111. Both engines use one throttle body and five valves per cylinder. 
  
 
AE101/Silvertop (~165hp) 
 
    * D-jetronic based ECU (flapper type AFM) 
    * 10.5:1 compression 
  
 
AE111/blacktop (~170hp) 
 
    * L-jetronic based ECU (MAP sensor) 
    * 11:1 compression 
    * Increased lift in intake camshaft 
    * Different pistons 
    * Revised intake ports 
    * Revised variable valve timing 
    * Timing belt tensioner change 
    * Different throttle body to head insulator
