Ask a question about this product

The fourth-generation 4A-GE was produced from 1991 to 1995. It has silver cam covers with chrome letters, hence the nick name "silver top". This engine yet again features a completely revamped head where the 16-valve design is replaced with a 20-valve design. The Toyota Variable Valve Timing (VVT) is used in the intake cam for improved low rpm torque and economy, increased compression ratio (10.5:1), the valve angle was closed up to 37.5 degrees from the previous 50 degrees and the inlet system was replaced with a short manifold and four individual throttle bodies governed by an air flow sensor. Another large change from the previous 4A-GE engines was the inlet port angle, while the previous engines used an old fasioned curved inlet port the 20 valve engines used a very upright straight port. This engine produces 158 hp (118 kW) at 7400 rpm with 162 N·m at 5200 rpm of torque.
