Although its Normally aspirated counterpart (4A-GE) used 5 valves per cylinder for a complete of 20 valves in its redesigned cylinder head throughout this timeframe, the 4A-GZE's cylinder head remained unchanged and ongoing to work with 4 valves for every cylinder for a complete of 16 valves.
Remember to enjoy the World-wide-web, the articles or blog posts, weblogs, and a variety of tidbits of technical facts collected in the final quarter century, and the Many of us that arrive to go to.

The Blacktop inlets at the head facet are also wider to permit for your larger inlet ports in The top. Be sure to see “Throttles”, “Head (Inlet experience)” and “Inlet manifold warmth insulators” for more information.
The combustion chambers involving the engines are very diverse when it comes to their squish spot. Even though their valve dimension and situation are similar the Silvertop includes a chamber using a squish area in each hole among the valves.
The left flywheel pictured is the earlier Silvertop layout whilst the appropriate may be the lightened Blacktop.
Ordinarily the belts can’t be swapped involving engines but when the complete tensioning method (16V / Silvertop: Oil pump, spring tensioner and tensioner post equipped to block) is altered / equipped then a Silvertop belt may be used on a Blacktop.
