This is the timing belt needed for the hybrid 7A-GE that uses the 16 valve 4A-GE head and 7A-FE block.
This is a 116 tooth belt. Use only if you plan on using the 4AGE oil pump and tensioner with a 16 valve head.
The later revision 4AGE oil pumps are higher volume than the early 4A pumps and the 7A pump. This is a better pump option especially for high performance builds.
This will also allow you to run the Toda heavy duty oil pump gear.

If you want to run the 7AFE oil pump you can use this belt.
