E3
The E3 exhaust manifold is found on all Svo, Turbo Coupes, and Merkurs produced before 1986. It can be identified two ways. 1- is by the casting number is will read as followed E3*** ***** ** 2- is by the opening to the turbo it is a smaller peanut looking shape. As Seen Below
Notice the crack to the right of the opening. This is a common occurrences with these manifolds and a major reason why most upgrade to the more durable E6.
E6
Post 1986 Ford switch their production to what is referred to as the E6 manifold. Like the E3 it got its name from the casting number as well E6** ***** ***. This turbo can be ported to some adequate efficiency.
The E6, as you can see has a considerable difference in the opening to the turbo compared to the E3. It is also less prone to cracking, although it does happen.
There are other alternatives to the E3 or E6 manifold.
