EL Prototypes 3E-E intake.
The E series throttle bodies are all quite similar. They all have the same bolt pattern and are similar in bore size. However, only some can be interchanged due to changes in sensors and vaccum systems. If you are looking to upgrade, make sure you get a picture of the one you are going to purchase, and make sure it has the same sensors and vaccum fittings.

Between the E series engines there is a handful of intake manifolds to choose from. Unfortunately, if you have the wrong engine you could be completely left out. The 3E, 3EE, and 2nd gen 5E-FE have only one intake manifold avaliable to them. If you are looking for a differnet manifold you will have to get something custom made. Aside from those engines, all the intake manifolds are interchangable. That is great news if you have a 4E-FTE, 1st Gen 5E-FE, or 5E-FHE.

Head gaskets are a common way to increase or decrease compression between engines. Many of the gaskets are interchangable. Here is a chart of the compressed gasket thicknesses:

The E series rods are mostly identical. Except for a few JDM engines and the later (96+) 2nd gen 5E-FEs, they all share the same connecting rods. Here is a quick reference:
