What engines can easily fit into a Pontiac fiero?

Answer 1

The old school 2.5L 4cyl iron duke, or the 2.8L V6. Beyond thoes two which came from the factory, there are a variety of engines that CAN be put in a fiero. No engine conversion is ever "Easy", as there are always things that pop up. Some will need specialised adapter plates to fit the transmission, some will need special mounts. As with any engine swap, easy is a term relative to what your trying to do, your skills, and the tools you have available. Typically, ANY popular GM engine is "Easy" to swap with another GM product, meaning it can be done with a minimal of fabrication, however, do try and remember, that not all electrical systems work well together, for example, how do you plan to get the stock fiero tachometer to register the signal from a newer engine, when it works off a completley different signal? Is that easy for you to do? No? Well, some people find that the easiest part. Best advice, do your homework. Other than that, look into the 3.1, and 3.4, as I believe both of thoes blocks are externally identical to the 2.8 that came in the fieros. But again, do your research.
