Here's why:
* Basic Compatibility: Both years used the same basic 2.2L engine family. The major components (block, head) should be very similar.
* Differences: There might be minor differences in sensors, wiring harnesses, engine mounts, and potentially the exhaust manifold or other ancillary components. These differences arose from ongoing updates and revisions during the production run of the S10s.
* Challenges: You'll likely need to:
* Transfer over necessary components: Expect to swap over your 1995's engine harness, computer (ECM), and possibly other peripherals. Directly using the 1998 harness and computer may not be compatible with your 1995's system.
* Address potential mounting issues: Though likely similar, you may need to modify or swap some engine mounts to ensure a proper fit.
* Exhaust system compatibility: The exhaust manifold may need to be swapped or adapted.
In short, while the engines are related and share many parts, it's not a simple swap. It will require some mechanical knowledge, potentially some fabrication, and the transfer of components from the 1995 to make it work. You'll need to compare parts diagrams and possibly consult with a mechanic experienced with S10s to assess the feasibility and potential challenges more accurately.
