What engine is in a 1993 Chevy Blazer?
The 1993 Chevy Blazer could come with a 4.3-liter V6 as standard, with an optional 5.7-liter V8 on certain models. The exact engine depends on whether you have the full-size K5 Blazer or the smaller S-10 Blazer, and on the trim level.
In this article, we break down the engine options available for the 1993 Blazer, noting variations by model size and configuration. Understanding the under-hood setup helps with maintenance, parts compatibility, and value when evaluating a used 1993 Blazer.
Full-size Blazer (K5) — 1993 engine options
The full-size Blazer shared its powertrains with other GMT400 trucks of the era. The standard engine was a V6, and an optional V8 was offered on higher trims and with certain option packages. Here are the engines you might find under the hood on a 1993 K5 Blazer.
- 4.3-liter V6 (262 cubic inches) OHV
- 5.7-liter V8 (350 cubic inches)
In practice, most 1993 K5 Blazers were equipped with the 4.3L V6, while higher-trim or optioned units could feature the 5.7L V8. If you need to confirm the exact engine, check the under-hood label or the VIN plate for the original specifications.
Compact Blazer (S-10) — 1993 engine options
The S-10 Blazer offered different powertrains than the full-size model. In 1993, the S-10 Blazer typically came with smaller-displacement V6 options and did not commonly offer a V8. Here are the engines you’d likely encounter under the hood of the 1993 S-10 Blazer.
- 2.8-liter V6 (173 cubic inches)
- 4.3-liter V6 (262 cubic inches)
Note that in the 1993 S-10 Blazer lineup, a V8 option was not generally available. The 2.8L and 4.3L V6 engines were paired with automatic or manual transmissions depending on the trim and configuration.
How to confirm your engine
Because engine configurations varied by market, trim, and production date, the most reliable confirmation comes from checking the vehicle identification number (VIN), the original build sheet, or the under-hood emission label. A VIN search through official GM resources or a trusted dealer can confirm the exact engine in your 1993 Blazer.
Additionally, you can compare under-hood stamps, exhaust manifolds, intake plenums, and badges to verify the displacement and family (for example, “4.3L V6” or “5.7L V8”).
Summary
For 1993, Chevy Blazers offered two major powertrain routes: the standard 4.3-liter V6 with an optional 5.7-liter V8 on the full-size K5 Blazer; the compact S-10 Blazer typically offered 2.8L or 4.3L V6 engines, with no V8 on that line. Engine availability varied by model size, trim level, and production date, so verifying with the VIN or under-hood label is the best way to know the exact engine in a given vehicle.
Summary: The 1993 Blazer’s engine options reflect two distinct model lines—full-size K5 with 4.3L V6 or optional 5.7L V8, and the smaller S-10 Blazer with 2.8L or 4.3L V6. Always confirm the exact engine on a specific vehicle via VIN or factory labels.
