Why the Honda H-Series Engine is the Best of the 90's

In this video we tear down a Honda H-series engine to see what’s inside and how it works. We also take a look at some of the strengths of this engine and some of its weaker points that made the H-series engine one of Honda’s signature performance engines of the 90’s.


The Honda H-series engines was used in the Prelude and Accord SIR since the early nineties. In this video, the H23 VTEC variant of this engine is torn down to understand its design and ponder upon its inner workings.

Of particular interest is its transverse orientation, with its timing side oriented towards the driver side of the vehicle as opposed to the more traditional passenger side for front wheel drive passenger vehicles.


Inside, the engine features sturdy bracing for the camshafts, a ladder frame reinforced crankshaft main bearings that also house tubes that form main oil galleys running in the engine, and an FRM coating inside the aluminum block.
