The Honda B18 engine is ideal for people who want somewhat more electric power devoid of sacrificing dependability. Searching for even more ability? The K20Z1 is perfect for people who want quite possibly the most electric power achievable in a fairly sized bundle.
The B16 is incredibly common amongst JDM tuners for one particular huge cause: horsepower for every liter. A modern Ford Mustang five.0L Coyote engine outputs around 420 horsepower, putting it 84hp/liter, this is sort of an impressive feat.

All of the key distinctions concerning the two engines crop up from Honda’s makes an attempt to enhance both of those engines based on the variances in engine traits. Allow me to check here make clear. Going again to The truth that the B16 is surely an oversquare engine and also the B18 is surely an undersquare engine, Honda optimized the internals of equally engines to match their solid factors.
Due to the simple fact that almost all of the Honda B18 engines we received from the US lacked VTEC, The most widespread modifications for those who have non-VTEC B18 variants is usually to swap a VTEC head onto their non-VTEC base close.
