I’ve seen a lot of questions recently regarding the conversion of a D16a6 to become a sohc WITH vtec. This setups is commonly referred to as a “Mini-me.” So I’m going to try and cover all the various angles to making one of these little D-series screamers right. NOTE: This isn’t a how-to article, it’s more of a broad ideas type pointer…for the down and dirty hands on, see Xtensive’s earlier article.
In theory, it’s very simple. Take a D16a6 bottom end and “just” bolt on a D16z6 or D16y8 head. Okay, if you have no idea why somebody would bother with this, raise your hand…For starters, more horsepower, more torque and it’s cheaper and easier than a complete engine swap.

The D16Z6 is the SOHC 5th Gen. Si and Ex engine pushing 125hp @ 6600 rpm and 106 lb.-ft of torque @ 5200 rpm. The D16Y8 is the 6th gen. SOHC Ex engine pushing 127hp @ 6600 rpm and 107 lb.-ft of torque @ 5500 rpm. These are extremely easy to find since allot ppl swap them out in favour for more expensive engines. ”
