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.

“D16Z6, D16Y8, D15B7: If you have one of the lower and cheaper civic models, IE The Cx, Dx, Lx and If you’re looking for a cheap power increase while still maintaining stock gas mileage then the possibility of swapping in one of the higher model civic engines is right up your alley. 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. ”
