A'PEXi 1992-1995 Civic EX/Si
It's no secret that the 1992-'95 Civic is an all-star when it comes to customizing. Civics of this vintage can be found on-line between $4,000 and $10,000 and we are sure many can be had for less in traditional newspaper classifieds. These are OBD-I controlled powertrains, which are easier to deal with and tune. And you can get a hatchback.
The D16Z engine is a gem. It's factory rated at 125 hp at 6,600 rpm and 106 lbs-ft of torque at 5,200 rpm. The powerplant is a VTEC, single overhead cam design that has proven its mettle on the street and at the strip.
A'PEXi USA developed its kit around an IHI AX53B60-P18 ball-bearing turbo because it provided the best combination of spool-up and top-end flow. The insurgence of ball bearing center sections has dramatically increased the versatility of modern turbos. With the reduction of friction provided by the ball bearing center sections, turbos can run bigger housings/wheels and produce more flow at higher engine speeds with out sacrificing as much responsiveness on the bottom end. The A'PEXi kit includes a cast-iron manifold that has superior durability than tubular manifolds. Fuel enrichment is handled by a high-capacity pump and adjustable regulator. A Power Intake filter kit, the appropriate plumbing and all necessary mounting hardware round out the kit. On the optional side, A'PEXi offers a GT intercooler and fuel system upgrades. For our testing purposes we will evaluate the stock non-intercooled kit and the upgraded front-mount intercooled kit.
