Ueo's 2003 season car recorded 204 hp on an engine dyno. Ueo told us that the new car made between 230 and 240 hp on a chassis dyno because the engine dyno he uses has more resistance than a chassis dyno. An unrealistic load was placed on the engine dyno in order to make sure the motor will stand up to the stress that occurrs in competition.
While these aren't major numbers, I was still curious as to how he got 200 naturally aspirated ponies out of the old 4AG motor. I owned a 4AG, but my tuning was limited to an old-school TRD oil filler cap, and I never dynoed it to check the power increase. It's good to see that Ueo's mods are much more plentiful.
For the engine build, Ueo turned to Hitoshi Matsuda of Revolver in Osaka. Matsuda builds all of Ueo's engines, and he selected a '91 4AG AE92-kouki motor for this car. Matsuda bumped the compression and bored and stroked the inline-four with a late-model AE111 crank and rods and Revolver GT pistons and rings. Up top, Matsuda prepared one of his ported and polished SPL AE92-kouki heads with "Ueo Secret Type" prototype cams, Revolver valves, TRD springs, and Toda retainers.
Matsuda feeds his little beast with nothing less than a Skyline R33 fuel pump and a Sard regulator. Big gulps of air are brought in through a Toda air intake, a modified manifold, and factory AE101 throttle bodies. A Revolver header and exhaust handle the spent gases, and a Nissan CA18 catalytic converter was added for good measure. Finally, the brains behind this outfit are powered by a Tomei REYTEC ECU and ignition system. The '85 factory five-speed transmission is still used but an Exedy prototype clutch and Cusco LSD help send the torque to the rear wheels.
"I don't need power," Ueo adds. "It is all about balance. If I have more balance, then I don't need the power."
