Just bought a JDM 180hp Si Vtec 1.8 94 4dr
Has 80k on the clock about to do 600 miles before next oil change.
Whats the best way to drive it?
History of my SilverShadow: Gen3 JDM Integra Si-VTEC
The JDM Honda Integra changed generation in early 1993. The new model, coded DB for 4-door and DC for 3-door received a body revision and quad-projector headlights. The most significant change however was the engine upgrade, from the 1.6l B16A to a longer stroke 1.8l DOHC VTEC B18C with a new intake manifold. The B18C engine red-lines at 8000rpm and generates 180ps at 7600rpm. Although only 10ps higher than the current B16A, its bigger displacement and the special intake manifold gave much better low-end and mid-range making it more driveable over the B16A especially with curb weight being only moderately increased.
The new B18C intake manifold uses two sets of intake runners. During low and mid-rpm operations, the valves are closed and only the top set of runners are feeding air into the cylinders. After 5800rpm, the butterfly valves open and air will now be fed into the cylinders via both sets of intake runners. This new intake system works in conjunction with VTEC, which now switches at 4400rpm, to optimize air-flow into the cylinders at all RPMs making the power/torque curve of the B18C extremely wide and flat. Peak torque of the B18C is 17.8kgm at 6200rpm but torque output of the B18C is already near or at 17.0kgm all the way from approx 2500rpm right until the 8000rpm, a smaller than 5% spread for practically all operating RPMs !!

I spoke to Jakan Honda, Dan there said not advisable to race these cars by changing from 3rd to 1 to get power as it can harm the engine...
Anyone else know of this? He says he can tell from the sound if the engine has been thrashed or not...
