Isn't that an A20A engine? There isn't much aftermarket support for that engine as far as I know... it is a solid engine, but was never ment for speed. If you are really into it, send the cam off to Crane or Crower or some other company for a mild regrind.

I think Golden Eagle makes an adustable cam gear for it.

The B16A intake manifold can be ground down and redrilled to fit if your car is fuel injected.

The old JDM Accord gold top B20A should also fit if you want to swap. They are rare and very different from the 88-91 USDM Prelude B20A/B21A.
