Well, if you're going to get the cam, then you also need tuning, and the dollars run pretty fast...
If you're getting a vtec head, you also need the ECU and wire it.
If you can do all this yourself, and have the money to support it, I would probably do the Bisi cam.
But it would require getting a tuning system and some dyno time.
Also, remember if your going turbo later, you might have to replace the cam again, depending on its specs.
I don't know anything about your setup, but if you have a stock intake and exhaust manifold,
they would NEED to be replaced to take advantage of the cam.
The design of those items are horrible on this engine, power wise.
You would also need some 240cc injectors (from an Y8 or just about any MPFI Honda except the D16Y7 and Y5 I think).
So, you see that once the ball starts rolling, it quickly builds up.
I have written this based on my limited experience, and without any knowledge of you who started the thread.
You may already know all of this, but I hope it will help you decide.
