1989 Crx Si Sohc Zc
Currently I have a Sohc Zc (The non-vtec version.) Yes, there is a vtec version available, look it up.

The problem I have is that I think I messed up my valves a bit doing the timing WRONG and now they are clicking. So, I am looking into which VTEC head to put on my car. I have a few choices. The D15 vtec head or a D16 vtec head, but which is better, which is easier, and which is cheaper. That, I have no idea about.

If you don't know anything about this type of thing, please don't say anything useless.

I'm only concerned about a few things.

- I don't know how to do the wiring for the Vtec.
- I want to use a smaller head gasket for a little more compression, but I'm not sure which type to buy.
- If I do lower the head a little tiny bit closer, are my pistons (Which I know nothing about the pistons in that particular motor.) going to be contacting the valves of a Vtec head?

Keep in mind, the Sohc Zc is almost identical to the D16.

I'm not sure of the differences between a sohc zc non-vtec and a d16a6 that is normally in an 89 crx si.

Any help at all on this topic, as soon as humanly possible would be great. I need to do this quick so I can start driving again.

Here's what's done on the car now so you can all get to know the new guy.

It's pretty comprehensive.
