190e 2.3 to 2.3-16 conversion

[MercBoy]

Well, after exhausting the search program, I've yet to have my questions answered.

I currently have a 92 2.3 that I'm looking to get a little bit more perfromance out of. What would the best options be? If I didn't care about the air/con, how easily would it be to convert my 2.3 to the 16 valve version. I'm looking to spend between 1,000-1,500. Is that resonable for some small engine mods? I'd appreciate any help. Let me know what you've done to your 2.3s to get some more hp/tq

thanks.
