As for cam..anything lumpier than stock is the go..but almost all cams will mean you lose low down driveability, which is real important on a daily driver. I said CA18DE..normally aspirated. I used to have one, and it sounded nice, I used the standard airbox, with the atmosphere side chopped out for more air input and more intake noise output
The Zxx stuff is too hard to find. Get a worked L18 from a 1600, the wilder the better. And fit that with a Stanza 5 speed. Read through some of the L Series in a 1200 articles. Starting a transplant with only the intake noise as an inspiration point, is not a good idea. Get the basics right and then go for the "nice to haves". A car in the garage with no motor is not a car. I know I don't need to tell you this.

But it's good to see you back into Dattos again. (Not that you ever lost interest).
