3.8kg is pretty light, but you can get stuff almost as light without the Spoon price. You might not want to run such a light wheel on a daily driver either- I'll bet it won't hold up too well on the street.
Don't go to Wiseco's site- read up on ImportBuilders' site or shoot them an email. Wiseco makes MUCH more than what they list on their catalog. You can also use JDM DOHC ZC pistons- you can get a set for about $100, and they'll bring your compression right up to 12.0:1.
I really don't know which valves to recommend over the Skunk2s. Go search on your own and find some. All I know is that I keep hearing negative things about the Skunk2 valves, so I'd stay away from them.
Skip the pulleys unless they're just lightweight. Underdrives tend to cause problems. If you underdrive your power steering, A/C or alternator, the pumps and generator won't be working within their OEM specification unless you're revving up high. Maybe if you're going to be on the track all the time they would be nice, but on a daily driver you could cause damage to your car's systems. If you're looking at replacing the crank pulley, you really want to keep the OEM pulley because you don't want to toss the harmonic dampener.
If you're in Canada, the D16Z6 should be very easy to find. Just start calling junkyards in your area. The Z6 was available in all of the 92-95 Civic EX models in the US, and I think those are the same as your Civic Si in Canada. The D16Y8 could also be an option for you. They were in the 96-00 EX here, and your 96-00 Si. As for rewiring, you can run all your original non-OBD systems on either engine- just reuse all your old sensors and distributor, then wire in a VTEC controller to take care of the VTEC crossover and the fuel management. As far as shift linkages, axles and mount kits- all together those will typically cost you about $800 US, and to me, that's not just "a few hundred dollars more".
Both the D16Z6 and the JDM DOHC ZC have similar levels of potential. They both make about the same amount of power and torque in stock form. The major difference between the two is obviously the number of cams. The DOHC ZC is really nice with a turbo and no internal mods- most people can squeeze 200-220whp out of one without going inside to change anything. The same goes with the D16Z6- they typically make 200-250whp under boost with the proper setup and no internal modifications.
The DOHC ZC is easier to tune sometimes because you can independently advance and retard the cams, but all the aftermerket cams for the SOHC VTEC help take care of that. As it stands, the aftermarket for the D16Z6 is much larger, since the engine (and the D16Y8) was available in the US. You can swap in all sorts of OEM and aftermarket pistons to raise compression, get tons of different camshafts, buy valvetrain components etc. With the JDM DOHC ZC, it's very difficult to find parts for it. There are maybe 2 manufacturers that make cams for it- and even then it's almost always a custom order- nobody makes cam gears for it anymore, and there aren't any OEM pistons that can drop in to raise compression. The engine was last available in 1995- 1991 in any kind of decent quantity (the non-OBD version that you would want too) at all, and it was NEVER available in the US. I don't think you could get it in Canada either. Regardless, it is a good engine- and there are sites/forums out there dedicated solely to supporting it, but I would choose a SOHC VTEC over the DOHC ZC if you're planning on modding the engine at all. It's much easier.
The geometry of the DOHC ZC and the D16 engines are the same- all are 75mm bore by 90mm stroke. The pistons and rods are interchangeable between the D16 and DOHC ZC engines.
