About the only parts I can't find for my 8 valve (H for '88, that was it in the States) are things you can rebuild like the distributor, as well as fuel lines and some of the fuel system stuff. The big items you can still get (cold start injector, warm-up regulator, idle airslide, oxygen sensors, fuel distributor and control pressure regulator, main injectors, accumulator) but others (hall sensor connector, fuel lines, some thermal switches and emission control relays) are getting tough.
Right now, I'm looking for a new red-capped thermal switch and a way to change the timing chaing tensioner and guides without pulling the motor. The chain's fine, but the tensioner is extended quite a ways.
If I were you, I'd look for an '87-'88 8 valve car in a junkyard and buy the whole car. A few years back, 150k cars with blown automatics were still plentiful, but now the price of steel has risen and the supply of 900s has dropped dramatically. That being said, I'd still go the 8 valve route, just take your time finding the difficult parts and buy spares as part of your conversion project. Just like how it's a good idea to have a spare air mass meter and idle valve for a 16 valve car, I think it's a good idea to have some 8 valve bits laying around, especially if they're going to be phased out. If you don't get a motor with the updated timing chain tensioner, be sure to swap that as part of your project.
16 valve pros: more power, better startups in hot weather and performance in cool weather, slightly lower emissions.
8 valve pros: no low-RPM dead zone, less reliant on wiring, fewer moving parts, simpler heater hose routing, more appropriate for your model year, better driver's engine, and the rock-solid reliability thing.
