I know Campbell didn't ask about other tools, but after 7 years of racing VW's I've come up with a list of tools a VW IT racer might want to consider owning:
1. Fuel pressure test kit. Impossible to set the control pressure, diagnose fuel pumps, etc., without one. ~$120-140 but worth it.
2. Front wheel bearing & front hub puller/installer. ~$200 for the Schley, but if you hunt around you can find them on Ebay for less. I bought one for $35 that was for late 70's & early 80's FWD Chryslers. I just had to get one piece (correct size bearing die) made at the local machine shop ($25). The bearings and hubs are relatively cheap and should be changed out every 6-8 races anyway. This tool makes it a snap. Otherwise you're looking at $20-40 of labor at your local VW or car shop.
3. Fuel injector puller. ~10. Keeps you from pulling on the lines!
4. Valve shim remover and bucket depressor, plus a good micrometer (0-1"). Every VW racer needs to have these. The trick is keeping a well stocked tray of adjustment shims. Once other racers find out you have them, you'll run out quickly! The micrometer makes it easy to measure the old shims and tell if they're dished.
5. Clutch alignment tool. Really cheap but handy!
6. CV Boot retainer clamp pliers. I usually visually check my CV's a couple of times a season and these pliers are needed to squeeze the clamps tight. Also keep an extra supply of these clamps!
As far as pyrometers, go to Ebay and look for one. I found a Snap On pyrometer with multiple probes (tire, air, liquid, surface) for less than ~$70.
Alignment bars? Go down to your local Home Depot or Lowe's and buy a 4' length of 1"x1" aluminum tubing. Cut it in half. Place up against side of tire near bottom of rim, have a helper do the same on the other side and use a tape measure! Works great.
Camber gauge: $40 bubble camber gauge from Racer Parts Wholesale. Cheap, reliable, easy to use.
Other tools I've find handy but not absolutely necessary:
Dial indicator with magnetic base. Makes it easy to check cam lobe wear.
30MM Impact Socket. Helps prevent shattering a regular socket when putting 200 ft-lbs on the front axle nut!
Digital Multimeter. Early Sciroccos have problems with corrosion in the wiring connections. Easy to trace and find with one of these.
Tools I'd like to find and have someday:
CIS Injector tester, for testing spray patterns of injectors. Expensive but cool!
Injector volume tester. Looks like 4 tall thin beakers with rubber plugs at the top. Used to measure fuel output.
