Bart,
You should be able to do it yourself. I don't think there are any special tools required. Of course I've never done it on the VX so I could be talking out my arse.
If you do it yourself, one word of advice. When all is put back together, turn the engine by hand first before you hit the starter. When I replaced the timing belt on an old Eclipse for the second time, I figured I had the process down & almost talked myself out of turning the engine by hand. Somehow I had messed up & the timing was waaaay off. If I had hit the starter, the engine would have siezed.
