A good book to get is "How To Keep Your Volkswagen Alive" by John Muir. This book covers everything you need to know.
There's a few for sale on eBay including this one currently at £5.00 http://cgi.ebay.co.uk/How-to-keep-your- ... dZViewItem
The VW T3 engine is more expensive to tune than the T1 (Beetle engine) and there's also less uprated parts available for the T3 engine.
You can remove your T3 engine and fit a T1 in it's place with only a few hours work so it might be an option to buy complete T1 engine that has had some tuning already done if you feel the current engine is weak.
There's quite a few club members who use the standard 1600 T3 engine without any complaints. The engine is only 50 BHP but with the covin being a light car, power to weight goes up and BHP per tonne will be more like 80 BHP so it should drive ok and cruise at 70 to 80 mph without problem.
The most important thing to remember on these engines is REGULAR OIL CHANGES and OIL LEVEL, unlike modern cars low oil level on these can destroy an engine very quickly so check your oil often and only use MINERAL OIL, either the cheap stuff £2.99 Wilkinsons or Halfords 15/40 Enhanced Mineral Oil which is what I've always used.
Club member Andy Devlin or Chris Mills can offer you some advice on tuning the T3 engine as they've both built their own T3 engines...

Might be worth checking out this website for ideas on tuning and what performance to expect JMR Performance Figures
You'll be surprised and what power output they can deliver if your prepared to spend LOTS of cash
