There's a company in poole called magnum engines my mate had his ABF 16v rebuilt buy them lightened and balanced bottom end and flywheel.. I've had them pretty much rebuild the whole of my 1.8t Inc lighten balance bottom end flywheel lightened balanced and new valves guides and multi face valves etc. I can say they've done a sterling job and I highly recommend them if you want to travel... They are very competitively priced too...
