As per my post - operations with their own supervision can achieve good quality anywhere - I've seen some fine engineering come out of the fareast but I've also seen some terrible junk.
The chinese style of copying is very much ^C , ^V, copy and paste engineering. Take for example the distributors that has given rise to part of this discussion - there is no reason that (as an example) that the BA thread patterns that may have been used in the past should be used now - but I bet they are. The same thing, if you're engineering an electronic distributor then why on earth would you use bob weights and springs? You wouldn't, you'd use the SPi distributor with a pickup - smaller cheaper, and the electronics could be programmed in 2 minutes with a matching advance curve, even the vacuum advance could be handled electronically.
It's not going to happen though - and I have my doubts that if someone checked centrifugal and vacuum advance that they would be that close to OEM spec, or maybe yes, maybe no....
I've seen entire copied multi million dollar projects, complete replicas of western products, down to redundant holes and odd screw pitches that were religiously copied. Yes, they were cheap and perfect copies, apart from the material specs, which in some cases were a joke.
I've also dealt with a couple smaller suppliers for a couple of projects, and they told me that they wouldn't supply bearings or belts because they plain and simply couldn't buy anything of any quality - yes the box said "SKF" or "Fenner", but the closest thing to reality was the box itself.
Agreed, economy from scale of production and lower labour costs can bring down prices, but there is a bottom line for everything , get below that and your going to be buying junk - take the compression gauges on ebay for a tenner, including VAT and post. Just how much are the being made for wherever they come from? And can you actually buy the raw materials for the gauge, hoses, adapters and box for that?
Everyone has to make their own choices, it seems the market is already flooded, and any comment is often received as sour grapes or racism.
I know for a fact that I'd like to see good old clunky English engineering in my old mini as far as possible, not imported stuff, not unless what I fit is proven to be substantially better than UK engineering.
