You have no guarantee, in fact, I'm almost certain the engine on Alibaba is NOT coming from Changan.
so between a used G16 like this at 1500$ and the allibaba at 770$, youd still take the used one form a breaker?
mmm.... thats the question...
That's actually not how I saw the question ...
Anyway - yes - I'd take the one from the breaker, here, I can see what I'm buying before I put my money down, I have a 90 day warranty and can opt for a replacement or a refund - and I don't have to concern myself about quality of the product or whether there will be a problem with replacement parts in the long term.
There’s been a certain psychology here about, say, not buying Chinese timing belts, rotors, brakes, etc., but rather, spending more for factory parts. For example, if you had an interference engine, would you put a Chinese made timing belt in it? Just a thought. I suppose that $770 may be cheap enough so that if it lasts a few years, you might think it was worth it. But I suspect that the used $1500 G16, made by Suzuki, would, at least initially, be a better made engine.
Interesting that you should bring this up - a number of years back I was looking for a timing belt for an interference engine, there was a local supplier who had a Chinese made one for GYD$7000 (about USD$$35), I had the dealer order an OEM belt out of Japan and ended up paying almost GYD$100,000 (USD$500).
It's important that people be aware that there are Chinese products and then there are cheap Chinese products, the Chinese
can build quality products, but they also
do build many products of dubious quality.
A friend of mine runs what I will call a "power products" dealership, motorcycles, outboard motors, gasoline powered water pumps & generators, has a sole distributorship for one of the better known Japanese brands, but faces competition from similar products of lesser quality coming out of China, so my friend flies off to China and buys two containers of Chinese made motorcycles, he ended up selling most of the first container, and cannibalizing the second container for parts to provide "warranty support" on the bikes that were sold. He has since gone back to China and bought more Chinese made motorcycles, from a different manufacturer, but, the second time, focusing more on quality than cost, he's had better luck with the second shipment, but when I walk through the dealership now, I don't see any Chinese made motorcycles, only the Japanese brands.
This is a man, of Chinese ancestry, who speaks the language, visits China regularly, has taken trade delegations to China, who has been "burned" by Chinese products.
When you buy from Alibaba, you have no idea if you're getting a "cheap Chinese clone" or a good quality product, coming out of a licensed partner, such as Changan Automotive, I'm inclined to say the probability on the "cheap Chinese" is quite high.
On the other side of the scale, I'm buying a used Suzuki motor, it is a quality product, possibly worn out, but one for which I can source bearings, rings, etc.
