Cheap cam gears from China


Bender

Recommended Posts

Got question about cam pulleys from China. I know they cheap and you cant expect much from there but i need them for standard NA (so nothing over 225BHP[emoji2369]) as i got clear cam cover and next month i will be doing cambelt (blue gates rpm) and it will be look nice with new cam pulleys so just wonder if anybody use them or got some usefull info? Or its better to Save so more for proper one or leave it standard one?

China uses materials that are not pure. You may consider China to have less durable or strong material. Not in all cases, but in more cases than many industries we use day to day. I've machined aluminium for sudden hard chunks to arise their head randomly peppered throughout a billet block. Most perceptions are that China create 'weak' parts.

 

However the reality is much worst. There is traditionally an inconsistency with the materials they make. The parts are not weak. Which is worst: a chocolate teapot or a metal teapot with a bomb inside - trust me China dont make chocolate teapots. Maybe glass is a better description.

 

The raw materials are typically not an issue when exported directly.

 

Aerospace industry will not even use a China based company or product for their components (maybe tooling or fixtures).

 

When you consider an NA not big power. You quantify China products as weak. But when you take into full consideration you may have a material that could fail at an unknown value due to lack of repeatable processes and globally known material anomalies, the rule of thumb that 'it's only an NA' goes out the window.

 

Consider the product potential you fail at ANY power level. If you're okay with that. Then it's not a problem.

 

I would challenge ANY top performance product against Chinas best capability to product performance parts. NAt kits and turbos are a great example of success. However, statistically you are world apart from reliability. It's a gamble.

 

To summarise. I would always consider China parts inconsistent rather than incapable.

Thats what im worring about but since im not going for a big power there is a "maybe"

Power has nothing to do with the stress a cam gear will see.

 

Personally I would paint or powder coat the factory ones. Unless you plan on spending top money on a known quantity

Don‘t want to highjack this thread, however thought it could be of some help for the thread starter potentially.

I have a brand new set of quality cam gears sitting here and due to change of plans eventually for sale.

 

Those are Brian Crower cam gears that are used by a lot of 2JZs in professional motorsports (Formula Drift etc.)

 

If you are interested just drop me a PM.
