Not always an old motor that uses a timing chain. The K-series run a timing chain.

A chain has a much longer life than a belt, and in theory will provide more accurate cam timing since it doesn't stretch at all. Downside is expense and noise. Sometimes tricky to install.

Chains do stretch. I would say worst than belts. They don't phisicaly stretch. The gear wears down and the rollers in the chain get smaller. This can throw timing way out.

It usually only takes 300,000 miles for that to happen...

doesnt the f20 and f22 (s2k engines) use a timing chain? well, since it uses a timing chain, do they have special cam gears to adjust timing, or is there something else that they use?

Yup, S2000 use a timing chain and the gears that go along with them. I don't beleive there is any adjustment on them.

so there arent any cam gears for them? so the only way to change timing would be a new ecu or EMS right?

Timing chains are said to withstand more horsepower and high rpms...
