    Chain or belt driven?

    I don't know if this info is already out there, but I don't recall seeing anything about it. So if someone knows whether the valve train is chain or belt driven I would like to know.

    Hopefully the new engine is chain driven, because there's just a slightly more mechanical feel to one. Not to mention the smoothness, quietness, maintenance, and reliability advantages of it.

    All new Toyota's are chain driven although I'm not sure if that made it's way into the BRZ

    I have a feeling it will come with a belt, but I always like when the engines are chain driven. I'll try to digg up some info on this

    90% sure it's chain driven, the new Imprezas that get the FB20 are all chain driven so pretty confident that the FA20 is also chain driven I see no point into why they would change it... cause basically the FA20 is just the FB20 with direction injection...

    This. Though not sure about the relationship between the FB20 and FA20, but Subaru is moving towards chain drive timing. I guess they're more efficient than belt-drives, even though they're heavier.

    Can't seem to locate the articles, but I have seen it stated that it's chain driven in a couple that I read. I won't buy a vehicle unless it's chain driven. Seen too many horror stories of a timing belt failing prematurely.

    I found this photo long ago and it clearly shows chain driven cams.

    Thanks for the info guys, but I found out it was indeed chain driven awhile ago. Should have updated the thread.

    All I know is that the Evo X's are chain driven and many are having up to 10mm stretch within 30k. Which leads to it derailing and making trouble or throwing codes and having to be replaced. Its quite dissapoiting as chains were supposed to last the lenght of the engine.
