Sirion 1.3 engines

1

Wondering if the later 2005 1.3 sirion engines are a direct swap for a 2000 gtvi engine. Do they also share same gearbox?

The engine should fit right in but the gearbox is a bit different, they run a hydraulic clutch whereas the earlier ones have a cable. as far as I know the later 1.3 doesn’t have as much power, they are a k3-ve and the earlier ones are a k3-ve2 which has higher compression. The later k3 does have a better cylinder head though, sharing the same head as the 3sz-ve (1.5l)
Hope this helps

front cover + mount is different also, you can swap on your older one
