Thread: New Nissan 3 cylinder 400hp 88lb engine :0

But why a belt? Was the weight such a concern? I like chains

Both designs have benefits. The belt allows for shorter block, less oiling requirements, easier routing, less components, quieter operation, easier/faster to replace, most likely cheaper also....just to name a few. Who knows what they have going on in that head. I would hope at the least there is some sort of variable timing & lift system in there but with only one cam driven and not much room that looks like it would be very tricky. If I were to guess the cams are connected with a gear at that bulge on the valve cover.

VW doesn't seem to have any qualms about doing this very thing.
Stupid German water pumps!

Wow, that's impressive. Nissan has outdone themselves again.

thats really cool. but how will this trickle down to the sentra or a potential s-chassis
