Timing chain instead of a belt. Would it be possible?

9300 RPM.
Never needs replacement.
Very good throttle response.
Runs a much more sophisticated valve train.
Only downside: it's louder.
Now, as to swapping-- that's a different story. If you must have a timing chain it would be easiest to get a different car. I would bet that it would also be easier to swap in an engine (such as an F20C) then to try to cobble together a timing chain onto an engine built for a belt.

Be my guest.

It's also an engine designed for a timing chain, and the chain itself probably is designed to be light.

I was only trying to make the point that timing chains are superior in most regards to belts, except for NVH. I haven't the foggiest notion of what your point was.

I dont think A chain would be that bad at all, Alot of the newToyota/lexus and others are all going chain. Its really not as bad as you al think it is. It would not suck that much power down to be that noticable.
Here is a idea, WHy not just not run a belt or a chain, Get a electric waterpump and some electric sylinoids to run the valves ;-) I know crazy, But it is the new technology that will soon be here
