Not that I know of.

I think a small amount of confusion is coming through this thread. I'm not saying that if you do not use a reroute, your cooling system will overheat. What I am saying is that a reroute will improve the cooling to the rear cylinders (particularly #4) and make cooling more even across all 4 cylinders, thus improving efficiency. It should be of benefit to those who will tune (or plan to tune) their engines, or work them especially hard. If you look on the threads I've linked to, you'll see that the majority of people who have fitted a reroute have tuned engines.

I took the attitude that it was better to do something like this during the build and err on the side of caution (although I'm considering FI further down the line) than to build it all up and then find it needed tearing back down to make modifications because something was marginal. You might call it the belt and braces approach.

Good point.

The chap running the group buy is almost ready to put the order in, so if anyone is interested, they don't have a lot of time to get it sorted.
