As the search is still out of order, I'd like to ask you guys, what you think is best. In the manual, it says that the water temperature should be at least 70 degrees Celsius. The best operating temperature for track driving should be between 70 and 80 degrees.
On the Caterham parts website, I can find an 88 degrees thermostat for the Rover k-series. I also see an 74 degrees thermostat. But it's for the R500.
I've also read that there are 'remote' thermostats. Would these really be better? Does anyone from here use these?
As the engine get's rebuild now, I'd better do right first time.

Depends what the car is used for. For a track car I would remove the middle of the 'stat.

A massive can of worms! Try searching the blatchat.com TechTalk section for thermostat and you can read pages of stuff about this.

I don't have a stat in my car - it takes a bit longer to warm up and the temp drops a bit when on the motorway, but I've had no issues with it like that.

after a HGF in the first 1100 miles of ownership on our VHPD I went the route a lot of folks have with great results. Go to a Rover parts dealer and get the Diesel 1.6l 78-82C thermostat. Don't worry about word Diesel, it's just the right part. Take home, drill small 2mm hole in the solid part of the flange to all a bleed.

Then proceed to replace it, bleed car, etc.

Works a treat -- there is a tiny downside that your heater is not has hot, but your engine is a LOT cooler. Cool with a K is a good thing.

google PRRT or search on blatchat. You'll need to do a small bit of re plumbing, but at least the t/stat will then be on the correct side of the water flow in terms of doing its job correctly.

Otherwise try and 82 degree stat. As stated, drilling a SMALL hole in the outer flange will assist with bleeding.

PS it's worth testing the stat in a pan of water to make sure it opens. There have been some instances of new stats sticking, which requires dismantling everything again.

PPS be very careful with the O ring seals in the stat housing when taking everything apart - they're fairly delicate and easy to damage!
