I'm thinking about installing improved thermostat to my coupe. It should open earlier then stock to lower working temp.

I know there's such unit for 16VT engine (Lancia Delta), did anybody see such for 20VT.

Or I'll have to build it myself )))

Thanks!

Why ? The current operating temperatures are there for optimum running. Lower those temperatures and you'll get worse economy and also run the risk of increased engine parts wear.

Agreed, should be better to make room for more air to the radiator or/and uprated radiator (Pace alu?). IF you have temp issues..?

living in Greece (ie much warmer than you lot up in the UK or Russia!) noone (even the 500bhp guys) complain about running temps.

I use custom button to turn on the radiator fans to cool down to 70degrees when needed.
Thinking about cutting in two NACA ducts in the bonnet. like on F40 or ford gt40. they should bring more cool air without ruining the design
