The manager of a well known team over here who has been racing 1.6 K EU2 stock engines for several years without any problem, is concerned by 8 engine failures since they shifted to EU3 engines. He has been obliged to have them rebuilt with forged pistons. The engines are used in the French 'Challenge Caterham'.
I read on TechTalk that EU3 engines run smaller injectors than EU2 engines. If this fact was confirmed, could it explain the failures, less heat being taken out by fuel evaporation ?
What can be the remedies, other than replacing the pistons @ 1500 €
