On the above engine in my 331 the hose between the intercooler and the turbine housing is about 120-140mm long, clear with a ‘reinforcing’ external sleeve.
I assume it is the original and I am wondering whether it should be replaced by a silicon hose ?? Has anyone replaced this hose and which source ??
