964
 

This is probably the wrong site but I’ve been trying to find some information out about putting a 964 3.8 in a 914. I’d like to know if anybody has run the number 16 AN and the number 12 An oil line up through the passenger side heater, duct and into the front trunk area to the dry, sump tank and cooler , Will the 12 and 16 fit through the heater tube at the same time . thanks for any info . slamming out

Try 914world, it’s been done many times

Nope, two -12 hoses will fit but the -16 is won't. If you need -16, run through the car next to the center tunnel. If it's a street car with a passenger seat, insulate the hose to reduce heat transfer into the passenger compartment.
You might try running the engine to oil tank hose on one side and supply hose on the other. Ben McFarland makes some pretty cool GT oil lines that may help you resolve you dilemma.

Very hard !
