[Stez]

What should be diameter of inside passage for oil cooller lines on 1g?

The thing is my stock lines is bad and i want to use another ones... i found very good qualitty hoses: the inside diameter of hose is 8mm and inside diameter of hose fitings are about 5mm

is it to small to use for the oil cooler or ok?

I use a-10 hose on my 1990 oil cooler but, I got mine with a -6. For AN style fittings you could call roadraceengineering or diamondstarmotorsport for the fittings you need.
