what size fittings/lines/restrictors are you using for custom oil feed lines for a k24 turbo.
I can easily put together a 4an hose but I am having trouble finding 12x1.5-3an adapters. So would 4an work
I think I used M12x1.5 to 1/4"npt and then 1/4" to 3an
I can get whatever you need but it is pricey, I think around 6 to 8 dollars/adapter.
