You can also port your oil pump hole(in the block), but that gets a little more involved
nearly every thing that is a casting can be ported. The inside of the block can be ground and polished to help with windage and oil return to the oil pan. This also helps with strength. list goes on. Most parts ported have to do with air flow, the direct path to power and high VE in the engine. But other things like porting the fluid path is important, oil and water flow. Most commen so far on a TDWhat other parts of the car can be ported? ok, oil pump hole, water pump, Intake manifold, exhaust manifold, head ports, i think also de SV? anything else?
I've saw on guy on here that was selling a "ported" t2 intercooler...:lmao:
