internals

[LiU]

hi I'm wondering if I should get a turbo or work on my internals... I'm just trying to learn about the 2 and compare

for internals... what can I doport and polish cylinder headscam shaftany more?

can someone give me a detailed description on what they do (the FAQ section didn't explain it that well) and how much they wear down your engine

--PS if I'm just running a naturally aspirated KA there's no need to upgrade fuel pump and injectors right?

yes you woild need to replace to fuel pump and ECU, rework the lower end of the motor for turbo.
