More horsepower

Hi all I'm looking at the idea of getting a bit more power out of my discovery 300tdi. I'm looking at ideas. I'm toying with the idea of doing a couple of pump mods ie boost pin, boost ring ect. Has anyone had any issues doing this. What other mods can I do that won't brake the bank. I'm not looking for big bhp just a bit more

The 2 you've listed are very common and literally 5 min jobs.

Make the 300tdi a tad faster.

I can think of hybrid turbo bigger FMIC.

The max you can go on the 300 is 170hp IIRC on stock internals.

Bigger intercooler
