there are a couple of tuning places in aussie that will bolt on an exhaust, intake and remap the standard ecu in an XR6T and you have 280-300kw for next to nothing.
At the end of the day turbos will always be easier to get more money from but, and this is just my opinion, tuned NA will always be more rewarding/fun.
anyway to the OP
Set of really expensive toda headers (dont bother with cheap ones the stock will be better)
2.5 inch straight as possible exhaust.
cold air intake
lighter flywheel ( I did this to mine and it made a BIG difference)
link ecu
should have you around 110-115kw atw which in a BZG will be really fun.
If you want more then it would be
forged/silvertop rods
cams
Maybe light port and polish.
Probably takes you to 120Kw atw-ish
After that then its just more and more insane cams and perfecting the flow of air in and out of your engine.
These figures are just best guess though as 4ages tend to vary lots in what they produce
