Fuel jets? Jets are for carbs, do you mean bigger injectors? Bigger injectors wouldn't be needed unless you were going for a decent turbo setup.

i think just camming and a decent remap should sort things out

You wouldnt need to touch the injectors if you were just putting a cam in it. I aint clued up on prices or power outputs for cams etc on VTR's mate as these cars are new to me so i cant comment on that.

If you change the injectors for anything other than direct replacements - you'll need to adjust the ECU to suit. Although i'd imagine it'll be able to adjust for a very slight change in injector sizing - anything much bigger will result in overfuelling as the injectors will still stay open for the same amount of time, but because they can flow more in a set time period, more fuel in the engine.

Good standard injectors will be fine up until at least 160bhp on a VTS. Not sure about a VTR but i'd imagine 130/140.
