Vehicle Excise Duty - notifying DVLA of engine

The Exige in k series form is Band E (�175) for Car Tax. Has anyone notified the DVLA of a change to a new engine? The Honda is Band F (�190).

Are you required to do so by law?

date of first reg of car?

1/3/2001

Perhaps a silly question but does a s/c influence these bandings?!

I thought it was all based on CO2 emmissions & nothing else Not that I’ve answered your question though
