20b engine size and engine number

[leeroy_25]

Calling on all you 20b owners! I need to notify DVLA of my 20b engine swap. Can anyone tell me what Cc their 20b is listed as in their logbook? Also does anyone know where I will find the engine number?

Thanks
Lee

I had a similiar prob with Westy...but managed to get log book changed to 1308cc (rx8 powered).  I used service book from rx8 donor that clearly stated 1308cc and an mot garage wrote me a statement saying vehicle inspected and mazda rx8 1308cc engine installed...i then included a statement that concluded that vosa classed the rx8 rotary engine as 2600cc but mazda as shown by service book is classed as 1308cc....it took a few attempts as typical dvlc incompetence by i got there in the end.
My mate runs a mot garage so knocked up what i needed on headed paper but if you know a garage owner or similiar can you ask them to help you?
