As above, Nissan Micra battery is the correct size for a Glanza. Dunno if you have Bulls Eye branches in your parts but that where mine was from £30 ish too.
track view http://www.youtube.com/watch?v=lFU3xSAwWMQ and a nice pic There is also a pretty nice vid of the JAM glanza at tsukuba from the same user as the first vid.
There are different types of ct12 not all are direct fit. They are worse than stock ct9s so will be nothing like hybrid ct9s. Take a look on tgtt they have been tested a bit on there.
Blitz K1s use CT12 exhaust housings and shafts. Im almost certain ive read tongs use ct12 parts. ct12 exhaust housings tend not to be cracked like ct9s as they are from diesel models making them ideal for hybrids. Im sure the end result from a ct9 or ct12 hybrid would be no different its pretty much the same thing.
Looks like any other starlet with import size plates to me. Id be more worried about whatever camera you used to take those pics? There some shit quality pics.
Welcome to the club! Mine has the exact same writing on it saying k1200v and it looks the same handwriting, how strange. Im now going to go check this hasn't been stolen out of my car!
it will be the battery in the origonal fob thats poo. dont forget it will be at least 11 years old now. a new fob will work better but its only infra red and its never going to work from very far.
Do it, it looks good and cheap mod for the n/a. In japan they use square plates so its just how they roll anyway and it dont look odd without glanza lights. example: also make sure you get 13 x 6.5 which is the correct size for jap imports!
