Hello,
A good place for you to begin is to start using punctuation in your posts; all your questions ran together and it is very difficult to read. I would suggest you look at Pro-Motive's site where they have a FAQ and section on which models of R1 engines you should be looking for.

Cheers

As far as I know all engines up to the 2002/2003 model use carbs. Carbs are ok, but you will need to re-jet for a car application of the engine.

From 2002 onwards all R1s are injection, although for the 2007 model they have gone back to 4 valves per cylinder, instead of the usual 5 valves per cylinder up to 2007.

One disadvantage of the R1s is that they use an EXUP valve, which closes/opens the exhaust to generate some more back pressure at low revs. I'm sure which models have this, but the 2002/2003 model has it.

I'm hoping to keep exup in my set-up, but have no idea where to mount it.

I've gone for the west-garages kit and the 2002/2003 model. The 2004> models have 180-bhp, the 2002/2003 and before have around 150bhp.

So the best model to go for? The 2004-2006 model, if you have the cash.

I'm not sure what fits into the Pro-motive frame though.

Anyways, you should really go for the 2009 R1 engine

FYI from the Pro-Motive site:-
The forth generation was launched in 2004 (5VY) this is a totally new engine that is larger than the previous models, so unfortunately will not fit in our kits. This isn't a problem though as there are hundreds of low mileage 5PW, 5JJ and 4XV engines around. Power is now up to 172bhp.

The latest engine launched in 2007 (4C8) is all new and changes from the 20 valve Genesis unit to a 16 valve setup. The same applies to this engine as the 5VY and makes it unsuitable for our kit. Power is now 180bhp, throttle is fly by wire, and it's now fitted with YCC-I (Yamaha Chip Control Intake) which controls the throttle body trumpets causing them to squeeze up when revs rise above 10,400rpm
