Questions regarding the R6 throttle bodies

So I have this old R6 but I wanna do a throttle body swap with a new one from a 2006 R6. It' kinda confusing to me right now and the new ones are a little bigger than my stock. I'd like if I also add a Graves ZZZ Throttle Slide Stop on the throttle body before I replace. How can I go about this? I'm not really sure if I need the fuel pressure booster with the kit because I'm not using 03-04 throttle bodies now. I'm really confused and stuck so please any help will do.

no, no. since you got the 06 you don't need the booster anymore. that's one thing yeah. but do double check the TPS! just might need some adjustment when you switch your throttle body.

Quite tricky if you ask me. but do you think you can get this checked and tuned after the swap? It's complex mod so please be careful
 
Swapping can definitely boost performance but yeah, as mentioned, it can be tricky. The 2006 bodies are bigger so you'll need to consider the ratio of the air and fuel. I agree with the above to get it tuned after the swap to prevent damage.

That's a nice upgrade! The throttle bodies from 2006 are larger, so it makes sense to add the Graves ZZZ Slide Stop for improved response. Since you are not using the 2003–2004 throttle bodies, the fuel pressure booster isn't necessary, but it can be helpful to manage the extra airflow. Just be sure to adjust your ECU settings or use a fuel controller once you've made the changes.
