About sirio pipe, what version I have to buy for a Mugen MTX3, standard one or serpent one? Which spacer come with the kit, long one or short one?
only one question more, what can I do the break in procedure? Same as abc engines?
well, there's a lot of questions 
. Gracias Alfonso 
Hola Toni
You can use Novarossi C7TGF.
I have a Mugen MTX3 Prospec, and I use the standard type.
I'm not sure which one came on the pipe, but they are so cheap, that you might wan't to get both, just in case.
For break-in procedure i've answered your private message at Coches RC forum, I'm Papo over there.
BTW, check my previous posts here about carburation of AAC engines.
