plasma 327

I have a quandry fellas, I am not sure which engines to choose.
I have 3 Revos, 3.3 no.1 is Sirio .23 equipped and nuts!!! to drive!
Revo No.2 is a 2.5 with modded 3.3 which is powerful in it own right.
Revo No.3 is 3.3 bought new and wan to mod!! I want to get an
RB TM523 kit for the revo with no engine. Do you think It would perform
as well as the Sirio or better if not what do you suggest? Oh by the way
MONEY is no object. NOW I also have a 3.3 Maxx and I was going to put the
Picco .26MAXX in it. WHat is everybodys opinions.
Here are pics of my trucks in question.
Thanks!
