What do you guys think the best engine is that will fit a stock maxx? I have been looking at the Sirio .18 and the Picco .21 and both look great. What would be the differences between those 2? Any other reccomended engines? Or other performance mods that will make that big of an impact? Thanks in advance. BTW im at the beach in so i may not be able to reply quickly.

I'd say go with the Sirio .18 cause it is more powerfull but not so powerfull you will need to spend lots pugrading your tranny (fingers crossed lol).

Thanks for the reply. It does it make a significant impact though right? Will it fit the stock chassis and exhaust? One last question, what exhaust system should i get if i stay with the trx (or get the sirio)?

the sirio is great for the maxx and trinity also makes a tuned pipe that works perfectly with it and looks great

which model of the Sirio .18 should I be looking for my T-Maxx?? Is it compatible with the ez-start??? I want to put in a new engine that's a little bit more powerful that won't destroy my gears. No modifications will need to be done to my maxx would it?

As for reinforcing the gears, would i just need a set of CVD's and a steel spur to run the picco?

sirios are very powerful motors out of the box but they lose compression after a gallon or so. the picco is a more reliable and longer lasting engine in my opinion.
