How do you compare a .18 and a .23 ? They are in different class. By the way, if you getting a .23 check out RB TM232 as well. You can get that for around 250 shipped, come with everything (header, pipe, engine mount, and of course the mill)

Edit: RB TM323 and not TM232
 
I have a Sirio .23 in my t-maxx . The engine is extremly fast and has a lot of power, but it is impossible to find parts for.
 
I have a Sirio .23 in my generation 1 Maxx and my neighbor has the RB 323 in his Revo. Our gearing is a little different, as his is geared for more top end, but still... I can pull on him when we're street racing as long as I'm easy on the throttle on take off. There's no way I can keep the thing from not flipping on it's lid if I nail the throttle on take off. At all.

Still running the thing very rich (only had it about 3 weeks, not to mention it's blistering hot here at the moment).

Agreed that Sirio replacement parts are a little harder to find, but the .23 is certainly easier to find parts for than the Sirio .18 was (which is what I replaced the .23 with).

Personally, I don't think anyone makes a finer mill. Just comes down to if you want to pay the premium price for performance.

The Sirio .23 also comes with the header and engine mount specific to the "model" you're putting it in (there's an RE-23 and a TX-23 for Revo and TMaxx accordingly).

I'll throw my :2cents: on the OS...easy to tune and OS makes a damn good mill for those .18s......I know the race Revos running the .18s at my track can mess w/ the buggies for sure...what is "ALL aluminum" include? if your bashing I hope you didn't use aluminum A-arms......and do you still want to use the EZ start? if you set your up for bump box do the Big block conversion from Traxxas and just throw in any .21 and that thing will FLY......even an RG w/ a real tall gear can move that little bastard faster than a tick on a wallaby's ass...LOL...I love that saying....
 
well i did use aluminum a-arms and they take more of a beating then my plastic ones
 
ya...carefull with the alum arms...they take more of a beating but give u a weak point elsewhere....like rip the hingepins out and the slots they go in!
 
Try your best to avoid hitting anything like curbs.... those a-arms won't last long. They make take more of a beating on soft impacts, but they'll certainly bend the first time you hit something hard.

Always a good idea to put something like plastic or nylon at the most prone points of the truck that are going to take impact pressures. Same neighbor I was talking about above had alum* a-arms on his revo, and bent one of them the same day he installed them. Back to the stock a-arms within 30 minutes because one of them was bent beyond being able to use it.
 
i dont drive my revo on the street.only dirt because of those reasons
