Sirio 23 vs Picco 21 drop in

[jon2]

Ok fellas I am really wanting to get a new mill for the Tmaxx and want to get one of these two. I don't want to get a conversion for it so these are my choices.

What are the Pros and Cons? What are the neccessities of having either? I know that a tuned pipe is in order so I am getting an 063 pipe or maybe even a JP-1 still wondering.

I would like to get some peoples experience with them. What problems are known. What are the performances of each?

Thanks fellas for the help!

All I can tell ya is Sirios tune 10 times easier than Piccos.And the .23 was awesome when RCNitro dynoed it.They said their wasn't an engine they tested that was as strong as the .23.

Glad to hear some good news of one.

I haven't owned a big block Sirio but I did have a Sirio 5 port .12 and it was very easy to tune.It was the fastest engine I have ever seen in a touring car..I was beating all others and the temps were around 200 deg.

Sirio .23 is better but look at the price

another vote for sirio here. i run thier .15 outlaw 5 port in my super nitro. very simple to tune. super fast, and also held a steady 200*. i tried to get it hotter and it lean bogged first. amazing engines.

If you have the $, I'd go Sirio. I've had a few (not the .23) and every one of them have been great. I've had a few Picco's, and they are great too, but a little touchier to tune.

I got the Sirio 23 and love it

I'd go with the Sirio .23 seems like the better choice I've had no prob with my .21 Sirio, wicked fast and easy to tune.
