Most of the guys in our area run the Sirio buggy motors anywhere from 230 to 275. Don't worry about 260, it's just getting into the right temp range - so to speak.

There are some in australia.
They are in my tool box, not for sale though ah well

Kellets in Sydney had some a few weeks ago, give them a try, as with Kickass i have some in my pit bag also

Silly small question.

Does the Sirio Evo4 come with its own collet as none of the photos I have seen online show one? Just need to know if I need to order one with it...

which sirio engine do you guys suggest for my v1rrr. Im really confused on which one to get, also how many gallons of fuel on average are most getting before a rebuild, and where can I even buy these engines

Kyoshoamerica & MurnanModified carry Sirio engines and parts.

hey guys,currently i am on evo3 and evo3 sti,but my sti shotdead when the bearing and piston liner damaged,so now focus on my evo3,good running race engine too but little lack from sti ofcoz,soon to run on evo4 with power clutch for NT1,cant wait to wack this january national championship.

anybody kind to share about the power clutch setting for NT1?any difference from the stock clutch?

Theres an evo4?
Im an OS man but the Evo3 STi KIKS A$$!

You're not just whistling Dixi Al

Hello, I have just tried Sirio Evo4 on Melzo (Italy) track, where Sirio Official Team tests and develops engine and where I run.
I have used in the past Sirio Evo3 and Evo3 Sti, but according to me Evo4 is the best, it's really fast!! Now there is a different steel bearing instead of Evo3, and if you want you can also use a ceramic bearing made by Sirio.
About pipe, Sirio sells now a new edition of Efra2611, you can see in picture the difference, it's stronger.
About glow plug, there isn't in the box with Evo4, but use n7 for best performance!
If you need other informations, also about purchase, please be free to contact me, no problem!

still cant find any where to buy the evo4 engine and pipe and someone post a link

hello, sirio evo4 is sold in some italian shop, I don't know outside Italy. If you need info or links please contact me.
bye!
