Just got my first 'racing engine' and need some advice

I have just bought the Sirio XXX and for unknown reasons it came without it's manual
My question is about breaking it in
What plug should i use for breaking it in? also do i need to use Sirio plugs only?

Thank you

use s6 for break in and s7 for race tune. picco plug fits too.

r3nos you have pm

Chadster...... Just picked up a couple of XXX`s.

I hope I can run 1 or both in before Qld.

Look out........

cool, the more run in the better, mine was bad on fuel while it was still tight , but now it makes 5.20+

oops

Just picked up a new XXX V. Breakin time. <---Patiently waiting to pull the trigger.

Guys thinking of getting a Sirio engine from running Picco based engines, I read somewhere I can use Picco plugs on the XXX V is that correct ?

What pipe would you recommend for that engine, is the engine easy to tune and give good fuel mileage.

Also is the engine suited for tight tracks with few straight ?

thanks all

i would recomend using sirio no 7 , they work the best of any brand of plug,
and they are freaking awsome on any track tight or open , you will be happy

Does anyone have info on this engine. I would like some input on gearing , Plugs , and fuel. I'm putting it in the Inferno GT. It came with the big boy off-road pipe, but if you know of a good pipe, I would like to hear from you. I do have a JP-2 I could use , but I'll buy what I need.

Hey guys,

I ran the sirio clutch for the first time competitively over the weekend. Managed to qualify 3rd and finish 2nd at the Queensland champs.

I was just wondering if people can share there clutch settings for this clutch.

I didnt have much time to muck around with the clutch and a destroyed bearing in the clutch during quali cost me a couple of heats.

In fairly high traction I ended up running .7 on the nut with a .5 gap.

can someone provide me with some links on where i can get the sirio clutch? thank you

anyone know the part numbers and sizes for the front and rear bearing of .12 evo4 STI?

Hi, I'm finding the flywheel of SIRIO clutch too, thanks anyway.

Hi from Australia,

Here is my clutch setting: ended up .6, .5 gap. Traction is middle.
