Many on this tread we have a STi,.... take your time to break-in and he will reward you with a very quick engine, with more power than the stock one... you will like it.

Many of us we invested up to 5 or 6 litres fuel making a break-in... take your time and use the Evo3 pipe.

Hey austin....glad to see you got the motor......as you saw yesterday at the race the motor has good power through all powerbands....and remember that motor is not fully in yet

robert my man was going on? yea the motor was fast of course. plus your car is always hooked up to! nice race last night. im going to wait till i get the sirio pipe before i break it in. well be back soon. see ya then

good idea waiting for the pipe.......

hi,

did anybody know what is the horsepower for this sirio evo3 sti? i has bought a new one yesterday. during checking the package, a bit dissapointed about the documentation provided. anyway, feel excited to break-in and proud to own one.

thanks.

Manufacturer hp ratings are always a bit biased. This is also why Sirio does not have hp ratings.

You won't be disappointed with the power this motor will generate. My EVO3 STI the hardest ripping engine in my bag right now in comparison to my other motors, that includes modded JP, Rex, and OS.

Dom

I agree with Dom, Hp ratings are very overrated....Just make sure you take your time and break-it in properly...preferrably on a break-in bench..and it will scream..

oh, thanks. currently i'm using a LL5 but i found this motor difficult to get a good tuning plus it is very easy to overheat compare to OS. that's very disturbing.

will this motor difficult to tune? any advise? because i'm the only one who own a sirio evo3 sti in my area. during break-in period, what's the important things i need to take note?

thanks guys.

This motor isn't difficult to tune, but do small increments at a time.

Hi help can anyone tell me where i can get any sirio evo2 or evo3 rods as i am in desperate need.
Thanks Brett

try kelletts hobbies as they are the sirio importer for australia and should be able to help as the have plenty of stock

how many tanks do you perfer on the beak-in bench b4 i put the STI in my car?

Break-in bench? Better to not use one (never been a fan of those d*mn artifacts) and install it on your car and go thru the tanks running it.

Austin not sure if you got my PM regarding the break-in...Josh Cyrul has a nice article on his website regarding break-in www.cefx.net... with all due respect to Corse alot of people have different ways of breaking motors in...I have my own method if you like to know you can pm Austin
