So is this normal on Sirio engines? I m trying to find bearings the same size but not OEM. Can anyone direct me? As I said I ve gone through 2 sets already, i replaced it every race because juat after 45mins main the bearing just got too much play and sounded very rough. At the moment I m limiting the usage of my Sti for race finals only.

You will find it very very difficult to find bearings other than OEM. The front bearing is the exact same number as the nova front one but they are different sizes. I complained about my EVO3's along time ago as i was having this exact same problem. And now my STI had done the same.

Bearing Size
I have an AB modded Sirio S21 BKEVO3 and really liked up until the point the main bearing went (about 2 gallons). Does anyone know the size of the bearings so I can get some ordered? I have checked Kyosho America and they do not list a size or replacement bearing? Thanks for the help!

Sirio onroad front bearings always leak oil even after 1 start on a brand new bearing I have not realy noiced any bad efects only a small pool of oil after i after run an engine. If people are worried that its realy bad or just dont like the thought change it to a rubber sealed front bearing somthing like a tko front bearing here is there web site. http://tkocompetitiondev.com/shop/index.php?cPath=38_41. they are very good bearings ceramic bearings rb concepts also make a ceramic rear bearing to fit a sirio 21 engine size is ("25.3mm outside dia 14.2mm inside dia and 6mm wide") ive never tryed them but if some one is keen or has tryed one let us know what they last and paform like. Regards Jeremy.

I m having problem with my Sti 3 ports, its actualy a screamer however i do not like the bearings. From new you can feel that the crankshaft is not tight around the bearings, i have gone 2 set of OEM bearings with mine, has anyone got this problem too? Is there any suggestion on which brand r make should I use rather than OEM?

Today i bought a new set of bearings, fortunately the OS TZ's rear bearing is the same size as the Sti however the front one was not the same size so had to buy Sirio's. The OS bearing looks very tight compare to the Sirio. Even when new the Sirio front bearing has got little bit of play. Hopefully this combination will solve the problem. If not I will try the ceramic one that Murnan Mods has on their website.
