Hi Guys, I have a few quick questions

How are the plus 12-3SCT (or 12-3ST, etc) engines? I read a post saying they are more torquey than the 353, but how do they compared to other brands for top end? Other engines I'm considering are the OS TZ Speed Spec 2 and Sirio Evo 4 (I hear sirio bearings give up quickly). I'm also interested in how the novas compare for longevity, and ease of tuning (and how they hold their tune)

Also what is the best all around pipe for the engine? I've used a 2630 before and really liked it

Thanks
