The JLR may be price worthy for performance...but will it have the bottom end I'm looking for...assuming I couple it with the yellow clutch shoe, LW shoes, and soon MSR hard spring?

Grey shoe working best with what? I have to say using the yellow shoe compared to the grey was a lot better. I'll keep thinking about what motor I'll go with though as I have lots of options.

5 turns from closed on the hsn and 2 1/2 on the lsn should get you in the ball park... From there, you should be able to fine tune your motor... :cool:

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.

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.

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.

Get the 2611 pipe and don't rush the break-in, take your time to do it.

On this engine is vital to know how likes to be carbed. He likes (no... needs) to have a nice LSN adjustment (if you carb it like a Nova will be a dog). Their 'good' LSN adjustment under a Nova carb adjustment is 'too lean' (for a Nova).

It holds nice. Forget your temp gun and adjust it for performance, meanwhile you have a trail of smoke, your monkey will be fine.

What would you suggest as a good starting point for LSN?

Sorry I use it with 16% nitro, so the LSN and HSN adjustments for someone using 25 or 30% are plain wrong.
