I personally went with the SC46 due to spool characteristics. It's in the process of being built etc at the moment attached to a 2.1 stroker with Enginetuner. Otherwise I'd have gone for the (billet) md321. These were the 3 I narrowed my search to aswell, although there will be other options out there, and I will be interested to see what others recommend.

I'm going to be fitting an MD321T Billet to my 2.1 soon (saving for the ecu now!). I'm hoping for 450bhp but it isn't guaranteed. I think different engines respond differently than each other. Some 2.0L's make low 400's others seem to hit 460's so I'm hoping the 2.1 will be in the upper category!

if you get the sc46 make sure its the old 1 as the new billets dont work to well on the 2.1 stroker and you wont hit your target,if it was a 2ltr then no problem

Seeing as it's going on a 2.1 then, as said, a MDX321T Billet or the SC46 Billet will be perfect. 
Should see around c.475+ - slap bang in the middle of your stated bracket - on V-P only.
And in and around 500 on V-P + 20% meth.!
And the spool-up of those turbs on a 2.1 will be fab! Win-win.
Do it!!!

...Hmmmmm strange comment that one fella
,my mate has just had his 2.1 stroked RB5 mapped by pat up at the scoobyclinic with an SC46 billet turbo fitted and achieved 485/482 with a very power restricting set of standard headers and standard uppipe and a 2.5 exhaust system fitted.Its the 2.0ltr cars where problems can arise with the SC46 as they can choke up at the top and refuse to play ball,the SC46 is a perfect choice for a 2.1 stroked motor in imho.

from having a quick look on sc web site, if i was to sell a as new billet s206 with custom enginetuner down pipe. from looking on scoobynet, they go for around £900-1k. then buy a sc46 with a second hand bell mouth dp, i would need around £700 extra.
so my question is, is it worth saving up the extra £700+? 99% of the time it is day to day road pottering around driving. no track, and the odd 1/4 mile each year.
thanks

I would go with upgrading your existing S206 to billet and you will save money at least,power wise S206 on 20% methanol should make 500bhp and with 500bhp you should be good too on the 1/4 mile drag strip

That's a very sweeping term Bill and certainly doesn't reflect what we the sole seller of that turbo have seen.
The Billet version has a lighter/stronger comp wheel than the earlier version and as such is more reliable, however I have a few out there that have covered in excess of 30,000 miles over a 3 year period of road/track day/hillclimbing and drag racing that are still going strong on the older wheels.
I've had reliability issues with both of the other turbo's you have mentioned, but out of the two the SC46 would be my choice. In my experience of like for like, the Sc46 will spool faster but not make the power the S206B does.

Martyn, if you consider a turbo continuously passing oil and smoking reliable, then I retract my statement. I've had various versions of the s206 turbo, and all have had oil issues to varying degrees. I give the manufacturer credit for taking back the units to inspect without question, but the issue still remains.
At first I thought my engine was at fault, so had it pulled apart and refreshed. The heads were also sent away to be overhauled at a later date when it made no difference. I've tried different breather set ups from standard to modified. In its latest incarnation, I had the turbo converted to the billet version, but this produced even more oil smoke. I get oil collecting on the tailpipe which looks fresh, and certainly does not appear to have gone through combustion.

We have found that certain breather system layouts don't help and have rectified a few showing this issue.
We have also recommended that all future S206/S215B units have a double ring seal as a matter of course and this has resolved any issues associated with it.

The average one makes 450bhp on Vpower and 500+ on a splash of meth.

No need to retract it, you are quite right. The S206/S215 has had issues in the past with oil control, although it is very vehicle specific.
