I've said it before, and I'll say it again: it's going to be a llllooonnnnggg month. I ordered the turbo and manifold today:
- Turbo: Garrett GT2860RS with TiAL stainless 0.86 A/R turbine housing
- Manifold: Lovefab 'Mini Me AC'
I have been toing and froing between the GT2860RS (a.k.a. the 'Disco Potato') and the GT2871R but, at the last minute, ended up going for the slightly smaller 2860 because of it's reputation for quick and progressive spool up. My initial aim has always been for 300hp atw which, while being toward the top end of the turbo's capabilities, is a number I'm very confident I'll hit. 
The manifold was chosen because it's the only one I have come across that looks like it might fit - there's not really much more to it than that. The guys at Lovefab were very helpful and said they'd do what they could to keep everything as compact as possible.
It will all take about a month to be ordered/fabricated/shipped. Is it February yet?
Update Feb 17, 2010: Why yes it is February! No the manifold hasn't arrived yet :(
Update Apr 28, 2010: Manifold *should* finally be getting shipped tomorrow, but I'll only believe that when I see the tracking number... and maybe not even then - haha!
