A couple of more pictures. Since the diff is toast and the car is going to be sitting a bit pending a new diff, I figured i'd tear it apart again and start working on the downpipe. Since i'm doing a 3" bellmouth, i'm waiting on my flange and oval to 3" transition from ATP. I'll have a v-band on the outlet for ease of removal in the future.
Here is how it sits right now. I dont have the hardware to attach the turbo to the manifold yet. Not sure what i'm doing since there isnt' enough room to through-bolt it. Guess i'll just do 10mm studs like on the old BEGi manifold. What bit should I drill the holes out with for that?
Keep in mind its also not clocked yet. I still haven't figure out what i'm doing with the mixing manifold and lower radiator hose, either. Was contemplating doing what neogenesis did with his setup.

I sent you thse 3/8-24 12 point arp nuts and some washers. Oh well.
I have used those ATP 3" oval to round transitions before...they do not arrive as described. Neither side will be "flat". But still easier than hammering a pipe oval over that sort a distance.

Oh, well I can just as easily tap it for a 3/8-24 stud setup. I still wish I could use through bolts. Unless I ovaled the holes out to be able to tilt the bolts to get them through it just wont work :( Not enough clearance between the collector and the flange.

I think the turbine flange needs resurfacing as well. At this point I'm just trying to get it together and get the downpipe done and running again.

I realise the Greddy manifold always had problems and these were solved by stress cuts. But why does this manifold have cuts (for the Greddy reason?) around the bolt holes? Surely it was the tubing expansion that you want to correct so strong bolt holes help?
I notice TurboTim doing this too can someone please give me clue :(
BTW I think you've done a bang up job there well done.

My round to oval transition and flange came in today along with tim's fancy nuts.
Downpipe build starts tomorrow morning.

I actually dont like the way its fitting with this particular v band flange. At first I thought it'd make more sense to use the heavier duty flange on the turbine exit, but now i'm thinking i'm going to change it to a lower profile flange I got from Abe (artech). The inner diameter on the smaller diameter one will allow me to slip the transition inside (giggity) it and leave me about an inch or more space for the first bend of the downpipe.
I have pics but Photobucket is down at the moment, will post them up as soon as I can.

Pics of the assembly tacked together. The flange also doesn't fit the turbine housing unless I bore out one of the holes larger. I noticed this same thing was done on the BEGI downpipe flange so I dont feel horrible about it.

I know. I've got an affinity for cheap beer and now that I cant afford good stuff i'm forced to drink cheap stuff exclusively. 3 nights ago you would have seen a Mickey's grenade sitting there =P
Btw i'm not jobless anymore. Welcome to Costco, I love you.
And what about 2 nuts?
