You mean every single part like piping and everything?
For my simple bottom mount.. all the things i can think of that i used to make this happen;

Turbo, wastegate and other supportive mods
-JB4 boost controller with MHD backend (2step/NLS, HMD supportive cables, bluetooth connect and phone or tablet to log)
-JB4 connect MAC solenoid
-3.5bar tmap sensor + harness
-Precision 6466 gen2 ball bearing divided T4 with 1.0A/R exhaust housing and 3-5/8" discharge
-Precision 46mm wastegate (springs and flanges are included)
-4" turbo guard
-VRSF chargepipe with Tial BOV
-CCC Single mass flywheel
-550i clutch (not sure if this will do but i've seen it on many hybrid N54 with no issues)
-Wagner EVO2 intercooler
-Vader Solutions PCV delete + breather system
-Titanium turbo blanket
-Oil pan gasket while you're there
-Valve cover gasket while you're there

Fittings for drain, feed, vacuum and other small parts
-2 x coolant plugs from ACF
-Single turbo oil feed adapter from ACF + 1/8NPT to 4AN adapter fitting
-2 x exhaust gaskets for downpipe to exhaust
-T4 divided gasket
-Oil drain fitting for the oil pan, which i had to make myself due to poor flow otherwise.
-Something to plug the remaining oil drain hole, i used a 19mm freeze plug.
-Oil feed for turbo, 1/8NPT to 4AN 90° fitting + 4AN push lock fittings for lines.
(6466 don't need oil feed restrictor, it's already in there)
-Oil drain for turbo, 10AN fitting with an O-ring imbedded in there so no need for typical gasket + 10AN screw lock
fittings for lines.
-10AN enforced silicone drain line
-4AN enforced feed line
-2 x 6mm vacuum fittings for mac solenoid (i used 6mm screw locks or whatever they are called..)
-1 x vacuum fitting for compressor housing in desired size (i used 6mm push lock)
-2 x 90° push lock fittings on wastegate 6mm
-1 x screw lock T vacuum fitting 6mm
-6mm enforced vacuum lines
-Roll of heatshield tape
-Different sizes of heat sleeves for drain, feed and waterpump lines
-Box of different sized O-rings. Just because!

Manifold
-RB flange
-T4 divided flange
-7 x 1-1/2" Schedule 40 long radius 90° elbows 304 (1 for dump tube)
-2 x 1-1/2" schedule 40 Tee 304 (those T shaped parts)
-2 x M18x1.5 02 saddled sensor bungs 304

Dowpipe
-3-5/8" turbo discharge flange + clamp (depending on your exhaust side of turbo)
-3" 2 foot long pipe 304
-3" flex bellow 304
-3" 180° degree mandrel bend 304
-3" to 2x2,5" Y pipe 304 pre-welded to make things easy
-2 x 2,5" exhaust flanges to connect to original exhaust
-2 x M18x1.5 02 saddled sensor bungs 304-3" V-band flanges with clamp to make the downpipe in 2 pieces..

Even tho i'm not gonna make it in 2 pieces because it seems so pointless on such a short downpipe on a bottom mount..
I rather replace the V-band flanges with the flex part because otherwise i won't have any room at all for the flex bellow. (downpipe makes a small jump over motor mount)
I don't want my exhaust to stress the bolts on my turbine housing causing my turbine wheel hitting the housing itself overtime.

Turbo compressor outlet to intercooler
-2,5" cast aluminum 90° elbow to weld on compressor outlet
-2,5" aluminum pipe 1 meter long
-2,5" silicone couplers in the angles and quantities you desire + clamps of course.

Coolant pipe
-Coolant pipe flange, aluminum on ebay.
-Coolant flange gasket
-2 x aluminum 90° pipes 35mm
-135° 35mm silicone coupler hose, to connect coolant pipe to waterpump

Most of the manifold and downpipe parts come from ACE raceparts..

And of course you'll want these heat sink extenders aswel, so you won't fry your O2 sensors the first 100 miles lol.

Nice build. Very curious about wastegate placement. I have no idea where it could be.
On the turbo's turbine housing itself.
Like Maxiumum PSI did to their E46 M3 turbo kits.
Pic of that kit,

Wow awesome build, nice DIY stuff right here.

yeah, I mean I know its possible but I guess no one wants to undertake the task, it doesn't have a be pretty as long as the kit works I'm game

Once I get my hands on that SteedSpeed mani the wagons go under the knife!

Thanks!
Wish i could do equal length runners but simply can't due to my circumstances and lack of skill anyway :sweatsmile:
Would be great if this works out well, also for those who might want to try to DIY.

What's up with Vader Solutions? @Omar@VaderSolutions
Why has it been 3 weeks that i ordered my n54 breather system and it still hasn't been shipped?
This has been going on for a few months I think. My order was a month. I believe Omar posted somewhere that he's trying to get it straightened out. But I know folks still waiting on parts. In fact I shipped my Vader stuff to someone else who ordered on 2-day ship because they have yet to see it, and he wanted it to go to his builder along with the rest of the build. I'll just take my buddy's once it finally ships out to him.

Shipping alone to my country takes another 2-3 weeks + ridiculous tax fee.
