寶馬S54B32直列6缸發(fā)動機(jī)

The pinnacle of the apex of the vortex of motoports engineering - this is the BMW S54B32.
For those unfamiliar the BMW S54 motor came in the E46 M3 (2000-2006), Z3 M Coupe/Convertible (2000-2002), and Z4 M Coupe/Convertible (2006-2008). It is a wolf in sheep's clothing, a high-strung race motor put into a road car chassis, and now its available for you to print!
File includes .STL files for the S54 long block as well as the engine stand. The S54 files included are scaled at 100%. Simply scale down the engine parts to suit the size of your build platform, I printed at 25% (1:4). Engine stand is scaled at 1:4, so if you are printing at a larger scale do keep that in mind.
Total print time on my printer was ~60 hou, so relatively speaking this is not a time couming project.
MINOR UPDATE
For some reason there is no photo preview of the cylinder head but it should still be included in the download of all the files, or you can find it under the "Thing Files" tab and download it that way.
I also uploaded an updated engine stand plate that bolts directly to the back of the motor, eliminating the need for the fragile arms.
Hardware required:
M3x22mm 14x for cylinder head bolts
M3x12mm 4x for engine arm bolts
M3x10mm 12x for valve cover
0-80 x 3/16" 25x for oil pan
0-80 x 3/8" 10x for front/rear cove
0-80 x 1/2" 10x for front/rear cove
0.050" Hex key
2.5mm Hex key
Some holes might require 'cleaning up' with a drill bit, 1/16" for the 0-80 bolts and a 1/8" bit for the M3 bolts - standard size bits.
Stay tuned as I will be updating this with heade, the original ITBs and airbox, and more!
Happy printing!
