Meet the 1995 BMW 540i/6 named Project Ares. It's a factory v8 & 6spd manual with 252k miles on the clock. Purchased 4 years ago non-running, it's been my daily driver ever since. It's rough but I still love it. The paint is tossed, there is a dent on every body panel. The interior was in bad shape. I've now taken this project way overboard from where I intended it to be, a comfy and fun cruiser to something in between street car and race car that's not really good at either of those things.

It currently has the original M60B40 4.0L v8, custom cam timing, lightweight flywheel, deleted accessories (No A.C, no P.S.) Original 6spd trans, E60 short shifter, 3.62:1 limited slip rear. Sitting on 18" E38 style 37 reproduction wheels that I just recently bent a rear wheel so a spare set of chromie 16"s will be mounted soon.

Gutted interior, single drivers seat. As much weight reduction as I could get away with.
It's running on a standlone do-it-yourself EFI called Speeduino, an Arduino based system.


Other than that it's got typical bolt on's; E-fans, underdrive pulley, single 3" exhaust with a Vibrant Ultra Quiet resonator and a Borla ProXS muffler. Ford 19lb yellow (Bosch GenIII) injectors.


I've started putting together a supercharged M62 4.4L V8, similar platform as what's in the car but more displacment. M60 heads and cams, head studs & MLS head gasket, Eaton M112 blower from a jaguar on an adapter to bolt down to the BMW heads.

Piston's sit .025" above deck and have a slight dish to them, roughly 4cc. Machined and rebuilt cyclinder heads displaced 52cc in the chambers. The HG is 1.74mm (.068") compressed thickness. By my calcs static compression will land around 9.5:1, but I live at 5400ft elevation with a generailzed baro around 12.2psi which makes compression act like an 8.3-8.5:1 at sea level. I'm aiming for 8psi with the Eaton M112.








 

...I haven't convinced myself quite yet to drop the S/C'd engine into this old E34. But, likely it will end up in there for a while to get some track days in. Thanks for checking out my project, I'll update as things progress.

i don't know where this is headed, but i love the possibilities.

Euro V8 + manual trans + blower + old BMW = so much win. This is a cool project.

Very cool.  Is the blower adapter something you designed yourself, or is it commercially available?

They are are machined by a member of the bmw forums. Not made in high volume and a well thought out kit.

A few other pics along the way:

 

Had a Spec brand clutch disc sieze to the pressure plate. I hated the way the kevlar disc felt on the street so I went with an O.E. Luk brand and feels much better:

Took the car to the drag strip that weekend for filming of the TV show Roadkill for their Zip-Tie drags:

A month or so later while driving around my town I hit a patch of uneven pavment that did some damage, hurt an axle, hurt a diff and bent a rim. Installed new axles and changed the diff out from 2.93 open rear to the 3.62:1 LSD.

Before installing the standalone EFI I spent a good part of my life learning how to read the hex code and tune the original Bosch Motronic System:

I was able to identify 60ish tables out of the 130 tables in the code

The motronic system was just too limited to accomplish what I wanted and I made the decision to jump over to standalone. Still working the bugs out of that system but I enjoy it much more

The MAP based speed density system was also in anticipation of the boost of the new engine.

Where do you start to identify tables from a hex dump, I have a mitsubishi file I have been on and off looking at for a few years now but I have no clue where to start once I get the file off.

 

Thanks,

I wouldn't know what to tell you on that platform.
