[W126 Coupe] Aussie FrankenBenz Progress!

[Axel Wulff]

Sounds fantastic!
 
The W211 5.5L engine is based on the M113 V8, correct?
...and AMG added a kompressor (among other modifications).

Hi Mike R,
Like you I seem to have a never ending list of challenges to overcome fitting the W211 E55 AMG motor and trans into my ‘89SEC.
I’m still hoping to use the E55 gear shifter and accelerator pedal as they only require wiring.
My E55 motor is complete with all its accessories, so aircon compressor and power steering pump will upgraded. There is quite a big steering pump pressure difference [increase] that I’ll have to deal with somehow.
The fuel pumps go the other way with the 560 being too high.
My E55 5 speed trans is quite a bit shorter than the 560 4 speed and I’ve designed a coupling that will make up the difference as well as convert the AMG 4 bolt doughnut to the 3 bolt 560 tail shaft.
I’m at the stage of finishing the body work and suspension. Just a few weeks to go, I hope, then start the motor/trans swap.
I’m using 285/40/17 Kumho rear tyres , so I hope they will be able to tame the 469hp.
Like you, I’ve removed the SLS and fitted H&R springs at about 40mm lower [looks fantastic]. I had KYB Gas Adjust shocks but they are too soft and following Jonathan’s advice, I now have some Bilstein HD for the rear.
I’m not sure how the cruise control will end up. None of the 560 stuff I suspect and electronic from the MoTeC ECU.
I’m planning on keeping the 560 oil cooler and steering cooler but I have to fit in an intercooler radiator somewhere.
Moving the 560 oil cooler to the same position but on the left and fitting the intercooler in the right side will match the E55 plumbing better.
I’ve been planning and buying bits for about 3 years and it’s exciting to eventually be starting to do stuff.
 
Anyway, it’s all stuff to work on at night when sleep won’t come!

It's a race I'll likely lose. All I have to do is:

design and install a transmission shift linkage
design and install an accelerator pedal with cable
design and install a transmission mount
Move the battery to the trunk, do the wiring
Mount the PCM in place of the battery
Remove all Benz engine wiring
Wire up the engine with the new wiring harness
Install the new fuel pump, plumb it, get a fuel pressure regulator and install it and plumb it to the engine
Install the cruise control amplifier, hook it up electrically and mechanically
Get the new driveshaft made and installed
Install the alternator and AC compressor (stock or custom location, depending on fit), wire/plumb them
Install the SEC radiator, plumb it
Install the GM power steering pump, plumb it
Mount the new transmission cooler and plumb it
Mount the new oil cooler and plumb it
install the new Lorinser air dam on the front skin, paint it
install the new rocker panel pieces, paint them
remove the SLS hardware in the back, install the new non-SLS H&R springs and new Bilstein shocks
buy some new rims and tires capable of 185 mph
get an alignment

 

There's a dozen more tasks that will need to be done, but I've depressed myself enough with this list.
