Interesting. We looked at this in my W114 but concluded possibly too many issues.

Plenty of W124 estate petrol engines around!

Indeed! If you can source an early model (mine is -93) they also have under-piston oil squirters.

People in the know say that Mercedes policy was to make the first versions of a model to high specs and then reduce the features in later models for cost saving purposes ;)

I did not face any particular issues above the ones you usually have when swapping in a computer controlled EFI engine to oldskool chassis. Or some mechanical, like length of the propshaft, exhaust manifold/downpipe routing, gas pedal, length of gear levers etc.

Mine was a non-ASR, non-immobiliser and 5 speed manual which makes things a bit more easy.

The only thing I struggled the most with was the vehicle speed signal to ECU. It origins from ABS and is needed to pass the rev limiter of 4000rpm's when standstill. I realised it only goes for auto's.

Also, understanding the HFM-injection where you cannot adjust the idle. Another ECU box does that.

My first thought on encountering this thread yesterday - It can be done!
Second thought - where was this thread when it was needed? (LHD though so not strictly comparable and steering / exhaust clearance would have to be resolved from scratch).

Thanks hismajestics - and impressive work.
BTW - Firehawks don't last long. Michelin PSs are worth the extra money in that regard.
 
Attn. moderator: can this thread be moved to MB Clubs projects to be continued with other mods than just engine?
