I have changed a 320 (same) loom and have the old one here, so I can guide you if/when you get stuck.

Take it slowly , don't give yourself any unrealistic daily or weekly targets . Sometimes the slower you go , the quicker you go , if you get my drift ?

Don't forget we are all here for you ........ and practice your uploading of pictures !!!

what are you doing with the 300SL engine? Im looking for an R107 engine to put into a W115.

Sorry had not checked this thread for a while. I am probably going to keep the engine for bit incase the car turns out to be rubbish as a 36SL and I want to put it back ! Also in case I have it 50 years and matching number classic R107s are insanely valuable. Of course I might get fed up looking at it and then sell it before then!

A little bit of progress, although the engine is still not out I did a bit this weekend inbetween rain showers. The main finding is the gear shifters use the same mounting point so that is one worry gone. Rounded off a couple of screws when removing the engine bay wiring so that will slow me up a bit.

Excuse me joining this thread at a late date. I'm toying with a 107 transplant but using a 300 TD for torque and economy. (and the fact that I hate petrol engines). I've been told that fitting the 5speed electronic box into what was a 4speed is a non-starter (no pun) cos the roadspeed inputs are missing and also the diff ratio has to be the same as the donor or the box wont change up. Is this bum info? Also, the ignition and immobiliser module requirement is puting me off. Is there a way around having to use these?
I'm easy with electrics but draw the line at canbus.

Great thread. Please keep it updated.:thumb:

There's a company in germany called Mechatronic (?) I think who do exactly this kind of thing. I will dig out the website for you later. I think as long as you have both cars in front of you in their entirety it should be possible with time and effort in terms of the 300TD conversion.

I think you need to keep the immobiliser / ignition key bit but this is just another module to wire in around the car so should not be that big of a deal.

I thought the gearbox problem happened when you change from a 4 speed to 5 speed on the same engine as the engine speed pick ups are different, if you take the 5 speed and engine from the same car it should work. Happy to be corrected on this (actually not happy as it makes life a little more difficult)

Cheers Ben. I'm not going to even try to 'correct' you cos I simply don't know, but I'm told that a 5speed takes road speed data from the ABS ecu on the host vehicle. If this is the case does the ABS ecu on a 107 have the required output? I would doubt it. Very happy to be corrected on this cos it would make my proposed conversion simple(r). The 4 speed won't work with the turboD engine cos it needs a modulated vacuum input which the turbo engine doesn't have. If the 5speed does need an ABS input I'm really stuffed cos my car doesn't have ABS. I've got a Getrag 5speed manual in the garage which would fit the engine but then I need a flywheel/clutch which the 300TD never had. I would also then have to change the diff ratio cos the Getrag is direct drive in 5th and the engine would be howling at legal limits.

Welcome to Mechatronik - The spirit of classic - specialized on Mercedes Classic Cars

I recall in Merc Enthusiast Mag did an article on a 300 SLR conversion with the e36/C36 engine brakes and gearbox, it tops out around 170mph and stops like a modern car. The conversion was designed with a straight 6 engine so the original components can be put back at a later stage should the car need to be put back to authentic spec. I understand the sultan of Brunei has some V8 converted 300 SLR's but the cars can not be swithed back to the straight 6 without major surgery.

just found the PDF link

Worst case is I have the ABS pump, computer and loom from the C36 so can transplant them if necessary. My SL has ABS already so should not be impossible.

That's the way to go. I would be nice to know for definite all the same. Would help my problem no end if a 5speed could work (with it's donor engine) on it's own without ABS inputs.

maybe a stupid idea but cant you just disconnect the ABS sensors/more abs stuff on the donor car to see if it has any ill effects with the gearchange?

That is a good idea, sadly a few months late for me but should work for Druk.

It is a good idea but I'm not sure any donor car acquired by Druk would be in sufficiently road worthy state to be able to be tested.
