463 ENGINE TRANSPLANT
Couldn't find an existing Forum string........It may be considered sacrilege, but I'm sure it happens.
I'm looking to put a Euro5 [petrol] or Euro6 [diesel] into my 1991 463 petrol 300GEL - I'd prefer petrol, but will go with the simplest option.
I had a full engine rebuild by CREWE ENGINES 20,000 miles ago and the car runs beautifully. But.....
I live in London, so I'm very aware that in a couple of years I won't be able to go inside the North / South Circular without paying....and a year after that, I won't even be able to leave my driveway. I don't want to get rid of the car, so trying to plan ahead. Realise it will cost a bit, but
Any advice / pointers?
For instance, I'm looking at something like this 2016 OM642 LS SCR EU6-B > https://www.ebay.ie/itm/ENGINE-Mercedes-Benz-GLS-2016-On-350-D-3-0-Diesel-Automatic-WARRANTY-11179538/352783866020?hash=item52238e98a4:g:QPwAAOSwkzRddinJ
Are there any specific engines that I could look out for that would work? Realise it will be a lot more than just getting the engine mounts compatable, but at least there is plenty of space in the engine bay.
Thanks, Alastair.
I guess I have the OM642 in my 2012 G350. Really nice. As a V6 it matches the other MB V6s I have had and is a good combination of economy and efficiency. So I think a diesel V6 is a better option than a petrol one and not as mad as a V8, where I would go for petrol.
Now, in the G350, it has AdBlue to provide NOX emission control. It injects Urea into the exhaust or something to convert back to water. Nice idea, but does add a few bits of complication if you were thinking of adding that it - it needs NOX sensors in the exhaust and a AdBlue reservoir tank etc.
But if you get an engine which is Euro6 (diesel) without the AdBlue idea, then go for it. Pretty sure MB put them in a lot of motors, like the ML, so you should find some. You might need a different sump apparently - others will need to comment about that.
Good luck
Great care needed here. Tfl may consider your 1991 petrol 463 allways a petrol 1991 no matter what you do to it - type approval for the chassis???
Do not change the engine untill you are apsolutly certain that it is complient with Tfl.
my guess: you need to replace engine, gearbox, exhaust and introduce electronics; this needs a lot of know-how; probably easier to sell your car and buy an Euro 6 Diesel; probably cheaper as well if you take resell value into consideration.
In 2031 (40 years old) your vehicle will be in the 'historic' vehicle tax class and therefore exempt from ULEZ.
LPG?
good thinking but do you get it certified as Euro 6?
Please use this string. Other 3 are will be removed.
