Topic: 450sel 5.0ltr 500sel engine !!!

OK, how about a modern 5L V8 at 400bhp!

You could use an AMG SL73 engine.  7.3 liters and 525hp.  Or the newer S-class 6.0L with 621hp.  It all just depends how ridiculous you want to be.

All perfect for around town   Clarkson would approve.

Very nice conversion. Two weeks for a professional or person close to being a professional, I'd say. Well done. But what is the motivation? Is it for the fun of it, or just a spare mint W116 chassis?

When my 6,9 engine is dead, I think it'll be replaced by a modern 3 litre turbo diesel - same torque, nearly the same power, and 2-3 times improved fuel economy. Or how about an electric conversion - plenty of space under the bonnet or where the fueld tank goes - ideal for those of us who do 50 mile trips tops.

Thanks, it is awesome, I could have done it faster, I just did not have time inbetween fixing other ppls Mercedes. It's what I do for a living : )
It is my sign written advertising car, I drive it everywhere, now I can show off the big 5.0, people realy get a buzz out of it.
Thanks for your comments.

how is the 5.0 going? Any teething problems?

Only oil filter housing was just touching on the engine mount, I cut a very small v in the side of the mounts metal section. It has proven a very solid conversion.

X2 for the pics and vids.

That is a sweet job!  What year car is the 5.0 from?

[450sel5.0]

This is such a cool conversion! Did you keep the 4 speed box from the 500 as well?

Tks,

Joe

Sure did, Sorry for the long wait on the reply.

No Problems at all,
Thanks.

Nice job. Any stats on mpg, etc.

Lots of fuel, lots of fun

what did you do re the speedo ?

I know the povo version cars that use that transmission housing such as the 190 etc use a cable operated speedo extension housing that you can bolt straight onto the v8s' 4 speed auto. or did you do something else? as correct me if im wrong, all w126s had electronic speedos ?

I have installed a speedo from a late W107 and connected the electronic pick up on the transmission to it.

Good grief Adam, a 6.9 needs to stay a 6.9 and there is no shortage of engines for them (I have one for sale on CL right now for $650 and there's another fellow down the road that's selling one for around that price too).
If you want to mess around, there are plenty of W116's to do a similar conversion to.

I bet that the oil filter housing can be transplanted from the older 4.5 M117 to the new one, but personally, as I have an oil extractor, I'd rather pull the battery tray and get it from the top.

If you want to mess around, there are plenty of W116's to do a similar conversion to.

Not every W116 has hydropneumatic suspension.    And an engine from a 300TD with the SLS head can drive it.  Use the oil pans from a 300SD to get the clearance for a 116, and various linkages from the 300SD that were different on the later 617-based models, and you have quite an interesting, original-looking result.  I've toyed with this idea for a long time.

So?.
