There is a whole thread that he created for this swap.
You should go read it.

BC.

 

Wow, good luck keeping me and tom as friends when you start posting that garbage. LOL Oh and Steve too now that he has one.

 

I cant see that happening lol

 

Got to see this bad boy today, amazing job on this swap! I had a few SL55 intake tubes from my set up that I was not using and donated them to Lantana to try out. On the way to my house to pick them up, we had a small contest between the V8 and my SRT6. It was misting rain so we had to start in the 50-60 mph range just so I can hook up. I let out of it at about 120mph, the V8 was well behind me. Not to sure how far back he was, I will let Lantana make that call. I think he would have a good chance against a stock SRT6, but I think he will need that turbo to hang with a modded one.

The exhast note on that car is worth the price alone and the potential of modding that V8 would be exciting. As soon as he gets the turbo on, I would agree to a rematch!

 

Can't say that result suprised me, people are to caught up thinking that anything V8 is super fast, in reality thats not the case.

The R171 SLK55 is an absloute beast, it has simular specs to a Crossfire in terms of size and weight (abit heavier then ours, I think), but far more advance in terms of LSD diff, 7 speed tranny, and not to mention a monster engine. they are a mid 12 second car, stock.

I'll go out on a limb and say Lantana's car would be a mid 13 second car at best in stock form. However as stated the potential is massive so hopefully we'll see mid 10 second car after a few turbos are strapped on

 

Have another couple of thousand miles on it and still all good with no problems at all. A fellow DFW member gave me some intake tubes from a SL55 which was a big help. I was running the stock V6 tubes which were way to too small. I removed the plastic parts in each side of the radiator that the stock tubes hook up too. Before the change it sounded like a vacum cleaner sucking sound at high RPM's. With the SL55 tubes it sounds like a healthy V8 all the way to redline. Not sure how much power the it was costing me but feels and sounds better now.

 

soooo very cool.
I myself have done lots of I6 swap outs for both SM & BB V8's, but only pre OBD day engines. Only now have I started to cross this bridge. My plans are to put a 89mustang GT motor in my 66 mustang coupe body which will require some minor electrical work.

Your XF is WAY cooler. Especially knowing all the electronical (is electronical a word lol?)mods you probaly had to do.

Question for you;

How did you deal with all the electronics? Which parts from the Xf and benz did you marry and did you need to program?
thanks, and again.....CONGRADS, sounds like a sound machine.

 

I used MB engine, computer and wiring harness from a CL500

The SL55 intake tubes made a great difference! May have to have that rematch sooner than latter how about from a dead stop?? I was using the stock N/A V6 tubes pushed inside the the air cleaner inlets instead of going around them. I also still had the V6 plastc parts with the very small opening on each side of the radiator. With the V6 intake tubes the engine sounded like a Hoover vacum from 5,000 rpm up. Now it sounds and runs much better.

I did have a major accomplishment last week. I took it in for its annual inspection and it passed just fine. In Texas they don't snif OBDII cars but they do hook up to the OBDII port. the CL500 computer told the state system the right VIN number and all checks passed!

 

very cool

nice job.

 

Just found this post..............I think Beaner will be changing his tune soon. With any luck he'll be bringing one back from St Louis!
