For example a Coyote 5 liter with the 6R80 auto trans, aftermarket ECU and a US Shift TCU. The usual problem would be getting the dash etc to work. People are doing things like putting a Nissan 370Z engine into a BMW and using Audino talking with the canbus to make it all work but that stuff is beyond me. Generally does the Xfire's electronic sensors match up pretty well with later US engines? Using a Merc V8 is not practical for my AU situation.

 

I am partial to the Mercedes, and My V8 crossfire is then 2010, and now2024 the world's fastest crossfire in the 1/4 mile 10.55 @132.
also the cost per time finding all the quirks to get a chevy, ford, or hemi engine and tranny to fit and work
to Install a Mercedes engine (mounts fit) (V8 transmission fits) (drives shaft fits) , and with 600hp it all stays together
for at least 634 1/4 miles runs at the drag strip,,, I have a friend that put in a chevy ,, car still does not drive after 2 1/2 years
I am now on my third Mercedes build, and with Rudy and Josh helping with tuning and little things that we know that work so well
this new V8 crossfire that i have (have not taken to the track in 9 months now ,,throat cancer and skin cancer,,beat them both
that is cancer # 4 ,, back to the car,, this one is a little faster than the last two, I took it on I-95 and at 80 mph punch it, hold it, time it,,,
the 10.55 car went from 80 to 150mph in 7 seconds. this newest hits 150 in 6 seconds,,, LOL you ever try to watch
a stop watch and drive at 150mph, I95 in Florida is nice and flat , I am waiting for the 1/2 mile roll run next year to see what it will do in the 1/2 mile
well to my point the Mercedes swap is easer and faster,,with time even cheaper. jim

 

You keep coming up with these super complicated swaps, instead of what is practical, and we know works. As someone who is a hot rodder at heart, and has done numerous swaps, sometimes simple is the right answer. 5.0L M113's are super cheap, and not overly complicated to drop in. The 5.4 is the much better choice, and just as easy to swap.

You got right to the core of the area you are going to be weakest in, and that is the CAN bus. Oh, and it's not just the dash you will need to worry about. It's the AAC, ESP, PSE, AB and more. As for the Coyote, have you ever taken a tape measure to one? Do that, then go look at the CF.

Sorry to be harsh, but I think this is beyond what you really want to get involved with. Do a 'simple' M113 swap, then maybe think about something exotic, like M137/M275 if you want to really take on a challenge of something no one has tried before in a CF.

 

Thanks for the advice Neil, if I can't find a SRT coupe then the M113 conversion into a base model option will be the alternative choice.

 

Not trying to down you. Just trying to keep the project completion disappointment level manageable from someone who has bitten off more than they can chew in the past.

 

Understand Neil, thanks.

 

Another alternative would be to put the much more obtainable 5 liter M113 into a lighter R170 SLK for more performance. Wiring and electronics would be very similar I guess.

 

SLK R170 swap is nearly identical to a CF swap, so yes, it will work just fine - except, it needs to be a "facelift" R170, not a pre-2001 4 cylinder. The chassis is indeed different. You can do it on a 98-2000, but it is a LOT more difficult.

 

Have you looked into any local shops that specialize in these swaps?

 

I don't know of any shops in AU that do Merc V8 swaps.
