How Close is the Crossfire to the SLK?

I was looking at the Crossfire service manual which is available as a pdf over at the crossfire forum. Looking at the suspension diagrams, things look VERY familiar. Is there any guide to transferable/interchange parts? Wondering if we can benefit from buying cheaper parts at the Chrysler dealer? I doubt any of the dealers have very deep inventories, given the short lifespan of the Crossfire.

I occasionally fantasize about getting an AMG engine in my SLK320... easier/cheaper to buy an SLK32, I know. But my car is paid for, and in perfect condition. I keep seeing the occasional Crossfire SRT6 going cheap and start to think about swaps... Anyone investigated this?

i use the crossfire manual daily it seems. other than the body and some interior its the same. i use the srt-6 to buy parts for my slk32.
with the mods needed the swap is iladvised. and slk32 arent that expensive now! i paid 16,750 for mine with 36k and steve1911 paid 17,500 for his with 11k on the meter!

Fit and finish is much better on the Mercedes interior. The Crossfire I test drove performed very well. IIRC the Crossfire convertible had significantly less trunk space.

Same chassis, different sheet metal............ :eek:

The SRT version is supposed to have 330 hp rather than the 349 hp of the 32, but if ///AMG actually limited the power is open to debate.

the SRT engine is the same and marked AMG under the chrysler engine cover. I have done extensive work on my Crossfire and they are exactly the same as the SKK320 R170. No Chrysler parts on the car. fit and finish of the Crossfire is as good as the SLK. the Crossfire is also built in the same factory. I have done extensive modifications to my Crossife including installing a V8 from a CL500. I have upgraded the suspension with parts meant for a SLK including vogtland springs, KYB shocks and installed SLK32 rotors with CL500 four piston MB/Brembo calipers.

Here you go. Engine is from a CL500 but any 113 V8 engine will work. Since the Crossfire is a 170 chassis this conversion would work on any R170 SLK. C Class wooul also very be very similar. This conversion does not have to cost a fortune either.

The mechanical part of this swap is pretty straight forward but the hardest part is all the coding and programing. To program the car you have to use the Mercedes STAR Diagnostic system in developer mode. Most shops that have the STAR system don't even know about developer mode. Every STAR system has developer mode but it takes a special security key to activate it. Developer mode is also only in German and is used by the factory engineers when developing prototypes and new cars. Krause's automotive have been working with me on the electronic part of the swap. If you are interested in an engine swap you should contact Robert Krause as he is very reasonable and knows how to do this. the average shop would probably not want to do this and if they did you could end up paying a fortune in the hours it takes someone else to figure everything out. With R170's and C class cars reasonably priced and nice engines on Ebay, this doesn't have to cost as much as people assume.

If you bought the parts and had them shipped there you could drive down and two days latter be driving a very fast car back home. The swap takes about 1.3 days and the programing takes about two hours.

Here is a link to all the documentation you would ever need.

Crossfire SRT6 Documentation Collection

The Crossfire's are virtually identical to the the SLK32's and SLK320's so the most of the manuals will apply to the MB's as well. We haven't seen prices cheaper at Chrysler in fact I buy most of my parts at MB. Everytime I have bought a part from Chrysler the part is in a Mercedes box with a Chrysler part number sticker stuck over the MB part number. When buying parts they always want a VIN number. One trick we Crossfire owners do is go on Ebay and grab a VIN number from an SLK that is listed for sale. This is a lot easier than trying to explain to the MB parts guy that I have a Crossfire. The same would work in reverse if you SLK guys want to buy parts from the Chyrsler dealer.
