I purchased these cams from a guy in germany with the intent to use them but I found out my car needed more work so no more HP for me:crybaby2: I was told that these were THE LAST SET NEW IN PLASTIC from Mercedes. I am selling them at cost and free shipping. That is $1400 OBO

Just talked to dealer... There are 8 of #25's left and there are 2 of the #24's left in Germany. They are +$1800 for the pair from Mercedes.

Rubber Ducky,
You need the 08-09 cams for your 500 engine. Dwell angle is different between the two number sets.

Time to put the "ECE conversion" to rest.

There is a lot of info about converting 560's to ECE specs, though I am not sure plopping ECE cams on a 10:1 motor is enough to bring it to spec. And recall US motors are 9:1, so you will not see the benefits much unless going 10:1 euro spec.

Weren't the ECE cams actually 16/17's while the 24/25's were the later 8-pin RuF engine versions? Same cam profile all around? On the surface, appears to be, so 822 cams were the same thing in the post '88-91 RuF cars?

Myths I have seen floating around, that need to be proved/disproved:

- "different distributor" - true or not?
- specific ezl - you see the -606 4-pin ezl used on 822-code cars. Though what about the later '88-91 560 8-pin universal EZL and 10:1 KAT engines? Do these cams work on these EZL setups w/o further mods? (see distributor myth above)

cascade's ECE motor runs on the US ezl and cams. I think it could stand to gain some more.

Rubber Ducky,

Just asking here, if I bought a 5.6, put the ECE pistons in, along with ECE cams, but used my Gen 1 intake and injection system, would I yield the same results? Or am I wasting my time?

I was also wondering how a 5.6 with ECE pistons and AMG spec heads/cams, and Gen 1 intake and injection would pan out as well.

Again, just asking here, I'm not that knowledgeable on the ECE/AMG motors.

I'm gonna have a friend of mine make custom headers for the new motor that will be going in. This thing needs a rebuild and its more cost effective to find a good shape used motor.

The ECE uses specific ignition mapping via CIS-E which your car does not have. If you were to go that far w/ a 560 motor w/ 500 top end, might as well go EFI and have complete control over ignition mapping.

So in other words, without the CIS-E, putting AMG heads on a 5.0 would be the best option for my car?

Yes. I have one ('84 500SEC) w/ AMG heads, pnp, and boy does it move wicked, even w/ a 2.24 LSD. So different temperament from the 560's. So you can't go wrong. Just be sure you do the idle speed adjustment with these heads.

Oh sweet. I really just want her to move more than she does now, and it seems a AMG motor is what I'm looking for. What I've always wondered, was how exactly did AMG make the 5.4 make 310HP? As in, what mods did they do to push it that far?

Gen I? Cams/heads/pistons/headers..likely some tweaking to the fuel distro, or @ the very least running the hotter of the two euro 500 fuel distros.

These cams are Really the way to go if you are running headers, they Wake the car up So, So nicely. You can get a solid map out of the US EZL, just going to want to have a resistor cap/settings to play with.

For 10:1 euro engines (>09.1987):
"RÜF cams (24/25)" + "other correcting plugs for KE and EZL/AKR" + "Tri-Y" - "catalyst" - "air pump" (+ "RÜF modulator for gearbox") = 300 HP.

Weren't the ECE cams actually 16/17's while the 24/25's were the later 8-pin RuF engine versions? Same cam profile all around? On the surface, appears to be, so 822 cams were the same thing in the post '88-91 RuF cars?
Yes, the ECE (S.A. #822) cams is 16/17, while 24/25 is for the RÜF (>09.1987, 10:1, EZL/AKR). This cams have identical profile (cams are identical).

Myths I have seen floating around, that need to be proved/disproved:

- "different distributor" - true or not?

N.B. ECE (code 822, 220 kW) was available only for pre-09.1987 models (EZL).

Different fuel distributor and air flow sensor is only between:
10:1 engines: [>09.1987, KAT (62/0)/RÜF (821), EZL/AKR] and [ECE (code 822, 220 kW), EZL] - at the one side
and
9.0:1 engines, EZL, <09.1987 [KAT (62/0)] and [RÜF (821)] - at the other side.

ECE used specific EZL ecu.
10:1 KAT/RÜF engines used same EZL/AKR ecu, but with different correcting plugs [RÜF - 0 Ω, KAT - ∞ Ω).

Distinctions between ECE (822) and KAT (178 kW)/RÜF (200 kW) see here:

Salutte!!! :):):)
