To start, I have (sort of still do own) a P31 car

I'm looking at replacements and just had the VIN decoded. The vin decode shows the car is a P30 on a 2012 model car NOT P31

But
It DOES have 22P Track Package, red brakes, LSD, sport suspension, and most importantly TITANIUM colored intake manifold vs Silver

I honestly thought the P30 was for 2011 and DOWN, while P31 was 2012 +
And I also thought P31 was the only was to tell.

I am aware that the P31 engines had lighter and forged internals from the SLS.... Can anyone confirm or deny that the titanium intake tells you this?
Or just engine stamp.....

I'm buying the car out of state and hard to get info
Thanks

I have a 2013 model with P30 and AMG performance package and titanium coloured intake. It was my understanding these three things show it has the 358kw motor with the forged and lightened internals.

95gsrturbo

Then what is a P31? LOL

95gsrturbo

I mean if this car has the forged and lightened internals....
What does a P31 do differently

BLKROKT

It is a PP car. All datacards show P30, regardless of whether it's a P30 or P31.

A search would have told you this

Valvestud

Here's what's included based on the 2009 and 2011 model years. Note that the nomenclature was changed from P30 to P31, but always shows P30 on datacard.

Here's the 2013 Coupe order guide - refer slide 16 which shows the codes that make up the P31 package. Note that the LSD is not included in the package but is a stand alone option.

Then why doesn't your datasheet say P31?

This is my question.
How can you know for sure - without seeing the engine stamp that it's a P31 ?

95gsrturbo

Then please explain the difference
Why are there 2 different codes?

This helps A LOT
Thanks

Post your VIN that showed P31. I've pulled many, many, over multiple model years. None have a P31.

The P31 is simply an option package. It like others such as P01 don't show up on datacard. There is no identifier on the car that denotes the package.

I stand corrected --DEEPLY SORRY
ValveStud you were the one who decoded my vin originally, I didn't remember it correctly - its attached below

Thank you for correcting me

So that we are all clear 2012+ models with FL which have a P30 code will all have lighter weight and forged internals? Yes / No

BLKROKT

Depends on who you believe. AMG will tell you in their marketing that the P31 cars have lightweight forged crank, rods and pistons. Tasos on YouTube has taken apart a P31 and I believe that the crank was no different from the non-P30/31 models, maybe the rods too. Jury is still out on the question...

Sorry, edit. He took apart a 507 engine which is the same as a P31, confirmed by Tasos. It had the SLS crankshaft and pistons. Regular rods, no different from any other C63. Videos below.

And this is what I was looking for
I'm looking up Tasos next
Thanks

PRESS RELEASE

Performance Package Plus: enhanced performance for successful AMG model: C 63 AMG with a shot of SLS

Affalterbach – Enhanced driving dynamics ex factory for the Mercedes-Benz C 63 AMG: the new Performance Package Plus is an attractive optional extra that is designed to appeal to the power-hungry sports driver. The Performance Package Plus increases output by 22 kW/30 hp to 358 kW/487 hp. As a result, the C-Class approaches the level of performance offered by C-Class DTM vehicles, which deliver 377 kW/500 hp. The Performance Package Plus is available for the saloon and estate models and includes an AMG high-performance braking system featuring composite technology on the front axle, a carbon fibre spoiler lip (saloon) and an AMG performance steering wheel in nappa leather/Alcantara.

With the Performance Package Plus, the C 63 AMG accelerates from 0 to 100 km/h in 4.4 seconds and 0 to 200 km/h in 13.9 seconds. This beats the 336 kW/457 hp standard model by up to 1.2 seconds (0–100 km/h: 4.5 seconds; 0–200 km/h: 15.2 seconds). The top speed is 250 km/h (electronically limited).

The improvement in power output to 358 kW/487 hp is due to the AMG 6.3-litre V8 engine's modified engine compartment: the forged pistons adopted from the new SLS AMG super sports car together with new connecting rods and a lightweight crankshaft translate into a weight saving of three kilograms. Reduced inertia boosts the agility and responsiveness of the uprated V8 engine, which is recognisable from the variable intake manifold painted in titanium grey. New engine management completes the powertrain measures in the Performance Package Plus for the C 63 AMG.

Exactly. The rods are not different. AMG marketing are liars.

MBNRG

Conclusions drawn from above 2 Tasos' videos provided by BLKROKT, in addition to:


C63 Performance Package (2014 507 used as reference here, per Tasos' videos) has:

1. Upgraded Crankshaft from SLS (Non-Black Series), with weight savings of 4.96lb over the 2008 C63 (I assume Non-Performance Package)

2. Upraded Mahle brand Pistons from SLS (Non-Black Series), with different/lighter Wrist Pins, with total weight savings of 1.2lb (8 of them) over the 2008 C63

3. Same Connecting Rods as the 2008 C63. Tasos does not mention if these are the same Con Rods as in SLS or not. Perhaps AMG Marketing is still correct? :P

Maybe someone with Mercedes EPC access can check Con Rod part numbers for a PP C63 vs SLS (Non-BS)

Vladds

So here's how the part numbers look like:
They start with A1560300820, then they go through 5 generations..
This is weird, these engines must have a problem with con rods that these people were trying to solve.
The latest that I can see is 1560301220
Then there is (mind you for the 204 series) 1590300020
In the description for this part number, I see:
Output increase option 923
Special model AMG Black series P98
Option P61

I see that Output increase 923 is part of the P31 package. P61 is 507.


Now all these 3 have as a pre-requisite 204 model series, meaning, these con rods are not available in a M156 in a G series or S series, only in the W204.

MBNRG

Vladds - The Connecting Rod with Part #: 1590300020 is in all 3 C63 variants - Performance Package (Output Increase Option 923), Black Series, and 507 Edition, correct?
Does it mention the Year this part went into production or was made available?

This same 1590300020 Con Rod - is it also in the SLS?
The 159* designation makes me think it may be

95gsrturbo

Do you happen to have a similar .pdf for later model years?
2013-2015 to compare the package of the p31, p61 and black series (i think its p90? )

just curious what the difference was beside aesthetics in the hood steering wheel, shift knob, and cluster

Thank you

Here's a couple that might help you. One is attached the other is too large to attach... https://www.dropbox.com/s/nv8hv4oh5h...dec14.pdf?dl=0
