Forged pistons in the 113, gotta remember this is a very old engine and not only is it built like a brick sh1thouse but its battle hardened it can handle the boost pressures no problem whatsoever i can assure you in fact i will have to check but i have a funny feeling the pistons are the same PN for the whole series.

For the gearbox you can have the parts you want custom made if your really serious.

Cool that's what I wanted to know. See if you can check on the PN for the pistons to see if they are the same. I would think they have to be different just because of the compression difference between the SLK55 and the SL55. The SLK55 with high compression versions and the SL55 with low compression version.

The EPC was down today but i will have a look in the morning for ya.

one more PN you might want to check is if they have the same heads. That might be where they are changing the compression too.

Just like the Black Series its all just BS the car does not even have a fixed roof it simply has the standard 55 roof (in CF ) and its latched onto the windscreen frame and inside the trunk using the exact same clamps the only difference is the hydraulic system has been removed and the clamps locked.

The point is if any company wants to make a sale they need to find as many goodies as possible to attract buyers and saying here we have a SLK55 with the AMG Performance Package fitted / here we have a SLK55 Black is more enticing to buyers than simply SLK55, MB don't give a crap about performance or weight they care about profit only now you would not buy a car with a performance pack just because it has a higher limiter but throw in some wheels and it makes more sense to purchase it on top of the standard car.

If MB was really serious about performance then they would have gone BMW M3 CSL style reducing weight so much that the floor of the trunk is cardboard but they're not.

And there are lots of people who want to buy a car which can not be bought by 99,9% of the rest. For those, a "Dark Black Series" would be the best. They don´t care about performance of the price, they want to be different. And Mercedes is using this kind of density to make good money. I think, Mercedes is doing right

Exactly its about the exclusivity of the model not how it performs.

Different crankshaft and connecting rods mate.

SL parts made by MB SLK parts made by HWA

Checked the heads it was harder to tell because the SL has cylinder cut off and the SLK does not so the PN's are different for that reason however the left bank was identical on both engines so thats a good indicator.

Any luck on finding out if they use the same pistons?

Very true(good post), and this is the point that the speed racer crowd doesn't get. You'll see the comments "Well I bet the SL65 guy has to feel bad that he got beat by a Z06 which is half what he paid for his SL65". Well ah no he doesn't feel bad. Because the fact of the matter is if he wanted a Z06 he could buy two of them with what he paid for the SL65. And since he can afford a SL65 he more than likely can have a Z06 or some other in the garage also if he wanted. The simple fact is someone on a sub $15k sport bike can hand your azz to you if you just want to look at price to performance and call that an end to all means.

Thanks that is what I wanted to know that they use the same pistons. I am thinking about getting a Kleeman SC for my SLK55.

DansSlk · 06-27-2007

Ah OK.

Well it will be fine i know for a fact Kleeman put loads and loads of miles on the mules and so do Brabus and i am sure tuners such as Renntech do the same.

The engine is not going to go bang but your warranty will.

Who can you get to make a custom ring and pin for the rearend?

Don't have any solid contacts in the US i used a local company who works with Aston Martin and the Subaru WRC team to produce the parts i wanted for mine.

I did look into them making some more parts but they wanted more cash apparently it was not as clear cut as they expected knocking the parts out, and i had to supply OEM parts to be used as templates.

Hi All,

New to the forum and I found this thread extremely entertaining. I have a bone stock 350, 6 speed, sport suspension, Pilot Sport 2 and I regularly compete in local Auto cross events. The one thing I'm certain that mine does NOT need is more power. The limiting factor in my performance is traction. I can beat nearly all the other entries on street tires but those using soft sticky race compounds will be faster almost everytime.

Just an observation. Trying to increase power output would be last on my to do list after I'd taken care of tires/wheels, suspension mods, weight reduction and improving driver skills.
