.......yea! I am going to turbo my E. Currently reinforcing the internals. Hoping to make it bomb prooof. I plan to do it right, but it is taking so much time because everything is being custom made as there are no pre-fabs for Mercedes.

Yatchmaster and Blown V8, you are quite right in that you cannot just use after market pistons because of the nicoseal coating on MB engines. So the cylinders are getting sleeved. Entire engine is essentially getting rebuilt for high boost tolerance.
JamE55, the pistons are locally custom made. They have taken 8 month to get them made.

Are the bores Nikasil or Alusil? If the bores are Nikasil coated, you can run an aluminum piston in the bore. If the bores are Alusil, you must run a coated piston.
Sounds like you are doing the right thing by sleeving the engine. That way, you don't have to worry about the bores and you can use JE pistons which are about 1/4 the cost of replacement Mahle's.

.............thanks. I decided to sleeve the cylinders partially for cylinde wall protection and partially to be able to run aftermarket low compression pistons. The cylinder walls in Mercedes engines including the AMG ones are amazingly thin. The engines were built no to be repaired or re-used.

Very nice Ted!! Glad to see your project moving along..
I am going through the exact same excercise.. In the process of building a 5.7L all-bore block.. We are re-sleeving with custom pistons and rods.
Can't wait to see how that TT beast turns out.. Good luck!!

It's actually called Nikasil - there are a number of reasons people don't do it. Saying it isn't possible is somewhat misleading - anything is possible - the reality is that it is cost prohibitive to have it done in most instances. Mercedes is not the only company to use this process on OEM engines. BMW used it on some of their V8s back in the late 80s, early 90s and started dropping motors left and right after the amounts of sulfur in fuels began rising and deteriorating the nikasel coasting. The process has been improved since then and fuels no longer contain as much sulfur.

And then the possible wait time on having pistons made and sleeving the blk sounds like a pain in the ***.

In that case it sounds like it would be better to just purchase a new AMG block with new stck pistons and rods if that's the case. The BMW V8 that first came out with the nikasil coating for the early V8 530's and 740's was such a disaster! Who could forget!

......Big PTA. However, my custom pistons, rods, sleeves are all done. Engine has been pt back together with Kleemann Kompressor and car is running fine. I had forgotten how wonderful this car is. I did this to prepare the car for twin turbo. Mmmmmm...me thinking now that I have a lower compression piston (8.5:1) I can just have a larger crankshaft pulley made ala W211 e55. Possibilities!

You mind me asking how much the rods and pistons set you back? You should put a smaller s/c pulley on the car since unlike 55k motors, the Kleemann pulley can be easily replaced. The problem you may run into is additional fueling for more air. GREAT work Ted! Cant wait to see your results!

Thanks Marcus. I am somewhat confused. Are you saying that stock E55 cylinder walls and/or pistions come with Nikasil coating which can deteriorate from sulfur which can be found in some fuels. Hence, the Nikasil coating may have been a bad idea to begin with. If this is the case, wouldnt it be better to remove the coating and place a sleeve in the cylinder.
The MB AMG blcks don't have the same problem apparently and they have aparently perfected the method which has been used for yrs now.

There is way to put a steel sleeve and still be able to use the stock pistons, it has been done before. The machine shop just needs to know what they are doing. A new short block is 12 thousand + dollars, you can't buy just the block.

Not a big fan of sleeving this block especially if I'm trying to make big HP.
I know Teddy B(Ted baldwin)
will be pioneering this but I'd have to see how long or how reliable the application would be. From what I remember PTE does not recommend it.
I would'nt put a sleeved blk in my car unless I owned a Honda.you have to sleeve those blcks when going F/I but those motors don't last,especially under high boost.
