I'm not sure what to expect ..... I will list all my mods for anybody to give me a estimate ..... but the most important for me is better performance and that I know things a in good shape ..... a bit way to go still ..... but not long now )
Also notice the build is on track ….. here are my new Bosch EV14 52lb/550cc injectors 48 mm. … only concern is that they are some millimeters longer than originals but I hope that’s OK ??
This is my home-made looped fuel rail. I went another way than most other since I did not fancy a hose going under the supercharger and laying on top of the hot engine.
I think this looks more aesthetic correct but it does mean I have to cut in the plastic cover for the engine ….. but I’m sure I can make it look sharp!
After getting it back I decide to get the AMG letters off since I don’t like them ….. heating them up slowly and when going off slowly another mark appeared,
I did contact Renntech reading acquiring some new marks and a gasket and they informed me it is one of the earlier models which has been discontinued. They will get back to me regarding this …. yet …… all-in-all I think it’s beautiful piece ……
As you can see then I had a big help from my son on 3½ ……. He was bringing me all the important tools you need when putting a newly renovated AMG engine in a car; such as crowbar and big hammer etc. ))))
last couple pic. – engine in – finished – closing up and going home dady)) ha ha ha ……
Great pics and can't wait to see the numbers. very nice build. Been following it for quite some time (like everyone else here) I think it's great that your son is hanging out with you through the installation.
^ love it. Little Viktor or should I say big Viktor is already getting involved with dad. Won't be so long and he will be asking for the keys to the SL.

ohh yes - he already do
You once talked about a pipe that need some extra isolation under the engine? Was it for hydraulic? The one I picture here? I gave the pipe some extra heat protection as the original one was in pure shape .... also I don't understand EPC showing a sealring .... number 385? These kind of joints don't use sealrings ...

Yeah love it big time
Damn! We are on the opposite side of the Atlantic and I kid you not, I woke up early this morning thinking about you dropping the engine back in without considering more heat protection for the AC line.
I have Shorty headers similar to yours. After many years, a tech noted that the insulation on my AC line was burning off. He thought it was because the headers are higher and closer to the AC line than the stock exhaust manifold. I have since wrapped the AC line with additional heat protection. I used some stuff similar to this. http://www.autoanything.com/air-inta...FQkOaQodgZ4Dqg
Well – by coincident I had to take air filters and coil pack off the engine again. Reason was that I had to use more force than I liked to get the exhaust to fit underneath the car ….. I had to push it up … like it was a degree or two out of alignment. I then decided to loosen all the bolts for the exhaust manifold and for that I had to remove quiet a lot for access.
I then seize the opportunity and wrapped the AC lines. (mousse had already eaten the isolation on the line that go into the car) No doubt that extra isolation is needed after the headers has been change … they come very close to AC lines –
Driveshaft on …. Not much room underneath for tools and big stomachs … ha ha ha … also the driveshaft in the back at the diff. … it looks like something has been grinding in the bushing
Not so many pics. from underneath since it’s kind of difficult to take due to the low working height I have. However, I hope people get some out of it even its many close-ups.
Assembling the exhaust was a time-consuming task … especially the three bolts with the cat. Almost impossible to do alone ….. key falling off underneath all the time …crawling under and up again ….. would love to have a lift )
Then time for the heat exchangers ….. this is going to be some modification and I have been reading a lot here on the forum. I am very pleased to see how members are helping each other to achieve the best solution. Now there’s more than one solution to a problem and the one I follow do not have to be the only correct one so any suggestions, then please come forward.
I have decided to divide the cooling system for the engine and the IC - the IC getting its own cooling reservoir. Also, a new Johnson pump which should be running all the time and an extra heat exchanger; in sequence with the exist, for the IC will be installed. Down to the locale boat shop which had all I needed.
The first thing I did was to separate the IC and the engine’s hoses. There is a “H” interface coming from the cooling reservoir – that “H” had to go and instead some brass fittings will sum it all up. Engine cooling only needed a connecting piece and then this was finished.
The IC needed also a connecting piece but with a “T” as it will need a supply from a new reservoir. (yes I know the nipple for the new resoservoir is too big - it will be change)
Finally have the understanding of the cooling systems … I hope …
Took me some time to figure this out ….. what cooler that goes to what but when you finally have the understanding, then it is much easier to make the right decision what to do.
• I have decided to split the cooling systems; one for the engine and one for the intercooler. Both systems having pressure reservoirs.
• I have decided to change the original Bosh pump with a Johnson pump. Pump has to run all the time – thou with a start-of-the-car delay.
• I have decided to remove the steering oil cooler as hoses and pipes into the cooler are blocking for the air-intake. Instead I buy another cooler (A215 500 00 00) for this and place it on the left side behind the fog light.
• I have decided to reroute the ABC Oil Cooler as it takes up space needed for another set-up. I will place it on the right side just behind the fog light.
• I have decided to reroute the oil cooler for the engine. It will be mounted on top of the crash-bar.
• I have decided to fabricated and install a special U-cooler/reservoir for the IC of my own creation. (Extra Low Temperature Cooler - Stage 1) It will be placed behind the crash-bar.
• I have decided to install an extra low temperature cooler for the IC (Extra Low Temperature Cooler - Stage 2)
• I have decided to install two fans on the Extra Low Temperature Cooler - Stage 2 - being thermostatic controlled.
I bought a used cooler on eBay (A215 500 00 00) replacing the original steering oil cooler as the pipes/hoses and the exist cooler itself is blocking the air-intake for the engine on the left side
First thing is to mounted the cooler and I was lucky enough to find an aluminium plate in an old Volvo – it’s thick and just what I needed.
Some cut & past and then the new cooler is in place behind the fog light.
After the new steering oil cooler has be assembled it was time to remove the exist. Easy fix again as it’s all made in aluminium and hoses just connected with clamp ….. fasting had to be rearrange but no hokus pokus at all.
Then it was time to reassigning the ABC Oil cooler to make room in the front for more special cooling stuff
The exist cooler is to be placed on the right side of the car – just inverted the steering oil cooler.
Again, using the same scrap aluminium as before I made a bracket for the cooler and mounted it on the bracket for the air pump – slightly tilting the cooler.
It’s have been a while since I last posted here on the forum but other things had priority. It does not mean however that I haven’t been building but things take time and exploring and build new things takes even more time. Now however after reassigning the ABC oil cooler and the steering oil cooler it was time to move the engine oil cooler up in front.
Horns and other stuff have to give way but that’s is a minor issue. They will be relocated down under to the left under the steering oil cooler.
OBS - Can see ther's no thumbnails option any more for pictures ..... makes it not so manageable after my opinion.
If I would have known how much time it would take to find the solution for reusing the exist cooler I would have bought a new engine oil cooler with matching fittings and hoses only reusing the pipes attached to the engine block.
I bought some additional original SL230 hoses from a scrapyard to get the fittings and hoses needed. The good thing of using theses hoses are the bends and twist are there so you easily get around corners etc. It does take some time to figure out where the joints shall be and new fittings etc. so I made a template hose before having the final hose done at Hydroscan.
Lot of work but that said I am very pleased with the result – all brackets are solid and no hoses have bends or rubbing on sharp edges. It’s tight and the result is good.
Splitting the two original MB built-in-one cooling systems
Then it was time for the new setup for cooling the supercharger and as said before I decided to split the cooling system in two – engine cooling and supercharger cooling. Why? - the official reason is to keep temperature on the intercooler circuit down to avoid heat soak but it also appealed to my ego – making the change just because I can ….
To proceed with this modification MB World forum is the right place to learn and pick-up all the tricks in the book. A special thanks to NikleinR6 for his very detailed writeup of what he did – a great inspiration for me.
My plan was first to separate the two original MB built-in-one cooling systems by splitting the hoses and keeping engine cooling and supercharging cooling separate – all done with a bunch of used hoses and fittings found at the locale scrapyard but also some new and original MB parts.
First I was assembling it with some brass fittings just to get the right feeling for later and change them out with more “original” parts found at the scrapyard.
The bleed hose from the original intercooler circuit that returns air and some coolant to the original coolant reservoir had to be rerouted to my new reservoir for intercooling. Changing the hose with an original MB part makes that operation very easy and the result looks very professional. Hose A230 501 06 25 changeout with hose A230 501 00 25
Next up was to increase the amount of coolant by adding a new invention; which I hence will call the “ALUSTAR COOLING UNIT” hence “ACU”
It’s a u-bend made in very thick aluminium piping which has two purposes; adding volume to the cooling circuits but also acting as a “heat-stealer” due to the thickness of the unit. The actual form of the piping also makes it suitable for being a wind passive cooling unit. This unit is to be mounted behind the crash bar with half of it sticking down under the bar for cooling.
I got hold of two pieces of aluminium plating which was bend and adjusted to hold the ACU. It’s going to be placed between the radiator and the crash bar with one of the pipes sticking down under the crash bar.
Here it will be cooled and in this position all hoses to-and from the ACU will be optimal.
The ACU and the two brackets in aluminium which is cut-to-fit
The lower part of the ACU sticking under the crash bar
I got some nice fasting clips from Hydroscan – they are solid and are perfect for holding the ACU. Some more cutting and adjustment but all in all it’s fine.
After fasting of the ACU it was time to do the hoses and again the scrapyard showed it’s worth. Finding hoses with the correct bends’ and twist and after some cutting I had a perfect fit.
A good result just hope it will shows to be functional too
