New to the forum after lurking for awhile.
Question- I have 02 s600 with v12 n/a.
Can I add turbos, manifolds, etc from 03 to run on mine?
Or can I swap whole motor from 03 into mine?
What needs to be changed, problems, etc.?
Thanks

Sell yours and buy a turbo model
Seriously it will be much cheaper

Darknight600

I'm not interested in selling it. I'm a mechanic and fabricator
So I don't think it would be cheaper anyway. Plus I plan on upgrading things
Like speed riven billets,etc. to make a fast ride. Still learning all the ins and outs of mercedes.

I had this idea. Like he said it would be cheaper. I did find a supercharger for my 500 used out of a 55 model. I kid you not, used and dirty they still wanted 3000 dollars just to put it in my hand.

You can buy the complete engines with turbos for less from a wrecked donor car. Depending on model you'll probably need the trans too. And the computers, and the programming from a star machine. It's doable , but I'm telling you it's cheaper to sale than buy, even when doing the work yourself. No matter how much you do you will end up at a dealership anyway for the programming

BTW, it's still doable. Remember to start posting pics from day one. It would be a story I would love to follow

I have 2 sets of turbos for sale

Darknight600

Well Ive worked in the automotive field for a while so I have friends in greasy places. I have access to the STARS system for programing and I can get a complete motor for $( lets say a bargain). I just need to let him know asap or its gonna get sold.
I just wondered if I can use the manifolds w/turbos, injectors, intake coolers and whatever else I might need off 03 5.5turbo motor on my N/A?
Im leaning more to swapping complete because I know they run lower compression 9:1 and Im sure other stuff.
I just need to know if the computers will work with each other or can I program mine to work with it? Also if all the wiring, plug ins, and sensors are the same?
Why would I need the trans from the 03?

thanks for the input and help. I will post if I can get all figured out and pull the trigger on the deal. I dont have a money tree but I do have time,know how and dedication.

Not only do you need the motor and trans , but you need the computers , ignition system /key too. Its all connected as part of the anti theft system. You need to basically swap every component of the newer car into the older car .

what the hell, just fabricate some exhaust manifolds and bolt on a set of midsized turbos, put in some bigger injectors, bigger fuel pump, and add a generic ebay intercooler.

If you are a mechanic and a fabricator, this shouldn't be too difficult.

I have this same question but mine involves the motor internal strength.

I know they put in forged rods/pistons and made the cylinder walls thicker.

I'm curious to know the limits of the existing lower components.

I had an old honda prelude that I built a custom manifold and used an old Mitsubishi 14b turbo. 8 pounds of boost with the ecu programming and BAM. That **** was fun. However over 8 pounds it would get dicey.

I know of the turbo 5.5 you can basically throw whatever you want at it, but I'm wondering if I could put 8 to 12 pounds on this existing n/a v12.

I was also curious if I could put in a turbo ecu and reprogram my keyfob for the car or if the current ecu would work with bigger injectors and the current maf and things would magically work. I know some cars will work and some won't.

Another problem is where the heck would I tap the engine for an oil and coolant supply to the turbo(s). I'm not worried about charge pipes as I can cut and weld that up.

Any info you all can assist with would be great.

You would need the transmission because the ttV12 has more torque and the 5 speed transmission has been beefed up to handle it.

Darknight600

I was thinking about mounting aftermarket turbos but I thought the same thing..will the bottom end hold? It made more sense to swap motors. I want to push it beyond simple 10lbs or less.
So basically the anti theft system is like GMs canbus system? Is there a way to turn off the anti theft or maybe do a stand alone system?

thanks

P.s.- if you have smat ace comments then dont waste your time posting. If you dont wanna help or know then so be it.

The factory turbo motor can handle 20-30lbs boost .

I don't know how many pounds boost the na motor can handle before it blow up

LTe

With how many manufacturers build turbo motors, most can handle 25-30 pounds before they blow up. Most N/A motors tend to blow up around 11-12 pounds. That just generalizing though. I had a 1990 bmw 535i that the motor was built like a tank, same with the Nissan 240sx I had, damn things wouldn't blow up until I put about 26 pounds into it. But those vehicles/engines had iron blocks with beefy rods, which the n/a v12 s600 motor does not. I'm sure the rods would go before the cylinder wall though.

As for the transmission, it's the same one as the turbo models, the s600 from 2000 to the current model v12 had the same 722.6 5G-Tronic transmission. They even used them as far back as 1996 in the w140 chassis S class cars. However the 2000 and newer models had electronic shifters where I think the older ones had the shifter that went into the transmission, that's the part I'm not 100% on but your s600 would be fine as would mine.

I was going to turbo mine but I think I'm going to just buy an engine swap for about $5500 bucks. They can be had for cheaper but tend to be stripped down more. Then again I might wait til next year and just trade mine in for a newer 2003-2005 model. Who knows, either way I love the s600.
