E320 CDi mod
You might have V6-engine.
It has piezo-injectors.
There is no need to change, they are very good and fast.
They are good for ++300hp.
Turbo and DPF are the problems.
They limited the power under 300.
These AMG-injectors, spoken here are only for straight cyl. engines.
Starting in 2005 MB equipped all diesels, inline and V-6, with piezo injectors, the inline engines with slightly lower injection pressures than the V-6, but still in the 20,000+ P.S.I. region.
The straight 6 engine cars (2005 & 2006) have no DPF at all, only a single catalytic converter which is not monitored (no wires and sensors after the filter) so it is possible to cut it out and increase the flow without triggering check engine lights.
From your message I take it that my car can use the AMG injectors and nozzles?
Hollow-out of the convertor may be the only choice.

You can remove the cat and put in a straight pipe, like I did and also Tuikku
This way you make the EGT and EGP run also a bit lower.

Yes, they fit "plug and play".
And they also works fine with the stock program, idling also.
Power increasing is about 30% with no more mods.
That is ok also for the original charger.
Although, reprogramming is advisable, hope you find someone there.
There could be two cat in there, at least here, in Europe are.

After the warranty expires, of course.

Another question. If the EGR valve is blocked off like yours where does the exhaust go? Straight back to the system? Presumably it is not under a lot of pressure.
From Tuikku's page 3 photos I can only see one cat lying horizontally (emptied by him) after the turbo. Mine goes down obligely and lies future down to the floor pan level. So it is possible that the E320 CDi has two instead of one cat. The only way to tell is to remove the large air box which blocks the view totally.

Gaiexeīs engine room is quite similar as mine, but much much cleaner, I see.
There is nothing original in that downpipe and exhaust pipe any more.
No check engine lights.
Engine doesnīt know anything about that swap.
Hargar, EGR valve donīt move any more, when it is blocked off from program.
It is shut all the time.
Program asks "clean" air all the time.
All exhausts go straight through the charger.
EGR could leak a bit, but that is not a big harm.
Although it must be "in shape", or -> limp mode.
That is in electrical systems, like your car.
In vacuum conrolled systems, like Gaiex car, it doesnīt matter.
30% power increase (according to Mr Tuikku) is not too shabby at all.


460 each one, this in a Bosch resseler, at MB dealer I can imagine...
This injectors they don't repair them, only factory or bigger bosch centers do it.
If they where a "normal" repaired injector it would cost +-100 each, but they are selling only news!

hi Bjornar,
those injectors cost 355 euro each (new from mercedes)

This is from Steve Krabbenborg. What he can't get you isn't worth getting.

+-100 each one for reconditioned should do the trick, but I need to find someone that sell them!

Then you have to do some modifications to your injector that they work like AMG injector or you only change nozzle and then your injector is 10-15% better.
"Tuikku" knows more about these operaations and he knows the guy who makes "AMG" injectors.
I hope somebody understands what I mean..

So, to keep my mind free of future problems I will go with complete AMG injectors.
Bosch guys told me the AMG injectors have injection times and injection angle diferente from my stock ones.
About the timing I know that can be tunned with electronics, but what about the angle, its bad or no problem with it?

But normally the second cat get stuck and that make higher EGT and EGB.
