Hey everyone. In the near future I plan on putting a turbo on my XF. I was going to see if any of y'all could help me out on the engine in the car. I know it's a 3.2 Mercedes engine but what are the weak points? How much power are the heads, block, tranny ect. Good upto? Any input would be very much appreciated!!

 

Jason if you only knew what you are asking for.... Look up the BEGI turbo build... you should have all your questions answered in about 2 weeks.

 

Hmm.. about the same answer he got in his other thread with this question..

 

yeah, Ill check everything out. Im still trying to figure out all the controls on the forum so yall gotta bare with me haha, but I just posted it twice in 2 different sections of the forum. Im still the newbie!

 

Purge those evil turbo thoughts grasshopper, think V8 swap or just sell the N/A and pick up an SRT6.

 

Thats what Im trying to figure out tho, whats the big "no no" with a turbo on my NA XF? Why is it so bad? Besides money lol

 

I do understand that money is an issue as well but why don't people do it? are the motors weak after a certain amount of power? Hard to get them tuned? I want to know all the reasons why I shouldn't turbo mine and why no one else does!!!

 

Okay I'll try to make this clearer than the other thread.. Click your mouse on the BEGi turbo in my signature below..

 

its not "bad", its just that pretty much *nobody, including a company that does this for a living) has gotten one to work


*there might be one out there but the undertaking was monumental

 

so my ? to you is why didnt you just buy the SRT6 in the 1st place if you wanted more power !!!! I like mine the way it is !!!!!

 

The ECU work is the complicating factor. Not necessarily tuning, eurocharged can deal with that, but using an ECU to remain factory or smog certified. You need a base ground on the ECU and the NA ECU isn't it.

You could go piggyback or full aftermarket ECU but you're looking at the big bucks and a huge headache with wiring. It will never pass smog either.

Do your research, and just sit tight for a bit.

 

I read from page 1-6 about the Begi turbo section and everyone seemed excited about everything when it came to turboing the XF. I bought mine at a dealership. There was mine and an srt6 right beside it. I wanted the srt6 but i enjoy driving a manual too much so i decided i would sacrifice some of the power so i could have a manual lol. I still didnt exactly read or quite understand why the turbo kits dont work exactly. I know im being a very big headache and i do apologize about that everyone. I understand the ECU problem. I saw a few places saying you would need the srt6 ecu or (e32 maybe) i forgot the other one haha, but I just dont understand that If have all the money I need and i take my time with everything and get everything done right why the kit wouldnt "work" like I said I know Im being a headache and Im sorry everyone

 

simple " THERE IS NO KIT ! "
Maybe in 2 weeks ( keep checking the turbo thread, or go ahead and sign up for it since you are an optomist )

 

I see that now..... but do you think I could get like the turbo manifold custom made? and just piece together my own kit and get it professionally done?

 

I am not qualified to comment further on this thread, anyone want to take the ball ?
MrMiata perhaps ?

 

Been done already.. there is a thread on it too.. Tell you what.. call every speed tune shop you know and see if they can make the electronics work with a turbo on this car. You resolve that.. your 90% done with your turbo install. Begi's isn't working because they aren't working on it. Bit off more than they can chew and it's a mexican standoff to see who folds first.. then they can keep the money and claim "we" pulled out..

Oh... and I'd have that tuner outline and specify so you don't end up with a Begi situation.. "KNOW' they know what they are talking about.

Edit one more time.. "Turbo Manifold".. we can't even fit a decent set of headers in the car.. If you know anything about cars.. that answers that question.

Oh and I can honestly say at this time.. Money is not an object other than what I'd consider spending on the car.. But there is no way some one gets my car for two years and counting.

 

No worries were a community for helping other owners. And I understand completely on wanting the manual over some power I could add later.

If you threw a turbo together on your car right now, it will not run right or even close to it, plain and simple. If you threw one on and had a 3.2 AMG ECU coded to your specific electronics then you would be close and the ECU would have the ability to adjust based on boost (MAP readings). It may not adjust enough and there are still other things to work out like the SC clutch pulley, wiring for MAP and IAT... but you would be close. It would be much easier to tune from that point then on the NA ECU which will not read boost or know what to do with it.

Now the ECU work has all to do with the relationship between Mercedes modules on your specific vehicle. This has not been done and it is not from lack of attempt. Big names like Brabus couldn't even get an M113 E50 automatic to work properly in our chassis. Research HDDP and see how much he tried and he couldn't get an SRT 6-speed to work....

Also don't look at this as "adding a turbo", look at it as putting in a different engine. Research that on Mercedes and you'll see exactly what I'm talking about. It can be done but it's not a walk in the park.

 

Thanks everyone. Im glad Im getting this much feedback but basically the main concern would be the ECU and getting it tuned and accounted for properly? Or am I missing something else as well?

 

Your on the right track now.. STS makes a "kit" rear mount where it pretty much has to go..and has been installed on a Crossfire before.. to dead end at ECU interface.

User BJames is off on a Turbo Tangent.. and looks promising.. he knows what is involved and undertook the project.

 

Pretty much, just understand Mercedes ECU's are not plug and play, and there are very few that will actually touch them let alone code it to your car. It took me 8 months of research and about 11 ECU's to figure out what to do with them for each certain scenario... and that's fast if you research others with this kind of stuff.


^^^ OP, this is why I'm saying sit tight.
