- Опубликовано: 8 сен 2024
- In this episode of Auto Afflicted. We drop by Adrenaline service and dyno ( @ADRENALINEDYNO ) to quantify how much power the Mercedes-Benz M103 Turbo is making. We take a few pulls on the dyno and I explain some of the key tuning elements that get the turbo running smooth with the stock K-jet fuel management.

People talk about 2jz but this was original 2jz that many companies including Toyota used as blueprint to design their inline engines
So true! It is a Benz product after all 🇩🇪 pinnacle products
M104 is a kinda apple to apple comparison to 2JZ. A descendent to the M103 in this C124. Dual cam, variable valve timing, aluminum head and iron body. But M104 has an infamous head gasket issue that 2JZ doesn’t have. Except that those m103/104 are very good engines.
Dropping m119 into c124 is one of my wishlist. Turbo is also a good idea!
That’s interesting- I know nothing about 2jz till now
Yes a M119 would be a nice move.. and then add turbo! ❤️
Currently working on my W201 m103 project. Your content is really helpful. Thinking of turbocharging my engine too
That’s awesome! The M103 is such a great engine. My whole goal with this video series was to demystify the process
Did it have the m103 originally?
@@paavorahkonen7634 originally 1.8 m102 4 speed manual. I have the m103 3.0L (132kw) engine with 5 speed gearbox and 2.6 subframe with big diff and beefier driveshafts, currently painting and restoring them. MTS coilovers waiting on the shelf, swapping all the suspension parts when the underbody is recoated.
Really cool to see your build workout, I’m working on a simmilar build but I’ve got custom made intake that supports modem efi with fuel rail and Bosch ev12 injectors. Hopefully with my increased fueling abilities I could get some quicker pickup and some better hp numbers (easier tuning because I’m going to use a standalone ecu too)
I’m interested to hear the results, EFI def increases potential and tune ability
Just got caught up on the series today. Can’t wait to see the next one. Hopefully a drive
Yes definitely a drive! We’re in the throws of winter here in utah ❄️, waiting on some clear days
a pretty healthy number for a bone stock KE-jet running system.
I’m pretty happy with the outcome
Extremely valuable information,, 👌🏁🇬🇧
Stuff you learn after you’ve installed the turbo and hope it wasn’t a mistake 🤔🤣🇩🇪🌬💰
bros good job on the videos super entertaining and informative
🙏🏼 thx! Always aiming to bring information and entertainment to the projects, thx for checking it out
Great work man! Huge respect for keeping the CIS to do the injection. Any plans on going full EFI?
🙏🏼 I don’t plan to go EFI. The turbo totally changed the character of the car and it’s even more fun than before - now to fix the interior and fit some nice 3 piece Brabus Monos
@@AutoAfflicted If you get rid of those AMG Monos - Let me know!
For sure! Do you want them refinished or as is - they either need to be re chromed or stripped and painted
@@AutoAfflicted I was planning to strip and repaint them.
By the way, this has been such a great series. I picked up my 300CE M103 back in late 2020. This has given me hope on how to bump up the horses, and you made it seamless for people such as myself who do not have the mechanical experience... Thank you!
Thx Scott🙏🏼 I’ve been very pleased with the end result. Turbo is the way and the hardest part is owning the correct tools, installing as you’ve seen is not so difficult
Awesome!
Nice to get some results, even if at only 7psi.. on the street with rear world resistance I’m seeing 8-9psi
@@AutoAfflicted i have no doubt that even at 7 psi it would be waaaay more fun to drive in standard form.
Yea! The turbo totally changes the character of the car
As a dyno operator, watching them run that car at high 13s to low 14 afr while under boost was absolutely horrible. I'll shut down a run and talk to customer as soon as I hit 13
I'm impressed, congrats!
How about the gearbox? The gear changes are still ok in full boost?
Also, please post a looong driving video if possible.
The gear changes are great actually! I will definitely be doing a driving review soon
We need a m104 series
Basically the same but with the added advantages of the M104 - I do have my eye on 300ce 24valve 🤔
Just watched the series and it was great! This surprisingly doesn't seem that difficult (I may be wrong), would you consider this process hard or reasonable for a diyer?
This was all pretty basic bolt on stuff. I would consider it really fairly easy for someone who is mechanically inclined. The hardest part I’ve already done for you, which was finding the exact parts and the little bits of tuning that it requires
Awesome vid mate, I have the same model and am In the process of getting the pieces together to blow some wind up it, instead of me asking a million questions, is there a place you get your information on tuning? How to control on boost enrichment?
So my turbo kit came with a manual boost controller and 3 springs .. you can check video # 1 for the parts list and links to everything I’ve bought - I’ve set that up with the 2 port external wastegate to have 8-9psi on the street … on the dyno I only pulled 7 due to lack of load resistance . The only tuning I did to it beyond that, I explained at the end of this video. In the description of this video are links to gapping plugs, adjusting the idle valve and the eha valve. If you have more questions feel free to ask - that what I’m here for 🤛🏽
Hi great work, I’ve finished my install. Very similar to yours, I’ve done some preliminary tuning with the eha, A/F ratio is good on full boost around 12.5-13 but pretty Rich around 10 at crusing, did you have a similar scenario with yours?
Thanks
I was def running a little rich cruising
Next video please...
I feel the same way! I’m buried in snow and all I want to do is capture the turbo Benz out in the wild
Great stuff. Just finishing turbo install on my uk 2.0 190e (w201). What kind of afrs are you hitting on full throttle?
That sounds like fun! Currently I’m running a narrow band, so exact afrs I can’t report on
Did you use the original bosch k-jetronic? If yes, how is the adjustment?
Kind regarts from germany
I did use the original Kjet - watch the end of this episode- I explain the adjustments. Gap Spark plug to .028 gap. Eha - turned up 1/4 turn to increase fuel pressure . Then adjust air / idle valve to get you ideal air fuel mixture, you’ll need some sort of air fuel ratio tool for that
Very, very impressive ! thats otherwise stock right ? Im working on a 2.6 version, but I got the dbilas cam to compensate the displacement difference ;)
ya 8psi to keep it safe with CIS please ) dont forget the lack of a knock sensor, you lean out .. its gonna ping
btw, are you on the forums ?
Yes stock. I’m not active on forums but have combed through a few to gather the knowledge for this build
@@AutoAfflicted Impressive indeed, these sure are good motors. I love mine, 33yo and runs like its new
yep, recall catching that during the video, but figured maybe I would catch you around there )
did you use the standard ignition set up ? and no adjustments to ignition timing ?
Correct. None of my research showed the need to retard or advance timing for this set up
@@AutoAfflictedwow okay that’s good news thank you
@fintrenery2439 colder sparks plugs are recommended .. I failed to note that
Got any sources where I can learn more about CIS tuning?
This guy covers a lot of different topics for M103 and CIS. There is also a Facebook group for CIS - ruclips.net/video/1UQjX83S8iA/видео.htmlsi=5xzjd_mH8xQocwti
Soooo .. are you using the "fuel quality " knob to pull timing out ? its just a heap of resistors i always dreamed about putting a boost triggered relay on it and pulling timing just on boost ... a water meth kit i imagine would be another great tool to raise the possibilities of getting up over 10 psi
I increased the fuel pressure at the AHE valve by 1/4 turn and gapped the plugs .028, the adjust the Air fuel mix with the idle adjustment. I believe I can go over 10psi with stock kjet fuel management
@@AutoAfflicted i was talking about ignition timing do you have the knob attached to the ignition module ? i believe there is up to 5 degrees that can be taken out with that witch will be handy for you making boost so early you are at high risk of getting knocky .. ignition timing and knock is much more of issue at 3000 rpm where your little turbo is making plenty of boost .. keep at it great content
My car does not have the fuel quality knob. I found some research that showed Turbo Technics recommend setting S or 1 which retarded the timing 39-43 @ 3200rpm which is standard for premium gas M103. You could def achieve the timing on boost you desire with a stand alone .. thanks for the input and checking it out! Always looking to improve this and spread the knowledge
Will you do a video with a test drive ?
Yes, definitely. It’s winter here so I’m waiting for a dry sunny day
love the build, which ECU you were running?
Thank you! Stock ecu actually
@@AutoAfflicted which ECU is it?
@@magaricklasi6830 factory CIS
Have you tried playing with the r17 plug to richen the mixture and up the boost?
R17 Plug
1 Stock tune
2 Lean whole mixture
3 richen whole Mixture
4 richen warm up
5 richen warm up & acceleration
6 richen acceleration & remap
7 richen Warm up & accel & remap
ruclips.net/video/ti166sTbxAw/видео.html&ab_channel=FixyourMercedes
I was unaware or this R17 switch. I’ll check it out 🙏🏼
Nice project , how many psi can the cis take ?
Thanks you! I’ve been told 8 psi is about max the CIS can handle - I’m getting 9psi on the street now with no issues.. will try for 10psi
how do you do to increse the fuel to lower the AFR??
You can increase fuel pressure by adjusting the EHA valve - in the description are links to videos that show how to adjust the fueling
Thes Engine are good four 12 psi!!
In may try ramping up the boost later this spring -
What gearbox have you got on the turbo benz? Is it manual?
Just stock gearbox. I’ve consider a manual swap but the cost is fairly high
@@AutoAfflicted lucky you. It’s so hard to source a manual gearbox here in Australian. Ive got an 87 300e. Would love to turbo and manual swap her. I’m looking for to see how your project goes. Thanks for documenting the process. It’s worth it’s weight in gold.
🙏🏼 very happy with the results . I wish you luck finding a manual trans to swap
Sir, if the M102 bolt on turbo is there any side effects?
I don’t have any experience with the m102 but I have seen them boosted. I would imagine the process/tuning would be similar… the engine compression may need to be lowered
ok thank you sir..i think i want to do it on my 230e
Check with kangaroos team website to see if they make a manifold
Ok sir
Have MB 126 300Se want thes kit on May 126.Sade i most have have better Esu The mekanik on The orginal are bad..r
Could probably still turbo with your CIS fuel management
I gonno get the Efi Vems mauby MaxxEcu. May gol are abaut 300hp on The weels...Hau obaut The AUT Can it handel The power????
Way so lo Boost??? I tink 12 psi well go you handel ore wath dou you tink!? Turbo Bandit in Sweden he have over 1000hp on The weels ai tink..Weery sad he is nith wit oss no more R.I.P....
RIP Roman of turbo bandit - I stayed with 9psi to for lower stress on engine and so I didn’t have to do EFI or other stand alone management . Turbo bandit pushed a lot of psi but they had fully built bottom and top end engines
