Mercedes-Benz M103 Turbo Install Part 3 | First Start

[@jorn1409]

Bringing back a 1992 300CE to life again myself, you're an inspiration. The joy you put into it with your family and friends is all I needed to tackle this project.

[@AutoAfflicted]

Rad! The C124 is such a timeless coupe - those 90s wiring harness on the M104 for though - can be a nightmare if not replaced due to the biodegradable wires

[@jorn1409]

@@AutoAfflicted Fortunately the 1992 coupe models were spared that nightmare. But plenty of other challenges, to keep me awake at night.

[@AutoAfflicted]

Nice! I didn’t know they avoided the harness debacle

[@jeffbender5055]

The excitement was real when it started

[@AutoAfflicted]

Yes! Always exciting to know what sounds it makes

[@Jaostemannen]

I just found this channel and I am suprised that you do not have a 100k of subs or something because this is quality! Very interesting video with good sound and picture. There is this abandoned 300ce M103 where I live. Now I want to buy It xD

[@AutoAfflicted]

🙏🏼 Hoping that the channel builds ! Been going at it only 6 months. You should get that 300ce! Such great cars, unless it’s rusted out

[@Jaostemannen]

@@AutoAfflicted I have a Mitsubishi Triton and I have been looking at Delicia, I see you have made video of the Delicia, so I have been late nights rust welding before xD

[@AutoAfflicted]

The Delica was a very fun vehicle to review. I could definitely see having one of those in the stable of vehicles

[@Jaostemannen]

@@AutoAfflicted Very fun and very realiable. But they rust!

I plan on doing the same to my W201, it caught me off guard when I heard Salt Lake City, maybe I’ll see yours some day!

[@AutoAfflicted]

Yes! If you’re local follow the Utah Benz club on FB and insta - we’ll Link up

[@daveynino5141]

fantastic !!!!!! love the sound wowzer ..... great job !!!just epic!!!

[@AutoAfflicted]

Thank you man! The sound is pretty amazing. It’s gonna get a little bit more refined as the rest of the exhaust comes in the place. Right now it’s just the downpipe

[@boostedbenz]

Just make sure to plan to take that oil pan off. I did it the same way. Was super careful and still ended up with lots of shavings in the oil pickup

[@AutoAfflicted]

Thanks for the heads up on that

[@rafaelestrada-gl2sh]

I’m having difficulty getting the 4”elbow get onto the 4.5” intake throttle body. What’s the trick? Again thanks for sharing! Be blessed!

[@AutoAfflicted]

I used a small screwdriver to pry it over the lip and then worked the driver around till it was on. You could use a heat gun to soften the hose a little for more stretch

[@rafaelestrada-gl2sh]

I thought about it but I didn’t think it would work because it would be heat resistant. I’ll try it. Thanks so much again!

[@jarmominkkinen9409]

Hau dou you fix The extra fuel wen The Boost come???

[@AutoAfflicted]

You can turn up fuel pressure at the EHA VALVE

[@taylorbushnell5838]

Love the build and am planning on replicating your build. I think I heard you adjusted idle slightly, EHA valve a quarter turn and change plug gaps to .28, but did you have to do anything with timing?

[@AutoAfflicted]

🙏🏼 No timing adjustment but I believe there could be a benefit. The plugs gapped to .028… everything else correct

[@taylorbushnell5838]

@@AutoAfflicted Oh, yes 0.028! Haha. Thanks for your reply. I’m only chasing more power down low as it’s a 300SE I’ll just be cruising. Would you recommend I get a smaller turbo than what you ordered? How is the turbo lag with yours?

[@AutoAfflicted]

Always great cruising with some extra power … down low

[@zeek050]

Sweet video! Im located in pleasant grove. Hoping to do this to mine soon !

[@AutoAfflicted]

I highly recommend it! I am in process of replacing my head gasket, def worth considering a MLS gasket for strength… I work on a break what you have first philosophy but going the extra mile always yields the best results

[@zeek050]

@@AutoAfflicted I'm having a little bit of oil burn from what i believe to be the valve seals so i was planning on getting the head redone. MLS gasket and turbo headbolts are definitely on the list! Do you have any content on driving it?

[@AutoAfflicted]

Sounds like you’re on the right track. I didn’t get around to making any driving content, I wanted a big reveal with my new wheels that are still not finished 😑 there are a couple clips in my “shorts” kzbin.info-lfIXJ51kAU?si=J6N_NtSXVj3CApI9

[@zeek050]

Have you noticed decrease or increase in MPGS?

[@AutoAfflicted]

I haven’t noticed, I bet it’s better on gas just cruising but usually I’m on boost eat up all the fuel

[@bills8450]

Thanks for the great video series on this! Very helpful. Putting together a very similar kit now. Any chance you remember what 90* fitting you got for connecting the oil feed line to the turbo?

[@AutoAfflicted]

Looks like I failed to include the link to that particular piece. I did find it on Amazon by searching turbo feed line and then just using the one with the appropriate length and the 90° bend on the fitting.

[@markusholmqvist2735]

Great! im so excited to do this on my own 300ce

[@markusholmqvist2735]

are you gonna do a part 5 after the results of tuning this?

[@AutoAfflicted]

Yes! Do it ! Boost your coupe!

[@AutoAfflicted]

For sure there will be apart five. I also realize I need to detail how the wastegate and blow off valve are set up as far as vacuum and boost hoses etc.

[@hanenkamm1979]

Awesome! I have an 89, W201 2.6L w/4sp automatic. In researching modern engine, transplants, I’ve come across many of these, turbo upgrades. I’ve owned this car for 21 years and maintained it well. It has perfect compression, I’ve done the chain and the valve seals, but that’s about it. It’s such a bulletproof engine, I would love to do, this modification with a 5Speed manual transmission swap, and enjoy. Is there a company that does a full bolt-on kit, exhaust included? I would love to fit that in our cooler behind a DTM/EVO-2 body kit.

[@AutoAfflicted]

I don’t know of anyone with a full bolt on kit. That was the impetus behind this series. There are companies like Turbo Bandits and Kangaroos team, hedgehog racing that all make a bunch of great bolt on pieces for turbo application and offers manual swap kits

[@thetrenchplatediaries]

Awesome work AG… 🤘🏽✊🏽

[@timdowntown8746]

Loving the build so far, I plan on doing something similar to my 300ge with a m103. What are you doing about tuning and what type of trans is in the car?

[@AutoAfflicted]

Tuning - maybe gap my spark plugs…but nothing more. Idk what trans, the stock one tho

[@AutoAfflicted]

Turns out I upped the fuel pressure using the EHA valve and then adjust the air fuel mix using the idle adjustment … also gapped plugs to .028

[@rafaelestrada-gl2sh]

Did you add a dump pipe on the wastegate? Free flowing? Thnx

[@AutoAfflicted]

Straight to atmosphere 🫣

[@MrDevon29]

Hey Ali can you help with turbo kit the ones on eBay us saying it doesn’t match

[@AutoAfflicted]

This is the link to the exact kit I purchased. If ebay is saying it “won’t fit” your car, that is normal, it would only say it fits a vehicle with existing turbo - www.ebay.com/itm/373651078784?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=bqoci8ncrts&sssrc=4429486&ssuid=Mbl7PvMNRTm&var=&widget_ver=artemis&media=COPY

[@ModifiedMotors4U]

What oil did you use ? I’m want to go thicker for heat protection

[@AutoAfflicted]

Yes def go full synthetic and thicker. Depends on your climate also, I think 0W40 but not positive

[@ModifiedMotors4U]

did you have any issues mounting the turbo drain (sump side) with it being angled down slightly, im doing my m102 and will try it but not sure if oil can back up in it.

[@AutoAfflicted]

I haven’t had any issues - the angle is minimal, certainly a little oil could pool in the hose when the engine isn’t running. But the amount of oil that would sit there is likely minimal… not even an fluid ounce.

[@ModifiedMotors4U]

@@AutoAfflicted sweet, done line same place so hopefully it works for me on my m102, greetings from uk, thanks for the reply 👌🏼

Indeed! I hope it works, always happy to help

[@RuggedBrotha]

HEEEEEEEYY! If tiy put a turbo on thesse engines, will it kill the smoke certification??

[@AutoAfflicted]

Not if it’s properly tuned and has adequate exhaust system

[@robertpotoschi8878]

The vaccum for the servo brake is still on the intake manifold, or do you get vaccum from other place? Cause i think with turbo , the intake manifold is presurized and will not make vacuum for brakes. Or it is still makes vacuum?

[@AutoAfflicted]

Still makes vacuum, I’ve not messed with any of that aspect - brakes and ABS fully functional.. I don’t brake and boost simultaneously… unless I’m getting ready to gap someone off the line

The hose does stretch to fit over the throttle body, I used a thin flathead screw driver as a lever

[@salehfiras943]

The video is very very good still I wold've liked a bit more info on the fine tuning of the ke jetronic from the eha and O2 mixture to see how well it runs! Beside this great video

[@AutoAfflicted]

Thank you🙏🏼 I did detail a little bit of the fuel management tuning at the end of the Dino video. Essentially I turned up the EHa valve 1/4 turn and adjusted the O2 mixture. I also reduce the gap in my spark plugs to .028

[@salehfiras943]

@@AutoAfflicted I watched it I think +70hp/80hp compared to stock is worth it

[@AutoAfflicted]

I think the power gains and new character of the car is worth it. Also I see consistent 8-9psi under load on the street and have damp conditions 0-60 times of 6sec with 1/4 mile in 14sec so I think the power a little higher that recorded on the dyno @ 7psi . They have a mobile dyno that can be adjusted to add resistance.. I’d like to test on that one @ 8-9psi

[@rafaelestrada-gl2sh]

Should the spring for waste gate the same as blow off valve? E.g. 8psi or it doesn’t matter? Thank you

[@AutoAfflicted]

The spring rates do need to be somewhat balanced, if your BOV spring is to strong it won’t open

[@farukmusa7577]

Hi..you did a wonderful job.i have a w202 please how psi will you suggest.. from Nigeria

[@AutoAfflicted]

Greetings! If you have the M104 engine, I would stay around 7-9psi. More than 9 psi you risk reliability

[@TwinSOLid438]

Did you upgrade the injectors if so which did you go with my son has a 89 300ce

[@AutoAfflicted]

I did not upgrade the injectors, I added fuel pressure via the EHA valve and fueling seemed to be fine during dyno testing - check out that video

[@TwinSOLid438]

Will do thx

[@kiqnkf]

Drilling the oil return hole and having oil run out scares me. I always return the oil above the oil level.

[@AutoAfflicted]

That’s the highest location on the pan - I think it ran out more due to angle of car

[@kiqnkf]

@@AutoAfflicted It looks like it works fine- and that's all that matters.

Thanks a lot 👍🏻

[@hyperstguy]

Congratulations on your build and video. I just wanted to comment and maybe help other owners by informing them about the risks of turbo charging a Bosch CIS K/E Jetronic system. Without the proper ECU and sensors that come with EFI, you run a massive risk of detonation and all your money and hard work you invested goes to waste when you blow that piston out the sidewall. The only adjustment you have on a K jetronic system is the EHA valve and air flow meter. Not to mention all the things that can break due to its complexity and age...

[@AutoAfflicted]

I wouldn’t call it a massive risk. The EHA valve and air flow meter allow enough adjustment for this basic low boost setup. It’s runs great and produced 270 WHP @ 7 psi.

[@martinj9251]

Just a thought I race a turbo drag bike, are you bracing the Turbo to the engine or close? AS you may possibly end up with a cracked manifold if not!

[@AutoAfflicted]

Good point - def something to consider. I didn’t plan to but couldn’t hurt - that turbo is very heavy

[@martinj9251]

@@AutoAfflicted I would highly recommend, it's the weight of the turbo and vibration over a period of time 👍🇬🇧

@@AutoAfflicted iam talking about money not time

Understood- you can just multiply time x hourly rate of your mechanic … some mechanics will give you a flat rate, some would refuse to install - if you’re just referring to parts cost … about $2500 to 3k

@@AutoAfflicted My Turbo kit landed today!!! 🏁🏁🇬🇧

[@AutoAfflicted]

Nice! Something I’ve learned recently is that you need to adjust your spark plug gap specific to turbo cars. Standard plug gap is too large and the added air being forced in essentially blows out the spark. This feels like reduced performance mid throttle and increased power when you lift throttle slightly. .032 - .028 gap is recommended for boost under 15 psi .. reducing the gap has made this issue noticeably less. Currently I’m at .032 but plan to go down to .028 as I’m getting a little spark “blow out” it seems

What about engine management?

[@AutoAfflicted]

Research shows that for low boost eight psi set up like this, the stock CIS system can manage. It is important to reduce the gap on the standard spark plugs to account for the additional air being forced by the turbo

[@davidsalem4526]

Excellent job! I had the same question at the start. The air-fuel meter is calibrated for atmospheric air pressure. However good on you! You did it!

[@AutoAfflicted]

Thank you 🙏🏼 I guess the CIS system is just simple enough to adjust to whatever you throw at it within reason. Certainly took a lot of research and have learned quite a few things in the last week or two to get it dialed in - I put up a “short” yesterday showing a pull at five psi. today I’m gonna put in the boost controller and turn it up to eight
