Benzmac! I'm still drooling!! You are such an inspiration!! I wanna be just like you when I grow up! Anyways, I was wondering why you only went to 6,000 RPM on the dyno. By the looks of the torque curve, you're probably making another 30-50 HP at 7k! Or, did you set your rev limiter to 6k?
Oh, and I'm still wondering about your exhaust manifold. Do you have any more info/pics on that? I'm very interested because I'm going to be starting on mine real soon and the more info I can get the better! That must be such a fast car. When will you take 'er to the strip and show up some ricers? Speed-wise, how does this compare to your Kleeman projects? Faster? Later!

Important
Hello Benzmac,
It is me Clinton. I have a '86 190E 2.3-16V turbo as well. Hey I am wondering......I have the Mosselman system and I have been experiencing the accelerator sticking. This is the term I use "sticking" however, the accelerator linkages and cables are fine and are not the problem to the accelerator staying down when at full throttle. I find that after I boost, and I get up to about 5psi. the accelerator then goes at WOT and I cannot fix this problem. The car must then be shut down with the key so I don't drive off a cliff or something. However, I noticed that the boost is not being regulated or that the wastegate is not blowing off at the supposed to 5.5psi setting and I am getting readings as high as 1 bar. I am using an internal wastegate and the fit is very tight between the turbo and exhaust manifold. The vacuum lines from the turbo to the wastegate are pretty cramped.......could this be a reason for the wastegate malfunction? Also, I noticed that on your intake manifold it is a custom job....nice btw. Can I somehow get a hold of one of these? I am suspecting that maybe the boost pressure is so much that it is holding the plate on the Throttle body down so that it cannot close.....and this is telling the car to keep the fuel coming so the car doesn't detonate. This is another theory of mine but I'm not quite sure........Anyway, you are the only other person I know that has a turbocharged 16V and maybe you can help me with my problem........thank you very much. Clinton Davis |

Mbracer,
I'm rebuilding and turbocharging my 16V engine, and I got ARP headstuds for it. ARP doesn't make any specifically for this engine, but I found some that fit. They're for a 2.3L Ford Pinto motor (ARP # 151-4202). Shhhhhh, don't tell anyone I've got Pinto parts in my Benz! But those fit the 4 cylinder 16V head. If the bolts on yours are the same size, then they'll fit. Otherwise, just give ARP a call with the measurements of the bolts and they should be able to hook you up. The ARP Pinto main studs also fit my engine. But, they're a little too long. I had to notch one of the ribs in the oil pan just a bit. Hope this helps!

Benzmac,
I've got a bead on a custom-made copper headgasket. It comes with a special sealant to prevent the typical leaking. How is your headgasket holding up? Are you using the stock one? Did you o-ring the block or head? Would you be interested in a copper gasket if you could get one? Later!

Thanks, I really apreciate the info.
I am sure pinto parts are cheeper than MB parts or did they raise the price when you said they were going into a Benz? Pinto, hum. And they are metric? or std thread? Good luck to every one on theur projects. Watch out... Fast and the Furious III, with 10 to 20 year old benzzzzs. Donnie, Your car has to be doing mid to high 11s 1/4 mile sprints. What does your car weigh? Mine is at about 2650lbs w/M103 now, I still have some more weight to remove. The seats I found weigh 12.5lbs ea. The M104 is a heavier engine, I guess I offset that with the tranny swap that saved me 60 lbs. Auto to manual. Saved/shaved 20 on the fly wheel too. All trunk panels...gone. |

Dan,
I have heard mixed reviews on the copper gaskets. I have an engineer at work that worked for Comp Cams and ZEX. He did cam design and NOS applications and spent most of his time inthe Dyno shop testing. He told me to stick with the steal head gaskets. They hold up better, your less likely to have to constantly retorque the head, and when they blow the problem is big! Keep in mind it's a soft metal that will deform easily. That's why they, initially, seal better. now add heat, vibration, and lead foot. |

I did stud the block and I hope it holds up.
Also, there is a company that makes the studs for the 16v motor. You can get them for 180 shipped to the door with nuts and washers. They are NICE>RACE WARE

Clinton,
I have heard of this with the stock throttle body. There is a seal in there that doesn't like the pressure. Most people just take it out and the problem is solved. To do this, you have to remove the throttle body and completely dissasemble. Good luck. PS, it sounds like your wastegate is not working correctly.

WOW! I'll admit that I don't get to visit here as much as I'd like, and it looks as if some of you are really building some cool toys.
Heck, I was pretty proud of the turbo kit I put on Priests 16 v last year. I only hope he doesn't see Benzmacs car! I was really hoping to put my C36 motor in my 16v racecar and do some crazy mods to it, but current circumstances and other obligations are forcing me to put the car on mothballs (for now anyways). Great job, Benzmac! Now put that car on about a 500 pound diet and stick a cage in it. |

Clinton ... I fought the "sticking throttle" on my supercharged 16 valve for a long time. I bought a new throttle body that did not help, I removed the seal that Benzmac mentioned and nothing helped. It stuck at about 4 psi, reducing the boost to less than 4 psi removed the symptom. I finally solved the problem by replacing the throttle body with a 1989 Mustang 5.0 throttle body when I installed an electronic engine management system. I believe that the stock throttle shaft is too small and it is supported with needle bearings. A small deflection of the shaft will bind the bearings. It looks possible to replace the needle bearings with ball bearings or to replace the throttle body with an after market unit. You need to be careful of the height (the Mustang body is too tall) because the stock injection system cannot be raised because of the hood clearance. I posted a lot on this topic about nine months ago.

Help Cont'
Hello Benzmac and Jim,
OK, so what should I do to solve this??? what should be my first step......sorry guys, I just need help with this......I'm very bummed out that my car is doing this after I dumped $4 thousand into it and you guys are having fun with your cars and I'm still suffering Anyway, I think I might take the TB apart sometime and look at it and also, I may go with an aftermarket TB.....but what will I do with all the factory harnesses and the like, will the aftermarket TB's be ok to use? I know there aren't many offered for 190E's.......Benzmac, On your intake manifold, it looks like the butterfly is moved further up on the manifold. Is this true? or not? If so, do you have any other units for sale? I'm desperate here. What sould I do first? then what? thank you very much Benz Gurus.......fellow turbo 16V. Clinton Davis |

On Priest's car, I sent his TB to Bekkers for enlarging. Ot took them about a month, but it works fine and he is running 6psi of boost right now.
