190E 2.6 into 190E 3.2-24V......

Hey every one. I just wanted to let people know that I'm getting rid of my 2.6L engine in my 190E and putting in a 1995 E320 engine with 50,000K miles on it. It turns out that my 2.6L engine had gap between the pistons and the valve walls making a "pling pling" noise every time it fired (no good). So before I took my car to my mechanic, I took it for a little rally run around my town of Flagstaff Arizona. Fortunately all my suspension was shot after the whole event and now I have to get new shocks front and back (Bilstein Sports) because the old ones were Monroe's all around. The oil light had been on for about 2 weeks but I left it that way to see if I could blow up the engine before I got the new one in (since no one really wants a 2.6L engine with valve gap in it). It didn't work to well, I under estimated the quality of the engine even though it has about 160K miles on it. I've had this car for a little over a year now, and it has treated me well.

With the new engine I'll be running about 220hp stock (217hp is an under statement). I'll have a 300E transmission along with the 3.2-24V to handle the horses. The good thing about this conversion is that I have 3:27's in my diff. so I don't have to upgrade that. This Honda killer is going to have veriable timing, eletronic fuel injection, and some TLC from the boss.

I'm only assuming it will be pretty quick because my mechanic's 190E had the engine in his car first but his car had 3:07's in his diff. and when I test drove it to see if I wanted it in my car, I was passionately involved with the idea. There are other mods I'm doing to my car on my webpage so visit it if you want, but I warn you, I just started working on it so it is sloppy and dumb for now! More updates about this soon!

Very nice! What are W124 fender spacers from Germany?

You should verify the gearing in your diff, the autos came with either a 2.85:1 or 2.87:1 gear ratio, only the 5 speed manual came with a 3.27:1 gear ratio. If your looking straight at the diff cover, look in the right bottom corner, not on the cover but on the diff, there will be a series of numbers followed by the diff gear ratio. You may need to use a wire brush to clean the dirt off of it first.

Unless you know for sure that someone swapped out your diff, it probably has the 2.87:1 gearing. Also, 3.07:1 gear ratios were never used in US spec 190's, although the euro spec 190 16 valve used the 3.07:1 gear ratio instead of the 3.27:1 like in the us.

Good luck with the motor project, its going to be an expensive PITA though. EFI conversions on our cars are very time consuming and complicated. Definately will be nice if you do it.

This is a link to a thread on another forum where I posted pictures of my 3.27:1 LSD diff install (from 87 16 valve)

Why not a C36 engine? Give Rod at Potomac German Auto a call.

Yep, I agree. If your going to spend the $$ and time for EFI you might as well get a higher hp motor like the C36 M104

The W124 Fender spacers from Germany happen to be made by AMG which I bought from OmegaBenz after his recent trip there. They space the fender bolts at the bottom of the front fenders to decrease rubbing on the outer edges of the fender. Its job is to actually push the bottom of fender outwards away from the car so that the tire don't rub on the outside of the fender and bumper.

The reason why i didn't get the C36 motor is because I am only 18 and I need to conserve some of my money for college. My funds needed to go into some other things like cosmetics and eletronics on my car, so I needed to spend it on the various TV's and in-cabin surviellence system. I want my car to be "show & go," not just go. So I hit a happy medium. I just bought brand new AMG 170 style rims 17"x7.5 for $290/rim, they are the real deal.

I'm pretty sure I have the 3:27:1 diff; but I'll look into double checking that and let you know what I find out. I'll have some pictures soon of the conversion and such.

Again, unless someone swapped out your rear diff, or you have a 86-87 16 valve or a manual trans 190E, your rear diff is not 3.27:1.

Rear Diff.

about 2 months ago I went to go pick up my car and when I did, I power sprayed the undercarage of my car so that when ever I work on it, it would be clean. I happend to clean the diff. pretty well and when I did, I checked the gears in it. Inscribed on the right side of the diff. on a little lip was 3.27:1 and I took some photos of it that I will post on my website as soon as I get them in my computer. I also took various pictures of the engine number and other things that I'll post.

Good, step one done. Now the question is...is it a LSD or non-LSD, that is not as easy to tell. Either way, 0-60 times are quicker than the OE 2.87:1 gearing

On a 3900-lbs. car, with 280HP and 287 ft-lb torque @ 5200 RPM, what would be the best diff for low quater-mile runs?

3.27
3.07
2.87

Thanks in advance,

Well, naturally the smallest gears are going to be faster in the get go but slower in top end speed. So you have to give and take. Now, if we could, we'd have two diffs in the rear of our car, small gearing till 3rd gear is over, and flip a switch to change diffs to a taller gear so then you can go fast both of the get go and top end, but we can't do that, some day, but not yet. So..... To make a quicker 1/4 mile time, the smaller gears would be the best bet for you, and from the list you gave me, 3.27:1 would be it. Mercedes made 4.65:1 in the 1960's, but those are hard to come by, and you should re-enforce your sub-frame to take all the torque.

what you would want would be a two speed tail shaft!

Exactly! A two speed tail shaft! Although it would be hard to manufature and fit into the car, it is a very very good idea. OmegaBenz, if I only knew who you were, then I'd go over to your house and start making some plans for this two speed tailshaft. Keep up the good work, hah.

Remember guys....... every time U shift gears/shafts, the car is in neutral for a brief period of time. This seamingly small amount of time affects track times and acceleration times.
