Am I correct to assume then that the 3.07 from an 84 300SD will bolt right up to my 85 380SE with no problems? Besides doing the mount, center support and bearing and flex discs, Is there anything else?

Someone said that the axles will need to be swapped if using a diesel diff, I'm not sure of that so let me know what you find. I have an 81 300SD here I'm going to pull the diff on, but haven't gotten to it yet.

I'll grab the parts list but in the pictures you provided, what diff di you put into the W126 with the new rear diff mount cover?

It's the same cover from the 450SE, just really cleaned up. also identical to the one on my SEC originally, only diffence is inside, check my thread in the performance section for more pics.

Its going to take some getting used to, I keep waiting for it to shift into another gear sometimes. figure 3k RPM @ 70mph.

3.07 is what this car should have come with... plus a 5th gear in the trans to accomadate.

116 body, yes.

hmm. While great for takeoff, if you drive above 60mph the 3.46 is going to be wayyyy too much. You pretty much have the same setup I originally have right? euro 500?

I have the 3.46 here from the SLC we parted, I may stick that in the 380SEL at a later date but I wouldnt do it with the 500.

Well I have just bought the 2.65 from Jonatham in Atlanta that he had.

I had thought for ordinary fast driving the 2.82 would be enough, but then again, the AMG 1987 catalogue states the diffs they sold at the time were the "modest" 2.65, the 2.82, 3.06, 3.27 and the "Neck-snapping" 3.46


My reckoning, without having done a dyno test yet, that my stock 2.47 ratio and totally stock engine, with AMG headers and exhaust, and the big Remus 2-in-2-out exhaust (guaranteed 2 hp on the dyno) has boosted the car's HP by 30 hp with no other mods done yet.

That puts it in Euro "kat" territory, the Euro gen. II Kat motor had about 272 hp..



Not into the incredible euro ECE engine, about 300 hp for those, but what I have is worthwhile.

Stepping on it hard from 90 mph is as smooth as pouring water, past 135 mph.

Absolutely great.

If it scrubs a few mph off the top end I don't care, as I had it up to 152 once and the accellerator wasn't even floored. A mere 4800 rpm or so was
spinning at 145 mph.

heh yeah Jim, I havent hit the top end limit yet, but with my old diff, It was 4,000RPM with the speedo showing 140, but the speedo used to read under the actual speed, it was probably closer to 160. damn it was loud!
