I think they only did a manual transmission on the very first R129s and then only on the 6 cylinder models, not the V8s and the V12 which would cook the clutch. MB manual shift quality is pretty dismal and I doubt that a manual shift R129 is very desirable.

Quote: Coastline: in fact manual R129's are common in Europe, even on Germany wich has a large percentage of automatic's!
W124 E36's are rare, but about 6 months ago there were at least to W124 E36 T for sale, for a good couple of months! and cheap too, about $10~12.000!!!


jjay911: if your car was a SL 320 there was an easy way to gain 10~20 hp!
replace the original ECU with another from a W140 S320.
also the C36 was automatic only, could give some headaches with the transplant!
Im thinking 3.2 engine swap and bore it out to 3.6 or 3.8 litors and try to get about 320 horse power. Or I could try the v8 but I like the 6. Just cause its different.

cool wheels
jj

great wheels on the sl500 (i've just joined the forum, but was delighted to see an image of the sl on here - I've saved the other pictures that were previously posted on oursl.com)

What manufacturer are the wheels and what size?

Regards

These MB straight sixes seem to respond well to intake tuning. You could start there, and the move on to race cats and a free-er flowing exhaust setup. After that, fine-tune the ECU and add a sprintbooster. You'll notice a very nice difference in engine response and overall power.

If you choose to do serious engine work, then why not just swap the motor for an LS1/LS2? Lighter, more powerful, and pretty much bullet-proof. Plus, you could upgrade your transmission with the manual from the Vette. From a purist perspective, this is terrible. But, from an enthusiast perspective, it will be a cool project.

jjay911: I was reading another forum, and someone found out a a couple of biturbo kits for the 300 /300 24V engines! (M103/104) for sale at an UK dealership! the guy bought one. about £1000.
on the 12V it gives about 310hp!

Manual transmission R129 SL
I am writing from New Zealand. I own a 1994 SL300 that I purschased about two years ago.
The manual transmission is rare in the R129 SL. I believe there are manual transmission SL's in US & Canada as they are left hand drive, produced for the US market and directly imported from Germany.
NZ being right hand drive, some are new direct from Germany made for the right hand drive market and some of the SL's are imported from Japan and with many SL's I have seen in New Zealand and Australia, I have never ever seen a manual transmission SL in the right hand drive production.
Manual transmission performance margin is much greater, specially in 0-60 than automatic and SL with its great performance, its dissapointing that the production of manual is so rare.

TBH, I don't know if the manual transmission versions - only available in any case in the very earliest 129s - were ever made in right-hand drive.

Mercedes manual shift quality is legendary - for being terrible - and reminds me of Greek taxi-drivers in Athens.

The R129 is not a sports car by any stretch of the imagination. It's instead a highly refined GT with amazing build quality. 5 years on from getting my SL55, and 3 years on from selling my R129 SL600, I do miss it. The SL55 and I have never really clicked like the SL600 did, though the 996TT is probably more to blame.

Quote: jjay911: thanks for the reply! I found out just yesterday that US spec 300's were all 24V rated at 228hp!
I was suspicious about the Getrag, because someone told me it was a dogleg, and I knew that the W124's Sportline had a Getrag dogleg, so I assumed the two tranys were the same! didn't know about the LSD, though!!! can it drift, or not really?!

I've read somewhere that AMG built some SL36's but officially denies it!!!
If you ever decide to do it, good luck! engine transplants always get far more difficult than they're supposed to be!!!

on the numbers built, 800 for the world seems kind of short! over here my guess is that most of the 6 cilinder car's were manual! something like 70~80%! and most SL's over here were 6 cilinder, because the 500 costed almost twice as much!
also, Spain, France and Italy were markets with very low percentage of automatic car's in the early to mid nineties. and also where the 500 was much more expensive than the 6 cilinder!

Yes the sl36 amg does exist, i have seen an article somewhere about it, and i have also seen 1 in beirut lebanon about 4 years ago while i was on holiday there.

I wonder if there is a way to retrofit a MB or aftermarket 5 or 6 speed manual, or paddle shift auto to the 12 cylinder. that would make the car so much more fun to drive.

'Sport, the number of SLs with manual tranny imported to the U.S. was not 166. And it wasn't less than 200. It was about 800.

Tell you what. At the risk of appearing to be a "moron", I'll make you this offer. If you can cite a reliable source that shows the number of manual SLs imported to the U.S. was less than 790 or more than 810, I'll PayPal you $100. If you reply here with the source contradicting me, the money is yours. That is a standing offer that does not expire.

I expect we won't be hearing from you again on this subject .

Only one was manufactured by MB, and that was for a Grand Slam tennis championship prize.

Based on the SL 280 developed AMG in 1995, the SL 36 AMG with 3.6-liter inline six-cylinder engine (M 104 E 36) and 200 kW (272 hp). The vehicle was handed over by Helmut Werner , then CEO of Mercedes-Benz AG, to the winner of the Stuttgart
MercedesCup ( Thomas Muster ). This vehicle is a unique piece.
