Hello everyone Now my car is into the 3rd week of leaky sump buggers. I have got 2 w124 in my stables for the donor operation. Donor 1. High miler over 150k 300 TE with sls and ASD diff 1991 Donor 2. Low Miler under 100k 300 E with cruise control 1986 My brain is saying take the take the full running gear out of donor 2. Also whilst at this stage can I change from an auto to a manual? Normal manual box or Getrag?? All info greatly appreciated. EDIT: If anyone has got any Getrag or manual box plus pedal box assemblie and manual ancillaries gimme a shout if you looking to part company for some form exchange ears to the street people

ive owned a 2.6 with a non getrag five speed manual box for a couple of years, i found there's nothing wrong with the box itself but the gear change is very long in between each change of gear, from what ive read on the forum the getrag box is the one to go for, also if i were doing the engine swap id use the low mileage 300e engine then have the cylinder head off and have it polished, ported, valves ground in, plus new valve stem guides and seals, i had my 2.6 cylinder head done and you definitely can notice the difference, good luck any way |

Thanks for the input iggy I just wanted to ask would it be really worth the extra effort to take the head off on such a low miler? It hasnt even turned over 90k. I was gonna do a compression test, seehow it was running , then just do a straight swap minus the gear box if i was keeping auto but if I was going manual i would need to source all those extra bits and it would take me longer till i have gathered it all up.

yeah i know what you mean it cost me £600 to have the head work done so best just to leave it and get the engine swap done, i supose the easy way is to fit the 3 litre engine a auto box then you can use the car and sort out any small problems while giving your self time to get all the bits needed to change it to manual gear box, unless you have another car to use, |

I let a guy at work drive my donor 300E and he floored it and broke the throttle cable so that is a set back temporarily at the moment, but still able to move it at snails pace, the thing is my 2.6 is just sat collecting dust and leaking oil at the same time before I decide what to do. I am just thinking its going to be complicated and time consuming for a manual especially a getrag conversion as the parts would be a nightmare to source. Maybe ill go kenny style and get a auto 3.0 Edited by PARI, Sat Sep 17, 2011 6:32 pm.

i love my auto box it works great after having the filter and fluid changed it used to be a bit sluggish before but now it changes down a gear really easy with out using kick down, the only thing that lets it down for me is at 70 mph its doing well over 3000 rpm i wish it was a 5 speed auto but ive heard the 5 speed auto box can be agro |

same here mate, its shame but from personal experience 300E 24v had the said 5speed box, and it ended uup knackered and costing a fortune to repair and never returned to its former self. the initial problem we had with the 5speed was it it refused to move from 2nd to 3rd all of a sudden. I mean i didnt know the difference until the oil cooler blew up that i knew it was a 5speed rather than 4 speed |

the 3.0 does work very well with an autobox, the torque means there is decent power across the rev range. But hold it low with the shifter and it can be very rowdy indeed ![]() By far the easiest is to stick with your auto. I cant say I dont occasionally wish for a manual but living in london its far more often that I am glad of the auto. However I do have access to the 2.6 manual for kicks too and its certainly more agressive. I am one of the minority who actually like the standard mb manual box. I like to feel the mechanics of what is happening, I like to feel I am moving a rod thats shiting some linkages that twist on some shafts that push around some gears ![]() |

not sure mate, the urge for me comes and goes. Some cars need to be auto, like my wagon. But you wont get the best out of the 3.0s power with a manual. But you will be able to go from 0-60 quite fast while holding a cup of tea (insert favourite beverage here) in your left hand. A well set up autobox is a very nice thing. I can drop up and down a gear exactly when I want to in the 190, just with minor movements of my foot. Or control it with the shifter when needed. The wagon is totally the opposite, but its not so important for that. Simple answer, both are good choices

I always thought I wanted a manual box in my 2.6 but to be honest 99% of the time the auto was exactly what I wanted it was only those few occasions that I think I would have enjoyed the car with the manual option more. But I do think that for the vast majority of time the manual box would have been laborious. If it were me I would stick with the auto, with the bowden cable properly adjusted and the box serviced it made the 2.6 quick to respond so with the extra torque from the 3 litre I doubt you would find it lacking.

Mate, will definately let you have a go of mine (standard mb manual box) because with hindsight I think I should have started with a auto |

Thanks for the input Sportlinestu & Brett. Brett will have to take you up on the offer of a test drive in your manual. My wallet and head is saying just drop the 2.6 out and drop the 3.0 in and jobs a goodun, and worry about a manual later on. If i was to keep it auto, would i have to change over the engine 300e auto box and ecu together or would the enginge suffice???? |

thats a relief to know, its handy when you have a complete car rather than just the engine. Does the ecu control things like aircon etc or just the engine side? |

Blimey, how many old Mercs have you got! Post up a few picks of your lockup, it must be a little gold mine. Let me know if you decide you don't want the 2.6. |

Your top of the list duncan. The mercs are scattered all over the place. One of the W114 is located in an airfield outside luton and one is in my mechanics car park. there is a post of mine where i have shown the w114 I think |

I love the w114/115 coupes and the idea of a pokey 2.6 M103 under the bonnet does sound appealing. Sounds like you gotta lot of projects on though ! Cheers Duncan |

seen that one, looks ok, but takes the fun out of doing it yourself, so the ups and downs of a conversions are not experienced. I mean if it was under a G note one could consider it. But I got the donors waiting for alease of new life. So when we gonna go for a spin down lower sydenham then inf your manual box????? Edited by PARI, Tue Sep 20, 2011 10:22 pm.

Well when the poxy thing is actually working you will be the first one to know ! Should hopefully be this week. It's alright so long as you don't want to slow down (stalling problem) |

I am looking to do a bit of polishing/porting and don't want my car off the road for ages. If I can prep up a different head I can have it ready should any leaks or head gasket issues start appearing. Also want to do the polished cam cover like Smiffy's but as I say this is my daily so I need it to get to work. Not as big a project as yours but enough for me, just some subtle tuning/tweaking to recover some lost horses perhaps. |

thats my estate mate, just thought which one would be better to deliver the donor engine but the TE has a ASD diff so didnt know if it was better, dont want to get halfway there and someone say oh you should have stuck an asd in there while you were doing it thing. |
