BAD 300E project commenced
Hi all, was told about you guys from 2 other forums. I have recently purchased an 87' 300E that has been well, kinda modded
It has however suffered @ the hands of the previous owner/builder. Let's say I got it in the nick of time before he well & truely crucified it! I need some parts & advice so, here it is. I'll wack up just enough pics to show you the car & that I am serious. As you will quickly see, this previous owner has spent alot of $$$$ & love/time on this. It has forgies & MSD stand alone for fuel/spark. Also, it runs on constant LPG via mixer! I intend to finish & fix uo the balls-up so to speak. Right now I am in process of removing engine block & taking it to my builder for resurrection. It's hard to believe this engine has done only 4k since full rebuild, although it was done some years ago & has sat & well, is stuffed now! First part, I am after is a custom exhaust manifold. The spaghetti/spider type with equal runners. Either stainless or steampipe. It currently has modified orig' 2-piece manifold. Not my favourite Turbo is currently TO3 highflowed to TO4 but, looks as though it has succumbed to same fate as poor engine. So, if I get another turbo, what are good performance options? I am turbo savvy but admit, right now to all, not Mercedes savvy & am willing to learn from ones that know. Any advice is very appreciated. I know & have read of stock M103 engines with twin turboes etc. I am interesterd in this engine seeing the full potential of bullet-proof bottom end taking way more boost than 7-10psi. Like, 20-25 @ least. Here's a pic of the similar manifold I'm after. This is actually from your forum: Car Pics: Last edited by BAD300; 02-03-2010 at 06:13 AM. |

I'm afraid I'll be learning from you more than I'll be teaching.
Two things I would advise however is for you to install the piston oil squirters and windage tray from the M104 if that hasn't been done already. That header is for a four valve head. (But you probably already knew that.) This project is cool. (You probably already knew that too!) Jay, isn't this thing cool? Regards, Eric

I know this car is wicked but I must confess I'm just starting with it. The last guy gave up after he let it sit too long
My first step, since I'm forced to rebuild engine is to toss the stock ext mani. Any advice from here would be great! thanks guys |

For some reason the fuel injector bungs are plugged on your intake, I guess it's an older fuel system than the CIS fed M103's have in the states. Get a stock manifold with the fuel injector bungs(or make one) along with at least a fuel rail and 36-1 trigger wheel from turbobandit.com. With those you can start putting a new ECU setup on the car to handle the turbo a lot better.

there is no CIS like this on any merc, seems like its been converted to some sort of carb system!!!! or just TB Injectors.

Gentlemen, that's not CIS. Read the first post. That's and LPG mixer.
He's runnin' off the stuff you make your hot-dogs with.

I may be missing something , but I don't see injectors on this pictures. All I can see is the LPG evaporator (think thats what you call it). Looks like this is a very old LPG system, the new ones are injected and work very well . Looking at the pics I also think this car runs only on LPG .
P.S. is there a mixer on top of the throttle body ?

ya and silly us guys cause the OP mentioned it in his post :$
edit: its either all of us were posting at abt the same time, or non of us are reading here, but for MAG. hahahah and Mag as i have heard LPG has high octane and thus will resist detontation better. its just that u need alot of it to reach proper AFRs

hahaha rofl, musta looked quite weird if you didn't read the finer points
Can anyone suggest where I can get a hold of a good custom turbo exhaust manifold then to suit this 12v head? Just to clear up the set up car is running, it's running Air Research LPG mixer set up, as seen on inlet manifold in pic LPG mixer is managed via MSD stand alone, as in bottom pic. Yes, it would be better system if it had LPG injection but, mixer still can work well. I intend putting bigger LPG jets in it & dynotune properly once engne is sorted. The block has been o'ringed too. Whether car has sat with old coolant in it or seller run bad tune etc, I don't know but I have had to get a reco head & now need to have engine rebuilt again. To save anymore confusion, here are some pics of the raped engine You can see the heat problem the head suffered: This shows rusted, grooved bore. Just to think it's done 3k since build with forgies |

The only other problem is that LPG doesn't have any lubricating properties that gas has on the valve stem, so you get much more wear on an already stressed part. There's pro's and con's to both.

A mixer indeed yield good results but I believe it is the tune ie AFR that is the concern here. This engine has suffered heat/corrosion. No brainer. Just what went wrong I won't know fully til' rebuilder has a sqiz. I believe it ran too lean amongst other things. Rebuild was an abortion full stop! On a brighter note, I have sourced a brilliant LPG man near where I live so, will be talking to him soon. He does the Gas Research conversions down here. After rebuild, he can get it right from there. Quote:

LPG has an octane rating of 110 (R+M/2 method. It's actually a higher number when rated by the Euro rating system). This means you can run way more boost before detonation occurs (provided the AFR is correct). That's why I said this car is cool.

Solution. Convert to EFI and run E85. 105 Octane (R+M/2) and cheaper than regular gas(at least here in the states). You'll have to update the lines and use a more current fuel pump like a Bosch 044(About $200 and flows enough gas to support 685bhp) but it's worth it.
