Thanks yes I was reading and getting a better idea, and this is most helpful. I guess my other question would be that if I did a new wiring harness{as I know MB made early harness with biodegradable coating on early 90 cars} if it is bad, as I am just looking to swap for a Sunday driver not really looking to increase speed or horsepower over what the M104 3.2 has. I sold my 993 Carrera last year as I had only put 10,000 miles on it in 15 years.I guess what I am asking is that if I just keep everything stock on the car that would not be driven maybe a 1,000 miles per year is it that important for stand alone ECU and changing the throttle body? Thanks First off, buying a new harness from M-B if available will be in the order of a thousand bucks but I'd expect more, getting it made by a specialist would be c.500 bucks. Sunday driver or not, the real point of fitting a modern standalone system to a project like yours is reliability and the automatic bonus is better fuel consumption along with a performance gain, I doubt there would be a major gain but possibly in the order of 10% keeping everything else factory. Now, and this is only my opinion, it really doesn't matter what system the 300E has beit an M103 engine with Bosch KE-Jetronic or an M104 with LHW, both wiring harness will be trouble unless already replaced which is a possibility. Even if it's a KE-Jet system where the harness is not biodegradable they still give trouble due to age and KE parts are expensive (ask me how I know!), a reconditioned metering head alone is c.1000 bucks. Also, not every shop can set up a KE system correctly. The system is not very friendly to the amateur home mechanic like ourselves, it's not efficient either, even when running correctly compared to later injection systems. As for your intended low mileage use, that only makes matters worst. Old cars in particular need to be driven, again it's only my opinion but that's even more of a reason to fit a standalone system. On a more positive, cheaper and easier note, maybe the 300E has the LHW system and the loom along with the throttle body has been replaced by previous owners, if so you are on a winner. |

I really do not understand the stand alone system and was planning on doing the swap myself. Going to do my homework to try and understand. I This will give you an idea. Hope that helps. www.hpacademy.com/courses/efi-tuning/?gclid=CjwKCAiAzJLzBRAZEiwAmZb0asWax9s-svb81AH3KjiX_LHb4oogMbFtsaEsUzKhSBPMLsmFCnOx6hoC07YQAvD_BwEBasically, you ditch/junk all of the current engine's electronics, injection system (and ignition system) and use an off the shelf engine management system. That will entail buying a kit with an ECU, wiring loom and adding a few sensors (iat, map, eng temp, o2 sensor) plus a crank pick up etc. Then there's a few bits for the ignition system depending on which system you opt for. You'll need to add a throttle body (maybe a BMW M30 530/535i or something similar), have the whole lot fitted and then tuned by a local tuner on a rolling road. As carat 3.6 mentioned some tuners have a preference for a particular after market programmable ECU, so ideally you should speak to them first and go from there would be my suggestion. |

more than likely the 300E loom is already deteriorating and removing it won't help. [/span] [/quote] + 1 for that, the loom and the throttle body are just problems waiting to happen.[/quote] Simon, that's a good call on the throttle body. |

I will do inventory of electronics from the 300E for engine management and list. |

If new plugs doesn't cure it, more likely it's one of the coils which is not uncommon.

Nobody ever seems to mention what imo is the most un-noticed fast car ever - Citroen Xsara 2.0 VTS. I had a go in one at work a few weeks ago, first time I've driven one for years, and I'd forgotten how good they are. Literally like the tyres are glued to the road in corners to the point the owner was white as a sheet and hanging on for dear life in the passenger seat (after he'd told me to give it some stick). I wouldn't touch anything with a TSI/FSI/TFSI engine with a great big curse word stick. Dreadful engines. This man speaks the truth! Xsara VTS are mega and I can't believe they aren't more popular. And TSI/FSI/TFSI are the most overrated tat going. Literally everything about them is terrible! Overrated is right! I wouldn't touch one. Then again I think all modern VAG stuff is overrated, most will be recycled by the time they're ten years old. |

A little here, a little there means you're winning. I should take a leaf out of your book as I've been making excuses not to into the garage this weather. Keep up the good work.

Mercdan, also consider the sport alloys know as Corvus. Come in 7x16 and 8x16. Usually on fleabay at reasonable prices, currently there's a set in Wales starting @ 75 quid.  |

Thoughts so far are: 90's 2.6 Audi A4's (quattro) or Audi 80 coupe (2.6). Honda Accord 2.3 (not sure how fast these are unless Type R's, but they're over £3k for non-ragged). Toyota Celica ? VW Golf V5 (170bhp) or V6 2.8 204bhp. Had a Mk4 before and it was a good car! Ford Mondeo 2.5's have 217bhp or ST-220 and somehow are only £325pa tax??? Out of that lot I'd pick either Accord. Ideally, a Type R but the 2.3 is a cracking car too and you'll pick a tidy one up for a grand. Not bad for a fairly bulletproof motor. I wouldn't say no to a late 90's Celica 2.0GT either if you can find a nice one. Good hunting. |

Looking good. You might need to change the rear spring insulator (they're only a few quid each). Suspect there is a 4 nib currently fitted, a 3 nib might be perfect? Keep up the good work.

Good enough for hobby use I'm sure. Tbh the market for those kind of tools has levelled in recent years now battery tech has plateaued and most stuff is made in china to a price anyway. Theres not the wide gulf between your ryobis and boschs that there used to be. You could right. But, I've nothing but great service from the likes of Hitachi products (don't know where they are made, possibly China) and I'm usually willing to spend the extra over the likes of Ryobi etc. One point worth nothing about Chinese made products, is there's good and bad. It all depends on what the customer requirements are from the Chinese manufacturer, be that Bosch or whoever. |

I like the fact they offer a repair service and clear well designed website with good choice helps too. Both of those would sway me to buy.

Well worth visiting the Classic Remise in Berlin or Dusseldorf. Lovely places, not crowded, great cross section of motors, dealers and repair shops. Both are free with nice restaurants.

Wow, you are a brave man, well far braver than me to take on an XJS. Hats off to you. Enjoying the thread, keep up the good work.

but for most simple jobs a couple of large trolley jacks will do so I can't be bothered to get it out! Sort of says it all really. |

Splitting the building into two units does put a different slant on the situation. Still, I reckon it's important to write to them, nothing like a hard copy that's dated & signed for.
