i may have found an engine donor for the merc......  '94 750 alpina. complete car, very cheap, no mot, etc. only bit I'm interested in is the 5L v12. figures i can find are 299hp for the v12, but wont an alpina have been breathed on further? i don't mind keeping the F.I. as it looks pretty cool, so a remap may unleash more? i assume they're all ally, are they good engines? tuneable? id havta get a manual stuck on the back of it too... |

I'd be a bit wary of the BMW V12s.
A while back I was looking to buy an 850CSI which has a slightly larger than 5.0 V12 and EVERYBODY I asked regarding these engines told me to steer clear of them and buy an 840 instead.
Apparently they suffer from oil derived problems and like to explode! (I cant remember wether it was that they have Pourous blocks or something else!)
But they are horendously expensive to service and repair!
On the upside if you did go with one you can use the CSI gearbox which is a six speed manual and you could tell your mates that you have the same engine as a Mclaren F1 ;D

just found this- Cylinder V12 60° Capacity 4.988 cccm Drilling 84 mm Stroke 75 mm Compression ratio 1:9,5 Rated output 257 KW/350 HP with 5.300 U/Min. Torque 470 Nm with 4.000 U/Min. Motor control BOSCH Motronic M 1.7 Fuel Super lead free which sounds quite promising, 350hp stock  looks quite nice too   ive read about them being sensitive to oil cos of the nykasil liners, but this car is cheap enough for me to not have to worry if it does go bang...... id be paying £1.42 per HP, and thats before selling any of the rest of the car off, like the big fat alloys on it, or the full leather interior, etc. |

has it got alpina badged plemuns? if so its breathed on, if not its probably just a stickered up one. they're about 300bhp as stock, first gear in glemsford built a supercharged stock engine with about 600 ponies in it for the gumball. thing is, apart from porosity or forcing to much boost through 'em, they're nigh on bullet proof, its everything else that's around them goes wrong. £500 for 6 plug leads sir? (there are others that fit ) and yes, they do snap! fly by wire throttle bodies go wrong almost alarmingly, we (at the bmw specialist I work for) get about £200 upwards for throttle bodies. none in stock ATM. 2 ecu's, 2 TB's, 2 air flow meters, 2 dizzy caps= 2 head aches every time. there are ways to simplify it though and manuals? forget it! unless you can adapt something else (not really that difficult) manuals are very few and far between. also a pattern part clutch is £320  if you want any more info etc., just ask, been doing bm's for nearly 10 years now. |

well, the car is running, driving, 100% working, etc. ive only seen the outside, but my mate who put me on to it been out in it scaring himself on the bypass, and hes seen in the engine bay, and in his words 'its a real one'. i wonna pull the lump and stick it in the track/street merc. i know itll fit cos its got no inner wings and the engine bay is long enough for a i6. I'm capable of adapting a different trans and making a clutch work, etc. how can i save some dollar on the rest? id want it stripped down as far as feasably possible but without loosing any power, hence me wanting to keep the stock F.I. but with a remap to possibly gain a bit more. i assume its got PAS and aircon pumps that can go in the bin... id need to change/modify the exhaust from the headers onwards too, would that be a problem to the running of it? how complicated is the engine management wiring? possible to strip out all i don't need? how close to colchester are you? I'm fairly local too. |

Top grammar tips!
Bought = purchased. Brought = relocated
Lose = misplace/opposite of win. Loose = your mum

I think you'll all find that it's the V8's that suffer the nykasil problem- the 3L V8 and 4L V8 and some alloy straight 6's.
The V12's are a wonderfully unstressed engine and very light, even for an alloy engine. IIRC they only weigh about 5KG more than the old M30 engine.
Google it, and you'll see. Also the ware of the nykasil liners was due to poor quality high sulpher petrol that we used to use in the 90's, the Jag V8's are known to suffer the same problem.

Not wanting to curse word on the fire but if this is a true Alpina (sounds like a B12 - derived from the 7 series) please don't break it. They make like 100-300 of each car hand finished in Bucheloe, away from the teutonic clinical Munich factory. It would be much better to break a standard 750 which can be bought for peanuts.
I won't report you to the Alpina Register just yet but watch it!!

how close to colchester are you? I'm fairly local too. about 25mins away from you, or you could always say hi at mods and rodders meet ask nessie who I am  as far as managment is concerned, i'd be thinking about getting 2 m50 or m20 engine looms (m20 is possibly simpler, m50 is coil on plug tho ;D) and using a pair of m50 throttle bodies. still 2 ecus, but theoretically they don't need to talk to each other. the communication on the original is connected to a 3rd ecu. rearwheelnicks mate with an e34 drift car ran a modded 525i managment system on a v12, be nice to know a little more on that car. you can possibly run it on the original managment, but I don't know how. I know what wires do what in some places, but i also know kit car peolpe have had a terrible job getting them to run outside the vehicle (lambo reps). I know a man who's done it tho. exhausts can be butchered/removed as ness. but you may or may not need a lambda, depending on the managment you choose. you might be able to use a bmw manual f/wheel from a six of sommat, I can't remember if the bolt pattern is the same or not TBH. hope that helps |

I won't report you to the Alpina Register just yet but watch it!! it is a b12, and they made 305 and if i can buy it for 500 quid they cant be too desirable. the way i see it, if someone is prepared to pay me the 2k itll cost for me to get 350hp any other way for it, or swop me a 350hp motor for it, then it gets saved. if not, it gets broken..... if someone wont step up to the mark and cough up the cash to save it, they either cant be that bothered about it or it isnt worth saving. |

BMWs are a new breed to me, well anything after about '75 anyway, so ile jsut have to take it apart and see what happens |
