Authentic alpina 2.7 engine

[whiterhino]

As title says really.how can you tell if an alpina 2.7 engine is authentic.What about the ecu aswell.Will either have distinguishing features.

[Speedtouch]

The ECU should have a red Alpina sticker on it, with the model/build number to match the dashboard plaque/chassis plate.

Speed touch is that located under the dashboard .the car in question is a replica. The owner claims all parts are genuine including engine and ecu.the pictures suggest it is but I'm useless with computers.its on another website.no engine pics tho.

[Speedtouch]

Yes, the ECU should be in the normal place; just remove the trim panel below the steering column and look up.

It will probably just be a standard 0 261 200 173 ECU with an Alpina chip in it.

If the block is genuine it will have C2/ then the engine number stamped into it on a flat section of the block bottom on the inlet side.

[M-Sport]

Would a c2.5/c2.7 head have any Alpina markings on it?

[Rodderz]

An Alpina head will have a 4 digit number stamped into it, on the inlet side, just below where the cam cover sits.

[M-Sport]

So most likely the build number Sytner gave the car when Alpina conversions carried out right?

[alpina123]

2.7 should also have a 6 branch and i know some c2.7 have black inlet manifolds and rocker covers dont know about the 2.5 though

As above but most of the original alpina 6 branches have rotted out by now and are long gone.

ALL genuine 2.7 engines had dark grey inlets and rockers. The 4 digit head stamping are done by the man at buchloe who built it. The number on the block on a UK supplied car will read C2 2 then the last 7 digits of the chassis number of the car it was fitted to.

There is another flat section on the block below by the dipstick. Often a 4 digit stamping here also.

[Speedtouch]

The ECU should also have a label with the last 7 digits of the chassis number on, so you could check that the numbers tally with those on the engine, to be doubly sure you're getting an Alpina setup.

Thanks for all the input guys.the vendor has sent me a few pics by email.sadly none of the engine or ecu.they are of the seats and various other pics like the wheels and stuff.basically the car is an alpina replica that the vendor claims is all transfered from the donor car.wheels and kit seem spot on.but the engine and ecu are my concern.the car has a btb 6 branch and he says he has a receipt. The car is advertised on car and classic.as you all know my skills on a computer are tragic.maybe one of you even knows the vehicle.theres not many that zoners don't know.

Much appreicated

[Rodderz]

Not all conversions have dark rocker covers or inlet manifolds!

[whiterhino]

Look guys feel free to express your thoughts.i actually hope someone knows the car.i have an offer in mind if the engine and ecu are correct.if not I'll hold my folded.im no expert that's why I'm putting out the feelers

[Speedtouch]

I would suggest you check the engine and ECU first, to be sure of what you're getting.

[brettski]

If the viewings are to take place at an e30 specialists then surely they can show you where the stamps are on the engine?

prove it, i'd bet money. I've NEVER seen a proper C2 2.7 or B3 2.7 that hasn't left Alpina like it

[whiterhino]

Seems nobody knows the car or has much to say about it. You lot usually have lots to say

Simon is spot on that's I have known them to be ,I have owned three and they all came with black covers n manifold

[Rodderz]

Well, it is a fact that they didn't!

[e30_mtec]

Any one have any info on the car in question?

[alpina123]

Well, it is a fact that they didn't!

Have you had the car from new? If not they've probably been swapped with a 320 or 325, either that or the whole engine has

No I haven't, but, it is the original engine!


Look, do your homework, and you will find that I'm right!

We'll how do you know it's the original engine then and how do you know the bits haven't been swapped with a 325i

[e30_mtec]

All original parts.....
ECU is a pina one...

Not to sure on the engine as i couldnt see the engine number
Proud new owner _--_--_--_
Possibly one of the best e30 iv driven...

[alpina123]

Did it have a 6 branch manifold

[ajay]

Funny enough, i know the history on this one, the block has been changed but all the internals and other alpina parts are definatly 100% genuine Alpina, ( engine c2, 2.7 for sure) the seller and previous to him Alpina owner are hiding nothing, its as close to the real thing as your gonna get, it drives and sounds pretty awesome.

[jonny323i]

Why was the block changed
