Differences on an Alpina.

[doug325i]

Hi Guys,

Im interested to know what all the differences were between the factory 325i and the C2 2.7 alpina beast that emerged after they got their hands on it.

Is there a complete list of modifications for a particular conversion?

If not we should make one up.

2.7 litre engine with 81mm throw steel crank. 10.2:1 compression ratio, extensively modified head, 268/268 cam (pants), light weioght Mahle pistons.

Alpina suspension with super hard sprinmgs and super hard inverted bilsteins (too hard for UK roads).

Alpina steering wheel, gearknob and plaque - sometimes alpina seats.

Alpina wheels 16", 8j rear and 7J front.

Alpina tubular 6 branch manifold (art work) + superb exhaust systems which makes superb noises.

Lots of other little bits and pieces I cant remember right now like offset top mounts, harder rear subframe bushes bla bla bla.

Can be heavily imporoved upon by just changing the cam and giving it a proper remap. Oh and geting rid of the super hard suspension.

Super!

The basics are as listed above, but really there's no specific spec as customers specced their own cars, and no two are the same.

There are some with standard "comfort" seats, some with Recaros, some with Alpina spoilers, some with M-tech spoilers, some with Alpina dials, some without, and there's different styles of steering wheel. Pretty much everything was an option apart from the engine. Even that cowcatcher front spoiler isn't on all cars.

In short, the engine is all important, the rest is up to the purchaser.
Equally, you can now order Alpina bits from BMW for your own "conversion", e.g. wheels, spoilers etc. but without an Alpina engine it's not an Alpina.

Assuming it's almost impossible to source an alpina engine that hasn't been thrashed to death, Would be feasable to build one from scratch, starting with a 325i I mean? If so any idea on cost?

I will probably have access to a decent garage next year and it would be a worthy project.

Ive been looking into the 2.7 conversion using early 325 engines, Is the standard crank up to the extra power?

Sorry about all the questions

Doug,

I have a full Alpina parts catalogue from BMW which is over 23 pages covering the entire E30 range from C1 2.3 to the B3 2.7 katalysator. It is in German but comes with pictures and Alpina parts numbers. When ordering Alpina parts you are usually asked for the chassis number, so obtaining them can somtimes be a bit difficult, depending on who you know.

It has all the bits from badges and stickers to LSD diffs incl ratio`s, roll bars, Spoilers, Digital - Cockpit ( cool part ), exhausts everything you need to build your own, but hope you have serious plastic limit, or a wife you could put to work as parts are not cheap.

If you need any part numbers let me know. I will have a chat with my contact in BMW GB to see if there would be any objection if I scanned the Alpina TEILEKATALOG and made it available. I would not want it to come back on my contact if it is not for general information.


Regards,

Dave.

I may shortly have an orginal Alpina 2.7 crank and block available. Block has Alpina engine number stamped on side. Food for thought.

Building a 2.7 is a popular pastime on here , you'll not be short of info, and it's quite cheap to do, I believe; a common path is to use the 2.7 from a 525e (E28), with various other bits.

More info to follow, no doubt...

You can build an engine that will be as good as an Alpina 2.7

Use the correct pistons and get nice high compression ratio and you will have one powerful car.

[doug325i]

Basically it's the engine then thats required then to make it the real thing! Im looking at this as quite a long term project 1 year+, and I expect I will plough alot of cash it's way, it's usually the way with these things end up.

Managed to find what I hope is going to be a mint set of genuine alpina 16s last week so thats one tick off the list! They will sit nicely on the touring in the mean time...
Really good info - thanks all.

From looking around the 2.7 does seem to produce quite good figures, Do these conversion last?

[Simon13]

did anyone remember the adjustible and fatter rear anti roll bar?

[M5pilot]

Had 3 Alpina's - never seen that on there Simon.

Maybe the buyers had enough of having their pants pulled down and decided enough was enough and no more money could be spent..........because Alpina really bend you over and give you a proper one when it comes to their prices.

[Simon13]

have a look at Demlots catalogue Sal, it has every single Alpina item offered for E30's with part numbers. I've seen it with my own eyes

Also has every part used for E30 M3's in racing form, different trailing arms,cams,bearings,wheels, light weight panels etc

Then tell me i'm wrong

[Demlotcrew]

Sal the Alpina partnumber for the rear bar is: 33 55 108

I dont know its size, doesnt say!

Hi Guys,

Part number correct for bar or could order the complete kit with part no 33 55 111 , but will climb under the car tomorrow and measure the arb thickness and also confirm if it is adjustable.

I said my Alpinas didnt have it. I have read in numerous articles about these bars so I know they exist. However I bet alot of them werent fitted with it. Especially the Sytner supplied ones where you could specify what you did and didnt want according to how deep your pockets are.
