E30 cabrio v12

[Alpina]

Many OEM replacement thermostats already come with a small pilot hole drilled in them to aid bleeding. It shouldn't have any effect on cooling.

hehe.. i drilled three hole,, just for that purpose,,

nice fitment.. of your gauge think this is the first time i see similar setup as i have

(( Well done ))

best build I ever seen on a bmw e30. great job on details and layout.

I was under the impression that 188mm parts would interchange up to the E90's, but I could be wrong.

2.65 210mm came in E38 740d also... another one we didn't get in the US

E30 324d in UK perhaps has a 2.65 188mm.
USA has 2.79 which is close enough; the original Final drive in the m70b50 6mt cars is 2.65 (e31 )
It's a pretty clear change in BMW nomenclature in the e38/9 era.

The Rosetta stone for the transition is 1994/95 early e38 740i USA with m60b40 obd1 engines. They have 210mm rear ends like a e32 or 34 v8

The v12 750il e38 only came in obd2 and 215k kompact diff standard.

For 5 series e39 was all kompact (besides for wbs m5)
For 5 series e60 was all kompact (besides for wbs m5)
For 7 series e38 was all kompact (besides for weird early obd1 engine 740)
For 3 series e46 was all kompact (besides for wbs m3)



Kompact differential kept same for e38, e39, e60

E90 brings weird change with deletion of input flange with a giant nut substituted and also weird pinion gear to suit.

I have a e38 v12 daily; it needs lsd miserably. Best option is aftermarket plug and play; Drexler is the best avail.

Kompact = no side caps for housing and giant C clips style shims with no avail bearings or races sold to public.

Nope E30 324d's came witht the same diff as M3's 3.25. To get a 188 2.65 LSD you need an E34 525TD. Ive got one of those diffs on my E30 touring.

Well ,,, quite a bit since i posted some info about the car,,

small upgrade,,,

I was worry about the cooling temp,, the engine generates a lot of heat,,, 12 cylinder , lot of friction ,, so i had a custom radiator made for me... payed a fortune,, but the best solution so far i think,,, the temp on water is ok,, but IMO the oiltemp is way to high

oil temp is around 100°c ---- 210°f in normal driving,,, so i will buy me a V8/12 oilhousing with oilcooler output,,,,,,, so the temp can at least go down to 90°c --190°f



C´est la guerre


the radiator goes down to the bottom of the IS lip



And then i bought some hood louvres,,out of STEEL on ebay

we cutted a hole in the hood,, i stanced the outer ring so the metal plate was flush.. and then point welded it,,,,,,, damned ,,,,lots of force in such a thin metal,, the hood went like bananas,, but the result is impressive ,, even if i say so myself,,, very clean and looks like semi original

Wow! Do you have any pictures of the radiator? I'd like to see how it looks.

Fantastic work!

Thanks,,, but the radiator is in FRONT,,, of the horizontal frame,,,and from top to bottom of the IS lip,, as high as possible and between main structure frames where the bumbers bolts on ,,, i can measure it,, and tell you the size
