Hi,

With Beemers being all over the place, rwd and all alloy engines there must be a really good reason nobody uses there mechanicals in a locost??

For example:

M42
Straight 4 cylinder DOHC 16V. 1989-1996. 100kg 220lbs
Used in E30 and E36 318is, Z3
1.8 (138-142bhp)

Many thanks!


Paul

The best of the BMW's 2.0,2.3,2.5 etc are straight six engines that are quite long and are mounted at an angle of about 20degrees off the vertical. if you could fit it in it would be a nice motor but you would struggle in a locost, apart from maybe the Viento from Luego.
I dont know if the early blocks are alloy, if not it would be a heavy weight.

i think the problem is they dont fit the book chassis so good.

a 442 on the other hand isnt a problem

Wots a book chassis Dont see any problem getting my lump and box shoe horned into somthing suitable. Now if that twat Hippy got his arse in gear we might have em chasing each other next season. Fancy hogmany in Glesga Richard?? Dont Know what my welding is like under the influence. Must practise that technique on his Chassis first I suppose
Shug.

a 4cyl may fit a book chassis better , a 6 cyl is quite long , but then i get loads of room round a volvo 6 cylinder in a 442 .

its not as common as the ford because of price .

the engine is on the slant which makes it that much wider as already mentioned. i'd be guessing the height of the engine would be a factor as would the inlet, injection and ignition/fueling systems.

as well as being slanted, they are quite wide at the base, which is the point that a locost engine bay gets narrow.

I would also expect a beemer to be a bit more costly than yer average ford donor

i would use an 4cil not the big lump 6cil.

the reason is that it would me an really big/heavy engine..

altough we aren't talking about an alloy one?/

i judge about the old cast iron blocks..

i think if you get it fitted go for it else drop it.. (i mean the block it self, not the anx..)

From the mid 1980's there are two types of 2.5ltr 6cyl BMW engines... the small block and the large block.

Small block engines are not really that small but if you got rid of the standard motronic fuel injection and fitted carbs/TBs then the height of the engine may not be too much of a problem. Sump may still need changing as its quite low.

Its an engine with interesting characteristics - my father-in-law and I have just finished fitting this combo (2.5 6cyl + getrag gearbox) into a marlin sportster.

Very nice mid-range torque and just loves to rev, but always feels as though it could rev about 2krpm more than it has the rev limiter set to.

Hmmmm ARP bots and a RR session soon me thinks
