[Dezzy]

+1

1 with an auto
1 with a cab

nuf said.

Both heavy cars eh, still quick though

I know just joking. Not as quick as my M50 though. I hope

[Rav335uk]

I have a few more bits comming for my M30, hopefull in time for the "Shoot out"

[Jhonno]

Wow.. So much talk on this thread.. The M30 was that great a lump bmw didnt drop it and go down the 24v route then... Oh wait.. Mind you, what would they know.

isn't your engine obsolete now too?

[Dezzy]

Right everyone who hasn't got S54 or newer your cars are sh!te and slow. Get over it ha ha

[Rav335uk]

Well mine is toooooooooooooooooo old, shi7 it's 20 yrs old, and can still keep up with modern day cars

[Dezzy]

My car is c 86 so it 24 years old. Motor is brand new as of this week so happy days.

Yes.. The basics have only just been phased out in the quest for the 'power race' tho.. However, they are still using the same number of valves/cyl etc.. 100bhp/l vs. 60.. Hmm.

[gareth]

how about BHP / £?

this is like top trumps

[DanThe]

BHP per litre = 87
Power to weight = 210bhp per ton
BHP per £ = approx 0.1

[gareth]

BHP per litre = 87
Power to weight = 210bhp per ton
BHP per £ = approx 0.1

ouch!

BHP per litre = 64
power to weight = 156
BHP per £ = 2.2 (engine cost) or 0.5 ish for whole conversion after flogging off leftovers

[DanThe]

Im working off engine/instal cost

[gareth]

If I remember correctly the start at 1330kg and go up depending on options. I stand to be corrected though.

just found a figure on here:

328i 1395kg
iiiiiinteresting

[DanThe]

Stay at home tim!!!

An M50/52 looks like it should have been there from the start. I personally think the M30 has a nicer sound to it from the various cars I have seen in the flesh. Dan's beat is retardedly rapid but Ravi's cab just sounds so nice and it's a great cruising engine.

Dan get the 3lt out and show these what it's about slipping clutch or not it'll have these m30 homo's over
Dezzy, you should be well impressed with what is in yours. The one dan built was definately worthwhile doing

[Dezzy]

Cheers mate. I should be a weapon then?
Just need to snow to f*ck off so I can get something done.
Dan smoke these fools.

[Bob_S]

Should be just don't put one of those poo M20 clutches in.. me and Dan put a brand new one in and it slipped from the off

[DanThe]

Almost makes a 2.8 seem boring doesnt it Bob
Dez has got a paddle clutch, still not got mine sorted

[Bob_S]

2.8's are so last year, we know this dan
Good on him, can't you use a paddle clutch? You need to get it RR after you've sorted it

[toby]

No one ever seems to mention in these "which is better M30 or M50/2?" threads that the engine management in the M50/2 is way more advanced and you get a MAF upgrade in with the bargain. Bhp figures mean so little in the real world but the flexibility of the engine and the way it delivers does, especially for a road car.

What about a separate thread of who's going to compare their engine conversions in an actual race? Track and straight line times would be interesting. Names on a list... that sort of thing...

[DanThe]

I am 'enquiring' about a paddle clutch, not had much enthusiasm to do anything this last week though
Looking forward to a RR test though

1/4 mile times have already been posted Toby

[toby]

I know but there seem to be so many newer conversions recently an update seems relevant.

[gooner1]

So, and apologies if i,ve missed this in this thread., how does
the M30/ M50/2 conversions, compare to the 2.8 stroker build
In terms of performance/reliability , costs and ease of conversion.

[toby]

It's difficult to compare since the differences depend on how much is spent on the M20 2.8 build in terms of cam, vernier pulley (if required) and also the engine gets a rebuild. Engine swaps are generally cheaper but the engine might need a rebuild too.

No need for a vernier on a 2.8 build.

The thread is only a month old..
