Swaps, Turbos, Buildups / swaping an M47 into the E30.

« on: June 19, 2009, 01:02:41 PM »

Anybody see this one?  Or know who this is?

Granted it's an M21 IDI, but he claims 50mpg and likely 10-sec 0-60mph.  That little e46 320d DI should be outstanding.  I wonder if it revs like a gas engine...

The half clip is a great idea...I was looking to buy a 180sx once upon a time and the JDM cuts were pretty cheap.  Anyone in Germany willing to source our parts?

Yeah, I've seen that website before.  Great inspiration.  No idea who it is, though.

Once in a blue moon I run across listing like this one also...

So I'm thinking of selling my 1992 325i.

Reason is, I've relocated to South Dakota and am only a walk away from work but some stinkin' long drives anywhere else.  So I'm also thinkin...

M47 into the 1992 325i?

Well, I've partially found my answer.  Apparently some 1995 318i models used the M42 and MAF, which allows the engine to breathe better.  As opposed to a M42 with AFM or a M44 with MAF.  Anyone else aware of this peculiarity of the 1995 model year 318i?  Still not sure on the decision of E30 318i or E36 318i.

thank you... but who wrote that pdf must be drunk!:D M44 use 6mm valves from factory and E36 m42 too;)
I'd want to see what those Rally heads can do with a turbo:D

Yeah, I think it is a kind-of, general, over-all, blanket assertion 'cause their other literature states that only pre-'93 M42 engines need converting from 7mm to 6mm valves.

Where is this in their site? In a pdf that I have the only "Rally" engine is M42 based...:eek:
I need more details:D

Here's the basic data: (or linked)

...If you plan to stroke it then there is no point in starting with an M44....

As soon as you start stroking, the price goes up A LOT. Add 2-3k. Boring just means pistons and does not mess with piston speeds.

No doubt increasing stroke has greater consequences that increasing bore.

I find it interesting, from reading MM's website, that the stroked:
M42 "2100 Rally" engine has 87mm 11.5:1 CR pistons and produces 205hp & the
M44 "2100 Rally" engine has 87mm 10:1 CR pistons and produces 215hp.

More horsepower with lower CR vs less HP with higher CR, seems odd.  I have no expertise from which to question this, but it still makes me wonder why such a difference.

I'm somewhat fixated on the 88mm stroke crank, so I'll have to raise my budget to accommodate it.

The MM head is not meant for the M44. The M44 uses a different cam and valve system.
The heads may or may not interchange.

Taking an M44 and just having the cams reground and up the compression or having MM work its magic on those would make for a nice cheap setup probably capable of 170-180hp if combined with a custom chip.

Thanks for the reply, Sheepdog.

Your suggested setup would leave the M44 bottom-end stock and retain the M44 head just re-worked, right?

Couldn't I also bump the displacement by using the M47 88mm crank?  And I'm assuming I would I be well advised to start with a M44 E36 318i, right?  Though, I haven't yet convinced myself whether I want a another E30 or another E36.

BTW, I assume you mean the MM M42 head is not meant for the M44 right?  'Cause I do believe MM (according to their website) offers both the "Sport" M42 head and the "Sport" M44 head.  Nonetheless, it seems your recommendation is to start with a M44 and go from there.

Not sure whether to go E30 or E36 chassis, so I'm wondering what limitations or complications each presents for building a M47 stroker.

Nothing wild, just an enjoyable daily driver; kinda like the Metric Mechanic 2000 Sport Engine (just at less cost.)  In fact, I'm thinking of using the Metric Mechanic head to top it off.

Any comments or suggestions?

Classic!

I'm a fan of 4-door 3-series Bimmers.  Yours looks great!  I bought a 1983 300D back in 1993 (gone now), and drove it for a decade before buying a 4-door 1987 325 (gone also).  Now I have a 1992 325i, and am contemplating whether to look for a 1991 318i.  Your car makes it very compelling.  Thanks for sharing.

Found bit more info about the car. 0-100 kmh (0-62 mph) 4.5s 1040 kg 245 hp between 4200-4600 and 430 Nm between 2500-3500.

Thanks for those figures.  I was looking for power specs on the E36 320d STW...I was curious to know how the race engine of 1998 compared to the tweaked engine in Alpina's new E90 D3 (with about 200hp & 400Nm.)

In essence, it appears, the 1998 race engine is about the same as the current E87 120d race car
And the Alpina-tuned D3 engine is about the same as a "chipped" E90 320d - although from watching the only vid I've seen on the Alpina D3 it looks like it redlines much higher than a stock diesel... nearly 6,000rpm!  Wow!

No idea on price.  The half-cut IS a better idea.

Boyracer, I've seen that photo of the E36 320d before (probably on your website about your 318i.)

Christoph,

I like your idea.  I'd love to build an E36 320d (like the one that won the 1998 24 Hours of Nurburgring, powered by the M47) to satisfy my own personal eccentricities.  Bimmerworld has already informed me that they can source and import a M47TUD20 for me.  Hmmmm...
