engine and drivetrain Very rare BMW 16V DOHC head for M10 block

[fdovargas]

Hello Guys,

I have the chance to get a rare head 16V for $1500 in my country, I think that the head was made for E21 race engines and formula 2 cars in the 70's, I took some pictures (night light, sorry)... and the head is in good shape, but need some parts and mods for install it, but first the pic's:

I checked the head with a stock gasket for M10 engines, and fit perfect!!!

This image show the head into E21 racing car, the intake is in the right and the exhaust in the left side (inverse to standard heads for M10), and the engine is completely vertical, mods are necessary for the motor mounts...

Awesome race engine, the same head:

Another pic:

Installed in a true E21 with m10 block engine:

The cam sprocket are different, then I don't know if the installation is very complicated. Anyone know the parts required??? I need too the sprocket for crackshaft and chain

I don't know if I need several mods for install it, and if make the parts is easy, any information available?

It's a good idea buy it??

Thanks

Dont walk, run to go get it. It is worth thousands more than that price.

Schnitzer twin cam head with a slide throttle.

jealous!

WOW. You could easily get twice that just for the slide throttle injection, let alone what the head is worth. That is a great deal.

That is just beautiful! Extremely rare. I am speechless!

Fernando,

From the picture, it appears that you will need a different lower cover. There must be another chain sprocked locted in that cover from what the casting shows to allow the chaing(s) to reach each cam, as the chain does not pass over the top between the two cam sprockets.

The inj. pump would most likely interfere with firewall.

It would be a very valuable piece to own even if you did not run it.

You have what looks like a BMW M12/7 Head and Injection assembly. If you are paying $1500 US you are getting a good deal (so to speak). I say so to speak because that particular engine is very special and ALL of the parts that go with it are likewise special (by the way, it is NOT a Schnitzer head, but rather a BMW Factory M12/Head). The engine had a special block with piston oilers and lost of other trick parts. Everyting and I mean everyting was specific to this motor. The cams you had a question about are driven from Helical gears off of the crank. Their is a special magnesium front cover that houses the gear set(s). The whole lower drive is very complicated - and made more so when the head is milled and other such things are done. If you have the money my advise would be to purchase it. I would find someone "trustworthy" near you that has experience with these motors (and can prove it to you rather than just say they do) and confer with them on a plan to put the motor together. My guess is that it will take you some time (and a lot of money) to put the motor together - you should know that complete motors that are fresh sell upwards of $35,000 and more. Parts are very rare and hard to come by so you will need to be patient. Also, because the motor is opposite of a production style motor (intake and exhaust are on the transposed from the production motor) you will need to do a substantial amount of work to your 2002 to ultimately fit that motor in there. This is one reason why the Schnitzer engines were more popular in 2002's - Chain driven cams (like a production motor, not the gears as in an M12), and oriented like a production motor - in fact the Schnitzer motor was designed FOR a 2002 and later adapted for formula racing (the opposite is true of the BMW M12/7 motor). I don't mean to rain on your parade so to speak, but you should have an idea of what your in for before you go there. Good luck with your project. I have no real interest in an M12, but I would probably buy it myself if I had access to it...just because (they are cool).

A work of art really.

Vargas.... DO NOT let anyone talk you out of this.

I would buy it just to clean up and have in my living room or garage for a show piece. You can probably use the slide throttle set up on another head if the rebuild turns out to be too expensive for you to do.

ps I should have said "looks like a schnitzer twin cam head" but it is at least as rare if not more.

That's an awesome bit of BMW engineering I'd say....probably puts out in the neighborhood of 800hp?...that's a WAG, but it "must" be fast in proper trim!

Sweet!

Exactly my thoughts....

I would polish it up nicely and impress the hell out of anyone visiting my garage. I can just tell them "it's my next project"....

Buy it!!

If you have the disposable income, it could be an investment, or has been said, a great piece of garage art.

While the head gasket may work with a stock M10, the other gaskets are VERY expensive. A year or so ago I heard about $350 each for the the split head gaskets.

There are people running these motors in vintage race groups. I'd search them out to get the real deal on actually using this rare part. If anything, you may even find a buyer and make a tidy profit in the transaction.

Good Luck!

Its interesting that everythng below the head is gone - but everything above is there. Unfortunate is really what I meant to say. These M12/7 engines are absoulte "beasts" if you have never heard one.....very, very (very) loud for a small 2 liter motor. Alot of that has to do with the gear driven cams. They are a purposeful race motor - make power around 7k and go all the way up to over 9k rpm and make anywhere from 290 to 320bhp from 2 liters depending on cams, compression and other - not much idle below like 3-4k rpm. Like most pure race motors they measure the "freshness" of the motor in hours run not miles. Lots of mag parts to them, including the slide throttle casing cam covers, and the lower timing cover, oil pan etc., titanium rods. They are an awesome engine. I just witnessed one or two running at the wine country classic -very cool. Check the link below for the "Fruit of the Loom" gruppe 5 320 with an BMW M12/7 in it (really, really cool)

I went to the Wine Country Classic vintage races http://www.winecountryclassic.com/ this weekend and watched a '78 Lola T-298 sports racer lap Sears Point to come in second in his race. This car uses a M12 engine!

I also popped in on an aquaintence, Bill Watson of Road Rockets who happens to be the engine builder for that Lola and had its spare engine on a stand. Someone like them may know people looking for parts for those M12/7 motors.....
