I just ordered the single timing chain conversion from MM.
its $250 - but I did send them my old chain + cam sprockets + crank sprocket as cores - so I'm hoping to get a discount.

Nice, thanks. $250 isn't that much more than it would cost to buy stock replacements for the chain and sprockets.

yes, correct, it is not so bad... $250 is a long drinking weekend, sometimes

Here is an email I got back from MM, just a confirmation of what marko told us.

Hi JP - gosh we appreciate your email inquiry but sure do regret this delay.
Jim looked your message over and said that we could do this conversion kit for you
BUT - you'd have to send us your sprocket. Price would $250.
Let us know if you have other quesions.

Sincerely, Mary Rowe

I've done a bit more digging an this subject, the BMW chain is a european duplex standard chain spec is 06B-2, 06B=3/8" pitch, -2=duplex chain. Based on this being a standard chain then you can go to most engineering suppliers and order a simplex (single row) version of the same thing. The IWIS catalogues suggests that it is a 120link chain, but I need to count this to be sure. I called a local distributor and the most expensive, durable and strongest chain on the market today is a Renold Synergy chain, which would outlast any OEM chain, a Synergy Simplex 06B-1 Chain in the UK comes in at �42.53+VAT @ 15% which is expensive, but not a huge amount, and I'm sure it could be found cheaper... This is made and riveted to length, not using a removable link (although emold claim their removable link is ok) You should be able to get one made locally in the US too.

wow thanks for the great info Odbod. Will have to see what i can source locally, atleast now i know what to order

one thing to keep in mind (after speaking with MM) is that the chain is not going to cause a problem - i.e. it will not break, however, MM told me that once my motor is installed with the STC conversion, I WILL have to keep a keen eye on the chain tensioner (checking it at least every 6 months) - making sure that the tension is optimal at all times.
appeareantly the chain will last fine providing there is no slack...

I'm getting my MM motor end of this month, & will let you guys know how it works out.

OT: Marko: Maybe you covered this elsewhere, but what are you going to do with your DASC?

marko · « **Reply #38 on:** February 10, 2009, 06:56:47 AM »

keeping it... DASC is going on the MM motor.

somewhat like in the thread below, but with MUCH less boost

nice! I'm jealous - but you should consider putting the setup into an E30 :cool:.

there's a DASC kit on sale in te UK for �600 at the moment on http://www.pistonheads.com/sales/886244.htm

I've not got enough money to buy sadly, too much spent on a 2.0l build

marko · « **Reply #41 on:** February 10, 2009, 07:59:16 AM »

get it man... that is a steal! I paid 3.3K for mine...

it will enhance any other additional work on your motor... not too much boost & so you do not need any crazy mods like for a turbo (i.e. designed to work with stock internals - stock ecu, etc).

yes, I should - you are right.

I absolutelly love E30s.. they have a special place in my heart, just like the 87-92 Gti 16Vs.

The early mercedes 2.3-16v motors used a single row timing chain, but they upgraded to the dual in the later model because of durability issues. I don't see a snapped timing chain thread in this forum, so maybe BMW got it right from the factory

as promised - here are the pix of my upcoming MM motor with a single timing chain conversion... the guys from Metric have been kind enough to send me some pix from the build, to salivate over.

more pix of the entire thing here:
