    ACTion! Racing m50/s50 to s54/s50b32 Crankshaft adapter



    Enables the use of readily available OEM and off the shelf M50/S50 BMW crankshafts in S54 & s50b32 applications for an extremely wide range of custom displacement options at a fraction of the cost of custom crankshaft machining while also utilizing the vastly less expensive yet more reliable M50/S50 balancer setup.

    Typically would only be sold wholesale to businesses, engine builders, & shops that advertise on this forum....not competing with BF.C sponsors, but just making folks aware that the part is available.

    Exactly....but make it 2979 or smaller for DMod!

    How does the M50/52 damper handle those high rpm's?

    Just fine according to my own experience as well as Kinetic/Sunbelt Performance Engines guru Jim Thompson.

    I don't think the M50/S50 TV dampers are more reliable or better at all. The smaller stroke is the key to reducing bending as there is more journal overlap.

    How these engines do in competition? Should be some screamers with the S54 top end and longer rods!

    Edited as I saw the date on the first post...

    I don't mean to push, but I have pm'd (MAkard)you twice in the last two weeks, as well as posting here. I Know you've been online because you posted on this thread on the 02/13/2016. I'm just trying diligently to find out if this part exists, and of so, where I can purchase it!

    I'm sorry, I have not seen the messages. It is only available as custom one off, so fairly expensive. Steve Angell (ACTion! Racing) can make arrangements to have it made if it isn't cost prohibitive for your specific project since they have never been mass-produced.

    MAkard.

    I need one! Can you put me in contact with Steve Angell at Action Racing. I tried their website, but didn't get anywhere. I would really appreciate a phone number or direct email. Thanks.

    Hi

    Could you tell me what crank, piston rods you use for 2900 and what rpm do you currently run them at?

    What price are we looking at? What is included in the kit?

    Thanks

    The crank adapter gear is the only piece. No kit.

    Ok.

    Will a m52/s50 crank fit straight in after?

    Could you email me a price? sion_hardy at hotmail . Com
