    Yes, but I'm asking if it would be better as a single design and not split.

    The bed plate is a good idea for a high reving block,as it is stiffer than individual bearing caps

    Is what the guys I usually use for stuff like that charge.
    8k is about material only..

    Because it has nothing else than bolts to fix it in position.

    I don't mean to scare you...but the custom billet blocks for Pro-Mod engines are in the $70k area. That's just the block...no rotating assembly.

    I think there are other ways of approaching the bed-plate issue...and I'm interested in it because I think the S85 is the highest displacement BMW engine with high BMEP potential.

    I feel the same way regarding the S85.

    Suggestions since a custom block seems to be out of my price range?

    So reliability wise in an FI setup: S62 more reliable than S65 based on engine architecture? Hmmmm... I wonder how much are E39 M5s running now a days.

    Funny you asked. I can't help but look at the E39 M5 advertisements. Much like the E46 M3, $20-25,000 will fetch you a well maintained model. North of $30k and you will find the cherished garage queens.

    They both don't have thickest of cylinder walls. It's tough to say we haven't seen super high horsepower S65's yet. Clearly there are areas of concern.

    Low boost setups stock S62 blocks handle easy.Everything north of 650BHP needs a sleeved block with dropped compression ratio.

    The math is easy,for the amount of money a E9x M3 costs you get an E39 M5 with fully rebuilt engine,suspension,coilovers,custom diff,big brakes and a s/c with around 600BHP.

    So a new car on the mechanical side of things.
    And the only thing the E39 sucks is infotainment.Put a Dynavin in it and fine.

    The E39 has an amazing build quality,still after 10 years.Everything just feels solid.

    Plus another thing,understatement.

    Build an E39 M5 with these specs,remove all the M5 badges,so it is only quad exhaust and mirror left to identify it.
    It is so entertaining to go out and slay modern sport cars(AMGs,GTRs,Porsches,...) with a 10 year old saloon.



    I think I am closing in on the bedplate,Joseph.

    Since you are an expert i have a question for you. Does sleeving an aluminum block make the block structure weaker?

    If the sleeving is done correct(that the sleeves are tight in the block),it does not weaken the structure of the block.On many aluminium blocks it can be considered as reinforcement even.

    There is S62s out there pushing 700whp with sleeves reliable.

    I have always loved the E39. It is one of my most favorite chassis of all time from BMW. I dont know what they did with the leather, but those and E38s always had the same interior smell as they aged.

    I would still like to get my hands on a 540i 6spd or an M5 somewhere down the line.

    Greetings gents,

    First post over here, long time M5board member and we are starting to see our fair share of rod bearing issues on stock S85s over there.

    There is a ton of great information here, so looking forward to any more thoughts you all have.

    I noticed the S85 rod bearing part numbers have changed. Does anyone know if there was an actual improvement to the design or just that the new bearings are lead free per regulations?

    Apparently the quasi-dry sump on the S85 doesn't really help out in this area much either...
