    F/I build advise

    Hi all.
    I will appreciate if somebody could advisde me the best way for my engine rebuild (m54 3.0l).
    Currently I'm planning to order 8,8cr CP pistons and don't know what is the best solution for the block sleeves upgrade, coz they look too thin as for me.
    My goal is to rise the boost up to 14-17psi as for a daily driver, nothing serious.

    Thanks in advance,
    Boris.

    Welcome Boris.

    In my opinion, we have the two best guys in the M54 community here to guide you. PEI330ci and bluejeansonfire, they will point you in the right direction.

    Welcome Boris!

    I'm in the midst of a very similar build for my street car.

    If your budget is X I'll advise something different than if it is Y.

    If you want, you can PM me your budget and I'll post a rough parts list here....

    You're welcome Boris.

    That's a solid plan, and I hope to see you on the road with it soon.

    We exchanged some information yes...but I don't think I'm his only source of information.

    I also don't like to publicly talk about costs.

    I was just wondering, because it went from I have some questions to this is what I'm doing, lol.

    My main concern is that he was taken care of, glad to see you helped him out, thank you!

    I didn't work on BMW before, that's why I was asking about engine build...that's a "dark side" for me Click here to enlarge I was surprised to know that PEI330CI knows a lot about Hondas as me too Click here to enlarge I see that many people owned BMW after Honda Click here to enlarge Some kind of grade Click here to enlarge allready made an order from CP, but I'll have to wait when they get my stock piston in order to make custom size for me as don't want to go 84,5mm CP and would like to get smaller bore size to leave stock sleeve as thick as possible. actually we have a lot of turboied BMWs over here in Ukraine, maybe you know my friend Oleg_Coupe from turbogarage, but he doesnt like my idea to push HP from SC setup Click here to enlarge he tells that I should go with the turbo setup... so i came to you to get some advise about my plan. thanks again. I see that people over here talking more about real stuff not like other sources, so on e46fanatics I'm cheking only showroom topics Click here to enlarge Click here to enlarge

    Boris,

    Are you running the 80mm pulley or 85mm now? I really believe that with a 75mm you're going to get some belt slip up top. With my 80mm I'd see belt slip measurable on the dyno after only 4-5k miles on the belt, not to mention that I had to run a very hard compound Napa belt, because the continental belts would slip right away. Have you looked in to a larger crank pulley? I'd suggest 8-rib but you'd have to have a completely custom pulley setup made for it. If you didn't have a 3.0L I'd even suggest running the 80mm to 7500rpm or so to get the boost level you want, but that crank is kind of iffy.

    It's the same crank used in the us spec S52. The long 89.6mm stroke is known to cause vibration problems when revved above 7000rpm for long periods of time (daily driven and/or race cars). A lot of the high HP e36 guys get away with revving it to 7600rpm but they aren't daily driven. Most of those machines are for drag use. The M5X motor family is known to vibrate the oil pump nut loose which would obviously lead to starvation and then motor failure. Bimmerworld and Turner sell kits specifically to solve this, and race teams even have their own pump that was redesigned to solve this issue. I think ATI also makes a dampener to try and help out at the higher rpms as well. However, all of this costs $$ and it's usually not worth it for a daily'd street car.

    My initial intent when I had the supercharger kit was to push as must boost as I could until the motor failed. When I realized that I was already getting belt slip with the 80mm @ 14psi I gave up. It'd cost too much to have a custom 8 rib setup or larger crank pulley made. AA switches to a complete 8-rib pulley setup with the e46 M3 kits to avoid the belt slip issue. None of the non-m cars ever needed it so they never produced it for us.

    Probably because of the @ symbol anticipating an e-mail address.

    Can't you just use the S50B32 crank?

    It doesn't share the same stroke. It's 91mm vs 89.6mm.

    I believe so. I know the US spec s52 uses 135mm as does the M54b30. I think the s50b32 is a little longer.

    edit: just google'd it. The euro motor uses a 139mm rod length just like the S54.

    Why would guys with the US crank want to rev that high anyway? If you know it is an issue at 7500 and up why not keep it around the stock 7000 rpm?
