    Cost of a S65 low compression engine build

    This summer I am looking to having the engine in my m3 upgraded for future mods. I was hoping to do a low compression build using some beefed up rods and a sleeved block. I am used to building a audi 1.8t but the M3 is still a little new to me. Just looking for some ballpark prices on the pistons/connecting rods plus labor, sleeved block cost plus any additional machining or other work I should be looking at while the engine is out. I want to do this in a few phases. First phase low compression built bottom end, second phase gintani/ ess/ vf or turbo build if that path comes around. I appreciate any help on what the lower end build will cost with labor. Still just a little new to the bimmer world.

    How long between stages do you think and how much work will you do yourself(ie pull the motor yourself etc)?

    Factor $17k for a top quality build.

    It can be done for $15k as well.

    Do you know what that etc is though? I'm asking cause it would give me a good idea what it might cost to build my N63. For example is there a list of components in the build and which kinds? Also what labor does that include? Do you send them the motor or do they pull it and reinstall if for you?

    When I had the engine done in my A4 it cost about $5k. This included taking engine out, tear down IE rod/pistons, balance blueprint block and rotating assembly, new bearings, etc. Now that did not include any work to the head. I know that the M3 would be more expensive but I was not expecting the cost to be triple. Now I did not have sleeves put in the block, could that cost the extra $10-12k? I wouldn't think the hardware would be over $2-3k more. I know the price is what it is, but I would love to see a breakdown. Not exact prices, just a rough average for parts and labor. For example whats the cost to have the block sleeved. I for one do not have a clue. Be good info.

    Being a V8 it will naturally be double the price due to the extra 4 cylinders. Not to mention the R&D cost vs. demand is not very high..so costs that need to be recouped are enormous.

    If there were people out there sleeving S65s like small block chevys then the price would be like $1000 bucks...lol

    I would assume that the rates vary by engine shop. I dont know of any offhand around us that have touched the motor aside from Turner Motorsports. Why dont you give us a call in the morning?

    The cost of the sleeving the block isn't much but will depend on application. I've seen charges from $35 for domestic blocks to $125 for imports. Its not that its any extra work but its a supply and demand thing. I think the biggest reason you see such a high cost is there isn't much demand for it so the shops that tackle it need to make a big profit from a small amount of builds. The reason I want to see a parts list and labor is that there is alot of additional things that can be done and really raise the costs vs doing the bear minimum.

    Edit: it should go without saying but that cost is per cylinder.

    I just seen the rods cost around $2300 and the pistons are around $1800, not sure if they would have to be replaced. So yes the parts are quite a bit more. Looks like sleeving an aluminum block could cost around $2-3k based on other aluminum block v8's, probably a little more on the S65.

    Is sleeving the block really necessary though? For say like 700whp ?

    Probably not but why not do it when your already going into the motor? If your spending that much money I doubt the 3k you'd save is worth risking it since you are putting almost double the stock power down.

    In my case it includes labor and pulling/installing the motor but everyone will be different depending on who they go with for labor.

    BMW makes the cylinder spacing as close as possible in stock form with an aluminum block so it can fit further back in the engine bay for better balance. You can only increase bore by 1mm so that should tell you that you want sleeves.

    Did the 17k include any head work? Also are the other components BMW parts or aftermarket(I'd head and main studs, head gasket, bearings)? do they do any other work to the block or heads?

    I can't get into this too much but the majority of the parts you mentioned are all aftermarket.

    New valves or a valve job on the stock ones? Sorry didn't know it was being kept under wraps. Is it a package that they offer or just something they put together for you?

    Each build is basically a custom package.

    Valve job on the stock ones I think but don't quote me.

    Might as well spend all that money on the down payment for an M5.
