I am in Romania & have a 2nd block. No pistons, crank, or head.

I'm not certain about the condition either. I'll be going to my mechanic this week & if you want I'll ask about the old block.

Otherwise, there are a few guys down here that tear these cars apart weekly. I could try to source one for you. For the record, I am American & here for work... not gonna scam you 😂

Great thanks for help!
ebay and ebay kleinanzeigen, yes but you never know if they sell you a 250000Km advertising only 80000 all Turkish business...
Re manufatured engines from unknown companies (5000€) are maybe worse than stock used low mileage ones
except if you advise me on a good company?

Still haven't tear down mine, I suppose head is ok, but no idea if the crankshaft is scored, likely it is if a rod is broken....

pistons and rods I could buy forged ones from CP or carillo but cranck from BMW is 1700€, so a block alone wont help me much?

But at the end a complete engine from romania could be a solution
I am pushing low 400hp so no need for carrillo and cp internals

What could be the price for it?

I will talk with my mechanic today to find out if the block is okay to re-use. I do not want to sell you something that is at all damaged. I will also talk with him about finding a 2nd hand motor from someone he trusts.

I have a long relationship with him and he has rebuilt my motor, installed my upgraded turbos etc.

You might also look in the UK for a motor. Assuming your turbos are okay (RHD turbos are clocked differently) that might be a better option. 335i are significantly cheaper there as are the parts. before I decided to do my rebuild, I almost bought a motor from a race shop up there.

Unfortunately, you're stuck between a rock & a hard place. You either spend big money on a full rebuild, or you accept the risk of buying a used motor from a stranger.

I bought a used motor that I knew had high miles and rebuilt it because I wanted to be sure I would not have any more problems. (My head was cracked)

I have about 7000 euros invested in rebuilding the car and another three thousand in upgrade parts... in addition to the actual cost of the car.

4000 for used motor, 5000 to rebuild it and 2000 for upgrded turbos... is is more than the value of my car...

really difficult to decide, too sad to scrap the car and go for a S55 platform

engine without accessories would be ok, my turbos are still ok (40000Km on it) maybe a leaking injector to change HPFP is last type changed by BMW under warranty.

I broke the engine almost at idle just started, I think methanol pump kicked in and hydro locked the engine, strange noise then BOUM hole in the block. really don't know if crank can survive after a rod is broken

I am getting my engine rebuild also @H2motors in Overrath.

Get a block for 500 from Kleinanzeigen and contact them for an offer.

The bigger problem about ebay blocks is that in case of score you can't overbore... Just a light hone is allowed on alu block

N54 has cast-iron cylinder liners.

I checked and my block is toast, so that's a no-go there. I am sure you can get a used N54 for around 2300 euros. That's how much I got mine for.

IF it needs to be bored .25 mm over, JE sells a piston kit that would fit for around 1000 eur.
From there, the head and block would need decked, bearings, maybe a crank polish.

It's doable. to break down my costs a bit more- I spent 2300 on the motor, and 4300 on the rebuild, but that includes a completely new OEM cooling system hoses, pump, radiator, as well as completely refreshing the 2nd hand block.

its certainly a bummer when these things happen, but the good news is that when it's complete, you know the car is solid. assuming you have a good builder.

The best way to find out about the crank is to have it inspected. But if you're just going to source a used motor, no reason to.

Also, IDK how much it would cost to ship one across the Atlantic, but used N54s go for $1800 in the states. I have a phone number for a shop that I bought one from in Atlanta that lasted me a couple years until I sold it.

Or you could buy a remanufactured motor with a 2-year warranty from Ghassan motors. They're pretty highly reviewed in the US Facebook N54 community. $3500 + shipping for an all but new motor.

long block @ Ghassan motors without returning mine is 4500$
Do you have any good plan for shipping cheaply from the US?

Do you have a good address in the UK?

And finally any chance to find a low mileage engine in Romania for 3K?
