What's a built bottem end n54 worth?

[Ninjaspartan 23]

Hi all,

I'm just toying with the idea of selling my 335i and was wanting some input on what it is worth. Any input on a ball park figure would be much appreciated as I don't know, thanks!

Short history, took the car for some fun to Hampton downs, spun a rod bearing, crank could not be saved so I put a built bottom end with brand new crank at 158k kms in early 2018. 

Some of the mods below, along with the usual things, coils, plugs, water pump etc. 

• 2009 e92 N54 with 203k kms 
• DCT 7 speed  
• Bilstein B8 shocks and Eibach springs 
• JE 9.5CR Forged Pistons @ 158k kms
• FCP Engineering Forged Rods @ 158k kms
• New Crank @ 158k kms
• King main and rod bearings @ 158k kms
• 5" intercooler
• 17t turbos and Wedge tune @ 173k kms (July 2020) 500+ hp
• Walbro 400 LPF
• New HPFP @ 182k kms (March 2021)
• M3 front control arms 184k kms (April 2021)

Cheers!

I would have to guess somewhere between 12-18k,  big range sure, but at nearly 200,000km? any new owner is going to be worried about crossing the 200km threshold and incurring the depreciating hit that comes with Kiwis not liking high mileage cars.

I doubt anyone considering a 14 year old car is concerned with depreciation

It really depends on the condition of the engine and the specific parts that come with it. Generally speaking, you can expect to pay anywhere from $2500 to $4000 for a complete N54 engine with all necessary components.
