Ordering was simple and I could split the payment, no problem. Delivery was quicker than expected — and you don't pay freight or send the old motor back. Engine was nice and clean on inspection. Very happy with it.

Engine was a good match. Just done the 500km break-in oil change and it's running well. Got the car back on the road fairly quickly — wouldn't hesitate to go this way again. Thanks guys.

As advertised, perfect fitment. Awesome warranty, delivered in 2 days. Somehow it was cheaper and easier to get this new crate engine supplied and delivered than it was to source a second-hand engine. Have recommended to others.

Bought a crate motor for my Hyundai i30 — so far done 30,000km and it hasn't skipped a beat. Would buy again if I needed to.

Very easy to order and get sent straight to my house. When it arrived there was no damage to the packaging and it was very secure on the crate. Definitely recommend if you're looking for a new crate engine.

Byron is exactly who you want to deal with. Straight talker, no nonsense, and always upfront about what's possible and what it'll cost. Couldn't recommend him more.

Representative 4-cylinder image. The supplied crankshaft’s design depends on the confirmed engine and part number.

01 / Match the right version

Engine identification & fitment.

This listing uses the following engine references. Engine code alone does not establish compatibility: build date, vehicle or equipment specification and the original crankshaft all need to match.

Engine reference Engine / version to confirm
N20B20 BMW N20B20 2.0L turbo
Crankshaft reference 11 21 7 640 165 (11217640165)
Condition / supply Brand new / crankshaft only

Before ordering, send your VIN or equipment serial number, engine code, build date, original part number and clear photographs. Reference numbers identify the application; they do not establish genuine manufacturer branding or universal interchangeability.

02 / What you are buying

A new crankshaft for your rebuild.

Crankshaft supply

One brand-new replacement crankshaft in the confirmed specification. This component listing is separate from our complete engine and long motor range.

Plan the remaining parts

Confirm bearings, thrust components, seals, bolts and any gears or trigger components with your engine builder. These items and installation labour are not listed as included.

03 / Prepare for installation

Check the details before assembly.

Have a qualified engine builder compare the journal diameters, stroke, thrust location, nose, rear flange and sensor or trigger arrangement with the original crankshaft. Confirm bearing selection and clearances using the correct engine specifications.

Investigate the original failure and inspect the lubrication system and related components before fitting. Confirm availability, delivery arrangements and the applicable component warranty with our team before booking the job.

04 / Before you buy

N20B20 crankshaft FAQs.

Is the photo the exact crankshaft I will receive?

The branded image represents a 4-cylinder crankshaft. It is shared across relevant listings; details such as counterweights, journals, nose and flange can differ. Confirm the actual specification with our team.
