Swap AJ200D (D200) with AJ300D (D250, D300) engine on L663
Hello, I own a Defender 90 diesel D200 2.0L (engine AJ200D), however, after owning a V8 car for a long time I still can't get used to the low capacity of my 2.0L L663 engine and looking for ways to improve the performance dramatically (more than just chip-tuning from 199hp to 240hp).

I wanted to know if anyone here on this forum have past experience swapping AJ200D (2.0L, 14, Diesel) with AJ300D (3.0L, 16, Diesel) engines and how complex this process is for L663. From what I heard, unlike the AJ200D, the AJ300D Defenders have an MHEV and I don't know if it complicates the process dramatically.

Please let me know if you guys came across any info about this topic or if you have experience swapping engines. Thanks everyone beforehand!

Sounds like it will be better to sell and get what you want. Confused Eiger Grey MY23 D250 SE with bits. Known as Noddy.

Heavens that would be a massive job. Although anything is possible. ldeally you would need to find a written off Defender with the 3.0 engine still intact.

As above, better to sell yours and buy the one that you want.

hi - i'm thinking of doing exactly this - so did you manage to find someone or do the swap yourself?

Another thing to be aware of is that the 3.0 diesels have the Active Driveline AWD system that replaces the center differential for a clutch pack and a front axle disconnect. Eventually all Defenders got this drivetrain for the 2020.5MY. The engine might not be compatible with the permanent 4WD system in your current Defender, and of course add on the fact that you'd need to retrofit all of the MHEV components. You're honestly better off getting a new Defender. 𝟐𝟎𝟐𝟏 𝐃𝐞𝐟𝐞𝐧𝐝𝐞𝐫 𝟏𝟏𝟎 𝐒 𝐏𝟑𝟎𝟎 (Pangea Green over Acorn/Lunar)

Years ago, I swapped my RR 4,6l V8 engine with a stripped engine from "Turner Engineering" including Heads, with new block, front cover, Oil Pump assembly, etc... But not sure they sale 3.0 ingenium, TBC.
