Demo tool - try XE with AJ200D or F‑PACE with AJ126 to see sample results. Production version covers all Jaguar models and engines.
Choose your current or intended Jaguar model from the dropdown. If you're unsure, use our registration lookup to identify the exact chassis.
Choose the engine you're considering - whether for a swap, a replacement, or a conversion project. We support the most common Jaguar engines.
We tell you if the engine is a direct fit, requires modifications, or is not recommended. We also suggest alternatives and link to detailed fitment guides.
This is one of eight free tools on the site - see also our engine value checker, repair vs replace calculator and registration lookup.
Direct fit - the engine was offered in that model from the factory; no major modifications are required. With modifications - the engine may fit but requires changes to mounts, ECU, cooling, or exhaust; we note the main challenges. Not recommended - the engine is not a practical fit; we suggest alternatives. All verdicts are based on real fitment data and specialist feedback [THIRD‑PARTY].
For a complete list of every engine ever fitted to each Jaguar model, see our Fitment Matrix. For engine‑specific details, visit the Engine Knowledge Centre.
Compatibility data is sourced from Jaguar factory technical publications, independent specialist workshops, and cross‑referenced with our own 2025 enquiry database [EM‑VERIFIED]. Where we lack definitive data, we mark the result as Uncertain and recommend consulting a specialist. Full methodology on our Data Methodology page.

We use the best available data, but conversions can be complex. We always note if modifications are needed or if the result is uncertain - and we recommend professional advice for any engine swap.
We cover the most common Jaguar models and engines. If yours is missing, use our Engine Code Guide to identify the correct family, or contact us via the contact page.
Some engines are shared across JLR (e.g., 306DT, 276DT). Our tool includes shared engines where they were factory‑fitted. For non‑factory swaps, the verdict will reflect the challenges and point you to specialist advice.
