Can I put a 4BT engine in my Jeep YJ?
Yes. We sell conversion kits that fit the 4BT into the Jeep YJ. The kit replaces the 300Tdi, 4.0 and 2.5, and works with the AX15, R380 and NV3550.
You can buy the full package with an engine, or only the parts you need: complete conversion with engine, complete conversion, adapter plate, engine mount, wiring and ecu and cooling and exhaust.
A swap like this needs a skilled workshop. Mounts, the adapter, the wiring and the engine computer, the cooling and the exhaust all have to work together. Check your local road rules for engine swaps before you start.
Tell us your Jeep YJ's year and current set-up, and we suggest the right parts. You can reach the Hamburg desk by email at autowerkeengines@gmail.com, or by phone and WhatsApp on +49 15510 030835, Monday to Friday, 9:00 to 16:00 CET.
