Why Choose the Nexus Rebel JZ?

Instead of piecing together a JZ swap from a dozen separate parts, the Rebel JZ is engineered as one cohesive kit — ECU, harness, sensors and adaptors all designed to work together from day one. That means fewer compatibility questions, a faster install, and a tuning-ready platform backed by Haltech's NSP software and support network.

Frequently Asked Questions

Does this support automatic transmissions?
No, the Rebel JZ kit supports manual transmissions only, with a harness suited to the R154 gearbox.

Do I need to buy anything separately?
The core kit includes everything needed for the engine and transmission side. The R35 coil conversion kit (HT-120200) is sold separately if your engine doesn't already run R35 coils.

Can I tune it wirelessly?
Yes, the Nexus platform supports Wi-Fi connectivity for tuning and monitoring via the Haltech Connect App and NSP software.

Will it support a twin turbo setup?
Sequential twin turbo setups are not supported. Single turbo and twin-parallel configurations are supported.
