The correct wiring plan depends on the engine, donor ECU, security system, transmission, throttle type and the machine it will power. We plan UZ, GR and UR packages around purpose-built dune buggies, rock crawlers, off-highway safari vehicles, closed-course race cars, boats and custom bikes.
UZ series V8
The UZ family is a proven Toyota and Lexus swap platform with broad workshop experience behind it.
Early non-VVT-i 1UZ wiring is not currently accepted. Every ECU, harness and transmission combination is confirmed before a job is booked.
GR series V6
The GR family offers a lighter Toyota V6 option where packaging and vehicle balance are priorities.
GR scope depends on the exact engine code, ECU, transmission and donor electronics.
UR series V8
The UR family provides modern Toyota and Lexus V8 power with more complex security, fuel-system, CAN and transmission requirements.
UR projects are planned from the complete donor package because requirements vary substantially by platform.
Our custom-application services are not offered for vehicles registered, licensed or intended for street or highway use. That restriction does not by itself authorize changes to regulated systems. Before accepting a project, we review the original engine certification, the finished machine, its intended use and the applicable requirements.
