The Cartune Company (2003) Ltd in New Zealand does 1uz and 3uz conversions / parts and wiring. We have been working on UZ Toyota V8 engines since 2004 when we did our own Hiace van to transport dirtbikes around NZ. Since then we have swapped to doing mainly just Lexus V8 work from a family owned farm hidden away in our paradise , surrounded by the NZ native bush. We sell parts and simple to follow wiring instructions for the 1uzfe engines. For enquiries email info@thecartunecompany.co.nz Take Care. Kelvin
