As of 09/01/18, due to the age and limited availability of suitable donor powertrains of the older 1KZTE engines, Diesel Toys™ is no longer offering 1KZT-E conversions moving forward. This, coupled with the fact that the 1KD-FTV D-4D is such a far superior powertrain to the older 1KZTE engines both in terms of performance and economy, we feel its a no-brainer. When customers are wanting to upgrade their older Tacomas, we feel that the D-4D is the overwhelmingly better choice for these trucks.
