The owner of this first generation Toyota Tacoma wanted more power than the factory 2.7 L 3RZ-FE inline-four produced. He considered using a LS1, SBC, and even turbo 3VZ V6 but disliked certain aspects of each choice. It wasn’t until he stumbled across Lextreme and its forum that he settled on using the mighty 1UZ-FE V8. The engine was installed using custom mounts, custom intake, SC400 ignitors, modified LS400 wiring harness, and controlled by an Adaptronic ECU. The factory W59 five-speed automatic transmission was mated to the V8 thanks to a modified bellhousing. It was upgraded with a QMI hydraulic throwout bearing, OS Giken flywheel and clutch. This allowed the truck keep the transfer case and 4WD. For more photos and details please read the build thread.
