Welcome to Your Lexus-Toyota 1UZFE V8 Swap/Conversion HQ!

UPDATE: A limited supply of the original best-selling Lextreme 1UZFE EGR Delete Kit remains. If you own a 1UZ from 1990-1997, you really need to get this kit! Email me at [email protected] for help with ordering or questions. This will probably be the last kits I have made.

LEXTREME LEXUS FORUMS HERE! – Post Questions For Quick Answers!

First of all, I just want to say welcome to the top Lexus-Toyota V8 site in the world!  This site is the most complete, most comprehensive and most informative site you’ll find.  We’re the Lexus-Toyota V8 Swap/Conversion capital of the world and your home for Lexus-Toyota V8 Engines. From turbo kits to 1uz superchargers to Toyota Previa minivan engine swaps, we’re here to help!

Our specialized Lexus-Toyota V8 Forum is dedicated to the Lexus-Toyota V8 UZFE family (1UZFE, 2UZFE, 3UZFE) Performance Engines and includes the 2006-2007 V8 powered 4.6 liter Toyota Supra along with the all-new 1URFE, 2URFE and 3URFE engines.

Also, many come here for more information on the GZG-50 Toyota Century 1GZ-FE V12 and how to diagnose a faulty Lexus starter.

Nowhere else on the net will you find so much information about our beloved old school V8.  There are many forums that are car specific.  For example, they will focus on a car model like the Soarer or IS300.  However, in this site we are engine specific.  We focus on the engines, if you have or interest in the Lexus or Toyota V8, then you are in the right place.

Now we also heard the new rumors about the 1ur-fe / 1ur-fse with 4.6 liter. The all new Lexus LS460 will be using the same 4.6 Liter engine. We welcome the new owners and enthusiasts.

Check out this video of a 1975 Corolla Coupe with a V8 engine and subframe from a Lexus SC400, an Eaton M112 Supercharger from a Mustang Cobra, a T56 6-speed gearbox, and tons and tons of one-off performance parts.
