Comparing 2JZGTE Valve Spec Vs. 1UZFE Valve Specs

UPDATE: A limited supply of the original best-selling Lextreme 1UZFE EGR Delete Kit is available for sale. 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.

Please note: we're not an auto parts supplier and I can't respond to inquries for random Lexus and Toyota auto parts. All parts not listed above, including the LS400 and SC400 turbo kit, rebuild kits and supercharger are sold out and won't return. The Lextreme performance torque converter has a very long waiting list. Email me if interested.

This is a freelance site with no support by huge companies.  I have been doing most of the R&D and technical write-ups by myself with my personal money and literally thousands of hours of my time.  I have taken extra steps to demonstrate in details how things are done.  Currently I am one of the few people doing Lexus V8 research and performance enhancement.  This effort comes from my personal love for this wonderful engine.  Most of the modifications are from trial and error. There's no cookbook for 1UZFE mods and its unknown territory for much of supercharger performance.  The parts, labor, web development and site hosting are 100% paid from my personal hobby money.  If you feel my efforts help you in any form, please do not hesitate to donate any amount of money to support this site. You have no idea how much I and the entire Lexus and Toyota community appreciate it!
