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.

All other parts are SOLD OUT and won't return, including the LS400 and SC400 turbo kit, rebuild kits, supercharger and performace torque converter. We're not an auto parts supplier and I can't respond to inquries for random Lexus and Toyota auto parts.

Lexus-Toyota Oversize Valves

We finally figured out what we need to get those valve into our beloved Toyota and Lexus heads.  Our oversize stainless steel valves are being use by many high performance import cars and they are making mega horsepower with these valves.  These oversize valves are not made for Toyota or Lexus, rather we cross referenced them according to their specifications against our current 1,2 & 3uzfe heads.  These stainless steel valves are machined to match according to customer horsepower goal.  Here is what we are offering:

1UZFE: (1989 – 1997)
Intake: 1.25 mm oversize
Exhaust: 1.5mm oversize

1UZFE VVTi, 2UZFE & 3UZFE: (1998-2006)
Intake: 1mm oversize
Exhaust: 1mm oversize

Depending on cam specifications our oversize stainless valves will machine accordingly.  So every set is custom made according to customer desire in relationship with cam specifications.

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!
