LEXUS 1UZFE MODS FORUMS - Post Questions Here For Quick Answers!
Do you have any questions? If so, please head over to the forums to get a quick answer or share your experience!
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!
