1UZFE EGR Delete Kit/JMD Conversion

UPDATED LEXTREME FORUMS - Post Questions Here!

Exhaust gas recirculation (EGR) systems were introduced in the early ’70s to reduce an exhaust emission that was not being cleaned by the other smog controls.

The EGR block-off plates are for the 1990-1994 Lexus LS400 and 1992-1996 SC400.  These plates might work on other 1UZFE Models. These high quality CNC machined mild steel plates will allow you to completely remove the EGR system. These plates were designed by one of our hardcore Lextremers using AutoCad 2004. 

The factory EGR system allows super-heated exhaust gases to re-circulate from the rear of the cylinder head back to the intake manifold. The excessive heat at the rear of the head has been known to be the cause of detonation. I have personally witnessed malfunctioning EGR valves leak and reduce performance and increase exhaust noise.  I also experience cracked EGR pipe and my “check engine” light came on. 

I drove around for a year with my EGR pipe cracked and its a very common problem with Lexus V8 engine.  After I replaced my EGR pipe the “check engine” light was gone and no more exhaust leak and noise.  However, it was expensive.  Replacing the EGR pipe is very expensive in parts and labor.  This kit will simply eliminate these problems. The stock gasket can be re-used from the EGR system. Installation instructions and the proper value resistor (prevents MIL to trigger) are also included. Please note that this modification is not legal for use on any pollution controlled vehicle and cannot be used on a public highway. Off road use only.

The whole package is only $99 dollars.  Here is what u get:
* Exhaust Passenger Side Block Plate
* Intake Exhaust Plate
* Side EGR Block Plate
* Resistor to prevent MIL.
* Two Washers
* Bypass Radiator Hose
* New Vacuum line
* Plug Caps

Here are the benefits:
* Lower Intake Temperature therefore increase HP (2-5 hp estimated)
* Reduce expensive Lexus Parts for repair
* Increase Exhaust flow for Turbo Application
* Cleaner look of your engine bay
* Easier to change Injectors and other parts due to EGR delete.

You can remove the followings:
* Vacuum Pipe
* EGR VSV
* Fuel Pressure VSV
* Accelerator Bracket
* EGR Valve and Vacuum Modulator
* EGR pipe
* Radiator coolant bypass
* Misc. Vacuum lines

Red Brackets above are what you can remove.  Green bracket is the system can be deleted.

This is how it look like after the removals:

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 trill and errors.  There is no cookbook for the 1UZFE modifications and its a virgin territory for performance.  The parts, labor, web development and site hosting are 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 appreciate it!
