Won't work for Lexus USA market.
I'm glad to see people taking the steps to produce aftermarket perfomance for the Lexus engines, however, this mod. needs some work before it's ready.
1st = Without the EGR valve attached, it will not work. Intake shown would require ERG valve mod. to utilize it with this manifold setup.
Since EGR are electronically controlled ( USA Lexus 4.0) not vacuum controlled ( non- USA Soarer) you cannot just disgard it as you can on Soarers and expect things to work.
Thus, this setup as shown NOT work for USA Lexus engines. Attempts bypass or remove the EGR on US cars will cause it to run very rich.
Because the EGR in USA cars is electronic, it's tied directly into the cars computer system. Without the feedback from the EGR to enssure proper fuel managment, the cars onboard computer has no way of knowing where its at.
Side note: All attempts I and others have made to modify or bypass The EGR in USA models have proven unsuccessful.
2nd issue: The ports as shown extrude into the manifold. This in addition to the mounting not being centered would cause some bazarre turbulants resulting in very uneven air flow from the charger into the cylinders. People like Edelbrock have spent millions designing and testing this kind of stuff.
Conclusion: Give you an A for effort but it fails in funtionality.
Still needs some serious revisions before it's ready to market to the USA.
