    T4 Exhaust Manifold with External wastegate

    You know Matt, the reason they are cracking down is because guys insist on removing the CAT or insist on running an open waste gate or insist on removing the EGR or clean up the engine bay by removing the charcoal canister. I've lost count of the threads that are asking how to do any (and more)...

    New Engine Set-Up Finally In *PICS*

    I'm not Jake, but you are absolutely correct...this kind of BS does not belong here. I cleaned the thread up. No more nut swinging, no more BS games. The bottom line is Bill spent a bunch of cash on a block that's not going to work. Basically a re-do...so for you central FL boys, if you got...

    Vegas!!!! MK3's smack Talk/update on travellers heading to Vegas

    ^^^ You didn't answer the question...just said the same thing again. Let me rephrase, how does a manual tranny transmit less shock to the drive train? I'd like to hear this one ;)

    CODE 71...help anyone?

    The two VSV's are the same...the forward one on the manifold is the high temp fuel pressure up VSV. It is vented to the atmosphere when 12 volt power is applied (from the ECU) to it: http://www.cygnusx1.net/supra/Library/TSRM/MK3/manual.aspx?S=FI&P=116 The EGR VSV is mounted on the rear of...

    Vegas!!!! MK3's smack Talk/update on travellers heading to Vegas

    I agree about being easier on the wallet, but how do you get "easier on the rest of the drivetrain"?

    That's one of the potential problem areas listed in the TSRM ;)

    FFIM and EGR valve???

    Good luck routing the pipe under...I tried to figure out a way to do that and it just didn't make sense with the way the EGR valve sits on the head and the outlet to the plenum is positioned. Remember to apply the KISS principle ;)

    CODE 71...help anyone?

    It's the ECU...the sensor simply provides input to the CA ECU (labeled THG). The code can also indicate a problem with the EGR VSV or it's circuit....again, only on CA cars. I tried to find the temp threshold that triggers the ECU, but no luck.

    CODE 71...help anyone?

    Code 71 is only on CA cars...if the sensor is not hooked up (or if there's a circuit problem), it will throw a code on those cars. The other reason is EGT gas temps are below a certain level...the real reason the code 71 is programmed on a CA car ;)

    Lexus LS400 AFM Capacity and Limits on 7m

    Bounty is correct...the screw affects the amount of unmetered air entering the system. More unmetered air means you can attain higher boost before you hit fuel cut. Keep in mind the AFM looks at air intake volume and fuel cut is based on that volume. It also will affect AFR to an extent, more...

    Faulty EGR Valve

    You need to pull the ECU codes before you start chasing your tail. Are you sure you set timing correctly after changing the CPS? (hint - the diag block must be jumped) It's very unlikely the EGR is causing your idle rpm to "jump".

    EGR removal...help?

    Before you remove that "POS EGR valve" that the "idiots" that designed this motor tuned the USDM ECU to run with it installed, you might want to read this: EGR Effect on EGT To answer your question, the correct way to remove it so your car can spew one of the most noxious pollutants a car...

    Faulty EGR Valve

    LOL...for CA cars, yes that's true.

    I'm changing my timing belt and this is what I found. What does it indicate?

    Only one problem...the crank pulley (dampner) has rubber in it ;) Plus, I wouldn't re-use that bolt.

    Faulty EGR Valve

    Other than not passing emissions...a crappy, rough idle.

    AFPR hose diameter to the Fuel Rail

    The purpose of the return line (through the AFPR) is to return fuel to the tank the engine does not use. The FRP is an intentional restriction in this line to control pressure in the rail....the J-tube is there on the stock set-up to provide a restriction in case the FPR fails and keep the...
