    Help with turbocharging my SC400 1UZ-FE

    Hi Steve and thank you for posting, I believe that you are right about the boost line,--> it needs to read before the throttle body. I spoke today with a welder that promised to weld a nipple right here: P.S. My gauge is a combined AFR and boost gauge from AEM...

    Boost and Tachometer signal I connected the AEM wideband failsafe gauge today. The AFR reading is working perfectly, however the boost indicator shows weird values; I got the option of showing InHg/PSIg or BAR. It show negative values, something like -20. I connected a T-connector in 2...

    Hi Cribbj, That was my first thought too, however the manufacturer insists that the relays on the board should be good for 2 X 360W. My fans are 14", 12V, 80W. But I agree, 2 extra relays can't hurt, just for the peace of mind. /Mike P.S. Here is the link to the fan controller...

    Tachometer signal The tachometer signal is needed for the AEM Failsafe gauge. I'm guessing it has nothing to do with the function of the AFR reading, but for the graphical display of the logs and the interpretation of the logs. I'm not sure where i can find that signal. As you surely have...

    Hi Steve, Thank you for the advice, the idle got a lot better after I adjusted the pressure to 20 psi. It still needs adjusting by a professional tuner though. I also shredded a serpentine belt while testing. I got 2 small problems and i need advice: 1. The OEM temperature sensor in the...

    Almost there Everything is in place now except for minor details. I bought a new windshield washer tank and installed it on the passenger side. I checked that the fans are working by short-circuiting the temperature sensor connector, they started right away. However, when the temperature...

    Fish-bracket The bracket did touch the frame initially just a little bit, the picture is taken only when we test-fitted. I had to cut a bit of the fender inner-wall, mainly because i want to have that 1/2" clearance. Unfortunately i believe you are right about my motor mounts, maybe it's time...

    Thx, i'll do that. Here is a little update: I did some work today, I installed the fish-bracket and did a mockup of the intercooler pipes, it always turns out you bought the wrong pipe or the wrong silicone tube. I had to replace one of the screws holding the original fan-bracket with a...
