    LS400 Supercharger Project

    I am begining to drive my car daily now, but not boosting due to a lean Air/fuel ratio. I am confused about whats going on. I plan on rebuilding the M90 and ran my gas talk dry and make sure there is no water in there. Many people have made this work on a stock setup, so it should have no...

    Lex, I have a 1993 LS. So many people have run this without any type of ECU or Fuel upgrade. I at least used a 1:1 FPR. I should have no problems at only 6lbs. Should I regap the plugs??? Where should my fuel pressure be at idle and boost???

    LS400 Supercharger Project

    I have a bone stock setup other then the blower. 6 lbs pulley. AEM wideband. No obvious knocking. Only a hint of white steam from tail pipes, I have changed the valve on the power steering already FYI. The OEM regulator is still there but does not do anything since I have the Aeromotive working...

    LS400 Supercharger Project

    I have everything up and running pretty much as it should. I finally got the boost gauge working and I have found out that as soon as the bypass valve shuts close and the blower starts making boost it just bogs down. I can hear ther blower getting that whine, but it just bogs down, the wideband...

    LS400 Supercharger Project

    I am in the process of putting the exhaust back and rewiring my boost gauge which still does not work. I have to put some RTV gasket on the thermistat pipe because I saw a future leak. No check engine light thus far, just the ECU struggling with the transplant. It did not overheat and the timing...

    LS400 Supercharger Project

    I finally had the balls to turn her on today. She started right up with no difficulties at all. After about a minute of chugging along, the engine would pulse up and down from 600 to about a 1800 every10 seconds. It was the ECU for sure, as unpluging the MAF stopped it right away. I then reset...

    LS400 Supercharger Project

    I just recently received a Richwood Manifold with the rear intake to suit a M90 setup. This is absolutely a solid piece of work. Looks like it was meant to be on the engine from the factory. Nobody else out there can give us better looking craftsmanship and durability. It maybe pricey to some...

    Hey guys, I managed to remove the cam seals pretty easily. My crank seal looks in good shape and I dont want to mess with it fearing that I could reinstall it incorrectly. Thanks for the advice nonetheless.
