LSX Composite Intake Manifold

But this manifold has far more potential than just for normally aspirated engines. The FAST folks have also equipped the LSX with integral nitrous bosses that will allow you to easily equip the LSX with individual nitrous injectors for each cylinder. If you'd rather employ a supercharger to stuff additional pressure into the intake, the FAST folks assured us that the LSX intake can handle positive manifold pressures of well in excess of 80 psi! Of course, those optional burst panels are also helpful just in case something unplanned occurs. The internal combustion engineers call those "excess pressure excursions"-we'll just call them hiccups.

Bolting the LSX intake on is a simple remove-and-replace operation, and you might also consider adding a larger, FAST 78mm throttle-body to go with the new intake. If you really want to get serious, you can also obtain an optional manifold that will accommodate up to a larger 90mm throttle-body for maximum performance. The manifold also comes equipped with its own integral rubber seals around all the intake ports as well as the throttle-body so you don't have to worry about installing gaskets. The only real variable has to do with earlier-model LS1 intakes that require a late-model coolant bypass and an oil sending unit. The LSX intake also uses a different PCV valve location compared to the older units, which duplicates the LS6 factory PCV valve modification.

The majority of these manifolds will probably end up on Gen III LS1- and LS6-powered Camaros, Corvettes, and Firebirds. But don't overlook the idea of one of these new intakes on an LS1 (or a 4.8, 5.3, or 6.0L truck engine) in an early musclecar or hot rod. While most of these engines will be controlled by the production computer, FAST also offers a very efficient standalone EFI controller that is fully capable of controlling any Gen III engine. These engines also employ a distributorless ignition system using individual ignition coils for each cylinder. The FAST system offers sequential fuel control as well as timing control for these engines and can also integrate multi-stage nitrous control and/or positive manifold pressures from supercharged/turbocharged applications. The manifold has been tested to withstand positive manifold pressures of up to 80 psi! The only limitation is your own imagination.

Regardless of whether you're new to late-model performance or just new to the performance scene in general, the basic concept around added performance revolves around improving the way air and fuel enter the cylinder. FAST has come up with a way to do that with a high-tech polymer intake that can increase power without adding weight all while looking more like the stock intake. Add up all the features, and it's easy to see that the power is there, just waiting to be used.
