Tuned Port Injected (TPI) engines with Vortec heads are a reality, thanks to the Chevrolet Performance team. Their engine dynometer tests have shown a 40 hp gain with the new Vortec TPI base plate and stock Vortec heads versus the stock L98 engine. The Vortec TPI base manifold was designed from the original GM TPI intake to be a universal fit for Chevrolet/Pontiac cars (1985-92) that were equipped with factory Tuned Port Fuel Injection—and the cylinder heads have been replaced with the new style raised-port improved flowing Vortec heads from Chevrolet Performance. * Performance gains: In-house testing has proven a gain of 40 hp over a stock L98 engine. The larger runners of the TPI Vortec baseplate, combined with the excellent flow characteristics of the GM Vortec heads, produced 300 hp on an otherwise stock L98 engine. Other modifications such as camshafts, rocker arms, and injectors produced as much as 375 hp with the stock computer and throttle body. Testing was performed with a mass airflow (MAF) sensor system. * Minor modifications required: TPI Vortec baseplates are a universal design that we patterned after the original GM TPI baseplate. Because it is a universal design, you should first test fit all components that bolt directly to the intake and make any required modification prior to final installation. Some modifications may be required of the external components related to the intake and EGR systems.

FAST LSXRT intake manifolds are designed specifically for GM truck engines (4.8L, 5.3L, and 6.0L) and LS1, LS2, and LS6 race applications where hood clearance is not a concern. FAST LSXRT 102mm intake manifolds follow the path chartered by the original FAST LSX Gen III intakes by featuring a modular design that allows for easy porting and disassembly and a runner design that yields an incredible 25 peak horsepower gain over the stock intake (on a stock 6.0L engine with a Big Mouth 102mm throttle body). Similar to the LSXR 102mm intake manifold for cars, the LSXRT features the ability to remove individual runners for modification. LSXRT's are constructed from a proprietary precision injection molded polymer which offers many benefits, including lighter weight, greater strength and lower heat soak propensity. While they feature a 102mm air inlet that was designed for the FAST Big Mouth 102mm throttle body, they can also be used with stock 90mm or aftermarket 92mm throttle bodies (78mm three-bolt throttle bodies require an adapter). Other features include integrated nitrous bungs and precise bolt-on fit that permits the use of factory accessories and OEM fuel/emission connections without adjustments or clearance issues. Some GM truck models may require the FAST 92mm or 102mm throttle body.

Holley EFI LS Hi-Ram intake manifold bases are cost-effective alternatives to fabricated sheet metal for high performance applications where induction system height is not limited. Coupling these cast aluminum Hi-Rams with the high flowing LS-style cylinder heads has outstanding potential for N/A and forced induction applications at a budget-minded cost. These modular lower manifolds accept a wide range of carbureted and EFI tops, making them attractive to builders and fabricators as the perfect foundations for custom induction systems. Fuel rails are included and machined for -8 AN O-ring fittings with passages large enough to accommodate high fuel flows and dampen pressure pulsations in the fuel system. The aggressive, bold, race-bred styling of Holley GM LS modular Hi-Ram lower manifolds will make bad intentions clear for drag race, muscle car, marine, off-road, sand rails, pulling trucks, track, and street-rod applications.
