ARP uses a premium grade 8740 alloy that is rated far superior to "aircraft" quality. Each stud is heat-treated, ensuring complete heat penetration, to increase the clamping load up to 200,000 psi. ARP studs are threaded after heat-treat, which gives them 1000% (that's ten times!) better fatigue strength than studs threaded prior to heat-treat. Threading the studs after heat-treating is more difficult and costly (as it's harder on tooling) but the results are well worth the effort. These simply are the best head studs we've found and we highly recommend them in both racing and forced induction applications. Due to the additional clamping force between the head and block, these are IDEAL for turbocharged engines.

As these cars get older we're seeing more issues with the stock components and more demand for cost-conscious fueling solutions. The new Fuel-It 650HP line of fuel system upgrades are designed with those needs in mind while maintaining a budget. They make the most of the stock components to maintain stock reliability and drive-ability but when the boost gets cranked up, the Fuel-it 650HP components kick in to support the additional fueling needs of your high horsepower car. With the Fuel-It 650HP lineup, you can upgrade your components all at one time or upgrade them as time and budget allows. If upgrading one component at a time, we'd recommend starting with the LPFP first as that is the heart of your fuel system, without a good Low Pressure Fuel pump (LPFP) you can't supply the fuel needed to any of your other components. Your secondary pump can NOT run full time, it must only be run under boost only. Running it full time will place additional strain on the stock system, will lead to high fuel temps, and pump or component failure. To turn the secondary pump on under boost we recommend running the included 4psi Hobb's switch. Included with all S65 LPFP upgrades: Walbro 450 pump (F90000274) Black Anodized Custom fitting Pump brackets 9/64" terminals and associated hardware Fuel line Replacement PITA clip Wiring harness
