What is it? SRP Pistons
Why You Need It: These new-design pistons feature a high-silicon, 4032-aluminum, F.S.R. forging and are up to 100 grams lighter than competitive offerings. They are designed for naturally-aspirated or moderately-boosted street-and-strip applications. The piston offers a 29cc inverted dome and is manufactured using a dedicated forging specific to the LS family of GM engines. If you are a sportsman or street-based performance enthusiast, you'll find this piston kit offers a low 9:1 compression ratio and is a great choice for stroker motors with a 4.00 stroke.

What is it? StreetFighter 10-Inch LS1-to-GM Turbo 350/Turbo 400 Torque Converter
Why You Need It: LS1 and LS2 racers have often complained of overpowering the 4L60E computer-controlled GM transmission in their Firebirds and GTOs. This product follows a trend of allowing racers to go back to their roots and connect a Turbo 400 or Turbo 350 directly to the bolt pattern and pilot of the LS1 and LS2. The benefits are increased strength, no computer interaction, and greatly reduced transmission repair and replacement costs. Stall speeds of 3,000-3,500 rpm are offered, and custom stall-speed units are built for the customer by the manufacturer.
Applications: '98-'02 and '04 LS1, '05-'06 LS2
MSRP: $569

Applications: '98-'02 and '04 LS1, '05-'06 LS2
MSRP: $1,399-1,999
