In A Blaze Of Glory
The hefty Trailblazer SS is a stout performer for its size, but with the STS Turbo Remote Mount Turbo System, the full-size SUV will have no problem keeping up with tweaked V-8 coupes. Go from 340 wheel horsepower to 430 with only 6 pounds of boost from a TO4E 60-1 that is good for up to 620 ponies. This appropriately sized turbo guarantees great street manners, not to mention 465 lb-ft of torque that will help get the 2.5-ton behemoth moving. Included in the kit is a TiAL 38mm wastegate, all necessary pre-bent piping, mounting hardware, wiring harness, installation manual, and STS's patented oiling system. The deal is sweetened by a one-year warranty.

New To Gen II
Drawing upon its many years in the small-block Chevy market, Dart has created a Platinum Series aluminum cylinder head for LT1/LT4s. These heads were developed using Dart's exclusive wet-flow technology, and will accommodate the Gen II's unique reverse-flow cooling system. Much like the conventional Platinum Series SBC head, the 23-degree LT1/LT4 head has five-angle intake seats, radiused exhaust seats, back-cut stainless steel valves, and a relocated spark plug hole for greater combustion efficiency. The port shapes are optimized and sized at 180/75cc to flow 257/172 cfm at .500-inch lift (with 2.02 and 1.60 valves). These heads are available bare or assembled with your choice of 1.250-inch single valvesprings, 1.437-inch double valvesprings (for higher-lift hydraulic roller cams), or 1.550-inch double valvesprings (for solid rollers).
