No it will not work on the GTS. For the GTS you will want to look into the blitz supercharger or the procharger sc.
""Universal Sport Compact Kit (fabrication and tuning required). The Universal Sport Compact Kit contains the C-1 ProCharger, 2 core compact sheet metal intercooler, universal tubing kit, right-hand or left-hand universal supercharger bracket, a Bosch surge/bypass system, and an air filter. Optional items include ProPump fuel pump assembly, FMU assembly, and a 3 core compact sheet metal intercooler". HO 2 Core Intercooled System with C-1 Procharger is $3,396
(Universal kit options)
Polished finish for Procharger (7" housing) $210.00
3 Core Intercooler System Upgrade $310.00
Polished finish for 2 Core Intercooler $135.00
Polished finish for 3 Core Intercooler $160.00"
So figure 3400 for the procharger, 550 for the emanage w/ necessary harnesses, and about 1000-1500 for installation and tuning. So for 4950-5450 you can without doing any research say 80 whp and have the reliability of a supercharger. http://www.procharger.com/SPORT_COMP..._compact.shtml
