U will get the most power and esp torque out of a turbo kit it only works under load which means u can be running big gears on the hwy pulling 3000 rpm and not pulling boost where a charger will. U can also turn the boost to almost nothing for day to day driving. But the turbo is like 5000K. U will need to get a tubular k-member 800$ for the whole kit from UPR I think. A procharger is bolt on comes with a programmer and is around 4000K. But I have been running a NX kit for the past 50,000 miles on a 100 shot with no ill effects. With bolt ons I am running in the mid to low 12's. |
