Stage 5 kits are intended for higher HP goals. Mandrel bent stainless steel crossover and downpipe will hold up under the most demanding conditions. Kits comes with a 88mm turbo, standard. Good for 1100HP to the ground. Thick wall swept runner turbo manifold, uses 3/8" flanges that are TIG welded. This gives the best looking welds and great heat control during the welding process. 44mm waste gate keeps the boost under controll. Standard waste gate configuration is vented to the atmosphere. This allows you to hear when the gate is open. The aluminum cold piping is painted black for that OEM look. With bead rolled ends these cold pipes will not leak or come apart; even under the highest boost demands. The intercooler is our Stage 5 intercooler core with 3.0 " inlet and outlets.Mounts directly to the frame using our universal brackets. 2.5" / 3.0" cold piping from turbo to the IC depending on applicaiton. After the intercooler the piping starts to increase is size up to 3.5", making the transition to the throttle body clean and seemless. 60mm blow off keeps away the turbo surge sound, and it just sounds cool. Releasing all the boosted air from turbo to throttle when you lift off the throttle. The blowoff protects the turbos for turbo surge and protect the throttle body from having boost pushing on a closed throttle blade. HI boost pressure with out a blowoff can result in damage to your turbo and throttle body blade or shaft.

Picture is shown with waste gate venting back into the downpipe. This is not standard for this kit. Picture is a STAGE 5 kit for a Tahoe, some items will be different for other vehicles.
