Although we supply you with vacuum tubing for your wastegates it is your responsibility to route them so they don't melt.  Routing the vacuum tubing correctly requires you to possibly disassemble your wastegates and point the inlet/outlet in the right direction.  Routing your vacuum lines too close to your exahust will result in melted vacuum lines which could result in overboost/underboost. 

Presenting our latest kit tailored for G Series S58 powered M cars. In collaboration with industry leaders Precision Turbo and Turbosmart, we are proud to offer what we believe is the most comprehensive kit available. The kit commences with an in-house handcrafted turbo manifold featuring substantial 1.90" OD runners, capable of facilitating over 1500hp flow. Employing Precision Turbo's Next Gen Turbos, engineered for optimal power generation with minimal lag, our Next Gen 6466 ball bearing turbo effortlessly achieves 900whp while maintaining a spool comparable to stock turbos. Turbosmart provides the two 45mm Gen V wastegates included in the kit. We meticulously fabricate 3" charge pipes in close proximity to the engine, ensuring steadfast placement with a welded bracket. Additionally, a heat shield is incorporated to safeguard your fuel line from heat exposure. The kit features a 3.5" stainless downpipe that splits into dual 3" outlets, seamlessly connecting to the factory exhaust. To finish the system, dual 1 3/4" stainless dump tubes exit to the atmosphere at the rear.

Some features about our kit worth noting:

• We include a heat shield to protect the oem fuel line and the valve cover.  With as much heat generated with any single turbo kit we didn't want to take any chances.  The kit includes a stainless steal heat shield and serves as an extra layer of protection for your fuel line and valve cover. 
• Oil drain line is made of aluminum hard line.  Others in the industry include fittings and rubber hose that you have to cut and assemble yourself.  Cutting to wrong length could end up melting the line.  Included with this kit is a pre assembled hard line with no guessing. 
• Our charge pipe has a bracket that bolts to the engine so it will never move over time.  The S58 motor requires that you run a charge pipe close in front of the engine balancer.  To eliminate risk of it hitting the balancer over time we fabricated a bracket to bolt to the engine just like how's it done from the factory.  Without this feature you risk the charge pipe hitting your engine balancer. 
• We included a printed installation manual that will instruct you how to install this kit from start to finish.  
• Our cnc fittings (oil drain, oil drain block off, oil feed, oil feed block off, PCV) are fitted with o-rings.  Other companies require you to use your used factory o-rings!
