This is a clean slate, all new setup. Cyl 1-6 use long radius bends and we are using 321 SS material to manage heat better in a road course environment. The collector is aerospace grade quality investment cast stainless steel. 

This kit maintains a twin scroll design while using a single straight gate 50mm wastegate that is fully divided into a 2-1 flange. This keeps cyl1-3 and 4-6 exhaust gas pulses fully divided. The twin scroll advantage is proven and offers faster spool up characteristics and response time over a single wastegate V band design turbo kit.  

The charge pipe is an o-ring v-band connection to eliminate the possibility of any silicone connection failures. The custom heat shield guards the valve cover and the rest of the charge pipe system from radiant heat and will help significantly drop IATs.

The downpipe is a 4inch turbo back with a 3.5 v band exit flange. This can be ordered in a 4in exit as well. This kit uses a custom chromoly motor mount. With this we are able to only use one bend in the downpipe. The result? More flow. This kit is based around the Garrett G42-1200c. it utilizes a 73/91 comp wheel and 82/75 turbine.


The ETA on your custom kit will be 6-8 weeks. We will stay in touch along the way with updates. We will send a pdf with instructions and tips on install. No subframe removal required!
