On 3 Performance BMW N54 335i Top Mount Single Turbo V-Band Base Kit is for those that only need the hot-side parts. Below is a list of all the parts listed in this kit. If you want to swap out the turbo or customize the kit, it can be done on our main site.

The turbo provided for this kit is the On3 55mm GT30 journal bearing turbo. The beneficial part of this setup is the exhaust housing is made from stainless steel and has v-band on both the inlet and outlet sides.  With any tight engine bay, this is key to allow for endless adjustments.  This will not only look great but when the install time comes, it will make life that much easier.

The manifold is a custom-designed 2pc setup.  We have designed it from an extremely thick schedule 40 tubings and only use 304ss for the construction.  By making this unique manifold, it allows for a much easier install.  Most of the single top mount kits also require you to modify the factory coolant line as it’s routed through the same area where the factory turbos are.  We took serious attention to detail and built around it so it retains the hard aluminum tubing.  This is not a good area to run rubber hose as some systems do. Our manifold is designed to use ours On 3 Performance 44mm v-banded wastegate to control boost.  Out of the box, your kit will be set up to make around 14psi on wastegate pressure.  Coming out of the wastegate, we have it set up to atmosphere.

Moving the air out of the turbocharger, we designed 3″ downpipes from 304ss.  This will take the gases back to the factory exhaust location and splits into duals.  With each kit, we also include the necessary stainless steel v-band clamps to secure the turbo in place, downpipes as well as the needed clamp for the turbo manifold.
