FAQ

Will the 171702 bolt to my factory manifold?
No. It uses a divided T6 inlet. Most light-duty factory turbos are T3/T4. You’ll need a T6 manifold and matching downpipe.

Is this a street-friendly single?
It can be on the right build, but expect later spool than smaller frames. It shines as a big-power single or as the atmospheric in compounds.

What are the inlet/outlet sizes?
5.0" compressor inlet, V-band compressor outlet, Half-Marmon turbine outlet.

Do I need an oil restrictor?
Generally not for journal-bearing S400 units. Use a clean, appropriately sized feed and a free-draining return; always verify oil pressure on your application.
