After many requests we have designed a custom engineered oil drain line kit for Boport  top mount headers. Included is everything you need to connect from your turbo to the block. Provides ample clearance and proper flow of oil. High heat coated black PTFE lined hose is rated for high heat. For added protection we also include fire braid heat sleeve. Requires re-clocking the turbos center section. Please select turbo type so we send the correct flange for your turbo.
