looking to build a twin turbo setup what would i need looking to go with a s 300 and s 400

 

Hot pipe, cold pipe, s400 mount, 5" downpipe for s400, a "y" style oil drain or weld a bung in oil pan for 2nd oil return, s400 intake

If your truck is auto you will most likely need to relocate the trans heat exchanger

i also have a few twin parts, PM me if interested.

 

would i need to head stud it

 

yep
here is my twins i just did'
