Future Fab Nissan SR20DET V-Band Top Mount Manifold

The Future Fabrication SR20DET V-band top mount manifold is a made in the USA turbo manifold for the S13 and S14 240SX with the SR20DET, built from thick wall 1 1/4 inch schedule 40 stainless steel runners that are fully TIG welded and back purged. It carries a lifetime warranty to the original buyer. The V-band turbine inlet flange suits Tial, Garrett and Precision style GT28, GT30 and GT35 exhaust housings, and you choose between a 38mm MV-S or 44mm MV-R wastegate flange when ordering.

Construction

• Thick walled 1 1/4 inch SCH40 stainless steel runners
• Fully TIG welded and back purged for clean internal welds
• V-band turbo flange for Tial, Garrett and Precision GT28, GT30 and GT35 exhaust housings
• Wastegate flange option: 38mm MV-S or 44mm MV-R
• Made in the USA
• Lifetime warranty to the original buyer

Schedule 40 pipe is heavier than tube but far more tolerant of heat cycling and cracking, which is why serious SR20DET builds favor it for a top mount manifold. Back purging the welds keeps the inside of the runners free of oxidation and sugaring, which protects flow and weld strength.

Chassis fitment

• LHD S13/S14, with or without ABS: manifold clears power steering, AC lines and brake lines with either wastegate option
• RHD S13/S14 without ABS: clears power steering, AC lines and brake lines with either wastegate option
• RHD S13/S14 with ABS: clears power steering, AC lines and brake lines only with the 38mm wastegate option

Ordering

Select your wastegate flange size at checkout and match it to the wastegate you plan to run. RHD cars with ABS must order the 38mm MV-S flange.
