Turbo Log Header Build Kit: Nissan RB25 Side-Mount Turbo Manifold

Everything you need to finally build your own custom turbo log manifolds. 100% American made materials, with all tubing and mandrel bends constructed with 0.120" heavy wall 304SS tubing.

These flanges are specifically designed to fit the RB25DET cylinder heads. They may also fit aftermarket cylinder head designs with the same bolt pattern

Complete kits built from 100% USA made materials with the finest quality available, all in thicker-than-standard tubing & flange choices, specifically to withstand the increased pressures and heat found within any turbocharged exhaust system.

The base kit will include the following:

Contents:

• (1) 1/2" Thick, 304SS, 1 1/2" Port RB25DET Turbo Flanges (Primaries must be welded to top surface of flange)
  
• (4) 2" OD x 0.120" Heavy Wall, 75 Degree 304SS Mandrel Bends
• (2) 2" OD x 0.120" Heavy Wall, 90 Degree 304SS Mandrel Bends
• (2) 2" to 2 1/2" x 0.120" 304SS Transitions
• (1) 30" Lengths of 2 1/2" x 0.120" 304SS Tubing
• (1) T3/T4/T6 Turbo Inlet Flange (Open and Divided housings available)
  
• (5) Purge Caps
• (1) 1/2lb of 1/16" 308L TIG Filler Rod

Upgrades:

• "Power-Size Upgrade": Upgrade to a larger 3" Diameter Log for increased airflow in high-power applications. The accompanying vbands are also upgraded to 3" diameter. Any successive elbows for your application will then be built from 3" x 0.120" material as well. (Note: This will disqualify the use of any T3 turbo elbows, as 3" is too large for T3 inlets)
  

We have not yet found the horsepower limit on either the 2 1/2" or 3" log systems- so throw everything your turbos have at these! With all American-Made 304 stainless steel, these turbo log header build kits are perfect for any tight-clearance or limited engine bay configuration. Quick and easier to build than a standard tubular header, and with parts off-the-shelf, you no longer have the expected lead times on having us build your modular turbo headers for you

Best part? With our v-bands made in the USA, and standard on these kits and all of our turbo elbows, we can supply your build with more of those modular elbows we've been producing for years.
