Turbo Log Header Build Kit: 5" Bore Space BBC Turbo Manifolds

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 5" Bore Space Big Block Chevy-Based cylinder heads. They may also fit a variety of aftermarket 5" bore space heads. **These are NOT compatible with Sonny's 5" Race Heads**

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.

This kit is ONLY available with 2 1/2" primary tubes & 3" log sizes due to port size.

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.
