Modular Turbo Headers- Big Block Chevy Single Turbo

Designed to fit the 4.84" bore space big block chevy heads, these bolt-on turbo headers are the perfect solution to any turbo header packaging concerns. They fit all aftermarket applications utilizing the stock 4.84" bore space. Made of heavy wall, American Made stainless steel pipe, these modular log manifolds can handle the heat and vibrations that come from a turbocharged engine build.

The beauty behind this design? The builder never has to touch a tig welder or strike an arc. Every component can be bolted and pieced together in a modular fashion, without every worrying about the strength or quality of the builder's welds and fabrication. The compact design also allows use of these modular turbo headers in small engine bays. The heavy wall construction of these manifolds means less heat-absorption by the tubing, which means less energy produced by the engine's combustion process is wasted as heat, and is instead conserved as energy and velocity going to your turbos. This also leads to cooler engine bay temperatures, which can also improve intake air temps, increasing the density of oxygen in the air, leading to further power gains.

This single turbo header design is perfect for creating a crossover underneath the oil pan or bellhousing, and merging to a 3" log on the passenger side for increased flow volume.

This set up will clear stock starters and bellhousings.

We recommend builders start off with the base manifolds prior to adding in the additional elbows to meet your turbo mount points.

The initial set up will come with:

(2) 1/2" thick 304 SS BBC header flanges with a 2" round port in the header flange.

(8) Purge Tig Welded primaries coped into a compound manifold, made of 0.120" heavy wall pipe, 304 SS.

(2) Compound log manifolds with a 2 1/2" outside diameter, kept tight against the engine block for tight engine bay applications, ending with a 2 1/2" v-band flange for additional modular components

Optional Crossover Kits Include the following (all 304ss, 16ga material):

(4) 90 Degree Mandrel Bends
(2) 2ft Lengths straight tubing
(1) Double Slip Joint
(1) Transition (i.e. 2.5" to 3", crossover to secondary log size)

Additional Modular Components available:

• 22 Degree Mandrel bend with accompanying V-band Flanges
• 45 Degree Mandrel bend with accompanying V-band Flanges

We also offer custom y-pipe and crossover tube configurations for single turbo applications, or single exhaust builds.

Using our downpipe mockup kit, we can configure custom downpipe and wastegate dump set ups for fender exit, hood exit, axle dump, or even full length exhaust systems. Bring us your custom turbo header needs.

Not seeing what you need? Not a problem- We can custom build turbo elbows to fit your turbo header needs.
