Stainless Steel SR20 Turbo Manifold

Adding or upgrading the turbo on any engine is most likely going to require a custom manifold, or maybe you just want to reposition the turbo in a location that’s not typically catered for in the aftermarket industry? That’s exactly the situation I was in before kicking off this 6 part project producing this SR20 Stainless Steel Turbo Manifold. 

In Part 1 i’ll take you through the materials that I have chosen for the manifold, then we get into the design and fabrication of the all important merge collector.

After that we get into part 2 where we position the turbo and ill show you my personal hack that streamlines the manifold building process and makes this a lot easier than you might think.

In part 3 we take our new turbo position and we produce a JIG, if you’re looking to remake or replicate your manifold then you will want to follow this part of the Project closely, you will be surprised at how cheap and easy it is to make. 

In part 4 we make up the primary tubes, this is an exciting time in the production of the manifold as we can flex some creativity and make our engine bay stand out from the crowd. 

Part 5 is all about welding. Ever wondered how a manifold gets welded up when the tubes are so close to each other, watch this part and find out.

Part 6 completes the finishing touches to the manifold as we give it an internal port and polish, add a turbo support brace and mount it all up to make sure this manifold is ready to handle the HEAT strapped to the side of this fire breathing SR20! 

Clear your schedule for the next hour as we take this 6 part ride to transform a bag of steam pipe bends into a power productive, good looking turbo manifold for this SR20.
