S15 Plumbing Project

Sick of S Chassis yet? Me neither…. In fact these cars are becoming extremely sought after and I cant think of a better platform than an S15 Silvia to build as a race car. Recently a friend reached out to me to complete some work on this car and I thought it would fit nicely on the Projects page and it would reiterate the Skills I teach in the courses.

In this project HERE we complete the Intercooler plumbing on this S15 Silvia that has recently received a complete Tomei Genisis SR20 engine and turbo upgrade.

In Part 1 we build the intercooler plumbing out of 6061 aluminium 3″ tube utilising Vibrant couplers and simplify the engine bay layout by adding 3″ cast aluminium bends to each side of the intercoolers end tanks. During this Part 1 video we run through all the tips and tricks to maintaining the cleanliness of the aluminium during fabrication which leads to nicer welds during the finishing stages.

In Part 2 we move to the backside of the turbocharger and fabricate a 3.5″ stainless steel dump pipe that incorporates the provision to plumb the twin Turbosmart wastegates back into the exhaust system which switches to titanium and exits out the back of the car in a light, free flowing exhaust system.

Part 3 is coming soon, in this we setup the TIG welder for Titanium as we tackle the intake pipe and create a nice bespoke lobster back intake that feeds clean and cool air from the air filter into the turbo charger.

It’s not the only work we will be completing on this car but I will keep you updated as the build unfolds and we add new parts for you to watch.

Thanks for watching.
