As I am afraid of water entering the inlet system, I decided to rebuild the turbo inlet pipe. I had initially though of going this route, but as space is tight, I mean really tight, I didn’t do this the first time around.
Since the 90degree pipes I already had didn’t have a sharp enough bend, I had to improvise and create a sharper bend by cutting the 3in pipe in a 45degree angle and weld the two parts together. I suspect this might not be the best solution as air have to pass through the sharp bend just before the turbo, but it’ll have to do for now. I also had to reroute the crankcase ventilation system in order to fit the PVC pressure release valve (which I’m replacing because I suspect it being bad).I reused some of the original piping and rubber bends to route the system close to its original path. This turned out pretty good and actually looks quite nice!
I’m currently waiting for a 3in to 2.75in silicone reduction hose to fit the original mass airflow meter to the 3in intake pipe so I cannot test it quite yet, but it will be nice to hear how it sounds. The previous turbo inlet pipe (first version behind the fog-light) was a bit longer than the original one which resulted in the dump valve being almost inaudible from inside the car.
Since the air inlet is now very close to the exhaust, heat might become an issue. I decided to modify my old heat shield (created from an old computer case) and placed it in between the turbo and the air filter.
I’m attaching some pictures from the build, but remember – I’m not the best welder… Still learning though 🙂
