Project STurdteen, Plumbing the Motor and Getting Her Ready to Run!

You can see the 4 polyester plys here.  Most lower quality hose is only two-ply.

We also used HPS silicone vacuum hose.  It is tougher and much more temperature resistant than the typical rubber vacuum line.

We used the HPS vacuum line for the turbo wastegate to the AEM Electronics boost control solenoid. Since our S13 will be running an Infinity 5, this combo will give us many performance and safety options that we can program in. We also used HPS vacuum line for the MAP sensor and fuel pressure regulator.

We used -8 Earls Autoflex hose to fix the engine venting. We fabricated a stainless hard line from the block vent over to the valve cover vent.  We used a hard line as this vent tube needs to pass near the hot turbo manifold.

Dash -8 Autoflex hose runs from both valve cover vents over to the catch can.  Now all 3 engine crankcase vents are functional. Crankcase pressure will not be an issue anymore.

The crank vents lead to the Canton Racing Products catch can that has a breather filter. The catch can has a handy drain for any oil that may end up here.
