The ScienceofSpeed Oil Feed & Oil Pressure Adaptor is designed to allow installation of oil feed fittings (for engine oil lubricated superchargers or turbochargers) or oil pressure sensors to the NSX engine. This fitting eliminates the need to use T fittings (which are prone to cracking) off the factory pressure switch location.
The adaptor allows the replacement of a factory drill plug found on both the front and rear cylinder heads. It threads into the factory's unique British taper threaded hole and allows any fitting or sensor with a 1/8" NPT thread (the aftermarket industry standard) to be installed. The fitting has a broached 6mm allen socket for easy installation with a 6mm allen tool. The fitting can be used with fittings and hoses (not included) to feed oil pressure to superchargers and turbochargers, or to allow aftermarket oil pressure sensors to be installed remote mounted off the engine. The location used is fed with constant oil pressure directly from the crankshaft, so it is a reliable and consistent location to feed or measure oil pressure from.
One fitting included. The common location to use the fitting is the rear cylinder head which is most accessible. Two fittings may be used on the front and rear cylinder heads to feed oil and supply a oil pressure sensor, or a twin turbo configuration.
