The Singer Vehicle Design‘s Porsche 911 Engine Upgrade includes the following main parts for the naturally aspirated engine: Cylinder heads, pistons, cylinders, crankshaft, throttle bodies, fuel rails, high flow injectors, camshaft, connecting rods, 2 Car Sound 3—Way catalytic converters, p/n 456205, a pair of 3 into 1 16 gauge headers, oil cooler, fuel pump, new fuel tank (same capacity as stock), fuel lines, new manual transmission, open element air cleaner, and a new ECU with no user adjustments. Stock components that are retained are the engine block and intake manifold. Overall displacement is increased from a 3.6L to a 3.8L. Vehicles originally equipped with a turbo and intercooler must have these part removed, and are not transferred to Singer Vehicle Design‘s Porsche 911 Engine Upgrade. This Executive Order is valid provided that the installation instructions for the Porsche 911 Engine Upgrade will not recommend tuning the vehicle to specifications different from those of Singer Vehicle Design. Changes made to the design or operating conditions of the Porsche 911 Engine Upgrade, as exempt by the Air Resources Board, which adversely affect the performance of the vehicle‘s pollution control system shall invalidate this Executive Order. This exemption is issued based on submitted emissions test data, from Automotive Testing and Development Services, Inc., Ontario, California, on a 1990 model year Porsche 911 certified to the Tier 0 emission standards and tested using the Cold Start Federal Test Procedure (FTP) test cycle and a Diurnal Heat Build + Hot Soak:

This Executive Order is also based on the On—Board Diagnostic I (OBD 1) testing conducted on the same test vehicle. The Porsche 911 Engine Upgrade when installed on the test vehicle did not affect the vehicle‘s ability to perform its OBD I monitoring. The Air Resources Board reserves the right in the future to review this Executive Order and the exemption provided herein to assure that the exempted add—on or modified part continues to meet the standards and procedures of Title 13, California Code of Regulations, Section 2222, et seq.
