- The chassis of the 964 was derived from the legendary 959 super car
- The 911’s iconic automatic rear spoiler was introduced in this generation, and is still used on modern 911’s. And while it was also the first 911 with optional all-wheel drive, the AWD system added 220lbs to the car
- The engine in the early 964’s intentionally came with no head gasket. While the older 930 Turbos and 3.2 Carrera’s didn’t come with one either, they didn’t carry the oil leak reputation that the 964 did. The design actually worked perfectly fine. However, the bores in those engines were smaller, and sealing pressure across the surface was uniformly higher. Also, the 3.2’s had a 9.2:1 compression, while the 3.6 in these cars were 11.5:1. This meant more force was trying to separate the 3.6 block from its head, increasing the chance of oil seeping through
- The bigger bores on the 3.6 also meant the head studs were further apart, and the mating surface was narrower. After constant exposure to combustion pressure and heat expansion, the heads would begin to “bow” upward from their mating surface, allowing oil to leak through. Left untouched, the leaking oil would eventually “chafe” the cylinders, making the leak worse
- By 1991, Porsche acknowledged the leaking problem, and redesigned the heads, cylinders, and pistons to accommodate head gaskets
- The good news is that ’89 and ’90 cars can be retrofitted. Bad news is that it requires extensive modification (machining the cylinder head, new cylinders, new pistons). The parts alone retail for almost $6,000 new from Porsche, but many buy used to save some coin
- This is the achilles’ heel of an otherwise fantastic 911
- First year of the Carrera 2. The AWD Carrera 4 was the only model available in the previous year (1989)
- First year of the available Tiptronic transmission, as well as the Cabriolet and Targa
- First year of airbags in a 911, as well as the dual mass flywheel
- Dash was redesigned to accommodate optional airbag
- Features a slightly revised engine management system, and onboard diagnostics became an option
- Oil cooler thermostat is revised, as well as the front upper strut mount and wheel hub
- Other small misc changes include updated starter motor, rear spoiler control knob moved to center console (from decklid), front wheel arches and chassis attachments redesigned
- The following year (1991) introduced the first check engine light in a 911, as well as major redesign to the heads and block (which now feature a head gasket)
