The Japan model features the 930 Turbo S/944 style front end with pop up type headlights, 930 style rear quarter vents and boxed rockers. The cars are all LHD, Polar Silver Metallic and feature the exact same build code specification. Four cars were delivered with the 3.8 RS rear spoiler and six with the standard 3.6 Turbo rear spoiler. At ten build the 964 ‘Flatnose’, it is one of the rarest production Porsche’s of all time.
In addition to the “Flatnose type Fenders with front wheel housing vents” the Japan car features the following differences to the ROW and USA cars:
- Air inlet ducts with lands at rear fenders
- XD 7 Tower cross brace (against surcharge)
- Z application 1637 – bucket seats as on 911 Carrera RS
- No backrest and seat belts in rear
- Roof antenna as on model 928

Engine
A key feature of the Flatnose and Package cars was the M64/50 S engine – the X88 “Sport Tuning” option. According to the factory, 155 X88 option engines were built. Ninety-three of these engines went into the “Turbo S” cars, 51 engines were installed in standard 3.6 Turbo models as special order option “X88” and 11 engines are unaccounted for. These were probably sold to customers for race applications such as the Turbo 3.6 IMSA.
The “S” designation is denoted by an understated punch stamp.
The M94/50S engine obtained its increased power from specially modified cylinder heads with different than standard inlet and exhaust ports, upgraded camshafts, modified timing gearwheel and the K27 7006 turbo charger (the K27 7006 has a lager hot side than the K27 7200 in the standard 3.6 Turbo which makes for an 300 rpm later boost onset but lover back pressure in the exhaust manifold and increases efficiency so that it makes more HP). Valve timing was advanced from standard for more overlap and richer mixture. Maximum boot pressure was .79 to .85 bar the same as the standard 3.6 turbo engine (although the onboard computerized boost gauge only reads to 0.7 bar as described in factory technical bulletin “9032-9307”.
The following information on the 911 3.6 liter – engine with increased output – K88 is from the factory technical bulletin “Xe”.
