928 s2
Hi, this is my first post on the 928 site. I currently have a 951 but have been offered a 1984 928 s2 automatic (with only 67000km or about 42000 miles) that I am interested in.
Does anyone have official specs or a road test of this car?
My biggest sticking point is that the car was delivered new in Japan as a left hand drive model - which is not uncommon as it is prestigious in Japan to have a left hand drive car as they drive on the right. It should therefore be Euro spec, right? Correct me if I am wrong, but the 928 s2 never made it to the US did it?
The problem is that if it is a true Euro spec S2, why does it have a catalytic converter and run on unleaded fuel? In 1984 Europe did not require cats, did they? If it has a cat I would think the performance would be severely reduced.
What do you think?
All replies are greatly appreciated.

Is it in the US? If so, then it's almost certanly part of the "grey market" cars from the early to mid 80s.
You were allowed to import one car per person, per peroid of time. Like one non US spec car in your lifetime, or something. Shops were set up to make the importation possibile. Many of them were fly by night opperation that did more paperwork than actual work. They certificed that their work was good, and there was no one cross checking them.
To be legal the cars had to be federalized. Meaning they had to meet US emissions specifications, marker lights, etc...
The catalitic converter, and unleaded fuel are almost certanly part of the federlization process. They usualy also had the smog pump installed. Also common was the replacement of the 8" european headlams with 7" DOT sealed beams. The disablement of the headlight leveling system. Additional frount and rear marker lights.
For imformation on the 928, refer to:
www.928s4vr.com
and
www.928gt.com
928s4vr.com has a breakdown of the modles types, and years. 928gt.com has various information under their specifications. Things like engine code, max hp, max torque, weight, top speed, final drive ratio, so on and so forth.

First and foremost, the HP is rated at 310Bhp for 84-86 S2.
Trq Rated at 295 Ft lbs.
LH injection
Dual Distributors
Dual Coils
ABS on the ltr MY
M28/22 and M28/21 Engine codes
16V
4.7L
For Federalization
Cats and smog pump installed
Side marker Lights installed
Hydraulic Lamp adjustment system removed
H4 Headlamp removed
Rear Bumper (rettes) installed.
There are exceptions to the rule, as some Gray market cars passed without all of the above items.
Hope this Helps!.

You need to make sure that it is an S2 model. "New" cars shipped by Porsche Japan had to meet the same basic smog requirements as US cars, so a "true Japanese-Porsche" of that vintage would have the same L-Jet engine as a US 84. An easy way to is the "dual 4-cylinder" distributor that the EURO S2 had. If there is a single 8 cylinder distributor, the engine isn't the higher-hp Euro model. No S2 would run on regular fuel, the compression is too high.
You didn't state if the car is in the US or Japan. If it is already in the US and licensed, it must have been federalized (that is why it has all the smog equipment). Even if it is licensed in one state it may be difficult to get it licensed in another state, especially if they have smog checks.
If it is still in Japan, it would be a nightmare to import that vintage of a car into the US. Even though the S4s and newer were "world cars" there are still many items for importing non-US models into the US. It can be very time consuming, expensive, and difficult to import a GTS, let alone an S2.

Thanks for your replies. The car is now in Australia, brought in buy a used car dealer. The price is good because Australian's hate left hand drive.
The car has the s2 designation on the back, but as I say with a cat and unleaded fuel, I am worried. I don't want it unless it is euro spec. As Rich9928p said, it is unlikely to be a genuine s2 engine running on unleaded due to the compressionr ratio.
Does anyone know what year Europe and Japan went to unleaded fuel and started using cats?
The genuine S2 never made it to the US did it?

I am very confused.
I checked the vin details in the engine bay and they start as wpo zzz. This is indicative of a euro s2 engine with 310hp.
Then I check the code/number on the engine and it is 28.20. My understanding is that euro 310 hp engine number is 28.22 (automatic gearbox).
Is it possible that Japan got a hybrid car or what? What do you think of all of this? Please help.

Ebs,
'mo details, betta' answer!!
Japan has available a 'Ton' of left hand drive Porsches: their stringent emissions legislation, as distinct from testing, makes these cars fairly accessible to the world market.
Japan has both German spec 'Euros' and unique Japenese spec 'Euros' running the streets of Tokoyo, all of which are 'ZZZ' cars. The latter ones are in many ways, identical to Canada/US spec cars.
So, before going further, are you questioning importing, looking at a car here, is 'here' in the US,......?? Any pictures, car history?

ebs-
First of all, if your car has catalytic converters then you HAVE to use unleaded fuel!
If you have a high-compression M28 engine, then you simply need to find unleaded with high octane. Not usually a problem.
Double check your engine code. If it is an M28-20, then that is a US-spec 4.7 liter; It should have one distributor and it has lower compression.
I was under the impression that all cars with the ZZZ vin code built from '84-86 had the 310 hp M28-21 and -22 engines. Some markets may have received the ZZZ body with the US engine, or perhaps your car's engine was replaced with a US spec motor. IN any case....with catalytic converters you HAVE to use unleaded!!
Normy!
