Hi,

Was the 3.2 Carrera the same from 83-89, (apart from the G50 offcourse).

Just asking as I read that the 84-86 was different in the engine compartment.

Cheers

I think you mean the same from 84-89 ( '83 was still the 911SC 3.0, at least in the US).

I recall hearing about some minor differences in the engine compartment like plug wire routing etc.

HP up by 10 after '86 , I think ( reprogrammed DME).

Also, some changes in heater ducting etc.

Is that true about the BHP? did it go up by 10?, that means it is 242BHP.
I dont recall hearing that anywhere else.
hmm..

The HP on my 88 Carrera is 217 hp. It also has the G50 with hydraulic clutch system. The A/C and heater system is slightly different than the 84-86, but most parts are interchangeable.

84-86 have a different Clutch and FlyWheel.

Only the US models got more HP, first 207 bhp, then 217 bhp.
Non US models always had 231 hp

I think that non-US cars had 231 hp until the addition of the catalytic converter. Then the most recent 3.2l models lost power down to 217 hp. My dad had an '89 3.2l in France with the cat and it was rated at 217hp.

There is certainly some confusion regarding the 3.2 liter cars. According to published Porsche Factory literature:
1984/85 models = 150 kw
1986 models = 152 kw
1987 - 89 models = 160 kw
To calculate DIN horsepower divide kw by .736. Therefore:
1984/85 models = 204 DIN
1986 models = 207 DIN
1987 - 89 models = 217 DIN
To go a step further to SAE (USA standard) hp, divide DIN by 1.014. Therefore:
1984/85 models = 201 SAE
1986 models = 204 SAE
1987 - 89 models = 214 SAE

Not all reference material reflects the slight increase for '86 models, but after one has driven enough of them the '86 cars "feel" better than the '84/85 cars. Of course this is subjective, and all things must be equal (fuel mixture, gasoline quality, plugs/wires, valve adjustment, etc.) for a solid comparison. The difference might simply lie in the fact that '86s are oh-so-smooth. Also, when discussing "feel" one must remember that in the modern electronic cars, beginning in '84, within each model year (using a sample of 100 cars) you will find two dogs, 95 pretty equal cars, and three that really go. In other words, I've driven '96 993s that were absolute slugs, and '95 993s that were rockets, but on average that isn't the case. The same goes for '84/85 Carreras, on average they are not as good as the typical '86, but occasionally you will find one that is.

I've got a Euro '84 3.2 Carrera (and have owned serveral other 911's in the past including my current '82 SC). In the glove box is the factory German owners manual for model year 1984 as well as a USA owners manual for model year 1984.

Here's the differences (according to these factory Porsche owners manuals):

Compression Ratio - USA: 9.5:1
Compression Ratio - ROW: 10.3:1

HP - USA: 200 SAE HP
HP - ROW: 231 PS (equals 227.85 uncorrected HP) (correct me here if I'm wrong)

TQ - USA: 185 ft. lb.
TQ - ROW: 284 Nm (equals 209.44 ft. lbs.)

Weight US: 2756 lbs. (1250 kg.)
Weight ROW: 2662 lbs. (1210 kg.)

Tony: Your compression figures (Euro & USA) are correct, and they hold true throughout the 3.2 liter run (84-89). You are also correct regarding Euro hp, which is usually expressed as kw, in this case 170. 170 kw translates to 231 DIN hp, or 228 (rounded off) SAE hp. The goofy stat deals with the '84/85 USA models; I have factory literature that claims both 150 kw, OR 152 kw - for the same car! So, as I wrote above, they are either 201, or 204 SAE hp. Your book shows 200 SAE, which, I guess, makes the cars about 200 hp!
Your Euro torque spec of 284 Nm (Newtonmeter) also holds true through the entire Euro 3.2 run, but those numbers also get screwed up. The 284 number denotes "maximum" torque, but after the dust settles the USA figure of 185 lb/ft is for "Net" torque SAE, which is equivalent to 251 Nm and compares to 278 Nm (Euro). Got a headache yet?
Also, here's something interesting: ROW doesn't always mean "Rest of World." In '84-86 Japan received our 150/152 kw engines. In '87 Austria, Switzerland and Japan got our 160 kw engines (w/cat) and Australia got a special, puny, 152 kw engine with a modified control unit. I have not been able to trace distribution of '88/89 engines.
Cheers!

Pete,

On that note, how can you tell which market your car was made for? I know my '84 Cab is a ROW, but I don't know where exactly.

Peter Zimmermann

Every engine has an internal designation code stamped on the engine block (see page 31 of my book). Your '84 is easy: If your car was built for Japan it will be fitted with a 930/21, 150/152 kw engine. If it is an "ROW" car it will be fitted with the 930/20, 170 kw engine. If you don't have my book get a flashlight and look slightly inboard and forward of where the right cam oil line connects at the engine case. There is a horizontal surface on which the internal code is stamped. You might have to spray the area with a little aerosol cleaner (cold engine only!) or use a rag to wipe the area clean.
