European vs US Carrera

[mhicks85]

Anyone know what the difference is between the Euro spec and US spec 84-89 Carrera's?

[WPOZZZ]

RoW had more hp, higher compression and usually a lsd with tranny cooler.

[Porsche84]

I have an 84 euro. The 4th and 5th gears are taller so you could get a bit better milage on highways. I think the headliner is white on euros and black on the US cars. The euro has side marker lights on the front fenders and a rear fog light. Mine had a tranny cooler but no LSD.

[Porsche84]

I just noticed WPOZZZ's user name which reminded me that the Euro will have four Z's in the vin. Make sure the DEP papers are in order so you can get the car registered.

I cannot say about 1985 - 89 . But on a 1984....

Probably more things , but besides the obvious instruments & other body DOT items. I know of four straight away :

Lower number final drive gearing

Front radiator type oil cooler

Trans oil cooler

231 hp vs. ?



Probably this also : lower ride height & maybe different valving on shocks / struts)

[RatBox]

I should have said lower 5th gear (which is what I meant) . I did not realise 4th was different also.

[hcariss]

I might be wrong but I think the Euro Carreras came with 15"x7/8 wheels

There really is not such thing as Euro spec car its ROW/US spec, however Euro spec does apply to engines.
ROW/US - Chassis plate in different location and no window tag on Euro cars. Front and rear fog lights, front wing side repeaters, Headlight height adjustable and H4 only, US rear bumper rubber is larger, lower ride height.

Number of cylinders - 6
Bore - 3.74 in / 95 mm
Stroke 2.93 in / 74.4 mm
Capacity - 193 cu in / 3164 cc
Compression 10.3 to 1
Horsepower - 231 hp (No Cat)
Fuel - 98 RON

I believe the ROW cars are also broken down in Japanese (around here there are a few examples) and Aussie markets, where I believe they were sold with lower HP to conform to emissions regs. So to further focus the description, the term Euro is used. My 85 "Euro" did come with 15" wheels but I can't say if that was the norm. Cheers

Correct, some countries have a different ROW spec. Check the first code you will see on the white label is C?and this is to identify for which market the car was produced. COO=Germany, CO5=France, C16=UK, C23 Belgium, C32=Saudi Arabia e.t.c.

like I said engines are different but they're classified as ROW cars, unlike US vehicle spec which are unique to the USA(lights etc as detailed). My understand is the lower compression US spec engine is due to the lower RON available there.

The spec table I posted is a 84-89 Euro spec engine, these are the others Euro spec's

Early with cat: 207 hp (engine type 930/21)
later with cat: 217 hp (engine type 930/25)
84-89 without cat: 231 hp (engine type 930/20)

I own a 1987 Swiss market Carrera. There are a number of things that are different than its US counterpart.

The RoW tranny gearing is actually a bit taller for fifth gear G50s. There is a pelican thread about this here: g50 transmission gearing question. Mine does not have a standard transmission cooler.

The lighting has some differences. It came with H4s as standard, though mine are not height adjustable except in the usual way of screw type alignment. Rear turn signals are amber and the front indicators only light up with signals and not as running lights. As well, there is only a single lens at each front corner and not two. There are fender side mounted repeaters for signals. There are rear fog lamps; the G50 cars have two in the reflector and earlier cars have one hanging on the driver's side from the bumper.

The data and vin number plates are mounted in a different location than US cars. there are no vin plates mounted to the A-pillar.

The rear bumper has smaller over riders. My car came with 15 inch wheels, but I believe that Fuchs were still an option at this time, whether 15 or 16 inch.

The gauges have measurement indicators in metric. My headliner is not white but interior colour: blue. Interiors are also often upholstered in cloth. I believe almost all US cars were leather.

And, of course a bit more power. This is due to higher compression and perhaps a couple other things.

As some mentioned it, the JDM (Japanese market) cars' engines are the same as the US market (I believe). One other rather unique thing is that the carpeted hump between the rear seats is actually upholstered. I don't have a picture, but it is kinda cool.

Here is another thread that deals with the US/RoW differences: Euro vs USA differences pics

The specs are often, but not always, the same for Canada and the USA. In many respects you have RoW and NA (North American) differences. Sometimes you get RoW, Canada, California, Japan and USA (except California). Simply saying RoW and USA is quite misleading if only because specs for Canada are almost never RoW.

ROW or US, they usually came without an LSD. Up until the recent GT3, almost all 911 variants have come with open diffs. regardless of market. It's always been an option, but it's not a common option on cars of this era, not even on 930s.

I know I'm guilty of lumping the Canadian cars in with the US versions. Generally, the differences are pretty minor and typically limited to some stickers, metric on the gauges and... Well, that's all I can think of at the moment. They didn't even have daytime running lights until '89.

The ride height ceased being different around 1983.

I guess I was lucky. My 85 Row had the lsd. My 79 930 did not and it was quite puzzling.

Some of the euro 3.2's did not have an O2 / Lambda function. Some had a premuffler in place of the cat.

Biggest difference is the compression and the tranny cooler.

I would not get to excited about the compression difference.

Once both are chipped there should be less than a 5hp difference.

As a matter of interest what would a US spec produce chipped, ie with cat and lower compression?

[911st]

My us 85 on the dyno I used I pulled 217whp with a SW chip and cat bypass. That could be as much as 255chp but that seems optimistic.

As many of the euro 3.2's did not have a cat that might be a better comparison.

It is possible that on US gas a euro motor might even make less peak HP as the US motor would be able run more timing advance safely.

See the dyno section in 911chips.com for better info.

To confuse this even further.....even "Euro" is not one spec to compare US and Japanese market cars to. The Europeans had a choice to go purely "Euro spec" as is commonly used in discussions here....OR....they could "opt into" a catalyst car much like US spec and have a tax advantage. This was option code M298 for "Euro" cars. Such cars, like US spec..would typically not have looped/finned trans cooler....whereas the non-cat Euro cars typically did have the trans cooler.

Interesting too for those that followed Bruce Anderson's writings. He claims that almost all 3.2 engine types, regardless of Euro/USA/cat/non cat....all pretty much showed 220 hp on the dyno ( +/-)...so the VERY wide hp range catalogued between 200 and 231 hp was not all that great.
