Who's got a "Euro" Engine?

[bento]

I'm hoping the Euro-spec engine people might chime in here.

Is there any problem with sourcing a Euro 3.2 liter engine and installing it in an 88 Carrera in Kalifornia aside from the smog logistics?

Seems like a good way to pick up an extra 20-30 horses (w/Steve W remap of course) without having to go the 3.4 route or the full monty 3.6 swap. Am I missing something?

thanks

I do. But then again, I am from Sweden.

I have an '84 Euro in the Bay Area and it passed smog with flying colors earlier this year. Sounds feasible if your '88 motor needs replacing.

Availability of decent gasoline.

10.3:1 compression, lack of a knock sensor and the 91 octane piss California consideres "premium" gasoline is not a good combination.

87 3.2 euro without cat. Porsche advise is to use 98 gas but i,m not sure we have the same system of rating here in europe.

[911teo]

There is a difference in rating... In most countries the headline number used is the RON (Research Octane Number)... In the US the headline number is the average of the RON and the MON (Motor Octane Number... which is on average 10 points lower for modern fuel) with the (R+M)/2.

So a RON 98 fuel in Europe is possibly equivalent to a 93 US rated fuel.

Or, if you can't find one, get Euro 3.2 P/C's and have it done to your engine.

89 911 - Thats the thing, trying to avoid rebuild costs by buying a used engine and then selling my high mileage one. If i were to rebuild, it would likely be the 3.4 route like you chose.

91 CA gasoline sucks, period.

What about the aforementioned 91 octane gas? Any problems?

Other than a valve adjust or two and oil changes I don't know much about my ROW 3.2, but it has a Steve W chip and runs great on 91 octane and passed smog easily with a cat and O2 sensor.

My euro 3.6 runs great on 91 California gas.

My 911 runs great on 91 gas.

Umm, your motor also has knock sensors to retard the timing when detonation is detected. Us peasants with earlier motors don't have the same luxury and thus have to be more careful, especially those running aftermarket computer chips.

My 3.5L twin-plug runs good on 91 but would certainly run better using 93.

If it's any consolation, the Euro 3.2L is in all likelihood closer to 10:1 than 10.3:1, just like static compression on a 993 3.6L is somewhere around 10.7:1/10.8:1 rather than slightly over 11:1 as advertised.

You may have to blend in some 100 octane with the 91 (1:3 or 1:4 parts) if considering a Euro 3.2L motor, especially on hot summer days in California.

The higher compression Euro 3.2L motor will pass smog as easily as a regular 3.2L as long as the emissions components are in place and function properly.

I agree, if tearing down the top end you may as well make it a 3.4L (w/ 9.8:1 CR) if you have to purchase P's and C's anyway.

There were a number of different Euro 3.2's. Some with cats, some without. I know the non of the British motors had cats and all required leaded fuel (98RON). Australian cars ran without cats until '86 and then they came inline with what you guys had from '87.

The 231 hp cars all need 98RON unleaded or leaded fuel.

Man, I'm glad I never bought that Euro 3.2 from about a month ago. What would I run it with?

But just to add something to the thread, I think Steve would retard the timing in some manner as he installed the chip. Wouldn't that enable the Euro 3.2 to run 91 octane?

Yes, the timing maps would probably have to be backed down a bit to safely run 91, and yes it would decrease power a bit as well but the reduction in throttle response would probably be the most noticeable for many drivers.

Andial for one won't build a street motor on 91 octane with more than 10:1 CR MEASURED, even with twin-plugs. Better to err on the conservative side with a street motor IMO.

The timing increases that are generally possible when running higher quality gas is what you generally "feel" seat of the pants and you would simply have to run less advance with a lower grade of gas, as a general rule of thumb.

Still beats a sharp stick in the eye.

I really hope that is true.
