does anyone know ALL the differences between the euro spec Jalpas and the U.S. versions? what does the euro spec have/not have and does anyone have a euro spec Jalpa in the U.S. (what issues did you have, if any, when you were registering it in your state?). thanks for any replies....

It's all in the parts catalogue...

When Frank Sinatra got his Miura S in 1970, he said: “If you wanna be someone, buy Ferrari - If you are someone, you own a Lamborghini”.

I think alot of people would like to know the difference...me included.

There are only two main differences.

The biggest one being the US has sealed air boxes. These were required in the US to reduce fumes and contain fire. In the earlier models these made changing the plugs very difficult and usually required dropping the engine. On the later models there added an access panel that allowed easy access to the plugs.

The other main difference was the exhaust. The US has higher emissions standards and required the exhaust to have converters and different mufflers.

These are the only main differences in the cars.

Did all 86-88 models have the access door for the plugs?
Does the euro model sound and perform better?
It seems most 83 Jalpas even in the USA have different more rounded airboxes with the one bolt on top of each carb...or does that mean it's just a Euro model?

Yes all 86 and up had the access panel. Anytime there is not a converter the exhaust does sound a little better, IMO. And performance would slightly increase with less back pressure.

The air box that you described is the euro version. The image below is the US airbox.

david, is the u.s. version engine you posted rebuilt? hoses, wiring looks a bit thicker than normal?

...also, what about the '85? they seem to have the carb box covers but the screws are screwed onto the sides and not on top of the boxes - at least on the euro specs. did these versions also have the access panel? thanks...

Yes it is rebuilt. That is my engine. I have twin turbos so everything needed to be upgraded. but the boxes are the same.
