Performance.......

Why would a stock 91 Festy with 250K have more noticeably more pickup then a stock 92 with 165K that seemed to be running fine generally?

[Safety Guy]

Too many variables to know this. Here are a few:

New from factory, even parts made and put together on an assembly line may produce slightly different power outputs. I have no idea what the range is, but I wouldn't be surprised to find a 4 to 5 hp variation.

How was each car serviced through the years, by how many different owners with different ideas of "service?"

What kind of parts, lubes, fuel, etc. were used all those years by each car?

What size tires are on each? What state of engine tune? How clean are the air filters?

And so on...

When I taught driver's ed, we had mostly K cars, Horizons and Sundances. All were 2.2s. Even between the same models, some seemed quite "peppy" while others weren't.

Maybe the '91 has a stronger clutch and the '92 is slipping ever so slightly that it isn't hardly noticable.

[mattman]

my 91 felt stronger than the 93 i have now or any of my parents 5 they have owned an all of theirs were bought new

[chrisofna]

Maybe one was beat on by the previous owner more than the other?

[Grey Vw]

Maybe it was a full moon that night, was exactly 53 degrees outside and the workers all had green shirts on when the car was being assembled.

[Festiva Time]

Ignition timing makes a big difference. I have read that Festy with Autos are slower. Emission control changes? Air filter clean? Tires inflated properly? Elephant in the back slowing you down?

Forgot to mention that the quick one is blue and the slower one is red.

Well, thats not right. Everyone knows red ones are faster! :p

[mattman]

mine was flash yellow an it seemed much faster than any other festivas in my town back then an beleive me if another festy found itself by another at a redlight on the weekend it was on mine always seemed to have a lil more than the others

the new skyline GTR's vary by around 100hp at the wheels...i believe the article was in car and driver...

[getnpsi]

Remember 5hp is a 10% gain with these cars LOL... I just thought about it a second time typing it.

that's a little bit different
all the new gtr engines are hand made
not made by the same machine/computer
more room for variances

[perucho]

You mean hand assembled? They all use the same parts. Parts made by a machine/computer.

[blkfordsedan]

Personally, if I dropped that kind of cash on a GTR to find out the next guy could have 100HP more, I would be pretty upset. I would think qualified engine builders using production parts could get more consistent. Isn't there some type of quality control? Maybe a final dyno test? Especially for a car as dedicated and expensive as the GTR. Wouldn't Nissan just fire the guy that builds the weak ones?
