Aspire's Salvage Potential

[htc]

94 and 95 Aspire are OBD-I, 96 and 97 are OBD-II. Gas tanks for Aspire two-doors are the same as EFI Festy gas tanks BTW.

What about the fuel level sending units? Are they compatible?

How about your ash trays? Do you have super D-luxx ash trays? Huh?? :p

How are the seat belts better?

dang NP - duz I gots to say tnc every time? (tongue n cheek) I'll start using the razzi more, lol:p:p:p:p:p

These systems weigh you and look at the speed, impact direction and decide what to blow and how hard to blow it. That collapsible steering column now has sensors in them so that they won't be accepted for reuse if they collapse even a tiny bit. They are a bit heavier and more complex looking. Seats are heavier as well, all this stuff is, its no wonder these older cars get such good mileage, they are hundreds of lbs lighter because of safety stuff.

Seatbelts work in two ways:

1. To slow you down with the vehicle itself as it crumples in a crash, reducing deceleration forces to survivable levels. Without a belt, your body would continue forwards and hit the insides of the car. This is called the "second collision." When your head hits something solid, a "third collision" occurs: your brain hits the inside of your skull. The brain can also be "bounced" back and forth when it recoils from hitting something "bouncy," so interior padding is generally designed to absorb contact instead of repelling it. Think "egg crate" rather than "pool table bumpers." (I believe side curtain airbags are primarily designed to prevent your head from hitting the B pillar and any other objects which may come close, including the ground in a rollover.)

Impacts with vehicle interior parts (steering wheel, dash, knobs, other passengers, stuff being hauled inside the car) are lessened with seatbelt use. Other safety improvements, primarily in the late sixties, seventies, and so on include:

-collapsable steering columns which prevent impalement
-energy absorbing steering wheels which absorb impact instead of fracturing into sharp pieces (look at some of the old time wheels made of wood, hard plastic, etc.)
-padded dashboards
-soft, blunt shaped knobs and controls
-padded visors and breakaway interior pieces (which in the old days could serve as impalement type features)
-safety glass which shatters into many little pieces instead of big jagged ones
-laminated windshields

2. To prevent ejection from the vehicle. Ejection from the vehicle is strongly associated with being killed or seriously injured. Outside the car, you will fly more or less uncontrollably and hit whatever happens to be in your path. Poles, guardrails, other cars (possibly in motion), etc. Yes, once in a while people will survive just fine after being ejected, when they land "just right" and onto something that cushions their impact, but this is rare. When you read about this, it's not because it's common, but just the opposite, which is why it is noted in the news (the "man bites dog" effect).

Another possibility is partial ejection. You are thrown out a window or open door and the car either rolls over you that way or hits something that squishes you in the opening.

Types of manual seatbelts:

-Lap belts are the simplest type. Ideally, they hold you over your hip bones (pelvic area) and should not be worn too high up where they could squeeze your soft middle parts and cause internal damage. They should come up from the floor area at no less than a 45 degree angle in order to stay on your hip bone area and away from your gut's soft parts. I believe lap belts have been associated with internal injuries when the belt rides up into your gut and squishes your insides. It is important to wear these as tightly as you can tolerate for best protection. See next belt type...

-Three point belts add a strap across your chest (rib cage and collar bone). They limit the motion of your upper body and more evenly distribute deceleration forces across a larger area, as well as (ideally) preventing you from eating your steering wheel. It is important with these belts as well to pull them snug so the lap portion does not ride up into your gut. It is also important that you not tuck the shoulder belt under your arm, which will tend to twist your upper body to the side in a hard crash, as well as severely breaking only one side of your rib cage where the forces would be concentrated.

-Racing harnesses come in four point and five point types. When properly installed and used, they would provide the best protection from crash forces and being ejected from the vehicle. Five point harnesses add an "anti-submarine" belt between the legs to keep the lap belt in place low on your hips and thus keep you from sliding underneath the lap belt. This can happen when you are reclined too much or are not snugging the lap part tight enough.

Standard retracting belts come in two general types:

A. "Vehicle sensitive" belts lock up when the car moves abruptly, as in an accident or when you slam on the brakes. If you tug on these they won't lock up. To test them, you'll have to tap the brakes to see if they lock up.

B. "Passenger sensitive" belts measure the speed at which the belt is let out and locks up when it does so quickly. If you tug on this type, it will lock up.

Festiva and Aspire belts are passenger sensitive. The auto belts lap portion are also passenger sensitive. I'm not sure if the shoulder belts are or not. I don't recall getting them to lock up by tugging, but they may have been difficult to do that.

I like the passenger sensitive types since I can put on my belts, pull them snug, and then yank them to get them to lock up. In a crash, I am instantly held in place and there is no chance for the belts to unreel before lockup.

Seatbelts will stretch in a bad crash, so they shouldn't be reused after a crash. (The internal metal parts may also deform for all I know, too.) Stretching also helps reduce impact forces.

The most recent type of manual seatbelt has "pretensioners" which quickly pull the belts taught in a collision. This can be done by a small pyrotechnic charge which takes the reel the other way to snug up the belt. Like airbags, this is a passive system that you don't have to worry about.

My belief is that there still may be quite a bit left to improve on regular old seatbelts, from determining the proper sizing and angles to more modern stuff like pretensioning. One of the latest twists combines airbags with belts in what is called "inflatable seatbelts." The belt itself is a long air bladder which inflates upon impact, helping to absorb crash forces and increasing the bearing area of the belts on the body to reduce bruising, broken bones, etc.

^^x2, seat belts are seat belts..... Except auto belts, they suck, glad we don't have them

[neanderpaul]

How are the seat belts better?

[loknlode]

hay, I no how to spel froid.


well........our seatbelts are better.

[Movin]

The new DI Hyundai engines have pretty high compression,
Port fuel injection reduces the surface area that wet fuel
clings to so yes, cleaner burn with more of the fuel atomized
and less splattering around metal on its way to the chamber.
DI of course is better still.
All to meet tighter standards the government has decided
we need to have.

[geezerstiva]

Where does direct injection come into this? The carbed festys had higher compression. Did they change the,emissions standards after 90? Cuz that would make sense. was the fi a significant improvement in emissions,over the carb? I would assume so, otherwise why would they have changed :lol:

[zoom zoom]

So does anyone know what the difference in the injectors are between fi festy's and aspires? it's different part numbers, and I can't find any info on the other injectors.

[Movin]

Yeah I was reading my service manual the other day for a 88 and apparently the carbed ones had higher compression. It was 9.7:1. I think the commonly quoted stat is 9.4:1. Yet the carbed were rated 58 HP vs 63 on the FI. Wonder why they dropped the compression on the later ones?

To lower the oxides of nitrogen without adding more EGR.
direct injected engines can use higher compression because
they can drag out the injection to keep peak pressures low enough NOX
does not form.

Yup, strictly big brother and burning more fuel to make clean air

Sheesh, there is no braggin about going around an aspire stuck right in the lane in snow, and the festiva has a trailer loaded with snowmobile. Those poor little aspires are worthless!
Not even any good for snowboarding. Least they got 40mpg before they had to walk! Strip the aspire and put the parts in a festy, now you got something! Parts designed for a heavy slug in a light strong shell!

[neanderpaul]

I was driving one of the unusually quick carby festys. The kind that gets bad gas mileage and is unreasonably quick. I've seen 3 carbys that were that way. From a dead stop (where the festiva shines) it was even until I shifted. The extra 1200 or so rpms is where the teg pulled ahead by a car.
