Sry guys imma kinda newbish with cars.I hear ppl talking about replacing cats and stuff in their cars.Can u help me out??Thx.

EDIT:Also is it possible to put a 90 T2 Hood on a NA 90 Stock hood?

 

Cat=Catalytic Converter. It is located behind your exhaust manifold, and before your mufflers. Emissions Standards requires them to be on all vehicles which are to be used on the highway. It basically filters out bad exhaust gases and makes the exhaust more clean. It also robs horsepower because it is restrictive.

 

Ok thx.Is it possible to put a T2 hood on a NA?

 

Cats can also fail. When they do, they generally clog the exhaust, and increase backpressure significantly. This is usually followed by a blown engine.

yes but offer no performance gains...it does look sweet tho

 

Yes on the TII Hood on NA question.

 

Of course it is. The real question is why would you want to? Unless you are running a turbo engine swap with the TMIC, it is pointless to have a turbo hood with a naturally aspirated engine.

 

Yea It usless unless I have turbo.It looks kewl tho I dont wanna rice it out tho.

 

I suppose if you had the T2 hood, its always more incentive to eventually do a turbo swap. Which usually isn't a bad thing =P

 

Putting a T2 hood on an NA is generally something thats frowned upon within the community here. It kind of falls under the category of makinf people think you have more poines than you really do under there. It is a direct swap though, yes.

 

it a furry little animal that meows and catches stuff!! hehe, j/k bro!! u dont need a CAT take it out and replace it with a RB straight pipe!!

 

The TII hood is aluminum though, so it does take some weight off the car. Come on people...

 

the GXL came stock with the aluminum hood, hehe!!

 

it did!?
is there anyway to check, i heard something about the latch.
i have a 90 gxl and i was wondering, it was a bit heavy....but i did previously own a CF hood

 

What Aluminum hood stock! mines like 500 pounds!

 

not all gxls came stock with an aluminum hood. some cars had em, some didn't.

Cats (catalytic converters/catalysts) are a 2 part system (there's 2- and 3-way, and a couple of other types, but i'll explain the type i know which i believe is the 3-way type).
the inlet pipe from the smog pump feeds into the center section of the catalytic. the cat has two pieces inside of it with a space inbetween them (the center). the first section is the "oxidizing reduction." it takes the exhaust fumes and removes all the oxygen particles, leaving HC, C, and N. the second part ("oxiding") uses the smog pump to feed itself oxygen, which then takes the passing HC, C, and N to turn it into H20, CO2, and NOx (ideally), but combustion and exhaust is not ideal, so we also have CO and NOx.

if anyone wants to correct any terms or such, be my guest.

 

Picture of skeletor in 5...4...3..2...

 

NOT all tII hoods are aluninum, i have a TII hood thats steel, it sucks.

 

wow, this thread is a whole lot of nothing...

 

coldfire - what would make it "something"?? what would _you_ like to see? what contribution would make you say "i'm glad i read this thread" ??
please, leave suggestions and comments. we are here to satisfy _you_.

 

I'll trade you hoods....I want a N/A hood when I put my FMIC on to keep my car on the down low.

 

I am wondering, which GXL's did come with an aluminum hood? My '90's hood weigh's like a dead horse

 

..it isn't hard to tell the difference between steel and aluminum - knock on the hood then, if it sounds denser, more of a "thunk" it's probably steel. aluminum will be more of a "tink". hope this helped.

 

...Or stick a magnet to it...

 

Typically the only GXL models with an alumiumn hood were the S4 models with factory air conditioning and/or auto tranny and/or rear seats.

It was not standard by any means.

And this thread is done... every question has been answered here or if people would search.
