Great info, this may come in handy.

 

NIIICE....dam air injection/egr crap!!!..the block off header looks good

 

our webadmin is working out teh bug, we did not know it was there, last we knew you could post and see public forums without registering.

 

Pardon my lack of knowledge, but whats this 'air injection' buisness all about?

 

Pardon my lack of knowledge, but whats this 'air injection' buisness all about?

Its a new emissions system that was introduced at the end of 03. It has an electrical air pump that blows fresh air through the manifold into the head right into the path of the exhaust stream. It operates during cold starts when the air fuel ratio is very rich in order to help light off the catalytic converter faster and to prevent hydrocarbon loading of the cat. Its purely an emissions system - no performance benefit at all.

 

how does the air injection hook up inside of the header itself? do you have any pics showing where the inlet to the header tube is? what considerations do you have to take when porting a header with air injection?

Cool, I figured it would have to be emissions related. Thanks Boosted! :thumbup:

 

good info, should make this a sticky

Jeez barber calm down bro - I will answer your questions - Its my 10th Anniversary today so I've had other things to do

Anyways porting is pretty much the same, I just have to be careful to plug off the air injection holed while i'm porting so I don't get a bunch of metal debris in there.

As for teh rest of it, iIf you need to know faster than I am telling you just subscribe to http://techinfo.toyota.com for a day and check out the engine section of the 2004 Celica New Car Features book

Boosted2.0, properly something you already know but here it is...

[URL='02 Celica gts fits on '03 Matrix Xrs.]http://matrixowners.com/forums/Ported-02-G-T-S-Header-Into-My-03-X-R-S-t52376.html[/URL]

Just so you know all '03 Matrix Xrs' do not have the air injection system, only '04 Xrs' and up .

 

Yeah I saw that the other day when I verified the exhaust manifold parts numbers - the Matrix got the air injection after the Celica did by a couple months.

 

awesome. this totally clears things up for me

 

does the blocked off header work on the old style head 2000gts?

I would imagine so - but I have not verified it personally.

 

I cant see the pics are there any new threads that have them up?

 

What do you need to know? Just check the build date on your celica.

 

its an 04 gts engine but everything is from a 00 so I dont need the air injection I just wanted to get a visual so I can brain storm what I might need to do before I get to work. the engine is already in and I cant get it certified untill I fix the header... it sticks out like a sore thumb and teh smog guys wont touch it. I was wondering if I could cut the tube close to the header and pinch it off or something so its out of sight...
