Aluminum ECOtec intake manifold...pics:)
Wednesday, August 10, 2005 7:33 PM
ok i stumbled upon this and thought you guys might be intrested in this.
<img src="http://memimage.cardomain.net/member_images/3/web/531000-531999/531077_156_full.jpg">

Its an aluminum intake manifold that is a direct bolt on. The only modification is you have to drill and tap one hole for the throttle body. Due to the saab having a electronic t/b and not a wire controlled one. It Is a good setup for Turbo because it came off a turbo car but i dont know the effect on a n/a car. I dont have any numbers as the car isnt done yet.

It is smaller and very similar to the 2.4 manifold. its direct from t/b to the head. no loop or anything. liek the plastic one.

the good part....its about 250 bucks.....55352121
bad part........you can only get it through a saab dealership...part number does not work at a chevy dealer.....and its a 3-4 week wait to get one because no one in the us has it in stock. It has to come from sweden.And i WOrk at a chevy dealership and have a friend who works at a saab dealership so the info is right.

So i just thought i would let you guys know what it is.
if anyone is intrested in the this one it is for sale. Email me 250 shipped.

On a side note im in the middle of doing an engine swap to an eco...so the engine bay is a lil dirty

Good find ! thanks man.

this would be better for direct port but being metal it will weigh more as well as more heat soak

im going to the dealership tomorrow i think hell if someone wants to send me one ill do a nice dyno test for you guys...i do have free dyno access

saab 9-3


i dont remember is the motr he got was the low boost or high boost , i believe it is the high boost motor

It came out of a saab 9-3 2.0T.....2005 model year.
If you want mine its for sale....250 shipped e-mail me

It does not give any performance advantage on a NA, the alloy does soak up the engine heat and you get hot air drawn in, rather than nice cool air.

Porting the standard inlet manifold gives a better (and cheaper) performance gain.

I fitted the 68mm 2.0sc TB to my 2.2 ecotec with firstly an alloy inlet manifold then the modified standard inlet manifold.

The power decreased with the 68mm TB + alloy inlet manifold (it got so hot you could not touch the inlet manifold) and the performance increased with the 68mm TB mounted on the modded standard inlet manifold.

The 68mm TB calms down the lumpy cam idle.

IN the Gm testing the stock plastic intake mani was good to 400hp thats far more than any of us were putting down the only real benefit of this would be for direct port otherwise its a waste

I want to know how the TB calmed down the idle? At idle there should be no difference with a bigger TB, unless the stock one was bad, or something messed up.

Is there any way to prevent the heat buildup and benefit from it? I know header wrap is meant to hold heat in, but theoretically shouldn't it also keep heat out?

Not really sure, but it's possible the standard 58mm was bad.

Maybe it's the bigger inlet pipe, it had 60mm pipe, now it has 70mm.

The engine is much smoother with the bigger TB and pulls to the rev limiter quicker.

It certainly works well with the other mods I've done, just need to get a remap of the ecu and a final rolling road figure.

I'm expecting @190bhp at the flywheel.

heres what i came up with from the saab dealership closest to me (about 200 miles away)

Roy, the intake manifold, part number 55-352-121, is $153.00, is a
special order part, of which there is 1 available in the country.
Please let me know if I can be of further assistance.
Thank you for the inquiry,
Steve Lee
Saab Parts Manager
but i suppose if its of no benefit on our motors then oh well haha would be a nice custom show piece though

wrong. the heat that the intake manifold would soak up is coming from where the flange meets the head. So wrapping the outside of the manifold wouldn't do anything except help to hold this heat in. What could work is a phenolic spacer between the intake mani and head. Plus this intake could be iced at the track, to bring it to sub-ambient temps. I do this on my car and it definitely makes a solid difference in trap speeds. On an N/A car i doubt the saab manifold would be ideal unless you want to avoid fuel puddling with nitrous and blowing up the intake. The longer runners of the stock mani help to promote low-to midrange torque qhich is the strong point of the eco.

Ceramic thermal barrier coatings are very effective for this job, and they don't need to be applied by a specialty coating shop. Techline Coatings

OK.....

If you have the engine at high RPM, the air is going to be moving so fast that it will not soak up much heat from the intake even if it is metal. There is little time for the transfer of heat.

Who took thermodynamics in here?

A plastic manifold doesn't hold up as well to boost. Even if it has a blow out plug, it could still happen.

well see, by that same theory then, air traveling through an intercooler would be moving too fast to be cooled.... But we all know intercoolers work... Granted an intercooler has more contact area for the air to touch but the intake manifold still runs on the same principle, just less contact area so the effect isn't as great. Sounds like someone needed to pay more attention in thermodynamics

Give me a break. Your wrong all the way on this post.
The plastice manifols hold well to boost. there are many ecotecs running over 10psi on them. I know of at least 2 that have had 15+ psi on them, with no problems.

The heat from the intake manifold itself will be drawn into the combustion chamber, which in-turn will heat all the air traveling with it.
Getting the manifold ceramic powder coated inside and out, and adding a heat dissipating spacer/gasket would be the only way to gain even the smallest amount of performance in the application(that's only my opinion).

you guys are so full of it.

I mean....how many engines has gm come out with that have metal intake manifolds?
just cause its attached to the head doenst mean its gonna get hotter. Look at the
Ho intake manifold....or the intake manifolds on the 3.1 all the way to the 3.8. I know some 3.8 have plastic but some do have metal.

I should have just kept my mouth shut on this intake mani and let all you pazies crying out for a new intake manifold just keep crying about it.

It came off a production car.....didnt have problems as it is still being used on the car. it came off an 05. But to sit here and bash it is crap.
