Why is a plastic manifold bad? It's lighter, cheaper, easier to produce with very smooth inner surfaces (won't disturb flow as much as a cast aluminum surface), and will stay cooler, thereby transferring less heat to the intake charge. All that sounds good to me.

There are numerous engines on the market of more advanced design making significantly more power that do just fine with a plastic/composite intake.

You can weld plastic, its called plastic welding hahaha.

Looks like GM is messing with Subaru. Since GMs were the first cars to carry plastic intake manifolds

Also I wonder if switching to this plastic one on my 2000 RS would it change any of the performance?

Pat's right,

Plastic in the terms Pat pointed out is better then aluminum. I think the big issue they had to overcome was heat, developing one that could withstand the heat. The new 2.0t in the new turbo legacy has a plastic intake. So apparently they have figured out how to handle the heat.

Default Swap?

Has anyone swapped from the aluminum manifold to the new composite one? Will everything bolt up? Also has anyone looked into the price of acquiring one of these?

I've never had a chance to see one in person. Anyone know if the dimentions are the same, like the lenght of the runners, or has there been any significant change in desgin (other than material)?


Cheers,
Chad

well take a look at the 04 wrx's and sti's, its been mentioned that they have the plastic intake manifold as well, also seems to clear up the need for the grounding mod, my idle is pretty smooth, only has the occasional just from 5-600 to 900 rpm

Ever here of the SAAB 9-2 yet. Thats not a rumor.its true.
GM has alot of shares of Fuji Heavy Industries with the truck devision. Dont be surprized if there is a WRX engine in a Cavilier pretty soon with AWD

When that happens im buying an s2000
even though honda is on my $hit list.
Autoweek: "S2000 owners be prepared for your s2000 to be more civilized." In 2004 honda will be releasing the S2200. Coupe and convert. It will have more displacement (2.2L) but will have softer suspension, lower revs, heavier, bigger, and have the same HP.

1st gen s2000's used will hold their value very well. Or I could buy the EVO RS thats is coming next year

I was discussing this with Keith at TWE and he actually thought it might be a good thing as well. They are going to flow test it once the SCCA Nationals are over and see how it compares to the older one. If it flows better than the older cast ones, then you won't need to extrude hone your manifold for high output NA builds like the one I will be doing in the spring. Yes, it will mate up...TWE has already done that part on Irish Mike's car.

Ummm, 18% is not a whole lot of shares...not even enough for controlling interests. Subaru and GM have already axe'd plans to jointly develop a 7 passenger vehicle as GM didn't want to listen to Subaru's ideas so Subaru said fine we'll do it ourselves!

Plus 2004 is the last year for the Cavalier, in 2005 Chevrolet is releasing a new "small" car called the Colbalt that will still be FWD, but will have an SS version with a supercharged motor rated at over 200 HP!





Quote:
DETROIT - Chevrolet Motor Division will name its all-new small car Cobalt, Mary Larson, marketing director for Cavalier and Cobalt, announced today.
"We think Cobalt - a word associated with power, strength and dependability - is a great fit for our new small car," said Larson. "Cobalt will feature a clean, contemporary design, a spacious interior and excellent dynamic performance. Our dealers and customers will be thrilled with Chevrolet's newest small car." Cobalt will be part of a new small car lineup at Chevrolet. Cobalt will compete in the premium small car market against imports like the Toyota Corolla and Honda Civic. The recently announced Chevrolet Aveo will compete in the entry-level small car market.
"A large part of the small car segment is made up of consumers who want the size and efficiency of a small car, but also want a car with desirable features, better performance and a more upscale package," Larson explained. "Cobalt will deliver all of this."
The Cobalt will be introduced as a 2005 model. Cobalt will be built at GM's Lordstown, Ohio, assembly center.


There will be several models including: base, LS. LT, and SS. The SS will produce about 220 hp.
"The supercharged SS will be a low volume, kind of halo car for the cobalt brand...It is really aimed at the import tuner crowd"

I have faith in the new manifold. Subaru is an engineers company, not an accountants. I really beleive that they would not put that manifold on inless it was as good or better. Its definatly easier and cheaper to make. I do think that saab 9-2 (WRX) is going to be a horrible thing, for both saab and subaru. it cheapens saab, and totally steals subarus WRX so rich people can buy them and be surrounded by leather. CHevy will NOT make a cavalier off a subaru. cav is the entry level car, theyde have to charge more for the AWD and then mark that up 300% to rape people on profits.

That new chevy-- Is the 220HP version the supercharged ecotec?? that would be a pretty good powerplant. solid little motor (saturn ion redline, derived from saab 2.0t ecotec).

I wish I was working...Ide be happy being bored at a normal job right now..being laid off turns you into a whole other person. I look at the world very differently over the last couple of months (maybe the last couple of days even more).
