Gonna have to say this was an awesome mod. i have been driving all night and holy ****, car feels so much faster now, great mod and i highly recommend it. yeh maybe 0-20 mph has slowed a bit but man get ready to be tossed in ur seat till upwards of 70+.

 

Have you tried driving in I or low yet? It makes a HUGE difference in the performance of the auto. I also have the RSM lightweight pulley, so it helps the car rev a little faster. I have the alternator pulley I bought off of a member on here, but I still haven't put it on yet.

 

yeh im always in i when goin zoom zoom. RSM pullet whats that and where do i get it, hehe

 

This is a thread on it from the site...

I paid $150 when I bought mine, and now I see it is only $40.

RSM was bought out by z-spec, so they are probably limited to their stock on hand.

It is the same size as stock, only lightened.

I've had mine in since June of '06 with no problems so far.

I've heard good and bad on these, like it can cause vibrations and premature engine wear, but we also have twin balance shafts to reduce vibrations.

I guess just use it at your own risk....

 

my header is on the way here and i will be buyin a dp soon after. i would love to get this thing in to the mid 15s before i go any further. even tho i live in southeast texas the winter is starting to go away so i will not have the cold weather i would like to have. so i may have to wait till the fall before i get the times i want....

as far as the manifold swap goes it is by FAR the best mod i have done to my car performance wise. i really recomend it to anyone who is thinkin bout it.

as far as times before i was running with the manifold i was puttin up some constant 16.5s trapping around 83-84mph. after the swap i went back and my times dropped to 16.4 at 86-87mph. so there is a def improvement if you run the quarter mile with this mod

and remember..... i have an 07. i have heard of the 05-06s not gettin the gains that the 07-08s are. think about that when deciding on the swap.

 

is the intake manifold the same as as 98 2.4l malibu

 

no, sorry it is nothing like that at all. This is only used on the Ecotec engines.

 

o ok....does anyone have a part #

 

I don't have the part number but here is a link to the kit.

that looks like what i have already what im tryin to do is upgrade to the 2.4l manifold. which i believe is made out of aluminum or some kind of metal not plastic

 

I am not sure, you do have a 2.2 right? This is a 2.4 manifold and its made out of plastic.

 

yes i do have a 2.2. mayb i got informed wrongly about the 2.4 manifold....but ill do some more research and see if this is what im lookin for

 

Both the 2.2 and the 2.4 manifolds are made from plastic. The 2.4 has a larger plenum and larger runners which pushes the powerband higher. If you are looking for an aluminum intake manifold, be prepared to pay alot. Low to mid boost applications are just fine with the plastic manifolds.

 

good to know thank you....
