Ok so CrateEngine Depot.com has an intake manifold for the ecotec engine. it is a fabricated alluminum intake and it accepts a 75mm LS1 Throttle Body. Heres my question. Does anyone have this part installed. and if so how do you like it? I know they also sell the 2.4 intake but i prefer a metal intake over a plastic intake manifold.

 

Unless you are planning on runnin n02 the plastic one will be more than just fine, by dammit it may be better.

I am pretty sure the plastic is lighter than the metal one...just food for thought

 

even with nitrous you dont need metal. Maybe metal at 20psi + of boost

 

to use the larger tb, you have to tune for it. Otherwise get ready to drive around in limp mode...

or boost. Basically if you're going to stay na you could stay with plastic. Maybe move to the 2.4 intake. If you're going to run nitrous or boost above 7-8psi it would be wise to go to a metal manifold.

 

A plastic intake manifold is better then a metal one with n2o, if the nitrous pre-ignites the intake manifold will absorb alot of the force, if it's metal, you'll likely crack your head.

 

Edit: Sorry I just read the answer to my own question

 

Plus, there would be no point in installing an LS1 TB. That would slow the air velocity too much. Plus, you can't tune for the larger TB.

 

the plastic mani is not always the best bet when it comes to N2O. I have seen Cobalts have it back fire on them while they were racing and blow the manifold apart

 

2.4 mani should be able to stand a 75 shot easy, since they are a 1 piece design

 

no heat soak on a plastic manifold aswell. cooler intake temps

 

True, but I'd rather blow a cheap plastic manifold then break something else that's worthmuch more money.

 

i would think the 75mm tb would be WAY too big for the balts, though i could be wrong

 

Not if you're running 500 whp like that manifold is designed for...

 

picture of it installed on a dragster, there was a badass pic in modified mag of the whitfield racing cobalt in a mobil 1 ad and its installed there as well

 

thats why i bought one before i go and spray my 2.2

 

Will this mod be possible on a 09 2.2l? Or do they only fit the earlier trims?

 

CED makes a 2.4 Intake Manifold kit, you will want that kit instead of this

 

link?

 

Can't use an LS1 TB on a cobalt unless you have a standalone.

A hahn or vulcan piece would work assuming the PCV ports line up.

 

i agree link please

 

yea im turboing mine and im still gonna run a plastic 2.4 manifold.

we want the link to the after market aluminum intake manifold...

thanks for the link... do you know if there are any 2.2 TB spacer and where i can find one?
