2.3L intake on 2.4L 98 Z24
Wednesday, September 23, 2009 6:16 PM



Ok people...so I saw and read in a couple of threds about installing a 2.3L Quad 4 intake manifold onto a 2.4L Twin Cam engine...SO I went to pick a part, (scrap yard here in calgary) removed the intake and throttle body off of a Quad 4 and I have hence been working on the manifold to match it up to the cylinder head that is on my engine in my cavalier. Almost done. Just have to paint and rig up the EGR. I just wanted to know the opinions of people whom have done this install, thinking about doing it, or are staying away from the install...In a couple of weeks I will be finishing the exhaust on the car so that will not be an issue anymore.

Let it begin!

I think AJ has an intake manifold from a Grand AM on his Twincam, but I am not sure if it came from a 2.3 HO or not.

ok time for me to chime in, HO= garbage, LO =good especially if staying N/A, HO lose HP, LO gain HP, so if you want to stay with HO, go ahead but you will be VERY disappointed, and yes running LO, but Im also one of the fastest on this site so be smart LO mani, but I also dont see list of mods, so if this is your first one, junk the Ho go LO, and get the matching tb, which will be 56mm, but be carefule, there were different throttlebodies, and different throttle backets depending on year and application, any questions feel free to ask

okay sorry i know im not from this region but it caught my sight... i never did understand most of the engine related threads unless it was explained "barney style".. is there any modifications you would have to make to get the LO intake mani and throttle body to fit my 2000 2.4 LD9?

Yes. You need to modify the 2.3 manifold, a couple of the holes need to be re drilled . Your also going to need a spacer made to transition the ports together. The 2.3 and 2.4 have very different shapes on the ports. Search 2.3 mani swap. Theres tons of info on this swap

I can and will argue that, just get gasket from the year of mani and take dremel to it

But you can only shape so much. Even after getting the mani to line up via re drilling some holes it still does not quite line up right on the ports. I have a stripped spare head and you can look into the ports and see the bottom has a small lip and the top of the mani doesnt line up right. You would have to add material to get it to have a smooth transition. Im sure it would work but id be afraid of a vacuum leak.

Yes matching the gasket isnt a biggie. But having the ports not line up sucks

Subed because I'm interested



Paying someone to install parts and bragging about it being fast, is like watching someone bang your wife and being proud to raise their kids.

lol, its pretty easy to make the ports a little more equal, takes modding a bit but easy, there are acts on JBO about it, just mainly involves dremel, and ALOT of patience, then when your done you get to play with intake mani seeing as how its aluminum, you'd have to work with Aluminum, and then mold to the ports, or the most part you can get it pretty damn close with dremel, that tiny lip won't matter that much,if staying N/A, but i you can get right type of aluminum then you just measure and mold

You can get it very close I agree. But you still need to add material to get the transition to match. Im not sure how or if it makes a difference if it "slightly off' or with a lip. I would have a phenolic spacer made, it makes it so much easier. I like the idea of having a smooth transition into the head.
On the bottom it looks like you need to take off a quarter of a inch or so off the manifold. That also doesnt leave a lot of gasket left either after you match it.

no I mean if you know how to work with aluminum you will not need its a matter of removing and adding material where needed, I have ran all 3 manifolds on my car and used spacer and not, spacer only needed for direct port

I have the lo manifold on my 99' ld9 and i did not port match it and did not use a spacer just modified the 2.3 intake gasket and have had no issues with the setup.

^^^^you must have modified the manifold too, it does not just bolt up to the 2,4 head, and just because you can make it fit does not mean you are using it to its full potential. I still think the prorer way to do this is have a spacer made to transition the ports smoothly together, and a added bonus you wont have as much heat soak from the head either

Actually........................

HO isnt junk, all depends if its going on a stock 2.4 or not, a 2.4 with cams and other modifications allowing it to use the cfm that the HO manifold is slated to you will have bigger gains without question but if just bolting on and not changing cams or building a motor the LO would prove more bang for the buck

and if going boosted the HO manifold is going to help even further

even with putting bolt on parts onto the car retuning for something such as the intake manifold that determines incoming cfm of air would need to be done to have everything work together properly

I have not run the ho and lo on a bootsted motor as we all know I am N/A, and plan to stay that way for a while maybe just a bottle or 2 lol

yeah but higher compression, better flowing head, higher rpm limit and cams to support the previous items will yield better results with the ho opposed to the lo

I'm just gonna pick up a spacer from OEM for my HO manifold.
