swap from 2.4L LD9 to a 2.3L HO
Friday, February 09, 2007 5:59 AM
My LD9 has a million miles on it and is starting to go out and I was wondering how to swap a 2.3 HO in for the LD9

will the 2.3HO bolt up to the 2.4 manny tranny?
will all the accessories (i.e. a/c compressor, altanator...) bolt to the 2.3HO or do I have to buy new ones?
will LD9 headers bolt up?
and
can i use the LD9 ecm?

any help would be greatly appreciated while I search this site for information about what I'm looking for

thanks in advance

or is there another swap that i could do that would benifit me?
or should I just stick with the 2.4LD9?

ok thanks, but I've found a forum elsewhere that states that the A/C compressor bolts up so I figured maybe the alternator and everything else did too

does aynone know if the water pump on the 2.3HO specifically the W41 is run by the timing chain?

All Quad4/Twin Cam motors (2.3L/2.4L) run the water pump off of the timing chain. Some HO/w41 use a double roller timing chain, so the water pump gear is most likely going to different for that particular motor.

whoa i didnt know that... i wonder how hard it would be to get that setup to work on a 2.4.

gary, i would say just stick with the 2.4 and go ahead and do some of the hybrid swaps, ie the oil pump, secret cams, maybe even do an .086 head.




UFlip06 said it best: Just look underneath the engine and if you see big hairy balls it's a 2.4 Twin Cam, if they're shaved it's an Ecotec and if you see nothing it's a 2200!

I wouldn't...but it definately gives you a better understanding of your motor.

well the only reason i was thinking about doing afull engine swap to say a w41 or another 2.3l HO engine is becuaseI've already got 150,xxx miles on the LD9 and it's looking like the block is cracked but I was just tryin to get info on the 2.3L HO swap causeI've been looking for a W41!

its not as difficult as some make it out..i dont think the alternator will fit..but if you go looking for one get the 95 and 95 ONLY alternator..itll bolt up AND plug into the wiring harness
itll bolt to your trans yet..even though the getrag that came with the HO is better and faster
will your header fit ..no...but the stock HO manifold flows better than a 2.4 header...i gave my stock mani a mild port and got the collector out to 2.5"..i think its 2.25" stock iirc
power steering is an obsticle...youll need to use the power steering that comes with the quad since it runs off a pulley and belt..unlike the 2.4...other wise most stuff bolts up and would be just as easy to install as another 2.4..only the end result is MUCH more fun

If you would like to find out, you could try it first hand...I found this today

uhm holy crap THAT is badass! i dont see a problem with it working either, unless for some reason the 2.4 timing chain cover wont be wide enough, but it looks the same size at the 2.3, just shaped a little different in places.

omg why are you guys thinking backward?
turning your single chain(that works fine) in to a double chain will only add weight..making it harder to rev and a loss of power

Does not make sense. How do we know this?

have you ever compared the ports,runners,and collector or an HO exhaust manifld to a 2.4 header? if not perhaps you should ask ANYONE with a quad4 why they never even TRY to fit a 2.4 header on their engine..

No I truly have not. That being said a factory manifold will not have a bigger collector than a aftermarket header. So it sounds as if there is no real prrof that it flows better? Just opinions. not saying you are wrong, you could be right, I just do not see it.

knowing the runners and ports on an aftermarket 2.4 header are much smaller than the stock runners and ports on the ho manifold are enough proof for me ..the early HO manifold had a 2.5" collector as well

True. But there is no aftermarket header yet designed to fit in a 3rd Gen (except for custom). Scott is comparing a HO manifold to a 2.4L header...not a 2.3L header (which TRS has already proven to increase power...and by a great deal). I thought Scott (You^^^) or Hotbug were in the works for designing one for the 3rd Gen J-body. Whatever happened to that?

On a side note, the Early quad LO motors had a real 4-2-1 stock header, but it flows like crap. So just cause it's a header doesn't automatically make it better.

I'm not thinking backwards...Brad was obviously intrigued, so I showed him. I currently am researching timing assemblies from Honda, Dodge and Ford DOHC motors, and seeing if any of their belt driven timing components might be able to be modified to work for the 2.4L. I don't have high hopes, but it doesn't hurt to look.

mantapart sells a conversion set to run a belt on the 2.4, i think its like 950$!!! lol

as for the exhaust manifold, when you compare the 2.4 header with the 2.3ho exhaust mani, you can clearly see that the 2.4 header on that engine will hurts your performance.

well there you have it lol ..and yes ive seen belt conversions out there..i know of someone that has one for sale for the 2.3 engine but it will not fit a 3rd gen cav..only N bodies..mounting issues..so i would like to see someone actually make one to fit our cars..i would be the first one to buy it

still working on that..the local company idea kinda fell thru when the price got to high for me to offer anyone and they didnt want to work with me anymore..so now im working with a jig to design one myself..the project hasnt died dont worry!

Stick with the 2.4..youll be saving money in the long run..with trying to swap over your going through to much hassle. just take the car, get another 2.4Ld9 motor, swap over the mods that you can and go from there..

Explain yourself.

If he wants to swap a HO or w41, he obviously wants more power. It would cost at least 3x as much and require 10x as much work to modify a NA 2.4L to keep up with a HO or W41. And by the time he is done, the majority of his motor will be from a 2.3L motor anyways.
