Wasn't having any luck in Maintenance so maybe the 3rd Gen is the place to try. Sorry about the double posting.....
I have a 95 GT with a Quad 4 in it thats toast, how much work is it going to be to put in the 2.4 out of a 1999 Grand Am. I have the complete working car, I am just wondering whats going to be involved. They are both automatics by the way.
I am sure the motor itself will just drop in and the harness will plug in, but what about the computer(s).
If anyone has and insight on what I am about to undertake let me know. I could sure use your wisdom.
I think I need to pull the Motor, Wiring and the ECU, Correct? and it should work. Just looking for any precautions or anything. I think the 95, it being an automatic is OBDII/OBDII Compliant
Any help at this point would be greatly appreciated.

Thats what I was hoping I wouldn't hear...
The problem is, i don't have a grand to fork out and i need the car on the road...all the yards want 1200 for a barebones 2.3, so thats kind of outta the question for me, theres hardly any left on the road here

Also, what about using the sensors from the 2.3 on the 2.4 or are the two motors that much different?
Why would you need the car back on the road so quickly if you've got a fully operational 99 grand am there to drive?
grand am isnt operational, no papers, and the brakes, knuckles, suspension and everything needs to be replaced for inspection...
Hum sorry but an engine is not OBDI or OBDII. The computer is. It's an easy swap really. Same mount, tranny bolt to it the same way, couple different sensor but can be easily changed, diferent IDI but you can use the 2.3 IDI.

2.3 Ho
Ya, I know its the computer and the wiring isn't it, thats why I was asking, if I swap to the 99 GA computer its not going to be looking for missing pieces is it?
I know it will drop right in, but can I change the sensors and have it run on the 95 computer or is it really going to be a pain in the ass?
I am worried that if I swap to the 99 computer alone, it is going to be looking for the cluster and ignition for passlock which the 95 gt doesn't have.
The only thing you should use from the GA is the engine. Use the 95 ecm to run it.

Thats what I want to hear. I was just a bit worried there were going to be a few extra sensors on the 99 2.4 that I didn't have on the 2.3 and wouldn't let the ECM run it.
Ill let you know how this pans out, if it doesn't work, I'm not out anything except my time, sold the rest of the car for parts for what I paid for it and I get the Motor which I can in turn sell as well...
From what I have read so far, the 99 is supposed to be smaller, advice given, drill and tap the hole to fit the larger one...or rig it with a nut on the side of the block?
I guess I was mistaken, that was the suggestions for the knock sensor....
I looked up the part numbers for the CKP sensor and connector and they are the same for the two motors. So thats ok....

1200 for a quad4?? wow..they arnt going to sell that lol ..you can get them MUCH cheaper...have you tried www.cat-part.com ?
anyway..yea these guys are right..the engine will bolt in..use the 95 pcm and wiring..and use the 2.4 sensors..they SHOULD for the most part plug in the same(even though the sensors are differnt) the harness plugs should be same..if not just splice them in
..its a shame about the quad though..what happened to it? headgasket?
Ya, I have checked, alot of the yards only have quads for core engines, and the few that still have one sitting around are charging outrageous prices for em, I went to my cousin who owns a service station nearby, he laughed at me and told me good luck finding a running one.
The quad, well its just going all to hell, I bought it cheap, with the motor as is. Ill keep the quad and tear it down, it may end up back in that bay some day..
Thanks for the help...
Ugh, I am stuck again, before we dropped the 2.4 in, we were looking over the lower dogbone mount which isnt on the Grand Am 2.4, and the bracket from the 2.3 Quad doesnt work.
On the 2.4 the A/C mounts directly to the block, and the quad A/C mounts to a bracket. I have attached a photo of the 2.4 block to show how he 2.3 bracket gets in the way of the A/C and that there is only one hole for the bracket to bolt onto anyway.
Does the 2.4s use a different bracket than the 2.3 Quad 4, or do I need to drill/tap this hole and cut off/do away with the entire A/C system.
Does anyone have a picture possibly of the 2.4 block and mount?
Anybody have any insight on this?
I am trying to track down a 99GT so I can climb under and check it out, but for some reason I am having a hard time. I think I am going to put the motor in without the lower mount/bracket and make sure it will run before I start cutting.
Nevermind, the mount for the 2.4 J-body mounts to the front of the motor versus side to side. Makes more sense now.
Now just to find one...
see..
..you just needed some time

I tried all the local junkyards, pretty hard to believe none of them have a junked j-body with a 2.4, or even the motor sitting in the warehouses.
Dealer wants $90 + tax for it.
Unbelievable, and on that note, anybody got an extra one?
