I have a 96 Z24 and i was at a show today and saw another 96 Z who swapped in the HO quad 4 and was wondering if it was really worth the effort. i dont know the hp differences so. but if it is worth it i would definantly look into it so if anyone knows of a link for a walk through or tutorial that would be awesome
"sometimes the respect is more important..."
sure he swapped it in? he could of just swapped the ID plates and make everyone think he did the swap
Im a Xbox 360 fanboy...and damn proud of it!!
well stock u have 140HP and i think 170TQ and the ho stock has 190HP and 190TQ or is it 198HP and 198TQ i dunno but i think 190 for both but yea most people with the HO run low #'s at the track but do do a motor swap u will swap the motor and ECU and u might wanna swap the fuel pump if the HO is better but i dunno but i think the trans on the 2.4L and the 2.3L bolt right up with no mods....but i am just saying what i know i might be wrong or right i dunno
well he had the HO intake manifold so he might have just made it look like he did the swap but i think i wanna do the swap. wat about mounts and fuel, are they pretty much the same, and the HO is on OBD1 isnt it so would that be another thing to go around when i went to wire it up?
"sometimes the respect is more important..."
if you want to be sure if he swap it, check the chain housing. the Ho have a dipstick in front while the 2.4 have a dipstick on the back and the cap for the oil is on the chain housing.
89-92 Ho have 180hp@6200 and 160lbs/tq@5200
93 had 175hp
94 had 170hp
The mount for the 92-95 2.3 are the same as the 2.4 except the tranny.
you would like to use the 92 tranny for the swap. way better than the Isuzu and it has better gearing.
The Ho ran on OBD1 but you can use the 2.4 ecm but with some complication(IE- EGR, Cam sensor, ignition and a few other small things) and the rev limiter is too low.
If you go with the OBD1 ecm, you'll have to repin the 96 harness.
YOU DON'T NEED THE 2.3 HARNESS.
The Ho or W41 chip will be better with an Ho than the 95 chip.
You'll need the Ho fuel rail since it has 32lbs injectors and you'll have to modify the PS line.

2.3 Ho
what is the best car to yank the motor out of? an achieva has the ho doesnt it? isnt there a 190 stock hp ho? i have told there is
"sometimes the respect is more important..."
yeah, about 190 (at the crank)
You could even look for W41, 210(crank again) stock. They're in Olds Calais, I know that.

awesome i just am lookin to find some more info on the swap itself if anyone has any that would be awesome...pics....walk throughs...thanks guys
"sometimes the respect is more important..."
the Ho is 180-170hp not 190. The only 190hp 2.3 was the W41 for 91-92. 93 W41 was 185hp.
W41 engine came in some Calais 442 and in the Achieva SCX. only problem, they were not mass produce so you're better finding an Ho and swap the cams(witch is what a W41 is)
The Ho engine can be found in the G-A, beretta Gtz, Calais, Achieva, Cutlass Supreme
It has to be a 5spd. if it's an auto, it's a Lo.
Don't get caught by the Lo, you'll have to really check correctly to find a real Ho. The exhaust manifold is not a header style. It's a big cast manifold.

You're quoting Wheel HP right?

so does anyone have any links or anything on the swap itself from a 2.4 twin cam or what
"sometimes the respect is more important..."
crank Hp not wheel Hp. Wheel Hp on an Ho is between 152-157whp.

2.3 Ho
there is a BRAND NEW w41 on ebay rigyht now that mantapart is selling for 3000$
also i think it comes with a chip if you need one...
what about just swapping heads, would that improve the engine enough to be worth it...of course i would swap the intake manifold too
"sometimes the respect is more important..."
you have to drill some coolantg passage, the compression goes up to 11.4:1

2.3 Ho

Well, for starters, the only person that already spoke above that knows anything of what he's talking about is MFK-223. Secondly the hp/tq ratings he gave are correct and rated at the crank.
Now. I have done this swap, currently running in my 98 Sunfire. It will NOT be easy since your car is most likely OBDII. You do not want to run this engine off your 2.4 computer.
My engine is a 1990 which was much harder to swap(had to fabricate a mount on my 2.3 oil pan) and redrill some holes. Otherwise, if you take the 92 it will be a straight forward swap MECHANICALLY. You can use your stock fuel pump and fuel rail but you must swap the clips from your 2.4 injectors to the 2.3 injectors and put those in the 2.4 rail. Some modification to the PS line is required AND I took the coolant hose that runs under the engine from the 2.4 and put that on the 2.3 so it would match up nicely.
Obviously some imagination is required to route alot of the vacuum lines, throttle cable, etc etc. You need to swap out your current evap can for the non electronic one, a little fabrication there too. I used the 2.4 tranny as the 90 had a 282 external slave which I could not mount to the sunfire without alot of fabrication. I also figured the lower gearing on the Isuzu will just compensate for the lack of torque of this engine(in ratio to HP that is because its still has a higher amount of tq than the 2.4 but at a higher rpm). Also doing this enabled me to keep some 2.4 shifter cables stock instead of having to lenghten them and grind them out.
Use the axles you get from the 2.3, they have a bearing that bolts to the block which gives you equal length drive shafts(no or minimal torque steer).
The wiring I'm not even getting into but I tell you mine looks like a mess and took me many many hours of staring at the 2.4L, 2.3L wiring diagrams and to get my gauges in the dash going, the 92 grand am wiring. I say this because I was not able to use my stock cluster as it has a microprocessor. The only way you can use the cluster from a cavy/sunfire would be to swap your wiring with a 2.3L cavalier/sunfire, that cluster and then chip that computer.
I now have an analog cluster which has the 7000k redline, the oil pressure and voltmeter fully functional in my sunfire. The car runs like a champ(and is damn fast, 150+kmph still in 3rd gear and it gets there very quickly). I kept the stock exhaust manifold from the 2.3, it goes down to a 3" custom downpipe, 27" long x 3" exhaust that takes up the whole bump where both the cat/resonator used to be, all the way over the axle splitting in dual 2.5" for looks.
I kept some of the stock wiring(for lights, accessories in the car, etc) and ran some wiring/spliced for the engine, ignition, gauges etc. I am using some of the stock relays and some of the beretta relays which I've tucked under the hood. For me, this was a part time did it all alone with minor help and it took me shy of a year(but then again the car was stored all winter).
I can mention one stupid mistake I did that you don't want to repeat. When your swapping the bottom coolant hose from the 2.4 to the 2.3 you will notice there is a thermostat there. Take it out and chuck it far away. The 2.3 already has a thermostat and its on the left hand of the engine (where the coolant sensors are located). Don't ask me why they moved this on the 2.4 but I was initially getting no water running and wondering why
Hehe.
Disable any alarm horn before starting, they get annoying fast when you're splicing around and cranking every once in a while to see the outcome.
If you need any specifics, go ahead and ask me. I no longer have my server running(no internet at the new home yet) but I'll try and bring some pictures to work and host them on another server of mine to give you a headsup. Maybe I can eventually catch some sound clips, I think it sounds badass

yes i will agree most of this info has little to no backing in fact at all. worse yet a uninformed opinions with little to no backing. here are some if my thoughts. i would have been doing this swap but the forces that be didnt think i desearved to..
1. wiring back to 95 would have been WAY easier then back to a non-3rd gen J. also i talked to JBP and the can prolly make the HO work on the stock wiring (reflash for using crank for timing, account for fuel and redline, etc) so that makes it mostly mechanical swap. much less to worry about. just do some of the little things he mentioned.
2. yes use a 92+ engine. prefer to use 92 since its 086 head and double row timing chain and what not. i didnt find one but so is my luck.. which has gotten much worse
3. use a 93-94 (and some 92s) trans which is the NVG-T550. good gears set and much stronger than that crappy isuzu. i doubt the isuzu will like the 7000 rpm shifts since mine didnt like 5000 rpm shifts
there are also a list of things that will need to be done. the reason i had to research more is because i had no real help and because i am not as mechanically inclined as many on here or Q4Forums. this swap can be made rather straight forward for any 95-99 2.4 manual J. you just gotta do your homework before plugging away. i hope i helped.
Sven you totally quarterloafed your computer..
Here's a question.
What about swapping the head from 2.3HO into 2.3LO would you have to drill passages?
I wan't to swap as much of the HO(Or W41) into my engine as I can without a computer swap.
<img src="http://img.photobucket.com/albums/v502/brad_sk88/SigSummer05.jpg" alt="Image hosted by Photobucket.com">
you can swap any head from any 2.3 without any modification. You'll get more power yes but you still can't use the Ho cams. You can use the secret cams swap for the 2.4. Or find a good machine shop that could modify a set of Lo cams for the sensor pickup.

2.3 Ho
You're killing my post count
Why can't I swap them in, what am I missing?
<img src="http://img.photobucket.com/albums/v502/brad_sk88/SigSummer05.jpg" alt="Image hosted by Photobucket.com">
You have an auto so OBDII. You can't chip it. The Ho cams make power at 6200rpm and the W41 cams make peak power at 6800rpm. The rev limiter is set at 6250-6500 so the powerband is not too good with the stock limiter. The Ho/W41 cams don't have the sensor pickup. You would have to modify the end of the cam to fit the Hex for the Pc pump.
But you can use the Ho manifolds and the 086 head. it will give you more Hp of course. Somewhere around 10-30hp.

i'm assuming very worth it...
