Local yard I found an Achieva with a real 2.3 quad HO (IDI Cover currently on my Z, lol). Now I may just buy the whole car and restore it, since it is new and nothing is off it or hit. If they dont have the title what exactly is desireable off it, the cams, crank pulley, head, intake/tb. But what else? The car is not a W41 but still a real 5 speed 2.3 quad HO and doesnt feel like the tranny is all there. I have to check the car out more but it will only go into 1st and second. I am thinking the linkage might be bad or it is siezed.

So anyways my question is, what is desireable fo use/resale?

Once again, Achieva 2.3 Quad HO Coupe 5 Speed.

Thanks
Chris

It depends on the year, if its the 95 (or 94 maybe), then its one of the lesser HO's I believe. Gilles will be the guy to talk to about that.

Buy stuff from CarCustoms Ebay! Won't be disappointed!

shifted is right..its gonna depend on the year...check the casting on the head..if its 086 then take the whole top end...if not dont bother
check the tranny..if the tranny ahs TWO mounts then you can use it(if its still good) once again..knowing the year would help us alot..almost all the parts are desirable to SOMEONE ...intake manifold and TB..exhaust manifold maybe..crank pulley , injectors, cams try to get the whole thing for a good price

go re check that vin number...I don't know of an HO powered achieva..they were either LO or W41...if the 8th digit is a D...carry on not much special here....head might still be an 086 head....even though its LO..happened a lot...753 is a good head too. If it's an A...thats a W41 car....another way to tell is the metal plate on the core support...it'll say W41...if its an HO it'll say W40...hope i helped

The HO manifold I got was from an achieva no idea on the year, also got a LO from a 95 achieva.
I went back to get the O86 head and it was GONE. So was the engine.

M45 + LD9 + 4T40-E, GO GO GO

Desirable for use
Everything

For resale
Probably everything except the crank

The last Ho was in 94. You need to go by year.

086 head - 90-92
Ho manifold can be found on Lo's and Ho's
VIN A are for Ho's and W41's. Ho's and W41 came only in Auto
The ONLY good crank pulley are the 90-91 Ho/W41 pulley.
The Ho exhaust manifold (the good one) only came in 90-92

Only the 086 head is desirable for a 2.4 owner. The 753 head is not worth is.


It all depend on what you want to do. If you want to resale something, the injectors, manifold and cams are worth it. The rest is soso.

Also, power wise:

90-92: 180hp
93= 175hp
94= 170hp

2.3 Ho

gilles got one thing backwards...HO and W41 never came auto...not only in auto haha...he knows his stuff though, he must have just had a blonde moment

Gilles...did achieva ever get an HO? i thought they only got W41?

Wow what I mistake I did. Ho's and W41 never came in auto.

The Achieva had all 5 quad. Lo, SOHC, Ho, W41 and 95.



Gilles
2.3 Ho

did the HO come in the SC then I take it??? does the achieva have the RPO plate on the core support like the calais does?

The Ho came in the Sc. I don't know about the RPO plate tough.



Gilles
2.3 Ho

The car is an SC, I know that and I think I saw 1990 or 1991, I am going back this week for everything. Regardless I am getting the injectors/cams/intake/tb. That I know, should be good resale I was also wondering if it is an 086 head if it would benefit my car.

I am GM SCed and if I swapped heads the ports would be different but I could use an adapter flange if the head is better. Also I want to bump the compression on my car (Currently 9.0.1), so does the HO have diff pistons or a diff head to raise compression?

So what would you reccomend, if it is an 086 with the two tranny mounts should I buy the whole engine cradle?

I will get an update on the car.

Both the quad 4 and TC have zero deck height and flat top pistons, so the main difference is that the 086 has 48cc combustion chambers and the 2.4L has 61cc. The quad 4 displaces less air, which is why it has a compression ratio of 10:1. With your 9:1 pistons on the LD9 and an 086 head, you are looking at 10.7:1 CR.


And yes, the 086 will benefit anyone with an LD9.

Brian, you are partially right.

Both engines have zero deck height and the 086 had 48cc combustion chamber and the 2.4 had 61cc.

The 2.3 NEVER had flat top pistons. The Ho pistons had a 7.5CC dish while the Lo pistons had a 11.3CC dish.

The change in compression is not all about the head. Displacement, combustion chamber size, deck height and pistons change compression.

When an engine move more air (more displacement) is has MORE compresison, not less like Brian said. 086 head on a 2.4 (96-99) make compression go to 11.4:1. 99+ 2.4 will have a compression of 11.7:1.

The 086 head flow alot more than any 2.4 head. Yes it will be a benefit for you but you'll need to tune it well to keep the Sc on it. The port's are different (witch I didn't need to tell you) but workable. You could port the Sc port to make them like the 086 head. I'm sure you can work your way to make it work.

The engine and trans together would make a great setup to boost if you want to play with Hptuner. You would start with an engine with 180hp plus the Sc.



Gilles
2.3 Ho

Well I bought everything, engine/trans/CV shafts/ basically the whole front of the car.

Big stuff

1992 Olds Achieva SC
89K Miles
5 Speed
Complete, woohoo!

What are thoughts about what I should do with it? I have HP tuners so that wont be a prob, I was thinking about swapping the heads but then what about the cams, I have the secret swap now could I use the upper half of the motor on my current motor? What would have to change? I think I have a lot of research to do.

Also I know I can use the trans being that it is a two mount to hold all the power I will make.

Or does someone want this 2.3 Quad HO with 89K? Make offers, lol.

Thanks
Chris

nice find man, you dont see many of these deals lying around in the yards anymore, especially with EVERYTHING intact. what did you end up paying for it all?

if you decide to go ahead and use the head...
make sure you get it checked for cracks and warping.. if all is well, i would get it decked a TINY bit just to square it up.

to use the cams, the exhuast would be fine-no modification needed (except for your hptuners)
as for the intake cam... your going to need to have it machined to accept the power steering pump hex shaft in the end of it, as well as (i think you can?) have the cam sensor grind in the center machined to work with the sensor. for the record ppl...does the HO intake cam have the same grind in the center as the 2.4's and the 95 2.3's? or do you acctually have to add material (is that even POSIBLE?) to it? somebody chime in on this one and explain. thanks.

lol, does anybody else think its weird that the 2.3 HO head's intake ports look similar to the 2.4 head's exhuast ports? and the same goes for the 2.4 intake ports being the same shape as the 2.3 exhuasts! lol, just weird and annoying if you ask me, it'd be a ton easier for all of us to swap parts if they woulda just stuck to at least the same frickn shape.

I would be interested in the head and cams, depending on the price. Been researching the 086 head swap for awhile now. Just waiting for the money to come in. I guess I would take the header if you got that as well. Again it all comes down to price, nothing new on this forum, as i haven, been saving long. Nice find.

the windage tray and bracket is worth pulling off

Chris, If I was you I would swap the whole Ho and trans. Since you have Hp you can tune it well.



Gilles
2.3 Ho

who wants a quad-4!

as if the oil pumps better

one thing though, if you made a "adapter plate" none of your brackits would line up, and your belt would be longer, and probly, the charger would hit the rad. suport.

Sorry, I don't think I explained myself very well.
I meant the physical displacement and not necessarily the amount of air that is moved into the cylinder (2.4L vs. 2.3L). Thank you for correcting me on the pistons though, I don't know what I was thinking.

It wont plug in though, I need the harness right?



http://members.cardomain.com/vertz24 1998 Z24 Convertible

No you don't need the harness.

IAT, Knock, MAP, oil pressure, O2 and CPS.

IAT is the normal 2 plugs

Knock is 1 wire

Map is 3 wire - can use the 2.4 one since you just need a piece of hose to connect it.

oil pressure don't need to be pluged

O2 is 1 wire but can use the 2.4 sensor

and Cps is 2 wire like the 2.4.



Gilles
2.3 Ho

Let me see if i am reading this right. Gillies, and others, you are saying i can put an HO Quad in my 2001 Cavy and it will run off of OBD-2 (with HPtuners) and run my Getrag trany? Where do i sign up? We swap so much from the HO motor to the LD9 anyways why not just swap the whole motor!

PSN ID: Phatchance249

What about mounts? Not only the engine mounts but what about that goofy PS pump? there has got to be more to it. Also if my car is a 1998 with HPT will I do okay? Also with the tranny are the sensors the same? and what about the front mount, the back looks the same but front looks different. I am picking up the motor on Saturday and cant wait to start cleaning it up. Funny thing is I saw the car get dragged into the yard about a year and a half ago saw the quad 4 emblems on the side and thought nothing of it. Car was virtually untouched except for the wheels were taken, not even the air box was touched.

My pistons and rods wont work in this motor will they? If I could swap over my eagle H beams and je 9.0.1 pistons what would my CR be?

Also thinking about swapping the head (If not whole motor) since it has no egr I should be cool right? also for the head I could just have it machined and weld a little to build up the aluminum correct?
