I drove my freinds 95 z24 last night. That engine rips way harder than the 2.4 twin cam I wish I had a 95 2.3 in my z24
Anyone know if you can buy a 95' 2.3 motor anywhere?
not to mention, dont they even have LESS hp than a 2.4?
Yep I just talked to him and he put a 94 gtz engine in it lucky bastard
The 95 z wasn't a HO hey?

Nope. And your friend is wrong on the engine he swapped. The GTZ trim level wasn't offerred in 1994; '93 was the last model year. '94s were called Z26's, and very, very, VERY few of them came with the LG0 (under 5% of total Z26 production). Meaning it's a 1993 LG0, or he's blowing more smoke than Lindsey Lohan during a traffic stop.

no...it was an LO quad4..about the same power as a twin cam....but the HO quad4 he swaped in can easily drop into any 2.4 equipped manual Jbody...but they are getting harder to find in the junk yards
I dunno check this video of a 95 z that sounds like it rips. Sometimes I think GM lies about the horsepower to me certain stat quo's

the 95 was a 2.3 with balance shafts but what made it a non-High output
I guess for the real 180 HP quad 4 you have to get a 89-94
does anyone know the numbers for the high out put models LD2 or something like that?

HO Quad 4s were different from the standard DOHC Quad 4 (there was also a garbage SOHC version) in their:
high compression pistons (10:1 instead of 9:1)
higher lift/duration cams
better flowing intake and exhaust manifolds
larger throttle body
bigger injectors
better flowing head
better gearing in the transaxle
And probably a few things I've forgotten over the years.

For 180, you'd need a 1990-1992. There was no 1989 HO, and power was reduced to 175 HP in 1993-94.

LG0 w/ W41 performance package (Oldsmobile Calais Quad442/Achieva SCX only), 190/185 HP
LG0 - 180/175 HP
LD2 - 160/155 HP
SOHC - 115 HP
Please note that the only engine to bear the "High Output" designation was the LG0. Neither the LD9 nor the SOHC are called "High Output", but are 2.3Ls.

LGO is the rpo code ..8th digit in the vin is an "A" ..easy to find from 89-94 ..lucky if you find w41 version..it made 190hp..
the HO made more power than the 95 for more reasons than no balance shafts..it had bigger cams,higher compression pistons,higher rev limit.smaller pulley, better flowing head, etc....
is the LGO the same as LGO-A?
I'm figuring the A stands for the A in the vin code wich represents it's a HO right?
the 95 quad 4 was nothing more than that, a quad 4. not a LO, not a HO. just a 2.3 quad 4.
The HO motor itself is a HO strictly because of the larger cams and pistons (the injectors might be larger too). The throttle body is the same, the manifolds are the same, the head is the same, etc. And yes it did get mated to a better geared/stronger transmission.

wow..so much wrong info...first off

YES the 95 was an LO...since technically there was no "low output" engine from GM quad tuners refer to the 155hp quad as an LO to simply make the differnce in it from the HO quad durring conversation..its just so no one is confused on which engine theyre talking about..i dont see how this got mixed up

thats almost right..the manifolds were not the same and the heads were no where near the same!!
the HO quad come with BIGGER intake AND exhaust manifolds and the HO heads had bigger valves and bigger ports
well, yes its a 'low output' 2.3, but its not the LO engine. theres definatly some differences.

Please Explain...
Because I have the exhaust manifold and an 086 head from 2 different LO motors from 90-92. I also have one out of the couple different designs for what we all call the "HO intake manifold" which we all know can be found on LO Grand Ams as well. What might be different in the head could be the springs and valves, but nothing else.

Well, the question that needs to be asked is, what are YOU calling an "HO intake manifold"? Aesthetically, the standard 2.3L intake manifolds look the same. The bore openings and flow will be different from a VIN D to a VIN A, though. Technically, an "HO intake manifold" is one that started its life on a VIN A Quad 4, nothing else. Now I'm not discounting the fact that there may be cars sitting around with them that didn't orginally come with them, but that's another story.
As for the 086 head on a VIN D, what I'd bet happened is that a previous owner had head cracking/warping issues and grabbed any DOHC head they could find at a salvage operation. To my knowledge, which like I said, has faded over the years, no VIN D Quad 4 left the factory with an 086 head. Yes, they will bolt up without problems to a VIN D, and the springs/valves would likely have been the same, unless they were used from the existing VIN D parts as well. There were no different "versions" of an 086 casting. If the eight digit number between the two cam towers ends in "086", then yes, you have the big swinging dick of Quad 4 heads (heh...mind, meet gutter).

lucky if you find w41 version..
If you do, buy a lottery ticket. There were less than 3000 produced over 3 years, meaning don't hold out hope for finding one.

All of this is justified by a burnout during winter on snow covered roads....simply amazing

I have been around long enough. You don't need to explain the differences of the HO and LO intake manifolds. And the 086 head was OEM for HO and LO for 90-92. And the exhaust manifold that mates to it is the same whether HO or LO. Perhaps you guys should spend a little more time on Quad4forums.
