Ok, i have a 95 sunfire, and it sucks balls. Its slow, and sluggish.

I have the quad 4 (unfortunatly i guess. i keep hearing nothing good about it), but I hear there is a 2.3 quad 4 thats fast.

What is the 2.3 H.O. and how can i get it in my car? sounds like a newbie question, but till now ive stuck with the GM V8's and the honders. great combo i know...
This sunfire is ment to be a beater, or a quick seller, but i kinda like it... shhh, dont tell any of my honda friends.

I need a quick rundown, so i can go check out this motor monday out of a bereta gtz. it is in not running condition, but maybe i can pull it for parts, along with other items.

Also whats the big weak point on a stock quad 4?

the 2.3 ho is a high out put 4 cyclinder just as the name says, makes 180 h/p.
what else would you like to know

weak points would be head gasket if not taken care of properly


cavaliers been laid to rest
The saturn is being born
a new cavalier is in the mist

can i just put a 2.3 h.o. head on my quad 4? do i need to change anything?

cams head computer exhaust intake , remove balance shafts

easier to swap a older 2.3 HO in to your car

what i would do is get a 92 HO (180HP) or 92 W41 (190HP) for several reasons and then get the 93-94 new venture trans to go with it. a guy on here with tht combo runs a mid 14 with his 95 cavvy. also whatever engine you get, get the chip to go with it. mantapart makes one, and some others do as well. for a 95 2.3 manual its a very easy drop in swap.



Sven you totally quarterloafed your computer..

are you an auto or manual....auto's require some ecu/harness swapping, and is a little more extensive...if it's a manual, its a direct bolt in, and then you just need the ECU to run the bigger motor/injectors

There are a lot of differences between the normal 2.3L, and the HO 2.3L

HO Flywheel is lighter (HO's are all standard shift)

LO Cams - .360 lift (95), .375 (90-94)
HO Cams - .410 (89-94)

LO Pistons - 9.5:1 compression
HO Pistons - 10:1 compression

Cylinder heads..there's about 5 or 6 castings, casting numbers ending in 456 and 955 are popular, but suck. You want to go with an 086, or 755, those are the higher flowing of the cylinder heads.

If I was you, I'd make sure that motor turns over in the beretta. Put a wratchet on the crank, if it will do a full turn, go ahead and snag it for less than 100 bucks, anything more then that, tell them to kiss off. A lot of times either a head gasket blew, or the timing chain tensioner went out, and screwed it all up. Either way, you need a block to build from. I would try car-part.com and see if you can find a working motor fairly close, and rebuild it, more stuff you can use. This should get you started.

That mid 14 second cav he speaks of, I have driven, he is running an 086 head, and new rings on an older HO motor, his was 5 speed and it dropped right in. He also switched in the HO manual tranny, but that was a little more involved then the motor, I'd focus on the motor first, and then maybe switch the tranny in, the older HO tranny is far stronger than the isuzu that's in the 95-99 5 speed J's

is there a aftermarket exhaust manifold available for the 086 head?

i know of a w41 for you to swap in for $1200. want info? e-mail me




I was a retard, and now I'm permanently banned.

only header for the 2.3 is for the N & L body. you can always get an Ho manifold and port it.

2.3 Ho

the N and L body headers won't clear your firewall if I remember right...

the 086 head/manifold that matches it is very free flowing, and really you aren't likely to outflow that manifold, it'll more than suffice.

So a W41 or HO will bolt right into a 95 Z24 5 Speed ? Without changing out harnesses or computers ? I dont think that is correct. I can get a 95 Z24 witha blown motor right now for 500.00 its in really good conditiion also. Please let me know what I can do as far as another engine. I would love to swap in a HO or w41 but I don't want to have to change out the whole wirings of the 95 , if I have to get another 95 motor than I guess I will just do that. Any info on what I can do?

ok ..lets clear up some things.....
FIRST..IF YOU HAVE A 95 manuel CAVALIER you DO NOT need to change ANYTHING with the ECU....period
yes.manta makes a chip that will cut off your govenor and raise your redline,simply cus the HO can benefit from a higher redline cus of the cams...but the HO WILL work on a stock 95 ecu...
SECOND..a header for the 086 was mentioned and someone said that the stock manifold will suffice...no completly tru...were as the stock manifold IS nice and the LO can benefit from it a dyno test was run on a stock HO engine with ONLY the header changed with the one from www.the-race-shop.com and gave a 20hp gain ....by only changing the header!
as far as the tranny goes...i would recomend getting a 92+ tranny from a HO engine...beware of any of them before 92...the gear ratio was differnt( which isnt a biggy) but the MOUNTS are a biggy...and they were different before 92....
..............anything i miss???


THE GUY SURE LOOKS LIKE PLANT FOOD TO ME!!!

the engine has to be 92+ to fit in the cavy. only downside is that only the 89-92 Ho had 180 hp, 1993 hd 175hp and 1994 had 170hp.

another thing, if you swap from the 95 2.3 to an Ho, you need both manifold for the Ho to run correctly. If you take the 95 exhaust manifold, it's useless to use the Ho engine.

It need at LEAST the Ho manifold to work correctly otherwise you won't have any power over 5000rpm.

as for the header, like said above, it doesn't clear the J body firewall unless you have a second gen like SVC. and it's SVC that dyno the header.




Gilles
2.3 Ho

just for reference gilles the pre 92 HO engine Will fit in the 95 cav...i personally started with a 1990 egine / transmission combo...its those damn mount setups that makes it a pain...it has a front engine mount instead of a front tranny mount if you remember...thats why the 92+ tranny is important.....but hes right about the manifold...dont get any of it if you dont get the manifolds with it.....youll need to KEEP your cavvy top tranny mount and youll want to use the front mount that comes with the tranny you get...if that made sense lol
oh...and i just got off the phone with josh today about the new header for the HO...he said it wasnt "clearing" the firewall that was the problem but that it has never been even tested in a 3rd jen jbody to see if itll fit....hed like us to hold orders untill he gets a chance to fit one in...which is understandable lol..but for those kinda gains Im willing to wait!


THE GUY SURE LOOKS LIKE PLANT FOOD TO ME!!!

How about a 2.4 motor? will that be a problem to put in to the 95 with stock 95 computer? if not then i Would also like to know what needs to be done in order to accomplish it. Sensors should all be pretty simalar. I know it would also have to be a 96 to 99 if it was even gonna work at all. Any info on the 2.4 swap into a 95. Thanks again for the info ^^^ above guys.

in order to make the 2.4 swap work you will need a WHOLE 2.4 ecu and wire it up...not that complicated...but then again why swap an engine in that only makes about????....5hp more??? PERSONALLY i would go with the HO swap...thats what i did anyway...or if you wanted to make some real power just swap the head(and everything that comes with it),get the chip , and your all ready for the turbo ....i think lol


THE GUY SURE LOOKS LIKE PLANT FOOD TO ME!!!

you're crazy if you swap in a 2.4 over a 2.3. There are like less than 10 2.4 heads in existence that flow more than a stock 086 head...SunfighterGT is one of them, and anyone that owns an RSM head outflows a stock 086 head...catch the drift? With that much more flow up top, imagine how much bigger your turbo could be...how much sooner your spool would be...500 bucks is a steal...go buy that car, drop in an HO and have a blast

Look up Cavfan1, I drove his car, I screwed up badly, and drove a 15.3 first time driving the car, he drove it to a 14.5@100+ the car is fast, and HO's have a much better power band then a 2.4 IMO..

To swap in a 2.4 you'll have to upgrade to OBD II, and that's not easy...its not hard to go backwards...but going forwards is a whole nother story..swap in the HO and tell us how much you love it

So, let me get this straight. If i have a H.O. motor, i can drop it into my 95 manual sunfire without a problem, or switching ecus? How about trannys? Can i just use my stock tranny on a 2.3 H.O.? I dont care about gear ratios, or speed realy, i just am having problems with my motor and a rod knock. I went to replace the bearing today just to find out it was already replaced once, and when i put in a new bearing of the same size, it sitll was loose.
Now the old bearing wasnt bad, and the journal isnt scored or scratched, but i think it was still the wrong size.

Anyway, im tired of messin with it, and i have a 2.3. HO available.
I just want a plug and play.

does anyone have the rsm head?

the rsm head is like a 20x the cost of a 2.3 swap...why not just swap in the 2.3? lol

HO motor is a direct replacement in a 95 5 speed J car (sun and cav) drop it in, and enjoy...

Completely plug and play, well the P/S needs changed or the cam tower and cam need to be a conversion set. But other than that it's an east swap, had mine in, in about a weekend. Saturday got the motor, and had it in, and Sunday I got it all hooked up, then I had to get some new O-rings for the fuel system (a good suggestion)

awesome advise guys thankyou . If I can come across a ho motor i would be in busijness. Getting the car is not a problem. lol

if you can turbo a 2.4 as fast as yours...swapping this motor is cake

would I need anything else to put this in a 98 cav? or just the same as what's listed above?

I should be able to get my hands on one of these engines in town I just need to know which one is proper for the 98.. will it have any difference from the 95..it says direct swap..just wondering if it's the same for a 98..h and it's manual
