quad 4 questions/info

[dohcfiend]

any1 know anything about the gm quad 4. i don't see many of them in the yard. they are 2.3l 4cyls right?

do they make good power? what are their power specs if any1 knows off the top of their heads?

i might get one to tear into it depending on a few things. I have heard they make good power and they don't have much aftermarket much like the 3.4 dohc.

wouldn't that be a slap in the face to the ricers, a geo storm, a geo metro or even a honda civic with a quad 4 in it that would tear them up?

i know it isn't really a 60v6 but there are good techs on here and i have heard other topics be4 about this motor.

or what is gm's most powerful 4 banger up to 97?

190HP and 180TQ I believe. The heads were problem prone. Might be a better idea to get a 2.4L instead. Same family but improved design. They came in early third gen Cavalier Z24's

190 hp was the w-41 engine. The HO engines were 170-175, and the stockers were about 140. The heads were problem prone, they tend to crack between the intake valves. The 2.4 added a balance shaft and had smaller valves and less lift with the cams. 2.4 was 150 hp. There was no HO option, they were ALL considered HO. Someone (Mantapart?) sells a stroker kit for the 2.3 making it a 2.5. I know that Mantapart sells brand new w-41 engines complete for about 3 grand.

The Quad was one hell of a 4 cyl. in it's day. Ran circles around the old Tech 4..., I had both in 87 GAs. BUT, the Tech 4 was known for reliability. I have had several, the best was in an 86 Celebrity Wagon. I used and abused the lil fuck till it hit 327,000 miles. Started it up and sold it for $100 to a guy who needed "basic" transportation. Nothing worked except the radio and the drive train. The only Quad I owned was in the 87 GA, and it was fast, but,....cracked a head, at 79,000. Overheated and locked up. YEAH TOAST!

190/180 i think that is more tq than a gsr motor. how do i identify a w-41 motor and what cars do they come in? if i even thought about it seriously a new motor wouldn't be an option. i was thinking 99 bucks at the yard. nice article a 230 horse 4 banger.

On the cam cover, it will say Oldsmobile w-41. I think they were in the 442's?

The Quad's didn't have that much torque. They were rated 160 lb-ft http://home.att.net/~csmalley/w41vsw40.jpg

yea the cam/coil cover will be red and say w-41,comes in cutlass quad442, old cailas(sp) and acheiva scx's,beretta gtz's and some ga gt's I think

[Doubt_Incarnate]

i think the cams are interchangablr between the w-41 and the newer 2.4 j-motor. if it wasnt an iron block i would check into it more, but if i have to have iron, i'm going or the 6cyl.

The W-41 was an Oldsmobile Only engine the Berettas and GA's only got the HO, regular output and SOHC engines.

You can mount a Quad 4 HO/W-41 Head Combo on the 2.4L. There was an article in Hot Rod or something like that a couple years ago w/ a guy using that combo and a turbo pushing 600+Hp in a Sunfire.

[X11_STE]

If you came find a "good" w-41 head (yea right!) them bolt it up to a newer 2.4 twin cam block and then you'll be running something like 13:1 comp. Not sure of any hp figures but if you could get it to run I am sure it would scare the hell out of any ricer that pulls up on you.

Whatever you do with the Quads, just don't get the "Quad OHC" or the 1995 model.

I believe all 87-89s are the standard output, the HO was available 90-94, the W41 was available 91-94, the OHC was available 92-94. All the Berettas are HO if they have the Quad. W41 was only available in Olds models. All HO and W41 cars are manual, OHC and standard output could be had either manual or auto.

i think the W-41's even had a thorsen LSD equipped gretag tranny.

i think the W-41's even had a thorsen LSD equipped gretag tranny.

Very few...probably less than 200. The remainder of W41 cars had open diffs.
