I'm looking to buy an 82 240 GL. I new to Volvos just for starters. Before anyone says anything I tried searching the site for awhile but its hard to find things on here.

So i was wondering do the 240s come with a LSD or what models come with LSD rearend, if any?

Also I've looked into the engines and it seems that one can put a turbo on a non-turbo somewhat easier than other car types, wondering how hard the swap to a turbo would be on a non turbo and if it's even possible?

If anyone can direct me to a thread or post that could help me out it would be much appreciated!

Thanks in advance!

 

only some of the 760s, 960s, and later 940's have the locker rear end. its not a true limited slip, it locks to the two rear wheels together at speeds below about 20mph when one wheel slips. above 20MPH (or whatever the threshold is), it won't lock. and it doesn't do partial limited slip like more sophisticated system.

afaik, this was never put on a 240.

the easiest way to swap on a turbo would be to do a complete engine + ECU transplant from a turbo car, like a 740/940 T, along with the larger radiator, the intercooler, etc. me, I'd keep the 940T intact and drive it instead. 240 turbos are pretty rare.


turbo...

(1992 turbo 740...)

 

1992 740/940 turbo engine:


note significantly different air path, with air filter box behind the right headlight, turbo on the exhaust manifold, intercooler (not really visible) along the radiator, and rest of intake tract from intercooler to throttle body on the left side. battery relocated to left side, too.

 

24o's never had LSDs...
You can turbo ANY car, it just takes $... Always better to get an original factory turbo set up.
1982 can be Turbo or NA...

the turbo engines have hardened sodium filled exhaust valves, they have lowered compression ratio, and beefier cranks. they have a heavier duty tranmission, too (AW71 instead of AW70 on a non-turbo automatic, or M46 4-speed with electric overdrive on the rare stickshift turbos). They also ahve a heavier duty version of the rear axle (I think the designation is 1041, instead of 1031). 94/95 940 turbos have additional oil squirters to cool the piston skirts and reduce piston slap.

the turbos get lousy gas mileage. I average below 18MPG around town, and at best 22MPG on the highway. our non-turbo 240 gets 25 in town and up to 28-29mpg on the highway.

 

The late 92 and 93 240s had a G80 locker as an (extremely rare) option, which is the same as the one in the 940. To mount one you have to either use the right axle from a 93 240, or cut yours 1/4 of an inch. The G80 locker has a tone ring for ABS which has 48 teeth, 36 of which you will have to cut out to work. The previous posts are correct, however. It does only work up until 20mph.
I will be installing one in my '88 245 in the coming weeks, and to be completely honest I wouldn't suggest it to a novice.
Turbo swaps can be done very easily, I got everything I needed to run a simple +T setup for under $200 from my local pick-n-pull, with the exception being a good turbo. I bought a cheap one that needed rebuilt. You can +T on factory ECU and injection, but only at very low boost or you will have severe counts of knock as the engine leans out.
The BEST way is to use a turbo ECU, but that is a basic +T that will get you going.

 

the locker sucks when you're squealing your wheels on a hard tight U turn, it suddenly grabs and causes the whole rear end to lurch.

i've never felt the need on dry pavement.

its good in snow and mud, if you're driving smooth, slow, and steady, but these cars are pretty good that way anyways.

 

That's pretty much my thoughts on it. Unless you cut the weight and it just kicks in all the time.
I'm installing it solely for the benefits of loose terrain.

 

the innards of the punkin is pretty much the same between a 240 and 940 rear end as they are both based on the Dana 30, but the axle housings are quite different, as the rear suspension is fairly different on the two cars (different thrust bars, different trailing arm attachments)... so its quite possible you could transplant a locker from a 940/960 (the 960's are more likely to have them, but only the 960 wagons are live axle, the sedans were IRS and totally different)

 

They're pretty much identical, it's just that the driver side axle on a 91 and down 240 is 1/4 inch too long. Which is why you either replace it with a 92-93 axle or cut your existing unit. The 7/9 axles are too short.
