Default Locking Diff/Interchangeable Gears?

Does anyone know whether it's possible to lock the diff on say a '98 crv's real-time tranny? Thus, creating an awd system that's working all the time?

Also, are b-series tranny's including the crv's interchangeable gear wise? Might sound crazy, but like using gsr gears instead of the crv's?

Anything is possible, but that wouldn't be a great idea to try to lock the diff. Locking it would cause the clutch packs to overheat and fail too quickly.

I would guess that the gears are interchangeable, but it seems to me that unless you had major hp upgrades.

i would go for changing the gears because my crv revs at 4k rpm at 80 mph. i hate it wastes so much gas. i want longer gears.

and isnt there a way to lock the diff permanantly?
how is the rwd engaged? never looked into it.

Honda's are designed to be operated at higher RPMs. You aren't getting bad mileage at 80 mph due to the gears, you are getting the mileage drop due to wind resistance.

The rear diff is hydraulic. When the front wheels slip, the system senses it and engages the rear wheels. It is only designed to be used in short bursts and never for long periods of time.

Not quite. I've done a lot of beach driving and never had an issue with mine.

In your beach driving, you aren't spinning the whole time. If you were, then your rear diff would over heat and shut off until it cooled.

Well to be honest, reason is I was looking at possibilities to turn my 93 civic si into track car and giving it awd, thus locking the diff blah blah blah. But it's sounding like all ill do is burn everything up...

Then again, if i did install everything and kept the diff the way it is and what not, would i still benefit with track use? I'm not familiar on how the crv's real time system works, but maybe it would help? Or, it could just add pointless weight and be better sticking with fwd

I think for the time and money you would be spending on the conversion, it would not be worth it at all. The extra weight isn't that big a deal. But you could take the money you would spend on the conversion and put it to dialing in your suspension and get your civic to ride on rails.

Thanks. I think that making an AWD civic would be sick, but the CR-V diff/AWD system wouldn't be the right way to do it. There are plenty of FWD track cars that will handle with and run with AWD cars. It is an on going test though, to find the setup that works for your driving style and power output.

lol. Everyone has the grand idea to convert their EG or EF to AWD using either the CRV AWD system or the old Wagovan AWD system.

With that said, just how many of these frankensteins have you ever seen? Probably none. This should shed some light on how possible or feasable it is.

The Civic/Integra is a FWD platform. Leave it at that. If you want AWD, buy a car that already is from the factory.

lol Some of us can still dream. I know that my friend who owns an ep3 was looking around and they sell a custom transmission that's an awd platform just for the k20. I guess if I really wanted too, just go with the almighty k swap and hook up one of those mothers. Hell expensive though

I looked at some other threads with people mid mounting the engine to make a rwd car, but I just don't wanna hassle with all that custom fab. Though, I do have a friend who's doing it to his, so hey maybe he'd help with mine.

And the wagovan sounds like the better choice for awd options, but I was going to swap to a B series, and i doubt it'd mate. On the other hand I've checked out K swaps, a lot of money yes, but then the option would expand more for awd options probably. But yet again, probably a lot of custom **** that I'll have to figure out and what not

@supafil25,
thats the vid that i saw before.. i thought it was an EG but rather an EF instead...
i was looking into this "idea" for quite sometime even before this thread was made,
the shop that i go to here in my location is building a track car(autoX, circuit) i presented
them this idea... they wanna do it but itll take a lot of work hrs for them, they just decided
to sell me thier wagon, its a 6spd awd! d series though, but currently im finishing up my
EG as my weekend car autoX and circuit too! i might jump into that proj. if i finish
mine at an early sked than im expecting....
i just gotta find a cheap shell, i prefer EG... then probably hook up with the shop so it could
be a long proj. for the both of us...

May times huh? Just how many? And have you ever seen one in person?

Let's put it this way...how many B-series swaps have you seen? Now, how many AWD conversions have you seen? Probably none, just as I said before.

The point remains...this isn't something that can be done in the garage over a weekend or two. You need to do some serious fab work. And in the end, you have a car that'll get whooped up on by an STi or EVO.

Let's also not forget that the Honda AWD system was not designed to handle a lot of HP.

i have seen one at a local honda shop by me. and with a welder and some help i can do an awd swap in a couple weeks. its a lot of little things that add up to make it seem like an overwhelming job. and the only time the awd drivetrain wouldnt hold up is the launch.

So basically if you have the time and resources to do so, and AWD civic is fair game. The only thing is, the wagovan tranny/diff will only mate to a d series, not b or anything else. I've read that the wagovan can handle more power seeing as though its gear driven AWD and not hydraulic like the crv. I'm guessing that the inly option for the b series is the crv. What about something crazy like the k series in a civic? Seems like there would be more to choose from with the RDX, CRV, and whatever else.

if K series in civic.. probably a rt4wd system of a gen.2 crv??
thatll be too much..LOL
but if you have the re$$$ource$$..and wanna challenge yourself
or just be "different" the possibilities are limitless!

good luck to who ever is gonna go thru this path!

Well I'm assuming the gen 2 crv tranny would mate with any other k series right? I mean b series tranny's mate right up no strings attached usually, but would the k24 engine's tranny thatthe crv uses mate up with a k20?

or like that h22 with a b series trans you can fab up a B to D plate for the trans and run a b18 awd civic.

Really? Never really heard of that being a possiblity. Maybe with the h22 and the b tranny, but never a b with a d
