Just going to ask the questions straight up and not explain more than I need to.

This is for a CRV shell I bought recently.

In a B20/VTEC putting out 600 horsepower to the flywheel, how good would a CRV transmission hold up with the appropriate clutch and flywheel?

How is a CRV engine mounted, longitudinal or transversly?

How well do the CRV's transfer cases hold up? (please give your guesstimate of how much power they can hold).

Since they are both B-series, can you replace the CRV gears with ITR and GSR gears?


When performing a B20/VTEC conversion using a B16A head, what ECU do I need if I want to stay 4WD?

Where can I get a USDM CRV transmission and transfer case(s)? No luck from local yards.

Last question is....

What for AWD CRV's, and 4WD CRV's?

Thanks for the help, don't flame me for the car I'm fixing up.

Maybe, I would think that the transfer case to the rears would be weak, as well as the axels.

How is a CRV engine mounted, longitudinal or transversly?
Just like every other older Honda motor

How well do the CRV's transfer cases hold up? (please give your guesstimate of how much power they can hold).
I wouldn't put more than 225 to em

I've done it... have not ran it yet. I don't know what to expect.

Chip the CRV ecm
Where can I get a USDM CRV transmission and transfer case(s)? No luck from local yards.
do a search in the classifieds or on parts trader. Maybe call some yards on the west coast
Last question is....

huh??? I don't get this one.

axles are taken care of already.

What can I do to make the transfer case hold up to that kind of power other than having a whole new case or new gears custom made?

Last question was what years were the AWD models?

That is a good ? One that I have been thinking about for some time now, and have only answered it with A- custom gears B- 2wd conversion
Last question was what years were the AWD models?
I want to say 97-99, but I'm not sure </TD></TR></TABLE>

all the cr-vs have "awd" that are so equiped. there was only awd and 2wd available.

Then what is the Realtime 4WD?

Elementzil

Realtime 4wd means that it is in 2wd normally until it feels a wheel slip and then it kicks into 4wd. It is not something you can change yourself. I know for sure that the 2002 and 2003 CRV's have it and the 2003 elements have it.

So how effective is it when you do a 6k launch on street tires, say something sticky like Kumho Ecsta Supra 712's? Will all the wheels get power effeciently?

Anyone have a site about Realtime 4WD?

bryan305

you're going to launch a crv at 6000 rpm

bryan305

oh yeah...

jdmotorsports

i know when i get on sand and floor it the front wheels spin for a second then all 4 wheels kick in. my cr-v is a 98 and has the "realtime awd"

Aquafina

No, it was an example so I could find out how effective Realtime 4WD is.

How that site explained Realtime 4WD...

<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote &raquo;</TD></TR><TR><TD CLASS="quote">During traction loss on the driven axle (could be front or rear) a fully automatic system (hydraulic, mechanical or electronic) routes torque to the axle with traction. This means you have to completely lose traction in 2WD on your driven axle first and THEN the other axle will take over and try to keep the car moving. So, for a moment you have 4WD. Doesn't mean much because only two wheels have traction. Once the driven axle regains traction and both axles rotate at the speed again, the system moves back to 2WD.
</TD></TR></TABLE>

So if I launched at 6,000RPM, it wouldn't be gripping like, say a WRX does with all four wheels?

bryan305

it takes a moment for it to transfer the power to the front...so you would slip for a bit.

SI_DRIVR

I own a 2003 CRV Realtime AWD is exactly what the other thread said. Its front wheel drive, but when the tires slip the transfer case engages 4wd to give you better gas mileage. You can put a ITR or GSR tranny on the motor, but you'll have to modify it for 2wd only and cut a hole for the shifter. If you think you can use the Realtime AWD for hard launches with alot of horsepower then your going to break tranmissions like they are going out of style. The only good think about the CRV is the larger liter block. you can put v-tec on the engine, but the tranny won't use it well, cause the stock tranny is always in 2nd gear unless you do a swap the ECU will have to be chipped or the use of Hondata. A lot of work needed to make the CRV fast.
If you want your CRV fast then you have a lot of work ahead of you. B20/V-TEC, Tranny swap to 2wd. Lower the suspesion using I think accord coilovers.
You will never have the awd like a WRX or DSM does EVER!!

advanracing62

I've launched the CRV @ 5300... it spun the fronts for a sec, then gripped and off I go. It bogs alot though, mainly cause it's still the stock motor with a few minor upgrades. I cut a low 17 in it already, will be shooting for 16's this season, and then it is time for FI.

SI_DRIVR

I've had mine spin tires a little and launch hard, but the tranny still will not hold up for FI your going to have to get a tranny swap. The simple v-tec conversion will handle it no problem, but FI is going to take a lot more work and the gears are too close together without doing a tranny swap the power will be pointless.

I don't want 2WD, I want 4WD, otherwise I would have got something else.

SI_DRIVR

I'm just saying that if you had 4wd and over 250hp then the tanny won't hold up without a swap to 2wd or a fully built tranny and thats big $$$$$

Dave421

Sorry but the CRV's axles and rear differential will not hold up to much power. They simply make very expensive noises. Any B-Series tranny will bolt up to it but then you're back to 2wd. As for switching the gears and keeping the case, that shouldn't be a problem. You pretty much have to have the rear diff & axles custom made in order to take something insane like 600hp. As for the 4wd/awd debate, NO CRV HAS 4WD. They all have AWD (or 2wd). The 4wd label on the rear really isn't accurate as you cannot manually engage it. The 2nd gen. CRV will engage the rear wheels after &lt;1/4 turn of the front wheels. The 1st gen. is somewhere between 1/2-2 revolutions of the fronts before it engages. If you're interested in making a high powered awd crv, you should look into DSM differentials. Supposedly they will fit with minor work and they hold quite a bit more power. Perhaps the Pilot/MDX rear would work as well.

Going to have axles and a driveshaft made by Mark Williams anyways. A local machine shop is going to make gears for the transfer case.

When the 2nd gen engages the rear wheels, do the front wheels keep spinning too? What years are the 2nd gens?

What year DSM diffs. supposedly work?

Dave421

2nd gen. is 2002+. 97-01 is 1st gen. The 2nd gen's system acts just like the 1st gen. except it is quicker to respond to front wheel slip. Once that's detected, it sends something like 40% of the power to the rear wheels. As for the DSM diffs, I don't know. I just remember reading about someone doing it a while back. I think it was 1st gen (not F&F style eclipse) but I really am not sure.

Does anyone know how close in szie the transfer case of the CRV and a 90-94 Eclipse GSX are?
