Re: AWD CRX del Sol - CRV driveline swap
And Im starting to get really interested in a solution for the back axles... I saw one of matts videos against an Evo and a 7k launch with 200ish hp snapped what seemed like the cv joint, and 10sec later shattered the whole shaft... not good for the 500ish hps im planning... jaker and I think lostsol is his name are using porcshe stub axles with crv bearings.... but what the hell would you bolt them to that would maintain the correct final drive in the diff... so confusing... can anyone get measurments on ring gear bolt spacing, diff size, and axle info on the CRV and Wagon diffs? Ill try and see if the S2000 diff is an option... there has to be something strong enough in hondas bin to put together....

Re: AWD CRX del Sol - CRV driveline swap
I'm definitely getting closer to having a working lsd for the crv rear, unfortunately it's going to end up being a custom unit tho as I've been unable to find anything close enough to be modifiable to work. It's been awhile since I've seen an s2k diff in person but unless my memory is making stuff up again it's not even close- its closer to a standard d/b/etc-series unit. It would require so much reworking that you might as well start from scratch with a custom housing

Re: AWD CRX del Sol - CRV driveline swap
actually the lsd I'm working on could theoretically be built in 2 different versions, one for stock crv inners and one for d-series inners. I think anything beyond that will require mods to the crv housing but I'm still working on it
As far as axles go pretty much any way you slice it you're looking at hybrid axles unless you run a crv style diff (23 spline) with the crv hubs. Personally I'm shooting for d-series axles. I should be able to get the diff to accept the inners, and they go into the teg hubs. All I'll have to do then is shorten 2 driver side d-series axles.

Re: AWD CRX del Sol - CRV driveline swap
maybe a stupid idea, but if you're going to modify the driveshafts any way, why not go for the strong nissan R200 diff, just go see a 300zx wrecker.....he'll have one... if you're going to shorten and re-spline axles, you can re-spline anything..
like the driveshaft shop's conversion for the S2k.....

Re: AWD CRX del Sol - CRV driveline swap
ideally i'm trying to stay away from having to respline just for the pita factor. Not to mention I'm going awd not rwd so I'm pretty much stuck with the crv rear. If I do end up running the teg hubs they will accept either d- or b-series outer joints, and as I mentioned the diff I'm working on hopefully will be able to accept stock d-series inner joints. So the only thing that need to be done with the axles is to shorten the center length which is pretty painless
d-series axles definitely wouldn't be the most bulletproof way to go if strictly rwd, but for awd and considering I'll be running lsd in the front as well I'm figuring it should be fine

As for fine, hehe what are you considering 400hp? more?
Also what LSD are you running in the front? phantom grip, or something custom?

Re: AWD CRX del Sol - CRV driveline swap
The custom FD's for the nissan diff are plenty, maybe there is one that matches, I didn't do any research into it, but I wouldn't be surprised if something close would be available..

Re: AWD CRX del Sol - CRV driveline swap
Hey Rallysol, you mind if I post a few pics of the underside of my car. maybe you can help me figure out how to keep some of the parts Ive put on it? Also I was talking to my friend and he had mentioned that he heard some of the CRV boys fitting S2000 diffs into the CRV housing... could be hearsay though.
Jaker, as for the Rayne people, I e mailed them about the rear trailing arms they had to complement your fronts. I asked whether they'd assemble them with the wagon rear hubs. They said they havnt done honda stuff in a while and they'll kick back production in March, but they didnt shoot down my idea, and that would be one part that would get my project one step closer to "bolt on" (atleast the part I worry about the most, it driving straight)
Anyways, thanks guys, and happy new year.

Re: AWD CRX del Sol - CRV driveline swap
lol wtf I thought you already did the vtec swap way back when
we've got a B20vtec in my gf's ek hatch and boy does it make a huge difference
that car's a blast to drive, I steal it every chance I get

Re: AWD CRX del Sol - CRV driveline swap
When my pocketbook says I can
Naw dude. Doin' a crvtec has been mentioned a few times in the thread, but I've been rockin' a bone stock B20 since the beginning. Talkin' with friends about it and they're tellin' me the same thing, its going to make a huge difference. Debating if I want to toss it on or wait til the other bottom end is finished... tossing it on is winning. Whats your gf running for maps?

Congrats man! I tell ya, Vtec is like going from an electric weed wacker to a full out chain saw! gotta love it!

Re: AWD CRX del Sol - CRV driveline swap
The head is gonna sit for a while while I focus on getting the civic wagon diff and coupler in the car. The group I auto-x with is throwing a trial drift event the Saturday before their auto-x event in March. I'm feeling pretty motivated to pull the driver's front axle and run the drift event rwd. Would be a good experiment to see where it'll break if it breaks at all at this power level. Good thing the car is a trailer queen. =P

Re: AWD CRX del Sol - CRV driveline swap
If you're leaving the viscous coupler in there with the Wagovan rear diff, I'd be afraid that you'll fry the coupler running it as RWD only. Also, by leaving out the driver's front axle, you'll be spinning the spider gears in the front diff pretty hard a lot of the time, and we all know what happens with the open diff drag guys - diff goes kaboom and takes out the tranny case.

Re: AWD CRX del Sol - CRV driveline swap
but isn't that how the braile guys did their drift demos? take out the front axles and let the rear viscous coupler do all the grunt work?

Re: AWD CRX del Sol - CRV driveline swap
I would think that would be a completely different scenario vs just having them free spin. You see those kinds of breakages in drag racing because of shock loads on the parts (ie, clutch drops and whatnot)

Re: AWD CRX del Sol - CRV driveline swap
I spoke to one of the guys on the Braile Drift team a few weeks ago, and he told me that the viscous portion of the rear end was disabled (welded).

Re: AWD CRX del Sol - CRV driveline swap
Yeah, i would think that when you're running any sort of rwd setup with this application you would disable or remove the coupling because there would be no reason to have it in there (no torque to transfer front->rear)

Re: AWD CRX del Sol - CRV driveline swap
^^^ but you remove the viscous coupler entirely, you'd have to replace the whole rear differential, i'm pretty sure. which means a different driveshaft, and possibly different mounting points for the rear differential, and different axles...

Re: AWD CRX del Sol - CRV driveline swap
But that's exactly what Rallysol is doing. He's going from the CRV rear diff to the Wagovan rear diff. The Wagovan has no fancy crap in the diff housing. Just a straight ring and pinion with a regular differential.
