Initial matchup of parts for B-series awd.

Well as of last night I pulled out the rear diff to try and match up and see what was going to be needed for install of the CRV diff. Defianly not going to be any kind of bolt up affair. However the bracketry is not going to be too awfully hard to make. Hopefully I can be stratigic and mabie place the rear diff in a better place so there isnt as much angle to the axles as I plan on having this car stuffed.
I also received my mounts from Hasport and the hydrolic tranny setup for the 88-91 Civics is going to work, along with the cable to hydro converter, but neither is a direct bolt on. The driver mount and the rear mount look to be no problem, however the tranny mount is going to have to be modified. Not sure if the plate that the actual mount bolts to is going to be modified or replaced.
Another note. The spline counts for the inner axles are different. The spline size is actually bigger on the wagon over the smaller CRV. I have CRV axles on the way to do some comparing with as I know the outter counts are the same. What would be cool is if the axles are short enough to just use the CRV axles, but I have a feeling they will be too long.
Ill keep you guys posted on progress as I plan on removing the stock motor this weekend and hopefully putting the b-series tranny and motor together and set in place just to make sure the other mounts are going to work. Im going to go buy a new camera and start taking pictures to post so you guys can see the differences too.

:shock: :shock:
Update: I have the motor out of the car and test fit the CRV/B18C. Bashed in the usual spot for B-series and looks like the rear mount and driver mount is a go. However the passenger tranny mount is going to be interesting to say the least. I might end up moving the mount brackets on the car, but tis still early in the swap. My back was bothering me and Im out of pain pills. So unless someone wants to send me pain meds, progress will stop for a few days. Also taking the little lady somwhere for Love day. So Ill update when I get back from vacation.
Well as of last night Ive about got the passenger tranny mount ready to remount. Yes, Im having to relocate the entire mount. Im also having to modify the chassis quite a bit. Im hoping to weld on the mount tonight providing no one steals my Vicodens
So as of now I tell ya, this isnt the easiest swap Ive done by any means. Im sure a second one will go a lot faster, but as many times as Ive put that motor/tranny combo in and out of the car, I coulda done ten other swaps. But dont worry, Im taking lots of pix and I will do a writeup for the diehards that are interested in doing this swap. Ill update as soon as the motor is bolted in for keeps
PS, man, one thing that would save me a lot of money is finding out the final drive for the awd wagon. If anyone has this info, please, please, please post it up!!! TIA.........
1st: 3.384
2nd: 1.950
3rd: 1.275
4th: 0.941
5th: 0.783
Front Final Drive: 4.428
Rear Final Drive: 2.529
Retreat (?): 3.000
Information is for my Shuttle RTi, unsure how this info differs from USDM Wagon RT4WD.. :?
Thats what I was thinking. I know serious 4x4's have different ratios front to rear, but not by that much. Somethings not computing to me :?:
because there is a Final Driven gear for FWD, and ther is also an additional 'transfer (final) driven gear that is common to the front differential. the transfer driven gear drives another transfer driven gear (yes that sounds stupid) / common shaft which then changes output direction with 2 bevel gears for the rear facing prop shaft.
multiply those 4 or so gear ratios including the rear diff ratio and you should get the same overall FWD final driven ratio.
phew.... i'm messed up and that was tough wording. a cross sectional drawing of the transmission layout makes this obvious.
At first glance, Pacifier's post looks right but its 5am and I ain't looking it up to verify. I do know for sure the 4wd usdm wagons had a 4.4x final drive.
I have a 4wd tranny that's suitable for parts, if you need it...I'd be willing to donate it to the effort buy you'd still have to pay shipping on that heavy sum'bitch.
I wont say that I understand what you said, even after reading it a few times, but my knowledge of trannies is very limited too. Ill run this by the guys I work with and see if he comprehends. Thank you for explaining for the tranny impared
Ill also see if I can get a breakdown so I can try to understand.
sooner or later i'll get around to disassembling one of my 4x4 box's. I'll be sure to post up some illustrations. If you have a 4x4 service manual, there is a exploded diagram and a cross section with leaders/callouts for each component.
