Re: Changing gearing in 97-01 awd crv
Berz - The CRV transmission is basically a H-series transmission with a B-series splined input shaft and bell housing. Not to mention the transfer case (obviously 
). If you need rebuild kits you need the Euro R spec stuff (well now they list CRV kits, but it's just the ER / ATR stuff).
You can in fact put a B-series 5th gear in the SBXM transmission. I have done it personally, and intend to make a write-up one of these years when I get time to do so.

That 5th is also in the F23A1 trans that's in the 98-02 accords. It might even fit w/o modification.

Major ups to lhondist 
I struggled for quite awhile trying to work out a solution that I was happy with to get the F/H series internals fitted into the CRV case. My plan was to machine the crv countershaft to keep the CRV fd but be able to run all 97+ Prelude gears and a custom machined Quaife/OBX style diff in the CRV configuration. I think that would have been the ultimate as far as keeping a more favorable fd with regards to acceleration. But it's equally awesome just to see someone actually went ahead and got it all done and together and working
To the OP- I would say trans wise, you don't have a whole lot of options. You can do what lhondist has done which will give you tighter gearing 1-5, but with an even taller fd which will only make your situation worse. You can do what I was planning which will give you tighter gearing 1-5, but with the same fd you have now. Either way not alot of improvement. Other than trying to get a custom FD machined, you're pretty much sol unless there is some other model vehicle out there running a similar trans with some rare oddball shorter FD that none of us are aware of.
I would say your biggest problem is your choice of engine. CRVs are not exactly beasts to begin with, and you swapped in an engine with even less tq than what the stock engine had. If I were you I would go with a fairly stout built B20vtec, or a supercharged LSvtec. The good news is you can find used jrsc kits for pretty cheap these days. You can also check with MercRacing, he kind of specializes in making bigger and more modern blowers fit above and beyond the standard kits. He deals with mostly k stuff but he might have some b stuff available too

Re: Changing gearing in 97-01 awd crv
It's been awhile since I had my hands on any of that stuff. After I found out how much simpler it was going to be going k series I ditched all my b series awd gear. But iirc, the crv countershaft and ring gear are crv specific, as is the 1st gear. As in not just different ratios, like completely different design. I hadn't found any other Honda parts that would directly swap without requiring machining. The crv countershaft is more or less an F/H series design but with a different 1st gear bearing journal and bearing (can't remember if smaller or larger). In theory the easiest/best way would be to swap in all F/H series internals but then you run into issues with ring gear/transfer gear offsets. This is why I ultimately pulled the plug on the project. It was to the point where no matter what I tried, it just caused more issues elsewhere that then needed to be resolved. Like I just kept painting myself into a different corner. And considering the end result wasn't going to be all that awesome comparatively than if I just went K-series, that was the route I ended up going. Hopefully some other brave souls stuck it out and can chime in here

CRV ratios
1: 3.500
2: 1.956
3: 1.344
4: 1.071
5: 0.812
FD: 4.562
R: 3.000 (97-98 models), 3.461 (99-01 models)
Integra LS ratios:
1st: 3.230
2nd: 1.90
3rd: 1.269
4th: 0.966
5th: 0.714
Reverse: 3.000
Final Drive: 4.266:1
Integra type-r ratios:
1st: 3.230
2nd: 2.105
3rd: 1.458
4th: 1.107
5th: 0.848
Reverse: 3.000
Final Drive: 4.400
The CRV ratios look very similar to the LS transmission, i want the tighter gearing of the type-r / b16 transmssions. The 1-2 shift is horrible and the rpms. I realize that the CRV's have a good final drive ratio, but I am just wondering if i can use 1-2-3 out of a tighter geared transmission

It's H22A4 transmission with a higher ratio 1st gear, and the 92-96 Prelude VTEC 4th gear. (And of course the different final drive).

[QUOTE=Bense;52095824]I don't quite understand the point of this kit.
So you can put all the gears from the GSR, B16, ITR, LS, or a combination of any of these into the SBXM.

Re: Changing gearing in 97-01 awd crv
I've seen that thread, which is still incomplete BTW. So I don't understand what you are not understanding about the point of that kit. I'm not trying to sell products for Speedfactory, I'm merely providing info on something that pertains to this thread that could potentially make people's lives a little easier when building the SBXM. Unless you own a machine shop or have access to all the equipment of a machine shop, this kit is a much more time and cost effective solution for changing ratios in the SBXM. Isn't that the point?

Re: Changing gearing in 97-01 awd crv
hi man
haven't logged in here in years .....
the bearing still holds perfect
i figured that the outer of the bearing is safer to machine as the shaft has treated surface that rolls on the rollers so more likely to get damage after machining
