EF8 CRX SiR Driveshafts - do any other models' driveshafts fit?

[crx51]

Hi all
I've searched the compatability but can't seem to find anything that lays it out simply. My understanding is ef8 and ef9 are compatible?
How bout EG/Delsol?
Any others?
Or does anyone know where to buy new driveshafts for an EF8?

Thanks mate, I have been talking to him about his old driveshafts.

ED CRX wont fit (USDM EF is same as AUDM ED). I think a buddy of mine ran ED driveshafts and they were too short and the joints would almost pop out at full lock.

EF8/EF9 are basically the same car in terms of engine bay. So the shafts and midshaft are the same.


If you have shafts already and the CV joints are ****ed, I am sure you can used other joints like ED joints. I believe I used a ED inner joint on my EF8s shaft back in the day.


Generally what we found was the EF8/9 is kinda a mix of parts between the DA teg and the ED crx/civic - don't know how much this applies to the shafts though.

That's excellent information thanks mate! Can anyone confirm which cv inners are compatible for use in the EF8 driveshafts?

I don't see the fuss.


Just take ef8 shafts into drive shaft shop and 30 mins later. Walk out with virtually new shafts

read that thread..
From memory I used a ED crx inner joint. It worked fine for years. Technically it is a different joint, the EF8 has rollers in the inner joint where as ED does not - but still works fine. (this is all from memory of 8 years back).

Inner joints are easy to swap (but messy to fix) - outter joint can be easy.. but I recently had an issue with an accord shaft that didnt want the outer joint to pop off.

How you doing mate... I am the buddy Dxs speaks of. I've had my fair share of headaches with the EF8 driveshafts. I've tried a few combinations and what I can say is:
- Early DA axles are too short and will pop out (ask me how I know)
- Late model DA axles and DC axles are too long and will bind (car will vibrate at speeds over 10km)
If you can't rebuild your current shafts, what I can recommend is to build a hybrid/custom driveshaft, which is what I did and worked well.
Using your EF8 midshaft, you will need to get the outer joint and axle from an early model DA integra (87-89) and use a later model DA integra (90-91) inner joint (or even EF8 inner joint). Put it together and you have an EF8 sized driveshaft.
Reasons for this I found are:
- Later model DA shafts are longer than early models, which may cause binding issues.
- Early model DA inner joints are a few cm shorter than later DA models, and may cause the shaft to pop out of the joint.
- Having the longer inner joint mixed with the shorter shaft gives the right length compatible with the EF8/9

It's been a few years since I messed around with my axles so hopefully this information is somewhat accurate and useful.
