I know this has come up before but I couldn't find anything on the search. Has anyone ever used HF axles on a ZC swap or should I upgrade to Si axles. This car will not be raced just something to get me around while the hatch is in the shop. Thanks

 

I think the HF axles would be fine, its the gearing im worried about. If you plan on upgrading to Si trans, you're gonna need the trans, axles and matching hub/knuckle assembly. Unless you're running a 4 puck and slicks, you should be okay.

 

they should be fine

 

but I can't use an Si tranny with HF axles?

 

HF axels are smaller so they might not fit into the Si Tranny.

 

nope.

 

Well let me say you don't want anything but a Si or ZC trans on that motor, HF or DX gearing is way wrong. Speaking from experience. 3 days with a DX trans and I was shopping for an Si or ZC.

 

any axle will work is you have the corresponding hub.
si axles for si hub
hf axles for hf hub
dx/std axles for std hub

all axles are the same size at the trabs, just not at the hubs

 

Aren't Si and DX trannys the same except for the final drive?

 

thanks

 

***THE HF AXLES WILL WORK WITH THE SI TRANNY!!!!!!!***
i had HF axles in my ZC/Si set up for a while and had no problems (till the tranny blew up). the tranny side of the axles are the SAME with the DX/Si/HF/STD/LX (whatever). and after 5 months of driving on a HF tranny with a ZC i want to rip that ****** POS out and beat it with a BFH till its the size of dirt (but im not cuz my friend needs the tranny for his girls car). do your self a favor and buy a Si tranny (i got a new Si tranny last week, waiting to put it in). but the axles have been fine with the abuse that i have put them threw, plus im putting a turbo on soon and dont plan on changing to Si/DX axles any time soon...

 

btw yes the gears in the Si and DX are the same but the final drive is different
and the HF and STD axles are the same. and the DX axles are the same as the Si...

 

THe DX trans is geared way to high, gear spreads put you way below the powerband on the next shift, HF is even worse. ZC likes to be between 3,500 - 7,200 RPM . The Plus for the ZC trans, intermediate shaft and no torque steer, lower milage than most if not all wrecking yard Si transmissions. AND you can pick up a ZC trans for as little as $150. Take my word having been through 2 wrecking yard Si gearboxes that where noisey after they went in but appeared good on the garage floor. (they were both worn out, I opened them up). Before I went and bought a ZC trans. And By the way DX and Si hubs are the same, the axels are the same. its HF and STD that had the smaller weaker ones.

 

I have Std axles not Dx or Si there the same thing as the HF axles. They have the small outer cv's. I also have them in my Si trans with my Z6. It will work but have to suffer with using smaller brakes until you get other axles such as Si's or DX's.

 

you got that right, i had one on my zc before and i was in 2nd gear at 90 mph. took forever to accelerate. 0-60 mph in 50 minutes. i did the 1/4 mi in 2 days.

 

Cool so I can just buy an Si tranny and a ZC and will be set. I wanted to keep it as cheap as possible and didn't want to have to search for new brakes and all that crap. Thanks a lot guys

 

Not to beat a dead horse but please correct me if I am wrong:
1. I can use my stock hubs and axles with the SI trany....
2. If i do upgrade to the Si, I could get bigger brakes., but would also need to get different axles from a 89 teg...then I could use the ZC trany..


My car is a 1990 CRX HF if that helps...

i have been told that the STD and the DX/Si have the same brakes, but have the HF hub. damn i better check and make sure, cuz i am going to put the Si/DX brakes on my HF hubs...

 

 

i am pretty sure (i was told be a reliable source on the Resource board) that the Si/DX brakes WILL bolt up to a HF hub. that means you can use Si brakes and HF axles with a Si tranny.

if you use a ZC tranny you WILL NEED TO UPGRADE TO Si HUBS! the ZC uses a hybrid axle and needs part from a Integra and that part goes into the hub (teg and Si have the same size hub)

I dipute that statement. I have a '89 DX hatch, I have a ZC engine and ZC trans in mine, I put unmodified 90-93 NON-ABS TEG axles in mine, they fit and work perfectly. Did not have to mix and match anything. 88-89 axles are too short. And I have the same DX hubs the car had when it was built.

ditto that!

 

but this sutup i.e. (ZC trany and engine in a HF) will not work because the hubs are smaller???? To make it work would require DX OR SI hubs and 90-93 NON-ABS TEG axles...???..

 

Exactly, DX or SI hubs and 90-93 non-abs Integra axels. Hub where the splined shaft goes in is smaller on the HF and STD. Much more prone to snapping them off. Sticky tires and a Si trans you will drive spirited, and you will likely break them then you will still do it. Save yourself time and agrivation, do it right the first time. Do it half assed and you will hate yourself later.
