just what the title says, got an 88 jdm zc trans going into my 90 hatch with a y7/z6 motor combo. do i use the 86-89 teg axles and intermediate shaft or the 90-93 teg axles with that intermediate shaft? ive searched. please let me know.


Brett

 

ZC intermediate shaft (Integra intermediate shafts won't work) and 90-93 Integra axles - if your hatch is STD model, you will need to swap knuckles/hubs for ones from a DX or Si

 

Clutch disc is gonna be different with it being a 88 model tranny also

 

its the Int. shaft and 90-93 Teg axle combo.

But the Int. shaft will not bolt to your block.

 

so there is no US axle and intermediate shaft combo that will work? my si trans is about to explode, i need to know now.

and why wont it bolt to my block? i thought single cam blocks had the holes for intermediate shafts?

i already have the correct clutch disk i need. and there is NO way i can use the factory single cam axles?

IS THERE ANY WAY I CAN MAKE THIS WORK?

3 options:

1. Stock sohc axles with 90-93 inner joints...no ishaft

2. 90-93 integra axles w/ ZC Ishaft but the outer dust rings will have to be removed before installation into the hub

3. 2 Right Side Crx Axles w/ 90-93 integra inner joints w/ ZC ishaft

this is assuming that you have dx/si hubs

option 2 and 3 require the use of ZC ishaft and ZC ONLY

the easiest option is just to get your stock axles moddifed with 90-93 Inners if your in a quick fix

with the Ishaft however you will have equal length axles and significantly reduce wheel hop and tq steer

 

the whole inner joint? or just the cup? im sure i can grab a set of broken axles just to grab the cups. let me know asap, that would be great to just be able to use the sohc axles.


Brett

 

you should be able to use your stock SOHC axels.

 

^^^ what he said wont work, All ZC tranny use a larger spline for the Int. shaft, and a Y7 block does not have holes for the Shaft either.

Your only other option is to pull your Si trans apart and use the Diff in the ZC tranny not the ring gear (unless you want to do hella more work in the tranny) but the diff, It would be very easy to do and allow you to use your Stock axles.

 

how do you figure? i have 4 friends with ZC swaps with the ZC tranny that have used their stock axels.

 

Might want to check on that...unless they switched the diff, they're not using "stock" axles. As you can see, theres a number of bastardized ways to use usdm axles but not stock.

And the d16a6 block did have threaded taps for an intermediate shaft. I've read conflicting things about later d16s and any of the d15s.

Let this be a lesson to anyone buying a zc tranny...get the ZC intermediate shaft.

 

you better tell your friends then they got jipped on there tranny if they *supposedly* have a real ZC tranny but were able to use Stock 88-91 EF axles...

 

JUST THE CUPS sorry not the whole inner joint


but for all those guys above with "zc tranny" with "stock axles" got jipped!

H-T home of the my friend, he said, she said, my momma told, blah blah bullshit

 

honda looked up the tranny code in their system and it came back as the ZC....

 

I know for a fact in my own personal dealings with ZC's for the past few years, the TRUE ZC trannys, ALL OF THEM, have to have a Halfshaft. whether they are SOHC ZC trannys or DOHC zc trannys.

And you cant just stick the inner hub from a 90-93 Teg into the drivers side of Diff either it will not lock in, because the HALFshaft doesnt take clips for the splines on that side.

 

it may not take the clip, but it will work and not pop out

and i have personally used this set up before until i had found a ZC ishaft

okay i will give you that, I know they will slide in, but I didnt want to take the chance of a axle popping out on me. So I swapped a Si diff into my ZC tranny to run stock axles and i got a hybrid tranny too!

 

yea i want an SI final drive too, but i just love the ishaft (no tq steer) combo

but i saw someone posted that SRR is making 4.7 and 4.9 for ZC tranny

 

will the tranny leak if i just stick the integra inner joint in it? or will it make a good seal? i know im not going to be able to find a zc intermediate shaft before my si tranny ***** the bed, so im just gonna disect my stock si axles and do that.

oh, and i know someone already meantioned it, i dont have to swap my hubs to dx/si, i already did that when i had the b16 in my car.


Brett

 

no they will not leak, unless your axles input seals are bad, you can get new ones from honda for 6-10bucks each and the ones at honda are actually 90-93 Integra input shaft seals

 

um, well i did as you said and it works great!!! shifts awesome and everything, to bad ive had the axle pop out on my TWICE now. now i run into a huge problem, i have this wonderful tranny in my car with these great gears and smooth shifts, but im always worried about my one axles popping out.

vtec4thechildren, i would not have put this trans in if you hadnt said "they will not pop out". well, now im kinda fucked, i have 200 whp, but im worried about shifting hard in fear of dropping an axle.

how low was your car? how long did u have the inner cups in for? is there any way i can tap holes in the back of my block to make the i-shaft work? please help me.

OR, does anyone have a writeup on installing the si diff in the ZC case? i need it bad.


Brett

 

Ah it has come back..

Yes now I have heard of people being able to tap the block for the bolt on the INT. shaft., There are spots on the back of the block (maybe older blocks)....I believe in your case maybe.....you will just have to look for three solid spots sticking away from the block a little bit, they will be right up under the Oil filter.

Now you will probably not find any write-ups on the Si Diff swap, If you want to make it easy on you and just have the Si Diff with all the same ZC gearing just take out the diff, and put the ZC ring gear onto it and put it back in.

Doing this will allow you to have the exact same ZC gearing but able to put in stock axles.

If youve never pulled apart your tranny before I suggest you just go the above route as opposed to making it a Si/ZC hybrid like mine, theres ALOT more work involved and its not exactly easy for beginners.

 

hell, you dont necesarily need a Si diff to just be able to put in stock axles, just get a Differential minus the ring gear on it from ANY (88-91) d series 5 speed.

Just remeber FD ratios do not come from the differential they come from the ring gear and input shaft spline count.

 

oh yeah i know about the ring gear, im no noob. ive pulled apart a tranny before, and i actually have an almost bare one in my basment with the diff still in it. i think thats what ill be doing if i cant find the zc shaft.


Brett

 

well since your not a beginner to this....Take the input shaft outa the Si and take all the gears off of it....Then do the same to the ZC Input shaft and put all the ZC gears onto the Si input shaft and just use the Si 5th gear on both the input shaft and main shaft, put the SI Diff + the Si Ring gear in and your set to go with your Si/ZC hybrid tranny.

I got mine done in 4 1/2 hours so its a little time consuming and be patient with it.

OH and remeber not to torque the end nuts on the Input and main shaft no more than 80ft/lbs or it will whine like crazy. Might tear something up too, I didnt give mine a chance too tear p before i fixed this.
