B18C5-EH2

Well I think I might just be dropping in a DOHC ZC swap into my 1990 hatch (yes I could have posted this in the EF forum, but I need some of the EG D-Series guys help here too with this) and I'm creating a closer-geared tranny by using the ZC 1-5 gears in an Si case with the Si better final drive assy.

Here's my questions pertaining to the guys who hang out in the EG forum and are SOHC-savvy:

Will the LSD unit from the hydro D-Series VT-i fit into the cable D-Series tranny?

Also I know eg6ajk found out the hard way that the SRR 4.929FD won't work with the LSD from the VTi, so here's my next question:

If the LSD from the VTi won't bolt into the cable D tranny, would the SRR 4.929FD work in a cable D tranny?

Thanks in advance.

Very good question. I think Mista Bone has a write up on swapable parts for d series tranny's on the d series message board. Worth a shot to check it out.

dont think this is gonna work for you. wasnt the problem with the SRR final drive that the bolt pattern was different? The final drive bolts to the Differential, so the two must not be compatable. But I think you are trying something different... using a hydro-tranny LSD in a cable-tranny might let you use the SRR final drive for hydro-trannies inside a cable-tranny. So, does a hydro tranny lsd fit in the cable tranny case?

Let me clarify:

The SRR 4.929Fd will NOT work with the VTi LSD diff.

So I was asking if one or the other will work, because I know from eg6ajk's testimony that the SRR FD and the VTi diff won't bolt together.

I'd take one or the other.

I would think it would work. I have heard of guys using an Si(D16A6) final drive in a Z6(YS1) tranny with ZC 3rd gears....

If the Si final drive can work in the hydro tranny, I would assume that the hydro final drive would work in the cable!?

This is only if what I first said was true. Then again, it was hearsay, not first hand.

Hey Emerica, the YS1 tranny is a cable B-Series tranny found in the 1990-1993 Integra.



The S20 is the hydro D Sereis tranny.

as far LSD from hydro to cable its a yes and a no. if its OEM honda VTi LSD then its definatly not going to work (due to fact that it requires ring gear and counter shaft to be used). if its a aftermarket LSD such as KAAZ or Quaife then yes it most likely will work (I say most likely as there were two bearing sizes 35 & 40mm)

again the SRR FD will not work on the cable becuase the need to use the counter shaft with it. since the sizes/designs of the cable and hydro trannies is much different again its no go.

so what can you do? for one you can get a ZC LSD unit or even better find:
92-3 SS0 tranny from a ZXi integra (cable) SOHC ZC which came with optional LSD as well as 4.43 FD (gearing was on par with d16a6, but ZC can be swapped). it uses a half-shaft setup. (where can you get one? I do get them once in a while)

also for those with KAAZ or Quaife (35=-40mm deal):
