There is a height difference between the JDM and Z32 pivot ball. The washer under the Z32 ball raises it to the level of the JDM. Not that is probably matters much. The way your's is tapped out eliminates the need for the washer.

Here is the Z32 Pivot Ball part number.
30537-40P00 Pivot Ball

Do you mind if I use your photos and integrate it into my PDF file? I never have considered it to be finished.

Yeah thats no problem you can use them.

actually the height of the pivot ball is pretty important. your clutch may not fully engage or disengage if the pivot ball is not the right height. Same with the TOB. would suck to put it all back together and the clutch doesn't engage right.

When i did this to an r34 rb25 pull trans, i bought a jdm cover. it was about $30, just took a while to come in.

rb25det push type front cover: 32110-05U11.. about $30, comes with an OEM pivot ball installed too. up to you if you want to change to a nismo pivot ball.

Hey i want "Complicated? Nah its Simple" under my name.

Yeah i guess it is a small world. what is his name, Hermann's population is only like 2500 people.

I did this conversion because the push type clutch i have found is easier to find and is much cheaper IMHO.

i have an r34 rb25det tranny, not sure if its neo or not. it is definitely pull type. i am doing a conversion to push type so i can use my push type clutch. in order to do this, the most important part is the front cover assembly. it is about $35, and is a JDM only part. it comes w/ a new pivot ball already screwed in. the remaining parts, c-clip, pivot fork, TO bearing, spring, etc. can be found as USDM (mostly matched against the Z). the entire conversion should cost about $100-150. you also need to drill and tap the bell housing to flip the slave cylinder around. however, the casting for the holes is already there so you know exactly where to put it. ONCE you do all of this, you should be able to use any of the readily available push type clutches (namely z32 n/a)

He says its a JDM part?? But from the write up (this thread) it seems like he just takes the Z32 front cover, moves the pivot ball to the other hole, bolts er up and calls it a day am i not correct?

The process would be identical for the neo bellhousing correct?

Ah awsome man thanks for clearing that up. where did you source this jdm cover from? do you have a part number?
