I'm posting this in ALL 3 threads regarding the Z32 transmission swap

 

We can still use the FACTORY speedometer with the Z32/RB25 5-speed transmission swap!!

 

Mike Rowe was able to find a mechanical speedometer pinion assembly (Nissan part number 32702-02G17) that came from a Nissan Hardbody (D21) truck... with the manufacture years (1986.5-1994)

 

This replaces the electric speedometer output.. and converts it to a mechanical speedometer output!!

 

Incredibly.. the speedometer cable bolts right up to the new pinion assembly and it works!!

I think it cost me around $46 from Nissan =)

HOLY MOLY! You just saved me $300 for the electric to mechanical converter. I am placing my order for that part now! How close does the speedo read with which pinion/rear/tires?

 

http://www.courtesyparts.com/ sells it for $28.00

 

It looks like the pinions cost about $12.00 each and are available in 17,18,19,20,21, and 22 teeth

 

 

Thanks Mike and ProX!!

:cheers:

Hey Guys,

 

I finally have Z32 shifter relocators for those of you that are still working on swaps. I am having the protptype tested by a member who is working on his swap and once I get the okay from him then I will make the rest of them...should be about 2 weeks and they will be ready to go. They are simple and strong, made from steel, TIG'd and powerdercoated.

Ken didn't you buy my relocator?!

 

what additional work was required?!

 

Yea, everything bolt up fine but it was hitting the pasenger side of the trans tunnel and one of welds on the left side cracked when I bent the bracket during the install. Had the machine shop remove a small section to allow for clearance and added a few support welds in the critical areas.

Aww man!

 

Remember i sent ya a PM saying you will need to do some slight tapping on the actual transmission tunnel to fit the adapter. Either that or cut off the corner of the bracket with an angle grinder or something.

 

I didnt realize the bracket touched the tunnel untill I finally raised the unit in place.

 

Like I mentioned the unit was a quick prototype... but works with a bit of massaging. The machine shop didn't charge you much did they?! I feel bad now

No big deal man, I did not want to hammer the tunnel and he only charged me $20.

 

I have been having a very bad vibration coming from the shifter under acceleration and primarly in first and second, any ideas?

 

I'm running the Garrett style transmission mount with the 7 inch carriage bolts and I installed all new OEM bushings and shifter components as you recommended to fit the Fidanza shifter.

Gents,

 

I have purchased the adaptor from 240hooke, I have machined and install the adapter.

 

My issue is that I can not use the Z32 stock shifter, because I have my L28 in a shorther vechicle, this means that I have to use the shifter that you guys have been mentioning in the forum. The one that goes right on top of the black cover.

 

I have order a shifter from courtesy parts, but the shifter cover plate and the SS shifter guide plate that goes into the tranny does not fit.

 

I am really stuck here, can you help me and advice which shiter should I use, or where I can buy the right shifter to work on the Z32 tranny ?????

OK I'll get right to it.

 

Heres the basic kit. You will still need to get a driveshaft made.

 

This kit is available for sale and can be purchased through Mazworx.com

In order to do this swap you'll have already taken the bellhousing of the Z32 trans off to get it machined to accept the adaptor. But I'm gonna cover putting it back together just in case.

 

Heres what you should have.

I stood mine up like this for reassembly but it could lay flat too.

 

IMG_2043.JPG

 

The first thing you'll need to do is locate this thrust bearing with matching plate.

 

IMG_2044.JPG

 

The bearing goes here on the countershaft, rollers facing up.

 

IMG_2045.JPG

 

And the plate goes here, concave side up.

 

IMG_2046.JPG

 

Make sure your mating surfaces are clean and then silicone up both sides.

 

IMG_2047.JPG

 

Next go ahead and install bolts and zip em tight.

 

IMG_2048.JPG

 

Now turn your attention to the shifter and shifter plate that came in the kit. 4 bolts/nuts and mount it in the same location as the stock shifter. The plate is installed over the shifter linkage.

This spacer setup also needs to be installed with the shifter as pictured.

Now that the shifter is installed, make sure that the tranny is in NEUTRAL. Now turn your attention to this sleeve/ball/spring setup. Guide the sleeve in first, then the ball, then the spring, then the tightening bolt. Tighten all the way down.

Installed

The last thing to do is to clean up the mounting surfaces on the front plate, inside the bell. There is a large C-clip snap ring that goes on the main bearing, and a smaller C-clip that goes on the striking rod that comes through the bell. Sorry didnt get a pic of that. Once those are installed, silicone the surfaces and bolt it up.

 

Now you'll want to setup the fork/throwout setup. You will reuse the L28 throwout bearing and use the Z32 fork. Once that stuff is on you're ready to bolt it up.

 

Now grab the adaptor and bolt it up to the engine using the tapered bolts (for the countersunk holes).

 

IMG_2059.JPG

 

Now before you bolt up the trans, there are two areas that need a little attention with a cut off wheel. the first is the shifter opening. I took off a tad more than needed but the shifter will sit further back than the stock shifter does.

 

IMG_2061.JPG

 

IMG_2062.JPG

 

Now the second area that needs attention (I took pics, but now cant find them :roll:) is the Tranny crossmember ears (1972 and up I think). The case of the z32 trans is a good bit wider and needs a little more clearance. Take the cut off wheel and take a good 1/2" or so off the inside edge. Pay particular attention to the front drivers side ear as this is where the most interferance will happen. This ear must have more material removed, even cutting into the bolt hole and upwards.

 

At this point I tilted the engine back a bit and bolted the tranny up to the adaptor. Then using a jack to support the underside of the tranny.

 

With that said, this is how I chose to do the tranny Xmember. No its not the most glamorous approach but it uses the stock tranny crossmember and I can GUARANTEE that it AINT GOING NOWHERE. If you wanna cut off the ears and relocate them or weld up your own crossmember, be my guest. Hehe

 

The Z32 mount location is further back. Bolt your stock crossmember pieces to the trans and jack up the tranny into the tunnel. I slotted the bolt holes on the mount so that the crossmember comes up exactly rearward of the ears. With the trans all the way up in the tunnel, I then ran two 1/2"x7" Stainless Steel Carriage Bolts through the ears and into the stock crossmember, using lock washers and nuts on either side of both ears. With all the nuts tightened its SOLID. This philosophy is identical to how an engine stand works.

I went ahead and took some pics of shifter location now that the tranny is installed.

Driveshaft specs:

 

Length I gave them was 29 1/16" from flange to output shaft

 

Flange yoke I used (same as zx turbo i believe) Powertrain Industries(spicer) part #3102-20

 

Slip yoke I used (30 spline z32) Powertrain Industries (spicer) part #3103-30

 

Spicer U-joints 1310 series #5-785X

 

Spicer Tube Yokes #2-28-437

 

They had to order a few of these parts in which tagged a few bucks onto the bill but my total was $304.39

 

This Driveshaft is good for 800+ft lbs torque

 

 

 

Hello,

YES! I'm installing one as we speak from a 87-89 Z31 SS turbo car, and I'm making a video of the install. If I can lift it in there tomorrow by my self, then the video will be posted soon.

 

Here is part one of the install
