woah nice work

 

Thanks guys, I'm pretty excited about this conversion. I think it'll be a decent alternative to the v160 setup for those who don't mind having their trans cut and welded. Definitely a much more cost effective solution in not needing a special flywheel/ clutch combo.

 

Did you ditch the mazwerks adapter plate? Just curious as to why you are going this bell housing cut and swap process.

 

Yes, I opted to do it this way because the adapter plate only bolts to the top portion of the block leaving a gap on the bottom and I wanted to have as much of the z trans supported as possible. I'm sure it would have worked fine, but I figured it was going to need machining anyways in order to run the clutch setup I chose. From my research, I saw that all the trans swaps that use adapter plates require a custom thicker flywheel which costs another 700 on top of the twin disc price. By having the housings machined and welded, I can bring the splines closer to the flywheel, allowing me to use an S2000 twin disc set with 350z friction discs.

 

Love it! This is definately an option I will look at closely when I get to the point I need to find another transmission solution. I'm still at my stock transmission, and have one spare. So when/if I break the transmission, I have a spare transmission case I can cut. I also have a twindisc clutch already.

 

Nice set and you thought like I did on the custom flywheel part luckily with my swap the bell comes off the trans on t56 witch helped out a lot
The trans should work great also just a ideal use a solid piece of aluminum to weld to Bell housings together with the whole center cut out of it to fit the clutch and input shaft will just give you a lot more too well to and Help Center the transmission perfectly

Ahh that's interesting never heard that.in the datsun community they mate a z32 trans to a l28 using an adapter plate like this and they machine the section of the z32 bell housing in the exact dimensions and depth as the adapter so mounted up it all mates flush between the trans, block, and plate. Wish I could find a pic and I believe no custom anything is used just a l28 flywheel and pressure plate with a z32 clutch disk no other mods other than a custom driveshaft and trans to body mount. So I just assumed it would be done like that but that was just assuming.

Yea, my original plan was to use the adapter plate and machine the bell housing mating surface to account for the adapter thickness. However, the machine shop I get my stuff done at only goes up a certain height and the adapter plate only supports the upper half of the transmission so I felt it was more practical to have the housings cut and welded. I would imagine it is still possible to do it that way.

 

If I'm not mistaken the 350z diffs all used a Viscous LSD which sucks and would need an upgrade, the auto's had a different size ring gear as well so the aftermarket 3.9 and 4.08 gears wont fit in the auto rear end.

 

I was skeptical about trying the viscous differential as well, but enough people have used and like the r200 diff for me to want to try it. If it turns out to be a bad diff, then at least it wasn't too expensive, but if it turns out to be a decent diff with the longer ratio, it would be an awesome alternative. I'll have to see how it holds up once I'm done with my build and start putting it through the paces.
