Who are you using for plating?

TFC in Oregon, they do Z theraphy's stuff, and I was impressed, so I switched, this is the 3rd zinc shop I have used, they are my favorite. But prep is key.  This batch is a little more blue/ purple then I would like.

Good to know. So your hardware is prepped and clean when you send it? I went to a shop an hour away from me in Asheville and the two guys I needed to speak too weren't there. I emailed one of them and he didn't respond. So I am operating on the premise that they are not interested in helping me. I would prefer to send money to people who are interested in helping me...Anyone in particular to talk too?

I would use local, try and stop by the shop.  I bet you can figure it out.  

 

If zinc is intact and oxidized or whatever, then i don't do anything.  Rust has to be removed, paint has to be removed, some places can acid bath before, so not much prep is needed at all.

Osgiken single disk clutch is in from japan. 

I took a stab in the dark with it. Zgarage had me be a guinea pig. Flywheel and overall weight is pretty great! Very very well made. Comes with everything needed.

Not really any place local and most commercial platers don't want to mess with it. If I'm going to have to ship it, then it doesn't really matter how far I ship.

I had a good conversation with Luis @ TFC a minute ago

Nice. TFC has been great. 

 

I am making my starter pretty (vapor) Plus my r180 cover. 

 

Starter will get a nos solenoid, then some zinc and some black paint. I can’t get the side screws out so they will get painted. Should look nice.

Hopefully shimming the r180 and getting it installed this weekend. Looks pretty amazing. I ended up getting new side bearing holders. They were 18$ from Subaru with seals. Which seemed too cheap not to replace.

I screwed something up in the trans rebuild, it becomes tight with the front cover on, plus I guess I love spending money, so I decided on the KA swap for my 240z.  This is a longer tail shaft on the trans, so it should fit in my series 1 better (no cutting), plus the 1st is better gear ratio and 2nd is slightly better.  I found a 1989 240sx trans, with 576 miles on it.  It's been in storage inside since 12/01/89!  Zinc is still in tact.  Paid too much for it, but hopefully it's good.  The shop tested all the gears and syncros.  

 

Troy Emerish Racing will do the bell housing mod.  He is just about as cheap as my local machine shop, plus has done a ton of them.

I wanted to send it back, since it was so blue/ purple, I decided to just live with it.  

Did you contact them at all?

Well shimming the r-180, backlash, pre load and wipe pattern took most of a couple days after work and most of a Saturday morning. I think I took it apart 20+ times. Finally happy with the wipe pattern. Luckily I didn’t have to change the pinion shim.  Edit: I think in a perfect world I would have had a special tool to set the pinion nut at the factory 125-150ftlb. Then used different shims to get the bearing pre load perfect.  But I had no way, so a couple of hits with the impact is what I used to set pre load, I found that info on here and a few youtube videos.  It's not precise at all, just hopeful the factory had it correct enough.  A bunch of site posts and a few guru told me to just reuse the pinion shim and move on.  Everyone basically told me backlash is the most important.  

Ended up with 5 thousandths for backlash give or take and then ring side backlash shim if .05 and other side of .07.  Total inch pounds is around 8-10 on the pinion. No carrier I had around 3 inch pounds for the pinion. 

This is worth paying someone to do. Just FYI. I had fun. But super frustrating.

Finally got the ka trans. This is a low mileage (500) miles trans. Been sitting on the shelf since 1989.  I found it on some parts website. Vapor and some zinc and it’s looking amazing. 

 

Bell housing mods are being done Emerish racing.

Ka is in. But I cut down a driveshaft had it balanced and powdercoated. I just used some measurements from posts but they are super off from my z. 

 

I really want a 4 post lift. Working under a car on jack stands sucks

Where did you buy this awesome transmission crossmember? BTW I used a Series 1 driveshaft which is slightly shorter. It fit without shortening (tight fit, around 5mm travel left).

I love my 4 post lift.  Best thing I ever purchased for the garage.  I’m lucky I have tall ceilings.
