I'm building a z6 because I bought my hatch with a b16 swap. Although it was fun while it lasted I never planned on keeping the b16 in it due to emissions testing crap. Had the head been a year newer I might have been able to bar it and just leave it alone but as things work out it's a 91 head in a 93 chassis.

So on to the disassembly. Removing the flywheel and crank pulley with only a breaker bar.

Locking the flywheel in place to remove the crank pulley bolt.

Done and timing cover removed. Will need a new one.

Gone

Opening it up

Girdle removed, you can still see the oem paint on the bearings.

Close up of the main bearings

Rod bearings in order and thrust washers

Close up of number 1, slight discoloration on the rod cap. Unfortunately no macro setting.

Everything will be off to the machine shop tomorrow for cleaning and clearance checking I can't do myself.

Oem rod bearings for this crank are yellow, green, yellow, green. I'll have the crank micro polished and see where I end up with clearances and probably go with oem bearings. Hoping the cylinder bores are in good shape.

 

[BiGrEd1011]

nice dude good luck with the build! Are you doing a turbo build or just a swap for now?

 

[NeonPinHead]

I live in california and have zero emissions equipment on my b18b1 high compression build. Whats the big deal?

 

[Sidneyious]

Ingenious idea on removing the crank pulley, never thought of that

 

[buzzbomb]

nice, what are your plans? stock rebuild? boost?

 

[robgoof]

yeah ,hot strip D-own...

whats yer plans ...

 

[jeremy85]

Hell yea

So today there should have been pictures of the z6 ready from the machine shop but I hung around until the crank was finished Friday to find out the damage to the rod journal was greater than I noticed before I took it in. I spent the weekend working late nights I didn't get around to checking the junkyard for an automatic z6. Sure enough I found the only one nearly intact and sure enough I had forgotten all my 12 point 1/2" sockets. Spent a couple hours tearing the whole drive train out because I didn't have any way to remove the axle nuts or separate the ball joints. So after a bunch of ridiculousness I had gotten the passenger axle removed from the transmission using only 3/8th" sockets, a ratchet, needle nose pliers, regular size flat head screw driver and a drive shaft. Dragged it out, pulled off the transmission and left it there for tomorrow since I couldn't remove the flexplate. Guess that means I have to wake up super early before someone else picks it up.

So did you get it? Was the VC on the motor, or did you remove it?

 

[Chrisfrom1986]

The valve cover had been previously removed, when I got there this morning I took one off the d15b swapped automatic next to it and started stripping the bottom end of the z6. Right away I knew there was a problem as yesterday when I checked the crank pulley it was loose. Since I had my 1/2" sockets with me today I began by removing the pulley bolt. It came out with much difficulty and I found it to have stripped the forward half of the crank threads. Since it was the only z6 in the yard I just said fuck it and called the machine shop and told the owner Andy to just go ahead and cut the rod journals .010 under and recondition the rods. Picked up a couple things before I left and that's about it. Guess I'll order the rings, rod bearings and gaskets.

As far as the transmission goes I had a few minutes at home and decided to open the 2 B000 cases I had laying around. Found one to have a broken shift fork and the other a trashed isb at the least. At least bearings for d transmissions are cheaper than b.

Here's what I brought home from the junkyard instead of a z6 block. Cost half what the longblock would have anyway

 

[Chrisfrom1986]

Everything's back from the machine shop. Still need to decide what I'm doing about the crank. Haven't been able to get a good picture of the rod journal with my shitty tablet cam. I think the only thing I'm missing is rod bearings before I can put it together. Also need to get rid of that mark in the combustion chamber.

 

[BeerDrinkin]

Do work son.

 

[Chrisfrom1986]

So this took a back seat to work the past couple months and it's time to get back at it. Had to stop by HF to pick up some hex key sockets. Popped the interlock guide bolt right out with the new 1/2" craftsman impact driver I picked up. Don't feel like taking apart the fork assembly so I'm just going to drop one in from another trans that needs an input shaft bearing. Of course a total cleaning is in order as well.

 

[transzex]

nice half 1-2 fork you have...

 

[Whoshot]

...shit, took me a second to see that....

 

[transzex]

I have broken a 1-2 shifter fork pulling into the driveway...

 

[Chrisfrom1986]

Well the transmission carnage continues and it looks like a 3rd donor will need to be obtained from somewhere, maybe an s40 dx for the forks I'll need.

This trans came free from SOCHitTOem, he was very generous and met me in Daly City to drop the transmission off almost a year ago. This one will be put back on the shelf for later as I was planning on using the 1/2 fork from this in the other trans. Just goes to show how things never go as planned.

 

[BLK92_D16]

^Wow! That trans looks mighty good. LOL!

 

[robgoof]

dang another tranny surprise..

keep it up!
