Seats just came in. Marrad LX2s, they feel great even to my fat ***.

Couple of updates.

Not happy with the FM depowered power steering, so I'm adding in https://kpower.industries/products/e...r-steering-kit Yes, I'm a wuss. I like how it feels, but it's just too much for my wife at low speeds, and considering I agreed with her as part of financing this build that she would be able to track it too, the choice is out of my hands.

Also decided to try to adapt https://www.flyinmiata.com/ND/nd-fm-...ooler-kit.html to a NB. Bottom fitting should be fine, and the fill plug on the 6-speed is just 1/2 npt, so should be pretty easy.

In the middle of building a diff with an OS Giken with 3.3 R&P and a rx-7 rear housing.

Interested on your impressions of the PS kit, I've been eyeing it for when I swap my depowered rack in.

After going through the data on my last track excursion, my tranny is clearly getting way too hot which lit a fire under my butt to do something about it quickly.

Decided to adapt https://www.flyinmiata.com/ND/nd-fm-...ooler-kit.html onto a NB 6-speed as noted in the previous post.

So far, the only things that won't work is the tranny fill plug and the mounting brackets. Since the tranny fill is a 1/2 NPT/BSP fitting, it was trivial to adapt it. Will post further updates/observations on it as things go, but things went going super smooth once the fill plug was sorted out. Initially was planning to mount it in the nose, but I am thinking that won't work. Too many coolers in the nose. Time to figure out a better place to mount it.

Update....

Found out the head guy screwed up with the head. Fresh build, leakdown of ~20% and valve lash was more than double the spec.

Sent it all to @technicalninja to fix. Hopefully he'll be creating a thread on what he does to fix this situation.

@emilio700 Hey, my current builder and @technicalninja have uncovered some massive problems in previous work. Would you be willing to let technicalninja post a thread on how he is going to fix my Supermiata CNC head? technicalninja is worried about any proprietary information related to your head and wanted your permission before he posts a thread on what went wrong, and how it will be fixed.

Crap... i just did this while my shortblock is in the machine shop. Is this just to make sure that you don't bend a valve while turning the cam.

At first I did manage to not realize what was happening when I was turning the cam and the head was lifting... but I assumed that I didn't hurt anything. Should I be worried?

Head distorts a teeny bit when torqued onto block. Same reason proper bore honing requires a deck plate. Stuff flexes.
Set lash off the block and the clearances will be off when you torque it to the block.

well, hopefully I have enough shims now that I’ll be able to account for the true lash measurements once the head is on the block
