Moving on I finally got my hot side of the turbo kit cermic coated. It's a shame to cover those fantastic welds but, it's for the greater good. Shot a quick pic when I dropped it off. Ignore the parts under the red x. They're not mine.

The hot side ended up looking great after Ceramic coating.

I also installed a new shorter serpentine belt. Due to my fear that excessive heat would cause my serpentine belt to prematurely fail.

To keep a clean look I chose to relocate my ignition coils. So I purchased Michigan Motorsports ignition coil relocation kit. Unfortunately it wasn't a plug & play install. Even though I had coils that were advertised to fit.  They didn't. Here's some pics showing the Coils not fitting.

After some quick machining they fit perfectly. It's worth noting Michigan Motorsports did issue a reimbursement to cover machining costs. I couldn't be happier with their customer service.

Another preventative step I took was the installation of new sensors & intake manifold gaskets. Also installed new steam port gaskets. The steam port gaskets I used were Dorman #56390. New stainless steel hardware was used to secure the TPS & IAC. The stainless steel hardware specs was M4x.7mm x 12mm & M4 washers. Only thing left is to weld the IAT bung on & install new oil pressure sensor.

Last but not least was the making of the spark plug wires. I didn't want my spark plug wires to take take away from my "clean look". With that said I chose to run them behind the exhaust manifolds. Accel Extreme 9000 wires were chosen. Due to not wanting to deal with melting boots all the time. These wires have cermic boots that withstand 2000 degrees. In kit #9001C the shortest plug wire was 31.5 inches long from the base of the cermic boot. This kit doesn't come with boots for LSX coils. I used Taylor Cable #46069 boots. For extra protection DEI Titanium Protect-A-Sleeve was installed to cover the portions of wire nearest to the exhaust manifolds. 
Pics of the parts used to make my wires. I'm also posting the measurements of all the wires included in the #9001C kit. Maybe it'll help someone that stumbles on my build.

It's so rare for someone to start a project like this with a Z31 and then follow it through to the end, all with multiple pics and done to a high standard. After that I want something  ;) with that last pic it looks like the upper plenum goes back under the firewall horizontal flange, there is a shallow recess in the firewall there. Is that how far back the engine actually goes? I'll find out how far a LS3 with 4L85E auto will go back when that part of my build is reached, be interesting to know what may be possible though.

 

:2thumbs: for yours, and again :2thumbs:

I don't have mine all the way back but it should clear it. Looking forward to your build man!

Woo Hoo! A post holiday's update.  I hope everyone had a fantastic holiday season.  This is one of, if not the busiest time of year for me. Got the regular holidays plus my daughter's birthday. Which is exactly 1 week before Christmas. Makes for a busy finish to the year no mater how much preparation is done.  With the holidays out of the way,  I finally got sometime to spend in the garage. 
 
To kick this update off I removed the kit to gain access to my wastegates. That way I could install my wastegate springs. I paired the green & red springs which should net me around .7 Bar/10.15 Psi.

To make removal/installs go much faster, I opted for some vibrant quick disconnect V-band clamps.

Just a fair warning lube the threaded "bolt" prior to install. I normally do but I forgot to on 1 of them.  Which cause this failure the 1st time I removed it. Another tip is to weld some Stainless Steel threaded stock to replace the threaded rod portion of the V-band.
