Thanks for all your help Dimitri, I couldn't of done it with out you.  I have a  local auto electrician that I use when needed, you know alternators etc. I asked him if he would wire up my race car. He say yer about $2000.00 . Ok see you later.    I knew enough to get most stuff sorted, and was great to get  Dimitri in on the car. Thanks again mate.
      Now that all the wiring was  done. The plan was to vinyal wrap it in the Carbon wrap.  So all the dash and switcher had to come out. Wow. What a job, I taped and marked every thing. The Vinyal wrap made it look better than I thought. After it was all put back together it was starting to come together.
  The shed time was going through the roof, not just weekend but after work.

I even painted the door trims I cut out of thin MDF like plywood . Fitted up my light weight mirrors from eBay .

Clever way of doing the fuel cell cover and filler and a very neat job.  Great work!

With the zed nearing completion, it was time to go over the suspension and bleed brakes etc.  the rear wing had been tested on the red zed and worked really well. Maybe to good. It gave instant under steer. I dialled most of it out with some carpentry work on a front splitter. This set up was to assist me when making the race car aero add ons.
  I also wanted to get the car log booked through Cams.  On the Web site there is a list of scrutineers, . The idea was to get someone to look at the car before it was ready to race. After getting in contact with John. We made a time and he came out after hours to have a pre inspection. A few things were noted.  Front tow hook, fire extinguisher . And the main thing was, he wanted a diagonal roof bar in the rollcage . From front driver side to rear passenger side.
Not much head room in the Zeds at the best of times. Passengers head room has lost about 60mm now.
Anyway all this was done. And John came over and gave it the OK.  So now I have the log book.
    Some pics of the red zed and added aero.

Thanks for all the complements Guys.  I've enjoy sharing the build with you guys. I wasn't going to do a build thread, but a few people had asked me what was happening with the car, so this was the best way to tell the story.
      The engine bay was now complete .  And a picture of the dash and console .
    Regards Gordo.

I was happy with how the zed looked. But it was always a plan to give it a bit of bling. With road cars its better not to attract unwanted attention from hoons wanting a drag or the police pulling you over to take a look.
  But been a race car I wanted to ad some Datsun type stripes.  Sifting through lots of pics on the web I found bits of stuff I liked , but not a full car I would copy.  And some stuff was Awsome , but way beyond my capabilitys.  So the red and blue strips got the go ahead. Finding the centre of the car and useing a pencil to Mark the edge of the centre stripe was easy.  But getting the stripes to follow the contours on the bonnet required patients and a little help from a heat gun to stretch the  vinyl .
  There's a picture of a Porsche rear wing that inspired my up rights.
  And the strips been done.

Time to try and balance the front of the car with a splitter. With the race car about 150mm wider ( flared gards) than the red zed a new splitter would have to be made. It was important to find the finished ride hight with the car so I could determine the splitter hight. I recently went the the Australian GT champs at PI. Looked at all the splitter for inspiration . Wearing my work boots I would slide my tow under the front lip of each car and found most of the cars were between 60 to 80mm from the ground. So this was my starting point.
    The front spoiler was 140mm from the ground , that left me a 70mm gap to fill. I found myself looking at all the cars on the road that had a rounded front bumper bar that I could cut down to fill the gap from spoiler to my plywood splitter.  A trip to pick apart found the VT Commodore had the most suited curve. $20. 
  The black is the bottom of the VT bar upside down. and the red is cut from the VT bumper.
      I used alloy flat bar mounted on the factory bumper bar bolt holes for external front supports.
  The pictures tell the story.

So now with the zed as good as finished. It's time to give it a shake down and find out what works and what needs work!  A PIARC sprint was coming up with a Saturday practice , and if its still running a Sunday sprint. Sounds good to me. With my entry excepted , I would have two weeks to give the car a final going over.  The car would not go on the trailer with the splitter fitted.. But I already knew that. I made it so it was easily fitted and removed.

    The last thing I wanted to do was put some vinyl decals on the side of the car. I had always liked the stripe on the Porsches . As per pic. So I bought a small roll of vinyl and cut every piece . Marking out the side of the car with pencil and ruler.
    I also put a spares package together for race days.  Stuff I might need.  Like Brake fluid, assorted rubber hoses and hose clamps, nuts and bolts , plugs , leads, coil, race tape, tie wire, etc.  The  car would use between 10 and 15lt of fuel , depending on how long the session went. So 3 Jerry cans were requid.

First Aussie S30 I've seen with a letter box slot for the radiator air intake, that should reduce drag and lift. More good thinking there Gordo  :)

Thanks Richard, I tried this last year.  It was only about 25deg, but didn't affect the car temp.

Awesome work Gordo. I was also at the Australian GT champs watching my mate Dale Paterson in the DPM GT3 Camaro, would've been good to catch up, may be next time.

With race day (weekend) approaching fast, I gave the trailer the once over.
    7.15 am at the Phillip Island race track and it was about 6deg and foggy.  Rolled the car off the trailer and screwed the front splitter on. A few friends came over and did the walk around. The first time people had seen the car. It was nice to get a good reaction .  Scruteenering went well. I was in the second practice group. I have to say I was a little nerves. Lots of things could go wrong, but I had preperd well , but I will,still take it nice and slow and get my confidence with the zed. The first thing I noticed was how slippery the slick tires are on the first two laps. Also the brake performance was weard . They just didn't work. As hard as I pushed I couldn't get them to bight hard. I found myself braking way early and standing on the pedal as hard as I could. I actually came into Honda corner with no cars behind me and tried to lock up the wheels. Not even close. I couldn't do it all weekend , the brake pedal was as hard as a rock.
  But the aero was great. I could go faster through the fast corners once the tires warmed up than ever before.
The morning sessions track temp was below 10 deg. It wasn't till the afternoon when the sun came out and track temp went to 20 deg , that the tires worked a bit better.  My son timed me at 1.49s I was happy with that.
  But the brakes and tires would need some working out. Anyway, Sprint day was next.

      We were confronted with the same weather conditions. Very cold start.  I rolled onto the weight bridge at scrutineering. Was a little surprised at the weight, thought I might come in a bit lighter.  1020kg.
But when I thought about it it's got 40kg of roll cage, massive wheels, 15kg front splitter. Petrol tank cover and heavy brackets holding it up and electric powersteering .

  So the first session was cold and no tire temp. Temp gun on the tires was only 30 deg. So I temped the rear disc, only 40 deg and the front 60deg. Say what. Normally there off the scale. This wasnt helping  the tire temp.
Normally the brakes build heat into the wheels, and this transfers to the tires. NOT HAPPENING.

Over all the car was good. Spring rates worked. No vibrations , turn in was good, understeer , over steer was natural . But did notice the R32  Diff wasn't working, was single spinning over Lukey Hights.
Ended up with a  high 1.48s.  Happy to get through the weekend .

  The pedal box is having the master cylinders changed for more pad pressure. So I'm hoping that will fix the brakes, and with any luck help the tire temps. The diff I'm going to leave for another time.

The zed has hit the track, so the fun has just begun.  It's race ready. But it will never be FINISHED!!
        Hope you enjoyed the journey . I will be back on the track in about 4 weeks.  Cheers.

  Some pics from the weekend.

This car went to exactly the right person!
Have no doubt you'll have the issues sorted and breaking records soon enough. And it looks amazeballs!
But I must say........... 15kg splitter? ???

Looks great on the track Gordo. So once you get the brakes sorted and the diff, what sort of times around P.I do you wish to achieve? i know there are other factors that come in to play, temp, track temp, slicks or semi's.

Hi John. Having had the car on the track only once. There are a few things to get sorted. It's a never ending search for the perfect set up. And sometimes you don't even know if you've got it or not. Time will tell.
  But I would expect there could be another 2 or 3 seconds buy the end of the year.  It just depends how well I can read the cars setup. You know , finding the sweet spot.  When are you coming out for a play?
