Give me a yell mate if you need an extra pair of of hands to get things done. Keep at it though, maybe a wager on who will get on the road first could spur us both along.
Health problems serve as as a measure of resolve for us all so keep pushing through and bit by bit and one day its suddenly done.

Thanks mate. My struggles are a drop in the ocean to yours. It'll be nice to finish this wiring off. Then I can do the easy put the panels on job. Off to Auto+ to push my driveshafts out of the other hubs so I can swap them over. Always and adventure!

In the process of adding the nb8b booster/master I took the time to clean up the brake fluid eaten paint. Didn't look too bad but a scrape back revealed it was a little more extensive than first thought. Sanded to bare me tail as it was only surface rust and primed with rust etch primer/converter just in case and then a quite a few coats of colour match paint. Checked the windscreen surrounds for any more and they look perfect. No rust on floor or parcel shelf. It's spent most it's life in a shed.

Before



Don't mind the overspray. Mostly from trying to blend it into the existing paint. That's tomorrow's job! Not bad for 2 hours and $25 of paint for another 20 years of happy rust free motoring.

Neat work. I ended up sourcing an NB master/booster combo from the uk after failing to pinch yours.
Settling on using an NB booster and BA astina master cylinder for the extra room it will afford the itbs...though you don't have that problem with that whizzer thing hanging off the other side of the block

I'll probably go down the 929 master route. Need to order some front brakes next, wilwood are looking like the go as I cannot find another set of AP calipers with reasonable rotor sizing as of yet. But $1500 is a chunk of $$ for them.

Between the na and nb they changed the brake fluid light plugs. But simple fix, the sensor simply unclips and slides out!





After that was done I repainted the booster as it was a little rough. Once 90% dry I threw a fan and heat at it to hurry it up...



Installed the booster into the car and then had the fun of installing the new lines. This would be much easier without an engine or with two people! Just need to source some NB clips which have more provision for the lines as they're now on the LHS.



Also picked up a new rear housing for the turbo by chance off ebay!



Next up, more wiring so I can return the RHS loom into the engine bay once again. Once this is complete I'll be able to install all the heater/cooler boxes and the dash. That will free up a bit of space in the garage and feel like I've done something constructive for once!

Today I got distracted. Thought again about a/c. Between myself, mates and my wife it was decided to keep the a/c. Problem presents itself with cooler piping, intercooler placement etc. I know people run small coolers but as almost everything on this project is over complicated it's only natural I'd mess with it. See below. The drier is in the way preventing a wide and tall cooler. The NB moved this up next to the passenger firewall.





The other restriction to pipework is these pipes and the sway bar. By removing the liquid line it will get me valuable spacing.



Before heating anything remember to remove any o rings, schrader valves and sensors. This is the HP switch.





By using ratchet benders you'll avoid kinks! Especially when reusing old pipework.



After desoldering the service port and hp switch I modified the high side like this.



Using the line across the firewall I joined a flare joint to it, added a few bends and ended up with this which sits above the condenser.

I went to red devil and grabbed an old piece of line the same diameter to complete the return line. They don't use this line anymore. It's all flex and crimps. That would take up more room and not be as neat. I also scavenged some larger tube to use a couplings where I needed to join the pieces.



Once completed it will be sleeved in foam to prevent vibration from rubbing through.







Underneath view. I'll remove the bracket too now.



After lot of stuffing around its just waiting for special flux and solder to braze it.

Disclaimer. Handling refrigerant is illegal without an ARCTIK license. Not a diy friendly job for the average Joe which is probably why it's not usually done. Pipe lengths are also crucial to operation. I'm only 100mm short all up which is pretty close and shouldn't pose any trouble. I will relocate the ac relay and hp switch wiring up to the drier location and extend fan wires.

Pulled rear abs hubs apart last night to renew the bearings. It's a fun job!



Adding a bit of heat will expand the carrier and can then be chiseled up using the upper groove without any damage to the steel.



Using the press as a vice is fantastic too.



Picked up new rear bearings too so I can get those abs hubs in!
That's all for today.

A bit more progress
My original fronts comparison.



These required similar fitment as my Astina brake upgrade. Tap out hubs and bolt goes through caliper and into hub.
I needed a 10.8mm drill bit and some high tensile bolts to fix to. (12x1.25)
Pine river bearings could do the bolts but sent me to Advanced engineering. Very helpful businesses. I like to support the small family run stuff if possible. For less than $20 I had 4 bolts and a quality bit.

So it begins.

Not as good as the tub stuff but it gets the job done.


After 1/4 extension allowed me to tap whilst in situ. Worked out great.



One down, fitment was perfect.



I had to trim the bolts down a few mm to clear the rotors but otherwise was easy. Drilled the calipers to 12mm too.

Today I worked on my AC lines again. I received some special brazing rods earlier which look like this.



And this is how they work...







I'm hoping they are crack resistant, they're plenty strong - twisting results in the pipe flexing! Won't know how well they work until I fill the system up with nitrogen and pressurise it

awesome brakes, looks like the caliper is pretty close to the hub part of the disc. What size wheels are they?

[cookie]

15x9 +35 s1 advanti. They look closer than they are due to the angle taken, but they're huge so they do take up alot of real estate. I'm contemplating either superlight or stoptech 42 calipers for the front. 6 pot wilwood look massive but offer little upgrade to the 4 pot version. The superlight pads are actually larger.

Thanks for the speedy reply. Be cool to see if the factory 15s fit over or 6ULs.

I've read that the spacing is 120mm and the smallest "Dim D" measurement i've seen in the Alcons is 130mm, is that 120mm measurement wrong or have I missed where you modified something

[cookie]

The calipers have holes for the bolts to slide through and mount onto spacers/dog bones, or in this case, the hub assembly directly. I had to enlarge holes for the 12x1.25 bolts to fit through, but otherwise bolted right up. The custom hubs is where the magic of alignment happens I guess. I just got them used.

Edit. The material they're made from is extremely nice to drill. You could tell it was quality...the space saver also bolts up too...

4 month update... car is still in pieces. Australia post is terrible, losing the tial housing by delivering to the wrong address... thankfully I was able to track down the seller and got a replacement

Got my manifold, dump a few months back. Only recently got a few clamps and gate for it.

Pretty happy with it although it would have been nice to have the turbo further forward but it's designed around power steering.

It also fouls the suction ac line so after all that, I'm just going to plug it up and deal with it later!

Bought an oil cooler and relocation, Turbosmart oil pressure reg for the turbo, boundary engineering pump and ati balancer...will go in with the cams later.

Waiting on delivery for the cooler then I can get it to a shop for fab work.

See you in a few months
