you know I never knew that button was there. back on topic slightly. @Seedy Al why convert from (I'm assuming) live axle and leaves to IRS. Crown wagons aren't fast enough to benefit from the improved cornering. Unless its Massive turbo 2JZ-GTE.  

It's brake calliper overhaul time. I had the same problem. Freed the up by working the piston and slider a bit. Month or so down the track they seized up again. Pull the caliper to bits. Sand blast the housing and put new seals and dust boots in. Replace the pistons too if they are pitted. 2 front calipers on my crown cost about $110 with new pistons. 

Had a bit of spare time on my hands so I decided it was time for a little work on the mighty Golf. First port of call was removing the carb and giving it a damn good clean because the car has been running like shit for the past couple months. I cut out a new gasket for the 2 halves of the carb but was lazy with everything else and used grey RTV. Next was breaking out the Bosch one way lowering kit. having a extra set of springs from the parts car comes in handy about now. After a bit of measuring I thought lopping a coil out of each spring was a good start. I could probably take another coil out of the rear springs but the fronts will no longer be captive if I make them any smaller. I should just stop being cheep and get a set of coilovers if I want to go lower. It hasn't made a huge amount of difference but the rear end has come down getting rid of the "Stink Bug" stance.

This has probably been asked numerous times but I can't find any info anywhere. Is it legal to paint a white/black number plate black and silver to look like the pre 86 plates?

QCR? 

i thought they only dealt in mopeds. 

I suggested this to @Ben_10. We should organise some OS motorcycle meets. So let's have a roll call of the 2 wheel lovers in the Christchurch area. 

I'm going to have to give this one a miss. I've got another event on at the same time and I still haven't worked out how to be in 2 places at once.

Wow, I had to go to page 4 to find this thread. 

I'm not sure where I got this info but I thought I'd share it. 

First of all some basic info about the F series Diff.

Crown Wheel: 7.5"

Braking: Drum and Disc variations

RA65 Celica = Drum
RT142 Corona IRS = Solid Disc
MA61 Supra = Vented disc
MX73 Cressida = Vented Disc
YR22 Tarago = Drum
MS112 Crown = Drum
Corona Mk2 = Drum

RT142 live axle borgwarner discs can be adopted (semi) easily onto some F and T diffs

F series ratio info here on Toymods too.

Example: F372 = 7.5" 3.58 final ratio 2 pinion diff. Will not be stamped on the diff, you will have to check the build plate on the firewall of the car you pull it from.

LSD Availability: Altezza LSD's form the likes of Kaaz etc will bolt in but a spacer ring needs to be made up for it to work. Can anyone shed more light on this? Steroidchickens?

Tomei Altezza centre into an MS112 Crown = Works, no problem!
Cusco Altezza centre into YR22 Tarago = Success!

IRS centres will bolt straight into Live axle F diffs so you could use an MA61 LSD but apparently no good for proper driving with small clutch plates and small surface area they aren't very effective and usually well worn out. An aftermarket 1.5 or 2 way or locker is your best bet for grip or drift work. See Kaaz, Tomei, OS Giken, Cusco, (TRD no longer available)

Side note for celica/cressida/irs corona - Altezza/RS2000 Cusco LSD was a nightmare for my diff guy into RT142/RA65 IRS centre probably due to the car not being LSD to begin with. Machining and lots of hunting for correct bearings needed. Have been told (but can't confirm) that the MA61 diff centre half shafts are needed as they were lsd from factory and are shorter to suit.

Torsen and Truetracs LSD's are also available. Many hilux 4wd live axle ran 7.5" FRONT diffs too 80 and 90's, possibly 2000's. Lots of options from 4 wheel drive aftermarket companies.

Cars:

MX13 Cessida - 3.9 - 1410mm (Same width as T series/S series/KE70 BW)

Tarago YR22 - 4.1 manual and 4.3 auto - 1435mm
Uses a G series (Hilux) diff nose flange bolt pattern (60x60mm) All other F series is 55x55mm)

Crowns:

MS110 Solid Axle (coils) F362: 7.5", 4.77:1, 2 pinions, Open
5x114.3 1450mm Solid disc 

MS112 Solid Axle (coils) F292: 7.5", 4.10:1, 2 pinions, Open
5x114.3 1450mm Solid disc 

MS123 Semi trailing arm IRS F285: 7.5", 4.30:1, 4 pinions,
Clutch LSD 5x114.3 N/A Ventilated disc, 1 piston calipers 

MS50 Solid Axle (leaf) F292: 7.5", 4.10:1, 2 pinions, Open
5x114.3 unknown Drum

Ok the skinny is I'm building a 1G-GE for my crown wagon and I need to look at one in a car to see how the likes of plumbing and wiring go together. Preferably in Christchurch this weekend. Can anyone help an OS brother out?

What was this event? /I should have joined in

The VCC P rally. Cars 1932 - 1987. It was a great run that went through Christchurch and round the bays. Had a couple cars overheat, including my golf. 

A few snaps from the last week. 

low km 325 E30 2 door manual.

Very low km and original series 1 RX7 Savanna 

A recently restored CB750 cop bike that showed up at work.

Very low km and original series 1 Savanna out on the VCC P Rally last weekend  

If anyone cares the F1 qualifying was good, couple can outs and a car destroyed.

only milk and juice comes in 2 litres MEIGHT

I'd be a little worried if my milk jug was pressurized to 40 pound.

Keen as for southland trip, make it saturday so I can get home at a reasonable hour. I might have the new engine in the crown by then. 

By contrast I had a trouble free trip back. Found someone to race from ranfurly to Palmerston. Now I need to sort going back to retrieve mine and @Nick Ritchie's new projects. Cheers for an epic day guys! 

Fucking Murphy's law. Car seems to be starving if fuel at 100. I hope it's the filter.

I have my camera and gopro batteries on charge now so hopefully I remember to take them...

charging/clearing mine as we speak. Should get some good footage of Dansey's Pass.

In a world of old cars the man who has the tools is king. 

I'll be singing off key. 

Have we got a meet up point in Ranfurly? It seems a growing portion of us aren't traveling with the main group.  

I've recently had my hearing rejuvenated so I'll either have to pack ear plugs or add a muffler for the journey. #LoudLYF 

40 grit flap wheel on a grinder. Just watch out for flying chunks, they hurt. 

Or is it really high racing compression?
