Hey guys been awhile since I had a car I could start a build thread on. But here it is!! Complete apart from motor and gearbox .

Its also a manual collium shift !! Linkages still in tact and all . I would been super keen to get that hooked up n bench seat in the front !! Anyone got a gearbox with linkages lying around ?? Think it's suppose to be a 3 speed manual one going by my corona manual

Here's some pics !

Were no holes behind so used a wire wheel on a drill cleaned it up n rust protected it

Ran out of argonshield so decided to grab some dry ice while I was at boc . Floor looked mint but wanted to have a look as some was peeling off on passenger rear foot well

20141115_135717_zpsjobnzfw5.jpg

Dry ice inside rubbish bag . I got 5 kg and had plenty to do it all including the bits in boot

20141115_135722_zpsysnyljqq.jpg

Came off pretty easy . Floor needed no attention at all I cleaned it up n por15 it all . Didn't take any pics though .


Rear arches r rust free and sills are mint aswell what a score !!

Moved foward started on removing aerial holes.


Used abit of tie wire to hold the piece in place while I tacked it in place

Another up date ! Spent few hours this arvo on her .. finished fixing rust around front windscreen .. Here's pics . The rust mission is almost over !!!

As per all the other repairs old owners had done this was no different .. old patch straight over the top of rust they welded it in but didn't bother to cut it out ... lazy assessment

Hey guyz

Spent another day down in the garage .. I decided to start stripping the engine bay to start prepping for paint this is my 1st time n its actually came up pretty good few surface rust bits under where the brake cylinder n stuff was bUT nothing serious what so ever . What's the best way 2 go about prepping it for paint can I grind back those rust bits n scuff the rest removing factory runs in the paint etc .. I also want to paint it myself so I csn re assemble it all to get it going how good of a job is it possible to get using spray cans ??

I want to paint it holden gold which is a factory holden commodore colour. Looks like this -

Couple weeks ago I decided to get my wheels tidied up .. got em back yesterday really happy with how they are now to seal em up n chuck em on car .. Tires being used r 185/55/r14 .. thinking of increasing rears to 205/55 or something of similiar for something decent.. 9" rim

Here's some wheel porn

here's what they orginally looked like

20140822_203836_zpsrvwuhrz5.jpg

Got wheels taken off bead.. Tires r a good fit lol

20150303_135112_zpsgi9mgf3a.jpg

centre's were tigged to the rear lips had em chemically dipped n acid dipped to clean em all up

Even took radiator surround and bonnet hinges to be dipped.

IMG-1425344004822-V_zpsnzbn7uza.jpg

Centre's went off to powdercoaters . Used Brian n Whyte in kingsland nice guys and really well priced . 40 bucks per rim to go metallic gun metal grey and then clearcoated.

Small update . Shortening diff to get wheels to fit on the rear diff needs to be shortened 30 mm each side see how we go

Went with Karlos from steel surgeon manukau . He seems confident he can shorten em that much without any trouble

Small as fuck .

Sorted an engine crane thanks to threeonatree . Legend.

Picked up some mongoose sound deadening Today will start putting it in when I get abit of time for now I wanna prep n paint motor n chuck it in the hole in the hope nothing is wrong hmmm !

If anyone interested the sound deadening was $199 for 9 sheets of 810x400 I think I got an extra 5 though for an additional 120 but she going to be luxurious !

Paint after 24 hours

Update !

So over the weekend and tonight I've been stuffing around trying go get the motor in and running turns out I had forgotten a few bits haha so didn't go so smoothly !

Had to grab 18r engine mounts of donor car as this had a 12 r which were diffeent

20150516_213721_zpss6r87gta.jpg

20150516_150518_zpscug0vggk.jpg

20150516_184248_zpstmhnkui8.jpg

Haha sort of forgot that 18r has front sump and 18rg has rear sump which sits on cross member !!

Shit ..so out came motor again .. Re drain the new oil I just put in n swap sumps . Good news is this engine was perfectly clean no deposits no build ups n was pretty clean throughout.

on the other one it had about 30 mm of build up gunk and little shavings shit !! Took me ages to clean it out n degreazer it thought I'd paint it too

IMG-1431821412894-V_zps9eal250u.jpg

after eventually getting it in and everything hooked up it won't start by key so I've been shortening out the starter to get it turning over !

turns out the battery I had didn't hold charge n was flat .. wasn't able to get it going yesterday ..

Today I started from stratch again thanks to stu and sleektoy for their help .

Turns out had a blown engine fuse

the dizzy to coil lead had like 10 resistance lol so maori'd up another lead off spare car and managed to get spark .

I doubled Checked to see If i had the timing right which I did .

The fuel pump wasn't working propley and was letting bugger all fuel into the carbs ! So I raxed the one off the 18r but was slightly different and the hoses didn't fit propley / leaked everywhere !

I managed to get fuel up into the carbs n plenty of it ! but stopped as getting late

Fuel lines aren't hooked up propley I just had fuel line dropped into a bottle..

motor will he coming back out need to sus a clutch fork just wanna hear it running make sure it's ok .

So tomorrow hopefully pick up my clutch fork.

Get some new fuel lines to get it going

i need a new dizzy to coil lead I might as well just replace em all !

Also the wiring issue I think may be from mis matching the orginial 12 r fuse loom that was in that and I used my 18r engine loom as 12 r was different as and then I used my 18r steering collumn as this car was collumn shift ! It all plugged in propley and I couldn't tell any difference but maybe there is .

When I use the 18r key start I csnt even hear the relay going but when I plug in the 12 r one it makes a sound ?

The 18rgu starter motor is also slightly different with 3 wires coming off starter motor I suspect the 3rd may be ignition ? Which is why it's not key starting possibly .. so I'll also throw in the orginial 18r starter motor which works but only has 2 wires coming off it which was orginally connected to this loom and hopefully it'll be running tomorrow !! and by key

Had another crack at it tonight .. I jewed out and hoped I'd get away without replacing spark plugs n leads .

I checked plugs n seemed ok but everything else seems rather weathered I flattened 3 batteries trying to get it going before accepting my failure of not getting them while at super cheap when I grabbed some hose clamps to stop fuel leaks ... :(

I did however grab another coil to dizzy lead while I was at spartan wreckers grabbing this...

20150519_195559_zpshyonwtlm.jpg

Clutch fork release bearing and bearing carrier . Bearing feels nice so will just give the fork a tidy up re paint n assemble after I get motor running .. my sump also has a small leak only happens when car turns over .. will need to grab a proper gasket since the gasket silicone didn't do the job

I did however manage to get it to run without starter motor for up to 5 seconds a few times but was missing abit n sputtering away .

I had these open which I've been told r for emissions n they should be blocked off will make it run lean so have since done that ..

IMG-1432019115310-V_zpsnwwxu596.jpg

So tomorrow ill grab a proper gasket I need for sump .

new plugs and leads and try again .

Also fully swapped the last of the 18r loom over and still unable to start using key .. I think tomorrow I'll quickly switch starter motors to orginial 18r one n see if that makes a difference .. it use to work fine back in other car n since I've swapped it all other to this i can't see why not.

How it currently sits...

IMG-1432021809479-V_zps8bqrq8ty.jpg

Shit it's lucky I had my co2 extinguisher ready to go .. the float valve on the front carbs must have been stuck n was pissing out fuel onto my arm below it ..

Next thing ! Whooom ! My arms on fire the rubber glove starts melting around my hand and the fuel dripping out of the carbs catches fire to the fuel on the engine bay and all around the 5 litre gas tank I had sitting under the block I was using to start the car ...

Phew !

lucky no damage to paint in engine bay or my arm for that matter ! Could have been bad tho . The float valve has since fixed itself must have been a little stuck n got floaded with petrol for the first time .since half of it was leaking out the dodgy fuel line connections

BOOM !!! got it all running tonight n shit she purs really nice csnt figure out how go post a video on here but I got proof !! I'll post it when I figure it out / someone helps me !!

Also ... some very very good history on this motor I text the fella I brought it off in palmy n he called me back giving me the run down !

Got it off his good mate who was an engineer .

It was imported by his mate the engineer back in the late 80s when he got a few over from japan and was going to make concept cars but this one he never finished.

it was a guranteed good runner with low milage when he imported it from japan it n its never been starting since it got into nz ... Hasn't been started in almost 20 years lol . No wonder when I took the sump off it looked brand new inside ! Not even the smallest bit of build up on the sump.

He also told me his engineer mate always turned it over by hand and when sold to him was always on his case about doing it too !

He said he would be very suprised if the motor and gearbox had done more than 30 000 miles !!

Such awesome news what a brilliant find.

There's only 1 way to celebrate ...

20150520_221147_zpswvnco9xv.jpg

Thanks for looking hOpe i can figure out video soon
