View Full Version : '81 RN46 Hilux

15-08-11, 07:10 PM
Just bought my first 4x4, not planning to do anything too extreme to it, just wanted something I could shuttle my mountainbike with and not be precious about.

So... Its a 1981 RN46 long wheelbase single cab, looks to be on original 18R-C (bit rattly when hot), looks like it might be an SR5 model as its got the tacho dash, bucket seats, 31x10.5s on 15x8" rims. Pretty unmolested from the looks really, biggest hack I can see is an aftermarket heater tap and heaps of gay vinyl stickers on the glass and bonnet. All the rust I can find is a 5c piece sized patch under the rear flare on one side.




I wouldn't mind some 15x10s and 33x12.5s, 2" lift, freshen up the motor and paint maybe, but don't want to go nuts on it.

LN46 SR-5 next to it wasn't for sale unfortunately, but then again it was a rust bucket.

Cool. Don't see many like that any more.

Cool reminds me of the Tamiya RC Hilux

I always wanted a Tamiya Mountaineer when I was a kid. This was cheaper.

So drivers seat is royally rooted, like I'm almost sitting on the floor. Anyone know if later model ones interchange?

Nice pickup Mark, not often you see those in good nick anymore

Love it!! I had one too with a car by Turbo setup on it :D

Well today I fixed the battery issue (badly corroded earth terminal), tightened up the steering box a bit (might have a 2nd crack at it though) and peeled a LOT of the crap off it including the front roo bar which was held on with two bolts, front and rear driving lights which weren't hooked up, and various bogan vinyls.
Death rattle turned out to be alternator currently held on by a long bolt with no threads just sitting there (Position of belt being the only thing stopping it falling out), missing spacer washers...rattle rattle.


Next job is drivers seat, I'm like 4" off the floor and its a shitty position. I'm thinking adapting my Recaro LS is the go.

Been driving it a fair bit, pretty happy so far...

But now the parts hunt begins.
Need to find a better dash top, this one is even too butchered for the dash reconditioning mobs.

Badly need to find a heater box plus ducts and control cables; finally figured out why only one windscreen demist vent was hooked up, and the heater hose routing goes via Sydney and Alice Springs, that would be because its got an RN25 heater box. :knock:

Its a little bit annoying, because everything stock is great, but the butchered farm fettled bits are just :wayned:

Also, what the HELL is up with prices for Aussie made 4x4 stuff? Tube bumper from snake racing? $1540! Marlin Crawler tube bumper (USA) $365USD. Looking at 4x4 suppliers sites I am almost certain now that they just charge based on how expensive your car is, i.e. a bar for a GU is 50% more expensive than a near identical one for a GQ.
Are they just banking on 4x4ers all being cashed up bogan tradies/middle aged men?

Took it out to a recreation reserve today, did a nice variety of tracks, got some pics.






Went up with a mate in a turbo diesel bravo with diff locks, and another in a TD Rodeo, I just chugged up and over everything, no fuss, even stuff which had the bravo all locked in.
Only hiccups were a numberplate coming loose (only had one screw in it) and getting the dizzy wet in one of the bigger holes (coughed my way up and out on 2 cylinders anyway!).So it seems pretty decent for a 30 year old, stock fourby!

Standard articulation seems quite good for a leaf sprung ute.

Very cool piece of old J tin.

Nice old ute, I learnt to drive in one of these on my grandparents farm. You sit with your legs straight out in front of you, seat pretty much on the floor.

For all Hilux owners.

Marlin have lots of good stuff. I'm especially keen on their 4.7 t-case gears.

Got some new boots;


Pick up a rear LSD tomorrow, will order front auto locker maybe next week. Getting the last few bits together for body lift (fuel filler hose, making some radiator drop brackets, making some bumper lift brackets etc). Ordering some rancho rs5000s for it in the coming weeks.

Picked up a near uncracked dash the other day too (small - i.e. 5mm long - splits around one vent cutout, will vinyl weld up fine, where as mine has huge cracks and the whole speaker grille is awol).

fuck this thread and this car in the arse...after seeing that last picture I STUPIDLY want to buy another old one, jack it up and whack rediculously oversized rubber on it

that looks totally awesomesauce mate

06-07-12, 10:12 PM
Haha cheers!

35s would be easy with 50mm body lift and light trim of the lower front wheelarch area. I reckon 37s would piss it in with a little more suspension lift...

07-07-12, 11:24 AM
I've got an old US magazine that lists all the tricks with setting these things up. One thing they mention is you can't go too tall in suspension lift because of the transmission length, iirc it's too short which causes driveshaft issues.

07-07-12, 06:48 PM
Would love to see a scan of that?

My front shaft will flex apart now, needs a spacer before I wheel it hard.

07-07-12, 08:15 PM
Chris' 35's hit the springs on full lock [on the bitumen, not offroad]...needs spacers.

10-07-12, 03:30 PM
Yeah these are only 33x12.5s, so far so good except for hitting the front edge of the guards at full lock. Little trimming or body lift will fix that. Heaps of room to springs, and surprisingly heaps to the back of the guards.

Has it broken down, or did you go fishing? I also noted the lack of M1300 sticker. ;)

16-07-12, 10:12 PM
This 18R-C has rattled its last unfortunately. Broke the top timing chain, lunched the tensioner etc and spat most of it out through the timing case.

Looking for a 22R now. Pretty much all that I can afford to fit as anything else (3RZ etc) means swap to 5 speed box, new driveshafts, mounts etc etc.
