Looks alot like a Normal HR31, But is that motor A carby RB30? or Maybe an Rb20e?

RB30S. We don't get any Skylines with a RB30E nor RB30ET. Just a High spec RB30S or low spec CA20S.

Hi Teng,

The engine cover looks like all our RB30 motors, i.e. single cam RB Motor (not a CA). All RB Engined cars in Australia (both GM Holden and Nissan) were EFI (i.e. RB30E). The only cars available directly from a Nissan dealer with a twin cam RB motor are the R32/33 GTR Skylines, with RB26DETT. There are many RB20DET and RB25DET cars in Australia, but they have all been imported as used cars from Japan.

The Interior shots look like a Series 1 R31 Skyline.

Almost all R31s in Australia had solid (live) rear axle. Only the HR31 (i.e. rare 2 door) had Independant Rear Suspension.

Cheers,

Daewoo

Sorry to hijack thread,

How come they chose to have live axle in Australia?

It seems quite odd seeing as my car (C210) and even the C110 all have IRS and R31 being newer should really continue that.

I searched all over and it seems Australia didn't have the coupe version (2-door). Even the GTS is a 4-door version. Why is that? I did find out that there are numerous trim levels from Japan and Australia versions. The RB30S is not sold in Japan and more like a export model which is why we can't get any information or parts from Japan. Even FAST doesn't work with any of the vins which has the RB30S Engines.

Over here we get the;

PJR31 CA20S 4-door

CR31 RB30S 4-door

KCR31 RB30S 2-door which is the one i have, as pictured above.

I think its possibly due to a small market here for the R31 back in the day. They didn't sell as well as the VL commodore. Im pretty sure the top of the line model sold for about $30,000 back in the 80's which back then you could have bough a house for in some areas.

What exactly did you want to know about them?

Just information on the EFI system on the RB30E. Maybe doing a conversion next year and i will need to source alot of parts from Australia. The intake manifold from a VL is the same as that on the R31 so that's settled as i have one here at a local wreck about 100km from where i am lol but that' about it. Other things like injectors, ecu, full uncut wiring harness, sensors, afm, airbox and the lists go on. But i'm getting there slowly. lol

Thanks for most of your informations.

You can buy an R31 for almost nothing if all you want are parts... what we call wreckers, 'auto parts recyclers' will charge you a fortune if you buy bits and pieces, but you can buy a whole car for $Au500 easy... much easier than worrying about which parts from a Holden VL will fit a Nissan R31, when you can easily buy the whole Nissan R31 and get all the bits you need...

While it is true that the VL Commodore outsold the R31 Skyline by a lot, there are still plenty of Skylines about... Also, because Holden are shit, when they put the RB30 into the Comodore, they put the head lower than the top tank of the radiator... VLs always got air in the system and blew head gaskets while Skylines didn't... That is the Aussie Car Industry for you, can even take someone elses reliable engine and screw it up... so there are probably more Skylines on the road now than VLs...

Computer, Loom, Manifold(s), throttle linkages, Fuel Pump.

Often non-EFI cars don't have a return fuel line, so check your car...

I am sure this would be the easiest conversion you could do, and unless you are running multiple carburetors now, should give much better drivability and some horsepower gains...

Would it be difficult/expensive to import a whole cheap standard parts car into Brunei??? might not be worthwhile, (assuming you would pay a few thousand in shipping)... Otherwise, buy one on eBay in Western Australia, jump on a plane with your tools, drive it to the airport car park, strip it and leave it :lol:

Cheers,

Daewoo

Importing a car for parts is outta the question. The laws are quite strict here especially when i don't have an import licence and it's not easy to obtain one either.

When the time comes to salvage parts, i hope someone here at SAU will help me gather the bits and pieces that i need to convert it to EFI and turbo. I will need someone with access to both R31 and VL parts.

Will make a new thread when the time comes. Be sure to find a big box cause it will be filled up. lol

I didn't realise you were thinkng RB30ET...

If you were doing that, I would be thinking of going RB25DET or RB26DETT....

Yeah, well RB30ET will be unique here as there is no such engine here. Plus it will be on a KCR31 coupe.

Maybe easier to just buy and RB25 head and everything and convert your bottom end than find and RB30ET...

Not sure how difficult fitting the turbo manifold etc from a Holden to a Nissan would be..

Should be fairly easy, a lot of GQ patrol drivers throw away the carby and put the EFI manifold and turbo bits on for more power. Will most likely work the exact same way. You're going to get some serious squat in the rear end with all the torque.

I thought the Patrols were L30s, not RB30s...

and all Australia could muster was live axle even 10 years after the japs did IRS on the C210?

You would think Australia could do better than that.

Just a bit of information to add to this;

The government of the day (Bob Hawke) had no choice but to continue with the orders made by the Fraser government 1975~83 that any locally made & sold cars had to have a minimum local content so that they could get the imported parts & cars into Australia with tariff protection (Customs by-laws) and the chosen local diff supplier was Borg Warner and they didn't produce an IRS style diff & LSD's were something of expensive options.

Hence the Aussie R31 had a live BW rear axle, same as Ford & Holden of same era.

Mind you, there is only one Aussie Skyline, it's a bit of a pig except for the Gibson cars S1 & S2 GTS's compared to previous and later models.

Stick with an R30 & you can boast you own the original R34.

Cheers, D

I think my diff is open as well. Will need a LSD option fitted when my project starts. Hard to find one nowadays. Don't know if mine's 25 or 28 spline axle's. Maybe the Australian Silhouette version will fit. I heard it has 28 spline axles.

      Unpeeling the Orange

      Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.

      No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.

      Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).

      I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
