Looking at converting the cef to gas in keeping with it being a taxi...

hehe

seriously, there's a gov't rebate on changing to a gas system... and I know they were used as taxi's in NZ... and all our taxi's run on gas in australia, so maaaaaybe some cef's in NZ run on gas too?

The car's only used for daily driving, and its 99% used by my old man, so performance is not an issue, only reliability and economy.

In any case, can an RB20DET be converted to run on natural gas? will a varying air intake rate (due to turbo) and variable fuel injection (due to EFI) be compatible with a gas system?

Of course once that's done... then the next step would be to convince my old man to run som NAWWWS mixed in with the natural gas for some added wooshka.

No reason why not, but suggest you look at the more sophisticated end of the market which is Gas Research out Hallam way. More expensive, but worth it.

I assume you mean LPG not CNG (natural gas). It's possible to use CNG, but the tank pressures are far higher and it's not common in Oz. Besides the Govt rebate is only for LPG AFAIC.

There's a VL Turbo (in Melb i think) running 10's on straight LPG man... if they can do it then there's no reason you can't.

i think their plates are LPG 747 or something like that, check out commodore forums and someone will point you in the right direction.

**Now: let's never speak of me pointing anyone towards a commmodore again!!**

ahh yes, gas research, that's where Danny (autotrust) on the forums, used to work.

Didn't know they did a VL (it is GAS747 accrding to google). Will call in some favours n see what they can hook me up with.

CC... the conversion is about $3500 for a total system, and the rebate is just under $2000 or so. $1500 is the savings I'd make over petrol if I refilled every week for a year. After that its money in the pocket. Plus once its converted to gas I can drive back n forth between melb n syd too for almost the cost of flying :D

I hope your pimp hand is strong Cislowski! Nothing short of amnesia will make me change my mind... well, unless its way too financially unfeasible.

Besides... first RB engine outside of a Commonwhore to run on gas (altho if u squint teh cef looks like a fully sik calais).

That's the one! absolute machine!

once again, let's erase my commodore references from all our memories before i get bitch slapped lol!

aside from that, I don't see what makes it a bad idea beer baron? gov't rebate + cheaper fuel...

mind you, i don't have a car at the moment so I have no standings on this topic what-so-ever ;) lol!

A mate of mine put LPG into his Patrol, He then towed his Rock Hopper down to Sydney from Ipswich, cost him $300 in Gas, usually around the 600 mark.

He also said there was no lose of power.

funky, i'm sure you will have many a person giving you their two cents,

however, read my thoughts

every man and his dog now wants their car converted to LPG with the gov't rebate, supply and demand concept ensues that fitters of LPG tanks will (and already have in WA) raised their prices to compensate for the gov't rebate and to counter demand with limited supply to the tune of about a $1500 add on to the previous cost,

all fitters in WA are fully booked to do the conversion until may next year, and are refusing to answer any calls,

LPG tanks can only be fitted to a certain types of car, in order for a car that hasn't got a plan for LPG, i believe they have to do a crash test with one in the car, (may not be right there, just what i read in the paper)

realistically, the estimate to actually save money after the conversion is expected to take around 5 yrs with the inflated prices, also, PLG prices are expected to rise somewhat as demand increases, (i doubt that one)

this however is (to me) common sense:

turbo + LPG conversion = turbo eats up LPG and you have to refill much more often,

LPG puts more strain on all engines bescause the ignition isn't as resonsive as petrol, this is the case with NA engine, imagine how much strain a turbo would put on it?

now here's food for thought...

LPG conversion = ~$4000

turbo + LPG increased consumption = more fuel purchases

engine problems to ensue as time goes by = billions and billions of money

long run savings = nothing worth mentioning

IF you want to save on efficiency, and don't give a crap about power,

RB20DE engine = ...$800 i would think?

fuel consumption = good

conversion costs, = $2

savings in long run = billions of moneys + save your dignity of not having a LPG powered car.

to be honest an RB20DET is probably not the most fuel economic engine to start with. Being a turbo engine it chews up ANY fuel, LPG or otherwise.

I could probably get a prius for like 14-15k and fark the ceffy off for 10k.

I've already owned an RB20DE GTS, which did 10k per litre, but it was gutless... so having owned one, I wouldn't wanna go back to one. Theoretically gas systems should be no less efficient than petrol systems. I've driven dual fuel systems, my gf had a dual fuel magna and that was such a pain to use... but I'm told gas only systems these days are sophisticated enough to work properly with no issues.

This is more an exercise in being different, and slightly thinking financially. After having spoken to Gas Research their waiting list is till May next year... but a little bird tells me they might do mine a lil sooner if I go with em :P

      No worries at all 🫡 I think the most satisfying things to make are the little bits that are just impossible to find or they're no longer manufactured. Generally I always try to replace parts with OEM wherever possible. This little project is also great because it'll never see the light of day, but strengthen these brackets so it's not just relying on the little standard screws in the headlight plastic. As soon as I saw the standard brackets and screws I thought, "well I'm not going to install with just the screws, the plastic tabs will just snap off". It's crazy how expensive everything has become yeah. But I suppose that's supply and demand; granted it's a lot easier to get brand new genuine parts these days which is fantastic 😊, I don't have to get totally reamed at the local Nissan dealer ha ha We sure are lucky we have all these manufacturers making parts these days, a few really great Australian companies too like Platinum Racing Products and Fit Mint Automotive, what a time to be alive ❤️ . I've got my eye on the RB26 head by PRP as mine has a very fine hairline crack, so that'll need to be addressed some time in the future. If you have any requests or odd things to make feel free to let me know and I can have a crack at making replacement parts ✌️

      Thanks for sharing this, and BTW if your headlights are in good condition they are worth thousands....you might want to consider replacing them with brand new LED ones like this (https://www.nengun.com/78works/full-led-headlights-r32-skyline) and making enough profit to buy a house in Sydney

      R32 GTS (RB20DE) clogged cat

      By Duncan · Posted

      I'm not sure what sort of shops are nearby, but I'd expect any reasonable exhaust shop could put a cat in it that will not restrict the power that engine makes. Otherwise, if you want to remove it, short lengths that replace the cat are readily available online, search for "de-cat pipes" or "test pipes"

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.
