At the moment wanting to buy a 32 for my first car, but theres this thought thats always pushing to the back of my head.... THE PETROL... and when your pumpin turbo through 6 cylinders; tends to drink a bit. But then i remebered some article that was on a current affairs or today tonight or somethin, about some way that you can make your own petrol out of the left over oil that fish and chip deep fryers??? apprently its really healthy.... but i don't know how true that is.. but this thing on TV was aggggggggggesssssss ago. does anybody know anything about this process???

If your impending fuel bill is what's worrying you maybe you aren't prepared for the true cost of owning a Skyline? They are essentially a black hole for money, fuel bills, mods, detailing, servicing - then you'll want to upgrade to a GTR and AARRRGGGHHH!!!!

hehehe but its the best hobby you can have.

nah its not that bad, i know the skylines gonna cost me more than your av car but hey ill find the money, actually the situation isn't that bad , just thought it was worth looking at cos free fuel would be pretty damn cool... guess it was too good to be true then..

funny that you say that, cause Optimax is supposed to be a shit fuel.  

maybe you should stick to the home made stuff :rofl:

Hmm looks like we had a petrochemical expert here with his own lab and everything.

I wouldnt mind knowing the molecular makeup of optimax when you have some spare time

note: this post is very sarcastic.

whic is?....

One thing, RB engines dont run on diesel.

It is made by chemically reacting vegetable oils, animal fats with alcohol and recycled cooking grease/oil. Some bio-diesel is made from domestically produced soybean oil.

It can be made from both new and used vegie oil and animal fats. The fat is chemically reacted with an alcahol ( usually methanol ) to make whats called fatty acid methyl esters. Glycerol is made as a coproduct.

The oils and fats are filtered and preprocessed first to remove water and and contaminants. They are then mixed with the methanol and a catalyst ( sodium or potassium hydroxide ).

The molecules are are broken apart and then reformed into esters and glycerol which are seperated from each other and purified

I dont think you can run an engine straight of bio-diesel. It comes in blends.

B2 is (98% diesel and 2% bio-diesel)

B5 is (95% diesel and 5% bio-diesel)

there are also blends which have 20% bio-diesel (B20)

At the service station ( it still has a fair while before it fully spreads throughout australia ) it would cost around 1.5 times more than straight diesel.

It also has an energy content which is 10% lower than straight diesel. The more you add the less power, torque your engine produces.

Bio-diesel also reduces wear and a mild solvent will clean your fuel system.

I have an issue of "modern MOTOR (may 1974)" – the height of the fuel crisis - which has a formula for making your own petrol. It consists of a blend of :

Toluene (65%)

Benzol (25%)

Naptha (10%) - Heavy naptha, water-white)

Mix the ingredients (by volume) stir and poor in the tank through a strainer (you can get sediment from the naptha occasionally)

This mix is compatible with existing fuel and can be run on its own or in a blend.

This mix was tested on various cars of the day and "they all performed better and gave better economy .. than on either standard or premium octane petrol" - **I would be interested to know the octane rating of this mix, but I guess it must be in the mid nineties**

The article went on to say "we tested this petrol substitute in many vehicles without experiencing any trouble or damage to engine or any other vehicle components." but then went on to say "we accept no responsibility for any damage that might occur" (which makes sense to cover their own backs.

    • I am getting the same issue. Did you resolve it? I just got it after installing my new super coppermix and literally the same issue, new fork, new 18mm carrier, release bearing that came with the kit and replicated the exact same sound. 
    • If you like - I have the STL files so I can email em. There's a couple of gotchas (i.e the holes are not threaded so you might need/will need) to utilize some M3 melt-in threads for some of the points. However if you want to be super accurate, and are willing to remove your calipers and your SHOCKS it's a really good tool. You also might need to scale the part that measures the tyre width a bit wider. It defaults to a 7.5in tyre and I mean who is running that. Luckily with the magic of CAD this is very easy to rescale.
    • jeebus. glad you weren't under it while performing the stunt. Also thanks for the link to the wheel measurer, exactly what I needed
    • In the older stuff there were very significant differences 2wd to 4wd, for example Stagea had strut front end for 2wd and double wishbone for 4wd so it was not minor to swap. From poking around the 2wd v37, it *looks* like it might be more possible; some of the parts specifically have "2wd" stamped on them which suggests the platforms are more similar. You'd still want to start with a 4wd half cut to swap stuff from though. I'd suggest if you don't have a tune on the ECU you don't really need one on the trans either. Throttle mapping is in the ECU side (and you can always use a Roar Pedal if you want the throttle to actually respond to your foot), and really if you are happy with the stock power you probably accept the stock trans behaviour too....its all made to be "sporty" not racey.
    • So, updates. I have not washed the car since it came back from Tassie. I've driven it around a bit but not got around to actually sorting it out. I DID raise it because I cracked the rear bar leaving a hotel which was very distressing. Interestingly, the car drives more compliant now that it's raised a fair bit (5mm front, 15mm rear). Also noticed that my FR height was 10mm lower than FL. So that's now sorted out, too. I also bought this and had it printed: https://www.etsy.com/au/listing/1576422240/wheel-and-tire-fitment-tool-universal?ref=shop_home_feat_1&dd=1&logging_key=08f604d9fa4cc383550ba985e6ac85cd5cac7fbb%3A1576422240 Now, if I was smart I would have taken my brake calipers off to actually use this correctly but it was evident enough to me that in the region where the caliper was... there was nothing to hit suspension/guard/arm wise. So I'm going with "it'll be fine" after using the tool to hopefully very precisely measure the wheel clearance. Also while doing this, I had the very VERY bad idea of jacking one of the wheels/suspension arms up while the rest of the car was on jack stands. I did this to see how the arm would travel. This all was well and good until the car slid off the stands and went through a fence. So don't do that. Incredibly nobody was hurt and there was only minor damage to the rear bumper as the car didn't have far to slide, and had 3-4 wheels on it. The only damage turned out to be the fence itself which was easy to fix, and a little bit of damage to the fibreglass rear bumper trim. I had already planned to try a touch up paint kit to fix the time I drove into my garage door to see if it'd help in the interim before I get it fixed properly. I used the Dr Colorchip kit after looking online and seeing everyone talking about it. Yes it's made for chips and not huge broken missing pieces and I'll be 500% recommending it for stone chips after using it for stupid things like me. This took about ... 10 minutes and looking at the half assed photo the 30 second job I did on the bumper corner was almost perfect just by using the tiny little brush and painting it in. The sealact stuff to remove over-painting is really useful, so if/when I do it again I'll likely slather the touch up paint well over it and then clean it up with the cleaning solution. The wheels should arrive in a couple of weeks. I am still kinda confident after doing a stupid amount of measuring (and borrowing a set of 18x10.5+15) that they will not fit because I overlooked something, somehow and flew too close to the sun. ALSO R34 GTR guard liners do not fit on a GTT. I bought the undertray brake duct guides and had the wonderful problem of them not fitting my intake, my oil cooler and the liners themselves were even worse. Attempting to fit them won't work in general - You would have to cut them up as another poster mentioned as the bodywork is different on the GTT. At least I can try to resell them. So instead of cutting those up, I cut up my old already-cut-up GTT liners and extended them by using some PP plastic and drilling some 8mm holes for some nissan clips for the 'extra' bit. Because I was happy to cut them I was able to mount them pretty damn forward so I now have some semblance of guard liners, and the brake vents seal the bumper from the bottom. It sort-of-looks like this, to give some idea - If you look at the GTR and then the GTT this is when I realised that I needed to seriously measure as the inside of the rim area is entirely, entirely, entirely different and could not take any internet measurements for granted.
