Any further details on LPG kits for R33 Skylines ?

I know there are Injector kits out on the market now for naturally aspirated vehicles like Ford and Holden.

Anything for the Turbo category ?

yes one company is developing it for sale soon, the test car an XR6T with about 360rwkw. cant remember what company though, i'll have to dig up the magazine article

i had my last car, an 87 NA supra, using LPG...

i swore to myself that i would never go LPG again..

the fitting of hte system had teething problems and didn't iron out for a few months

then there's the fact that a full tank gives you no mileage.. i used to fill up 3 times a week... what a damn hassle and waste of time

plus there's the loss of power. that's right power was noticeable reduced don't kid yourself. i have heard many ppl say that LPG produces the same power and that is rubbish

stay away!

my mate has a HQ caprice which had a 308 worked with 280Hp on LPG (~300Hp on petrol) and that car is damn fast. He built the thing to run on lpg, and its done 1million kms...(around the clock numerous times)

That is a damn fast car for its age, and the kms done. It does need a freshen up due to the kms, but still...im impressed :rofl:

i used to have a turbo rx3 that was lpg only and it went like a cat with deep heat on its nuts . gas and turbo;s actually go very well together the secret is getting it done by someone who knows what there doing not ya local lpg fitter that just does xf falcons and hq holdens .there are a lot of guys with performance cars running lpg. well i even seen a v8 range rover running a turbo and the gas going thru a 500 holley so it does work trouble is there are so many myths and half truths and just miss informed people who have this lpg attitude is crap mindset . find the right guy who is into performace lpg conversions and you might just be surprised

any proven facts about this LPG is as good as petrol or wat???

i want to believe it but not unless i see proof i heard that gas has a higher octane than petrol is that true??

i agree wid ryan 100% about selling ur car if u dont like the fuel bill but bro prices just keep going up its rediculess

well one of the people who i learnt from, told me that LPG is pretty damn good as a fuel. where now you pay $150 for 98 octane unleaded, i believe LPG is around 110 or 114 (just from memory, but could be wrong) if anyone knows for sure its octane, please let me know.

another bonus was its tuneability, or the lack of, as it would happily run from stupidly rich, to stupidly lean by petrol standards.

i think the biggest drawback at the moment is the lack of developement, and with the developement there is now, injectors still arent big enough to supply enough gas for serious power.

mid life crisis, did you ever have your car featured, as i'm sure i've seen one or two of those old rotors running LPG, quite succesfully

Correct me if im wrong but running a turbo car on gas is like being a bodybuilder on a vegie diet.

Sorry for offtopic but some of the best bodybuilders in the past have been vegetarian (before it became all about your chemist, not about your diet). Check out Bill Pearl and Boyer Coe, two legends of bodybuilding, both of whom are vegetarian.

Personally i find it so much easier to build muscle on a vegetarian diet than on a meat one. As long as you have protein powder its fine, thats vegetarian (soy based).

On topic, I own an R33 GTS. Any idea on the costs of converting it to LPG? Its just a straight six so it should be pretty close to the N/A fords and holdens that get converted all the time, right?

I don't know much about the RB25DET but with some engines LPG causes cylinder head wear and valve seat issues. Petrol lubricates the combustion chamber, which is something that LPG does not do, so if your running straight gas then you will need to do more maintenence, more often. Plus the fact that is has about 22 mj/litre compared to around 33 mj/litre for petrol means that you need to burn more for the same power.

My mothers Falcon had LPG on it, it was gutless on LPG, I don't care what any body says if you run duel fuel you will have less power on LPG.

For a car such a Skyline, which is not the thirstiest vehicle around anyway, I wouldn't bother with it, you might save a bit of money, but if money was the primary factor you would be driving a Corolla.

/end rant

LPG can be a good thing or a bad thing. 20 years ago octane ratings were around the 110 mark, now todays figures around the 94, which is pretty disappointing. The alloy head on the rb series motors would mean that the valve seats are already hardened, but its still a good idea to run a lubrication system to prevent VSR (Valve Seat Recession) and its a good idea if you've got dual fuel to run 2 tanks gas to 1 tank petrol to prevent fuel going off in tank and help to lube top end of engine.

I have seen some cars that run only on LPG return some very respectable figures from an sr20 220-230rwkw through to a blown 350 chev with no traction in any of its 3 forward gears! the down side is the amount of fuel needed to get these figures being in some cases twice as much as petrol, so when you add it all up its 6 of one half a dozen of the other not to mention where you fit a reasonably sized tank in an R33!

Don't know if I'm supposed to metion names, so I won't, but there is a place in Melbourne that has done great things with forced induction and LPG and also LPG injection. The money you might spend on injectors, fuel pumps and aftermarket EMS could be used to set up such a system!

It all comes down to one's preference really at the end of the day performance is the goal and you could go either way.

Cheers.

    • OK, so regardless of whether you did Step 1 - Spill Step 2 - Trans pan removal Step 3 - TCM removal we are on to the clean and refill. First, have a good look at the oil pan. While you might see dirty oil and some carbony build up (I did), what you don't want to see is any metal particles on the magnets, or sparkles in the oil (thankfully not). Give it all a good clean, particularly the magnets, and put the new gasket on if you have one (or, just cross your fingers)
    • One other thing to mention from my car before we reassemble and refill. Per that earlier diagram,   There should be 2x B length (40mm) and 6x C length (54mm). So I had incorrectly removed one extra bolt, which I assume was 40mm, but even so I have 4x B and 5x C.  Either, the factory made an assembly error (very unlikely), or someone had been in there before me. I vote for the latter because the TCM part number doesn't match my build date, I suspect the TCM was changed under warranty. This indeed led to much unbolting, rebolting, checking, measuring and swearing under the car.... In the end I left out 1x B bolt and put in a 54mm M6 bolt I already had to make sure it was all correct
    • A couple of notes about the TCM. Firstly, it is integrated into the valve body. If you need to replace the TCM for any reason you are following the procedure above The seppos say these fail all the time. I haven't seen or heard of one on here or locally, but that doesn't mean it can't happen. Finally, Ecutek are now offering tuning for the 7 speed TCM. It is basically like ECU tuning in that you have to buy a license for the computer, and then known parameters can be reset. This is all very new and at the moment they are focussing on more aggressive gear holding in sports or sports+ mode, 2 gear launches for drag racing etc. It doesn't seem to affect shift speed like you can on some transmissions. Importantly for me, by having controllable shift points you can now raise the shift point as well as the ECU rev limit, together allowing it to rev a little higher when that is useful. In manual mode, my car shifts up automatically regardless of what I do which is good (because I don't have to worry about it) but bad (because I can't choose to rev a little higher when convenient).  TCMs can only be tuned from late 2016 onwards, and mine is apparently not one of those although the car build date was August 2016 (presumably a batch of ADM cars were done together, so this will probably be the situation for most ADM cars). No idea about JDM cars, and I'm looking into importing a later model valve body I can swap in. This is the top of my TCM A couple of numbers but no part number. Amayama can't find my specific car but it does say the following for Asia-RHD (interestingly, all out of stock....): So it looks like programable TCM are probably post September 2018 for "Asia RHD". When I read my part number out from Ecutek it was 31705-75X6D which did not match Amayama for my build date (Aug-2016)
    • OK, Step 3, if you need to remove the valve body, either to replace it, the TCM, or to do a more complete drain.  First, you need to disconnect the TCM input wires, they are about half way up the transmission on the drivers side. One plug and the wires are out of the way, but there is also a spring clip that stops the socket from sliding back into the transmission. On my car the spring clip was easy to get, but the socket was really stuck in the o-ring of the transmission housing and took some.....persuasion. You can see both the plug to remove (first) and the spring clip (second) in this pic Incidentally, right next to the plug, you can see where the casting has allowance for a dispstick/filler which Nissan decided not to provide. there is a cap held on with a 6mm head bolt that you can remove to overfill it (AMS recommend a 1.5l overfill). Final step before the big mess, remove the speed sensor that is clipped to the valve body at the rear of the box.  Then removal of the Valve Body. For this the USDM Q50 workshop manual has a critical diagram: There are a billion bolts visible. Almost all of them do not need to be removed, just the 14 shown on the diagram. Even so, I both removed one extra, and didn't check which length bolt came from which location (more on that later....). Again it is worth undoing the 4 corners first, but leaving them a couple of turns in to hold the unit up....gravity is not your friend here and trans oil will be going everywhere. Once the corners are loose but still in remove all the other 10 bolts, then hold the valve body up with 1 hand while removing the final 4. Then, everything just comes free easily, or like in my case you start swearing because that plug is stuck in the casing. Done, the valve body and TCM are out
    • OK, so if you are either going for the bigger fluid change or are changing the valve body which includes the Transmission Control Module (TCM), first you should have both a new gasket 31397-1XJ0A and a torque wrench that can work down to 8Nm (very low, probably a 1/4 drive one). You can probably get by without either, but I really didn't want to pull it all apart together due to a leak. First, you now need that big oil pan. The transmission pan is 450 long x 350 wide, and it will probably leak on all sides, so get ready for a mess. There are 24x 6mm headed bolts holding the pan on. I undid the 2 rear corners, then screwed those bolts back in a couple of turns to let the pan go low at that end, then removed all the middle bolts on each side. Then, undo the front corner bolts slowly while holding the pan up, and 80% of the fluid will head out the rear. From there, remove the remaining bolts and the pan is off. You can see it is still dripping oil absolutely everywhere...it dripped all night.... I got another couple of litres when I removed the pan, and then another few when I removed the valve body - all up another 4l on top of the 3 already dropped in step 1.
