Mate its about bloody time these kits came out. I've been looking into liquid injection for a few years now with no sucess. I just heard the other day about a liquid injection thing in some mag and my ears pricked up. By far the best way to be going. When i first started looking up these things, i heard of a few trial cars getting about, one being a off tap supercharged V8, making almost 1000hp. That got me really excited!!! Just a few Q's for the tech heads, why is there a pump?? Can't you just use tank pressure?? Whats the diff of 20bar +3??? seems a bit strange Are the injectors just efi fuel injectors with a high pressure hose on the back?? Do the injectors plumb into the efi spots for similar to vapour injection where you drill and tap a hole into the manifold?? just couldn't see from pics. Can we just buy parts and fit it our selves?? (i do all my own work) If we had a prog management does the price come down or is it just $4500 and go from there?? I just think $4500 is a bit rich for a tank(with pump) some lines and a few injectors. or is each injector like $600 ea?? Mate not having a go, just trying to justify where all the money is. Any info would be great. Thanks

hey misk lpg kits r starting to flow through 4 most of the late model stuff, eg falcon and commo. as for rb and 2jz the kits will universal and modified 2 suit. kits are getting more avaliable although the main issue i have is unable 2 get tanks. pricing hasnt changed if any gone up a little. Dj labby the liquid system has a pump to maintain a constant working pressure. the tank has a return to supply a cool flow. this is done so u don't get any frezzing of the injectors. most of the injectors fit up to a installed nipple, similar to gas vapour set ups. u r able to get injectors 2 fit into the oem spots but havnt seen the as yet. most lpg wholesales won't sell u complete kits due to them having 2 be fit by accreditated installers. even if u have a programable ecu ur not gonna c the price come down. the complete kit is expensive. to fit it u require special tooling to make up the hoses, not 2 mention there is a ton of work involved installing a lpg system, wiring, modifying, fabricating, tunning ect. essentially a lpg injection system is like a top dollar petrol system. tank with a fuel pump(can use a walbro if u want!!), supply and return lines, injectors and rail, pressure regulator and the management 2 run it!! benefits r lpg liquid has more bang than fuel, injected super cold lowering intake charge temps and is cheaper..... hope that helps

hm its a shame its not easier to purchase kits or at least parts seperatly from the supplier. i agree there is alot of work to fit a gas system, but i also agree that its not very different to fitting a petrol fuel system, which has been done time and time again by people at home id love to get a tank, ecu & sensors, and few other bits and pieces and basically just have an installed fit the gas lines and injectors and do a tune! but i guess that wont be happening lol

Hey guys I don't want to get anyone too excitied but I have a GQ patrol with an rb30 turbo running the JTG system and putting out nearly 300rkw in a very early stage of tune I used to work for gaspower australia and I installed the first 4 systems in Perth as Gas Power was the first to able to install the systems in WA My patrol is running the system off the VLT ecu with nistune and it has been very suscessful. ATM I am still running the JTG ICM computer for dual fuel but it has been nothing but problems so I am rewiring this weekend removing my petrol injectors and moving my gas injectors into the primary position right infront of the intake valve for best power and economy I have installed approx 14 to 15 systems for gas power before I left to concentrate on the performance side on LPG. Ill just go take some photos of my engine bay and get them up for you Joel Blue Fire Performance Ok here is some photos of my Patrol engine bay. Note this is the first stage in development as I wanted to do some testing before I got carried away. But it has gone well and im starting stage 2 this weekend. I have drawn up a design for a new plenum and I will be starting to rewire the system today for dedicated LPG (http://img23.imageshack.us/my.php?image=pict0058r.jpg) (http://img15.imageshack.us/my.php?image=pict0059z.jpg) (http://img15.imageshack.us/my.php?image=pict0060d.jpg) Joel Blue Fire Performance Some original photos have not been recovered yet.

Wrath: Was it much of a problem to fit on the RB30? What other work have you also had done to make that power?

Any info would be great. Thanks The pump is used to keep the rail pressure at 3+bar above tank pressure to keep the LPG in liquid form, the higher the outside temp the greater the pressure has to be to stop the LPG changing state.. this has been the biggest problem for the developers not freezing as the gas only freezes as it enters the manifold where the pressure is low and the temp is higher. a solinoid is used on the regulator to alow the lpg to circulate the system quickly and purge and vapour that may be in the rail. As for the price DJ its simple economics.... supply and demand everyone wants this system and LPG wherehouse are UNDER THE PUMP atm and your not just paying for the equipment but years of research and devolpment. As for getting the parts yourself.... never going to happen, its a regulated industry and you have to be licensed to even be able to touch most of the LPG equipment. sorry to be a wet blanket but just setting the record straight Quote: Originally Posted by HDT-VLCLE Wrath: Was it much of a problem to fit on the RB30? What other work have you also had done to make that power? Engine is stock N/A turbo is GT3076 with a 6boost manifold and tial wastegate 3" mandrel system that I fabbed up and thats about it. altho im very careful with it as I want to get the setup right before I pull the engine for a rebuild, I just want to shot peen the rods fit ARP rod bolts and a solid head gasket. If all goes well i might increase static compression ratio to 10:1 LPG has a octane rating of 104 to 110 so ratios of up to 11 and 12 can be used but I wouldn't go that high with boost over 10psi I am making a new plenum to move the TB back and allow space for a fusion intercooler ontop of the engine to keep intake air temp to a more consistant level and monday the turbo manifold and dump pipe will be getting ceramic coated to reduce engine bay temps

what about using the nistune as batch fire? i thought you could only use an ecu that has sequential injection with liquid lpg injection ?!

i'm going to assume that he's not running sequential injection with the nistune, only group fire...

The comment was you can use batch but it runs rough apparently as Blownba said. As I said earlier this is stage 1 of my development with this car, the plan was to upgrade the ECU at a later stage but test how the system ran on the standard ECU with batch fire.... and the result.....it runs very well, infact I may not upgrade the ECU. However being a 4WD im not searching for ultimate HP, it has more than I can use on loose terrain so this setup is fine. But of course sequential will give you better power, economy and touque.

First post on your forum.I an looking to buy a liquid injection tank,or multi-valve assy and fuel pump.Also i would like to talk to Blowba if possible. Thankyou

Tomorrow is the release of LPGAS1 new plug and play liquid injection kits. For new cars VE's and FG's, few others aswell, went to a training thing in Melbourne on these kits, look very good, Australian owned and manufactured. Will be fitting them in the next couple of weeks.

abrowne70 Do u have anymore info on the kits or even install pictures??? I hear the kit for VE/BA/BF/FG are $4500.00 RRP, is this true??? Also how flexible is the LPG kit for say a owner in a VE does a cam and exhaust upgrade and need's a retune??? i was told they are fully flexible and it has it's own ecu and can plug in a laptop and calibrate the LPG injectors..........

Here is a nice article detailing the performance potential of liquid propane injection: http://www.mustang50magazine.com/tec...wer/index.html (http://www.mustang50magazine.com/techarticles/m5lp_1007_roush_propane_racer_clean_power/index.html) Basically they run 12.5:1 compression and run in the mid 10's on the 1/4 mile, N/A. Is anyone familiar with these injectors? Some original photos have not been recovered yet.

Im pretty sure kits are about $3500 plus installation. (Dont quote me on that though) Fully Tunable, havent really looked into it yet, but im also led to believe they are fully tuneable. Fuel maps are editable, injectors are able to be calibrated. So im pretty sure there tuneable. I have a manual for installation of a kit at work, when i get back there next week i shall have a look and suss it out for you.

Thanks bud id really appreciate it, and if u have any pictures of injectors and other bits of the kit plz post them up or send them to me.

is there a kit for vl turbo ???

does anyone know if the icom JTG gear (tank and injectors only) are able to be purchased separately yet?

I wouldn't of thought so considering you need to be an accredited installer to put it in..
