100 Series 4.5ltr LPG Conversion

Sorry Gerhardp1 . I will come down hard on you for this miss informing post.

Gas injection is probably the best solution t economy om 4x4 today. In the hundred series , you will gain around 5 kw in power and only use 2 max 3 litres per hundred more in gas . @ 44 cents , you do the math. I paid for my system in 6 months . ( yes I do masive kms )

OK, I'll take a partial caning on the economy front, but I'll defend my comments re

The reduced load capacity - the mathS is simple - if your gas tanks and associated stuff weighs 200kg, your load carrying capacity decreases by 200kg. If you have a bullbar and rear tyre carrier/bar, you can't pack much gear for your travels .

You have to do a lot of ks to recoup the cost and you never regain the carrying capacity.

in a injection kit , the injectors and ecu weigh 0 . The gas tanks is the only weight increase approx 50 kg , bullbars etc... are irrrelevant to this discutiion as they have nothing to do with the fact of your car been on gas.

There are also other benefits EG. Longer fuel range . And another system to run on if you loose a fuel pump.

Thanks mate for you help. I have booked car into get the injection system doen next week.

All the feedback is pretty supportive and I am looking forward to (hopefully) cutting fuel costs by about half all up - hopefully!

Hey chardthechippy

Thanks for the feedback

Deal is done and I get the injection fitted next week.

Many thanks

Since you mentioned that LP1 fits cheaper equipment that what you do . Could you please inform us on what kit you fit ? and also explain to us , what makes your kit more expensive .

Regards Eric

G'day Rock Crawler,
The equipment we use is the OMVL Under bonnet gear with AEB Electronics. The kit is distributed through Sprint Gas.
Basically mate the equipment we've chosen to use in our conversions has been chosen for it's quality. Whether it be the OMVL Converter, Reliable (internal circuits & galaries don't block up or wear out), Adjustable (you don't need to pull the thing apart to adjust your mixtures), Efficient (sensitivity adjustment enables fine tuning of acceleration off idle), Positive Pressure (actively feeding the engine), capable of fueling an 8Ltr engine ( & then you can boost them), Plus they're repairable - you can get overhaul kits for them when the diaphragms get a bit stiff with age & they'll be as good as new (unlike others).
The electronics in the system is not only thorough but its also reliable & comes with extra functions like power economy functions, Petrol start auto change over to lpg (keeping fuel system lubricated, injector rail flushed of sedimentation, servicable/working, Prevents stale fuel), Emergency Gas Only start up option incase your petrol system lets you down, Programble operating parameters, Push button operation, neat in-dash mount.
Even the upper cylinder lubricant kit has been chosen because it is the best, most user friendly & reliable kit. Easy to install, durable, reliable & easy to use.
The proof is in the pudding. We of course see alot of vehicles for repairs so you get to know the usual traits of the particular equipment.
We're fussy with what we use in our conversions. We have a good reputation & we want it to stay that way so we fit good quality equipment & that way our clients are out there saying only good things about us.

Please correct me if I am wrong in the following , but isn't the OMVL Spring gas systems , one of the first on the market .

Also , dont all injection kits start on petrol / have a set temp cut in , and low pressure cut out ?

I have seen the OMVL in action , it's does well , but seams not to like BA'S . I also found it to switch to petrol first out of most kits I have tried on V8's . Usually 4500 to 5000 rpm.

I found the performance on the Prinz kit on my cruiser to be better than the OMVL . But must add that I dont like the 3 group injector set up. As you can't get the injectors as close to the manifold as I would like. Also , they can be noisy at times , but seam to out last the injectors provided by sprint.

I experimented with the Voltan kit for a while . Concept was fantastic , but I could not get any consistency with the kit , also found the teck department useless .

Would be interested to get your view on the above . Also please note that I dont own a gas shop , I just get a lot of cars fitted with gas for work. i also spend hours on end on the Dyno on saturday mornings playing with the ecu settings .

I am looking at another overseas kit at the min , that seams to have great potential , as long as it dosnt turn out to be a Voltran story lol

Hi Rock Crawler, Do you have an opinion of the LandiRenzo Sequential Gas Injection kit fitted by LPGAS1? Did you research them prior to fitting the Prinz and what were the advantages/disadvantages of each?
Thanks, Bruce

Are they still fitting that kit ? I thought they would have moved on . One of the first kits , very large convertor from memory , but you dont hear to many issues either . the later kits had better power figures but are still tempremental.

Well I had the kit fitted on the 16-02-2007 at the inverter seems quite small. It's a square shaped unit about 12cms square. The injectors do make a little noise but the guys advised me that it is the most reliable on the market. All the ECU is the latest generation learning unit which adjusts according to individuals driving styles. Do the injectors in your vehicle make a noise? What sort of consumption figures are you getting? Thanks, Bruce

The injectors in mine are not very noisy. But the Prinz kit isnt known for its quiet injectors lol The injectors can be very noisy.

I am sure that your kit has been upgraded since I last saw it. The best ECU on the market at the min , is suppose to be the new generation piggy back system. This system can also change duration time in petrol injectors like say a MoTec system. The the gas system copies the same curve. Now in theory , this is the best possible senario . I get my hands on one in around 2 weeks to play with, so i really looking forward to it.

Consumption on my cruiser is 22.8 city driving . I have not done enough hwy k's to give you figures ( obviously not enough holidays lol ) . I have tuned my cruiser for max power not economy also , giving me around 8 kw more power on gas than petrol. Please also not tha i run 35" tyres and a ton of electonics and gear

I hope this help, what yours returning now ?

G'day Rock Crawler,
Not exactly sure how many other kits were out when OMVL came out with their injection kit. Thought we were talking about the venturi system.
On the venturi systems, the AEB Electronics has the option to start on petrol & change over automatically but you can also do a straight lpg start up with the push of a button if your petrol system lets you down. The Landi & the Impco don't do that. The 295 also has a power economy function built in which sets it apart from the others.
As far as i know all injection kits start on Petrol & change automatically.
Can't say we've had any drama's doing BA's. Bit of a let down the size of the cylinder that's spec'd for them but i thought they come up a decent fit.
Havn't heard of the Prinz or Voltan kits. Googled them but came up empty. Interested in learning more about them. Especially if you've found them to be ok.

We've had good results from our vapour injection stuff.

You will find most kits do a emergency start on either fuel by holding down the change over button. Dont waist your time with the Votran kit , god knows I waisted plenty lol. Prinz kit is great. Looking forward to testing the new kit that out that I described above , Ill post what i find with it. Sorry i cant give it's name yet.

Many thanks for your feedback - the cruiser is booked in for late next week to have gas injection fitted - this give sme a little time to de-bug the gas system before I take-off to Cuttaburra Bore in early June.

Many thanks for you advice earlier today. Ihave booked the Landcruiser into LPG1 for late next week as I am really only getting positive feedback re LPG conversion.

I will give you a call in next day or so to have a look at your install if OK.

Regards

Ken (aka kktdw)

G'day Ken,

Not a prob! Give me a buzz and come over. I think you'll be impressed by how neat an install it is and the how little changes in driveability when in gas or petrol mode. Even the boys at Toyota were impressed at my last service. A truly professional outfit, the boys at LPGAS1

Regards,

Bruce

Thanks for the info and feedback. The Cruiser is booked for the gas injection systems fitout next week and I hope I can get my consumption down to what you get. If so, I will be a happy chappy !!

have you done other engine mods to improve consumption??

regards

Ken (aka kktdw)

Nup and she has 260,000km on it. The gas has only been on since dec when i bought it. The only thing that I do differently is use a V8 air filter to get better air flow, but get it B4 you get the gas on so they can set the mixture to the bigger filter.

260,000klms and going strong - why would anyone want anything other than a 'Cruiser?

Ken

Mate I only use GTX3 the same as in my old sahara and 80 series dual cab (both LPG) barely uses any over 10,000km and I think it is cheaper than LPG oil.
TB

Yeah sounds a bit that way, How many km.
Maybe penrite for older engins is the go with yours
TB

Hi mate,
It's an RV. I didn't want airbags or ABS
IMPCO system easy to service and they don't go off tune.
