2JZGTE on LPG
|

Hi Guys,
I was wondering how you think a 2JZ-GTE would run on LPG?
Now I know that's a very open question, but lets assume that the conversion has been done correctly, and it's LPG only, not dual-fuel.
With the slightly higher octane of LPG, and the fact that LPG is already vapour surely it would run a little better than premium.
I'm just looking at buying a JZA80 at the moment, and there is a beautiful one I've got my eye on, but it's LPG 
Other thing I really don't like is it's auto, but the rest of the car is so good I may just be able to overlook that fact. From what I gather a Getrag 6 spd. conversion is probably going to cost me $4000 or so all up.

I'd say a 6sp manual conversion would cost more than $4000, even if you did it yourself. This would be because the gearbox's go for $3000, then you need to aquire all the other associated goodies, things add up...and fast.

Have you emailed the owner to find out if it's actually been converted to LPG? I find it hard to believe anyone would really do that... more likely the advertisement is incorrect.

Yes email to owner has been sent to confirm who, where and what was done for this LPG conversion, and to actually confirm it's been converted, coulda been a typo? I'm still at a loss as to why you'd do it

This thread makes me angry... 2JZ-GTE isn't an engine you have to save on fuel - it's a performance engine!

Ohhh....... Alan was right.. It was only a matter of time before I got myself into this thread.
However, as much of a supporter of LPG as I am (see below) I really and truely CANNOT see the value in converting what is otherwise a quick, powerful STOCK car to LPG? To what end? It's not like you need a fuel system, it's already got one. It's not like you need fuel efficiency, I mean, take it from me. Wind the boost up and you'll go through LPG quicker than petrol.

Sorry, further to that, it does look like the goose that put the ad in selected LPG rather than Petrol from the drop down list for Fuel type. That's what I'd say.
Does not look like the kind of car an owner woudl want to save fuel on. I mean look at the amount of weight he's added to the outside of it.

Those days are long gone. Most LPG is 98RON these days.

If you look at the product data sheets for all the different oil companies as norbie said LPG goes from 98(min) to 100(max). Anyhow this thread can die quietly now as the general concensus is 2JZ-GTE on LPG is bad, so I shan't buy that particular car

sorry but LPG has a terrible name due to most of the pathetic dual fuel conversions over the years...backfiring, blowing up airboxes, air fuel meters the list goes on and on.
my 4AGE 100kw motor ran great on LPG - no issues - made plenty of power and was good to drive. that said it was not a cheap conversion - gas research gear is not cheap.
as its been said before a 2JZGTE conversion in lets say a JZA80 is pretty pointless ; the car already has a good fuel system in place - why would you bother?
BUT if you were doing a conversion to another car perhaps then LPG would make a good alternative to crappy PULP.
the vapour injection systems they are putting now on the new falcons and consumerdores are very good and put most of the dual fuel ideas to rest (like they should have been a long time ago)
its a good alternative for a performance modification.

I am serious about building some sort of crazy high horsepower motor for another Z20 or maybe a Z10 soarer and the workshop sonsoring my car (ADCO Race Engineering) is very keen to use it as a test mule for a new Injected LPG System he is devising, cant wait to start on it, now I just need some crazy motor to work with, was thinking 1UZ, but maybe a Twin Turbo One

yer something different has also crossed my mind a few times, but I do want a fairly light motor as it will still be used as a drift car, one of those 2.7 litre hilux motors or maybe a 4.5 litre cruiser motor (read: MS-75)

you'll make more power on petrol, even with the cooling benefits.
LPG takes up a huge amount of space in the intake runners compared to petrol. With EFI fuel atomization isn't a problem anyway. LPG is smoother since it burns slower, but thats about it.
GRA's figures are true but manipulated in a way to convince the average joe that you can make more power on gas.
Their test mule is first dynoed with petrol
Then with a gas throttle body. Gas power is lower.
After they fit a special "GAS CAM" they dyno it on petrol
again, then on gas -- and wow!! the gas figure is higher...
I wonder what a "petrol grind" cam would do?
LPG is good cause it's cheap, if you can't afford petrol, convert to lpg!! Many a car I have beaten while on LPG, it's so sweet when you know it only cost you 10c instead of $1 for a quick run! (265 turbo is on lpg)

I agre, it does look pretty.
Plus I am thinking that having a LPG tank in the hatch would be great, you could paint it blue and put a big NOS sticker on it

Ahh yea i'm hearing ya!! i'm thinking UZZ10 twin turbo drift beast as next project 
sorry to slap this poor decrepid thread back to life but i love LPG, it's so responsive to tuning and more and isn't restricted to octane and compression issues like petrol, think chunky cams and mad boost My tow car falcon is on it and i have owned plenty of other fords and chryslers on it, petrol systems are the restricting factor in my opinion, ok i'll go now....

even Ferrari & Lamborghini aren't running LPG. Not Even Rolls Royce, but WHY would people do it to these engines to a stock car?
