Hi ,

Has anybody heard of a gas conversion of a Z32 tt ????

 

There is a gas conversion specialist just out side Swansea ,which i called into and asked.

 

He told me it could be done at a price of £1500+ . He said he's never done a 300 B4 but done a few Supras twin T's .

 

IS it safe ? , Does it shorten Engine life/Turbos , And most of all

does it affect performance .

 

Any Help/Advice would be great Thanks

 

Darren

i think it is a higher octane rating ... 105 or something like that ... but u car will not be as rapid ....... where the hell r they going to put all the crap for it ? theres just about enough room for a rizzla paper under there ?

I agree Scott and not only the front ,Look at the back. The Gas tank in the boot of the z !! At least it will cut down the wife shopping !!!!!! :-)

When I win the pools / lotto / premium bond, I'm going to try this. The only bloke I know who did this did it to his Cherokee Jeep so not exactly a good comparison.

 

He says it makes his car about 10% down on power but the fuel is half the price so he doesn't give a ****.

 

Just think what you could do with the standard exhaust / induction / chip upgrade twinned with the LPG. Yes you'd end up with no boot but could probably still do 280 or so hp, look cool, drive fast and hug trees!

 

If anyone really is going to do this, keep the records - you'd probably get interest from club mags or possibly even mainstream ones.

If you want economy buy a diseasel Fiesta!

 

LPG conversion on a thumping great V8 Rangy is one thing but a Zed, what is the point in buying a performance can then detuning it with LPG, and yes LPG will give you a drop in power. What about the cost savings? You just wait for the Chancellor to whack duty. Stealth Tax No. 234567898765!

cant see the point, because if you want a green car then this is clearly the wrong car for it, Turbo charged cars are designed to give you a certain driving experience ect, and well whats the point if you lose that?

 

By an NA if you want the car just for looks.

Dont forget you can still drive on petrol with a flick of a switch , So you get the best of both worlds so cant be bad ...

I was thinking of having my Lexus LS400 done, spoke to a few people, turns out some just stich a pipe in the air filter (almost, I joke not) and some systems are ECU controled with mulitpoint gas injection. These are supposed to be really good when set up correctly, and for £1500 I guess thats what you would get.

A lot of cowboys though.

I have looked heavily into gas conversions for a 200sx. Yes there is a slight loss of performance but you can switch over whilst driving with no noticeable change so if you want the performance back you can do that. Your turbos and engine will last longer and you can service it less frequently as the oil doesn't get as contaminated when using gas.

As your using turbos you will have to get a multipoint gas injection system not a simple inline jobby. This should cost around £600 +Vat for the kit but you may need to find someone to fit it. If you do look out for certifications or if not just make sure they fit the pressure release valve as many cowboys don't bother to save the hasstle but the gas can then explode in the event of a crash. So long as this is fitted gas is just as safe as petrol if not safer as it is all closed off and unless heated and vapourised is not as ignitable as petrol. I now have a 300zx n/a but am soon selling it to get another 300tt and i shall without a doubt convert that. If you change the air filters and get an induction kit there should be enough room to fit the gas solenoids and vapourisers there.

apparently ... petrol cools the piston crown !!! especially on high tuned motors ?????

 

i may be wrong but would lpg not be a bad idea with a twin turbo ... never mind a tuned 1 as u try to reclaim the lost performance ??

 

scottie :)

meant to say ... would be a bad idea ....

 

DOH :confused: :confused:

good point - but small disadvantage is extra weight of another tank :(

Easy way to reduce performance - leave the handbrake on :D Similar fuel savings can be achieved by using less throttle so I heard but atm I'm getting 22.3mpg even when I'm caining it everywhere so :p

when gas goes from liquid form to vapour doesnt it chill something serious just like a refridgerant. Maybe it could have some charge cooling effect better than petrol?

 

Does it get injected somewheres near the fuel injectors or is it dumped in further up the manifold?

Thats a great idea but have you considered how many miles you will have to do to justify the 1500 quid cost, and while your trying to do your slightly slower extra miles remember the govt only promised to freeze tax on gas till 04!, and they have an expensive war to pay for, doesnt take agenius does it ?. Why not buy a cheap diesel 2nd car, does three times the mpg and keep the zx for the reason it was intended, or alternatively if you cant afford it why not sell it ?? just my two penneth

Wouldnt catch me having a chicken shit conversion on mine, Like Duff said I reckon a niceley driven petol zed would give very similar mpg to a gas one, but without the worry your going to explode if your cigarette blows back through the window and lands on the rear shelf!!!

BK9!RS Said "Wouldnt catch me having a chicken shit conversion on mine, Like Duff said I reckon a niceley driven petol zed would give very similar mpg to a gas one, but without the worry your going to explode if your cigarette blows back through the window and lands on the rear shelf"

 

A niceley driven Z could not get anywhere near the cost per mile of one running on a properly installed gas conversion, Not in a million years, and when was the last time you heard of a car blowing up? Gas or petrol.

 

OK, it would lose a bit of performance but alot of you guys are missing his point. he can switch it to petrol when wants all the power, and who can use that much power very often?

Yeah, at least 100! :D

People have said that you lose about 10% of your power when running of gas, but you also get 10-15% less fuel effiency. So instead of getting 20mpg you will be getting 17-16. Plus the extra weight of a gas tank that is large enough to actually held enough gas to get anywhere in a Z.

 

The Z needs a large petrol tank to hold enough to actually get some where. Think of a 60-70 litre gas tank in your car and how much that would weigh. It would probably knock your MPG down even further.

 

 

Stuart

If the weight, less efficency idea held any water then why would anyone fit a gas conversion?

Fact is they are less efficent, and there is slightly more weight, but the cost per litre makes up for a great deal of this, hence the market for gas conversions.

Of course the many thousands who have fitted these kits might all be wrong.

There are those on this forum who dont like the idea of a gas conversion, fair enough, but to come out with unrealistic arguments just to try and justify ones position is not helpfull to the person who wanted some help. Such as "Chicken Shit conversion" Maybe he is looking at the best conversion money can buy, hardly chicken shit then is it?

 

No offence, just trying to justify my point of view.

I don't see a problem with it other than the space taken up by a new tank and the sporadic placement of refill centres.

I thought he meant "chicken shit" as in methane not as in crap. If you see what I mean :D :D

 

But LPG isn't methane so he's wrong anyway (pedant-in-training).

 

Yes there are performance downsides and yes you lose space because of the extra tank. And probably add extra weight so Nelson wouldn't be best pleased.

 

Yes you keep a petrol tank and a switch so you can go from one to another - hence LPG stations being rare is not a problem. You just have to fill up with expensive smelly carcinogenic fuel. (calm down calm down only joking).

 

I don't know where the LPG actually does evaporate (i.e. go from liquid to gaseous) so can't comment on the piston cooling effect.

 

Buuuut from the info on this site, there is little or no problem in getting, say a 15% increase in bhp. Exhaust, induction, ECU (I believe - haven't done it myself). Then (in theory) do an LPG conversion, lose 10% and you've still got a better-than-stock clean-burn, hug-as-many-trees-as-you-like, performance car which runs on a cheap fuel.

 

If you're an ex-hippy like me, that's not a bad idea! :D We don't all want to run Honda hybrids, you know..... ;)

Oh shit , What have i done , Opened a can of worms or what !!

 

Thanks for advice guys for the pro's and cons .....

 

I probably will do a conversion as i do 800 miles a week in the z (let you know how i get on) And yes it's a multi point top notch system hence £1500 and not a £750 so called chicken shit conversion (Or did you mean in gas terms).

 

And for selling my z if i cant afford it ... (Ouch) I can afford to run it but i hate throwing money away if there is a better option , Thats why i have so much money !! lol

 

Cheers for the advice

Hey Gio,,, not sure common sense is what people want on this thread. LOL

OK matey - I'll get fuelled up on the vino collapso and see what I can come up with :D lol

 

Darren - if you stick LPG Conversion performance into Google, you get loads of links - here's the FAQs from Calor

So........ did anyone do a conversion on a z ??
