give me some dimensions my mate has a chart so i can tell you the type of tanks you wanna look for...although i imagine if a commodore tank fits in a TA22 then it will fit in a crownie...

Hi Crown Crazy,
I've currently got a GasResearch LPG-only setup in my 3T-GTE powered TA-22...

It’s an 80 useable litre APA tank, Modified B2 converter, Highflow lockoffs, GRA throttle body, etc... & works fine with my current configuration putting out around 150kw at the wheels.

Given that it no longer is a street car (& that was the main reason why I installed LPG in the first place, as it was the only way I could get it past an emissions test in SA 12 years ago )... I'm looking at going back to petrol soon & would be willing to get rid of this working setup for a fair price.

I don't get on the forums much these days, but whoever / where ever you end up getting it from, send me a pm if you need a few tips if you get stuck with tuning it too... I can also recommend both Michael (mrshin) & stradlater who have both had experience in this area before.

I was looking to go down the path of liquid LPG injection... but after some more research, have decided to keep it "simple" for now.
Cheers,
3T-GTE

liquid/vapour injection is still awefully expensive. although it is significantly better than the carby type/venturi type LPG systems, it would be cheaper to go aftermarket motec fuel injection in some cases.

the holden gen3 vapour injection setups are ~4.5k installed. they doe comply with adr 37 though. no power loss or loss of economy either.

For those who haven't already read it, its probably also worthwhile pointing to this thread... its a long read, but useful.

As for liquid gas injection, I'm keenly watching out for these guys to get something affordable to market. http://www.lpgli.com/features.html

Did someone say LPG???

[turns green and hulk like] OH no, here it comes again!!!!! [/hulk]

Well, now that you asked.......

:-)

[Grega]

all we need now is shinny....

[stradlater]

With his and my powers combined ..... You'll NEVER hear the end of it!!

[mrshin]

Oh, I'm here...

[Grega]

bout time you rolled up

now back on topic ; crown LPG conversion - injected or gas research?

[mrshin]

I think it goes without saying that I'd be choosing injection any day...

[stradlater]

I haven't got injectors or used them, so I really can't comment, but I'd probably go injectors if I did mine again.

[Grega]

even with the purported cost on the inected setups guys? over the GRA stuff?
my only issue is really that the GRA stuff whilst can be tuned "well" it can't be tuned completely for everything (like the injection can)
but, is the injection worth the extra spend?

[stradlater]

that's the exact question isn't it mate.

The GRA stuff can be tuned reasonably well, but not to the lengths an injector can..

the other thing is, I have heard that gas injectors don't cut it as far as performance goes just yet.

Hell, I'm plugging up my injectors holes at the moment anyway..

BTW, anyone GOT any injector hole plugs i could use?

[Grega]

strad, i used small imperial welch plugs to plug up the injector bosses in the 4AG.
them and a bit of stag never moved.
