Thread: P38A 4.6 & LPG conversion info

My P38 had a gas conversion (vapour) done at Ezygas in Melbourne.

It is a SPRINT system if that means anything.

It works really well and I have never had a problem with it.

Dave,

Is the Ezygas Sprint system a 'mixer' or 'vapour injection' type ? ( sorry ..just read your reply again and you state it is a 'vapour' system...that'll teach me to read before engaging brain and writing !)

$$$$ ????

Any performance hit ?

From my research so far will probably go down the 'vapour injection' route...more $$$..but seem to be better with reliability, performance and economy over the 'mixer' systems...hearing horror stories about backfires using 'mixer' types !..

cheers,
Richard

Sorry probably my mistake actually. It is a mixer type, not direct injection.

I bought the car with the system already installed but it was still quite new. I had heard (completely unconfirmed rumour) that the direct injection cannot be fitted to the GEMS motor.

The performance is surprisingly good, and I find it actually runs a lot smoother on gas than on petrol.

The real grin from ear to ear happens at the servo when you fill up for $30 instead of $100+. Sure it doesn't go as far but you're still way out in front.

Oh and .....(grabs hold of something made entirely of wood) ......I have never had a backfire or a miss from the system.

It automatically starts the car on petrol and transfers to Gas when it is firing.

I was told it cost the guy around 4K.

Hi Richard

Where are you ? I am also getting quotes together in Perth. Sprintgas say that the P38A, 1999 4.6HSE is not good for the direct injection system. Their cost is approx $2600 completely fitted. Rebate of $1750. Others in Perth have told me that this model DOES NEED the injection method. Very confused???

Anyhow, looks like I shall go this route as they have some fancy EPROM that compensates for the injection. Pity they only have a 42L donut tank capacity. Autogas Perth have a 72L donut tank but hey charge $5600 and use the direct injection.

regards
John

Just tell em to get the bigger tank.

Deano

How'd you go John? I'm looking convert my 2001, but definitely want the larger tank.

Have you sourced a wheel carrier as a result of the conversion yet?

Impco is fine on the early P38 (Sagem injection) but be prepared for a fair loss of low down grunt. Gas injection is far, far better but $1.5K or more on top. Always get new leads and suitable LPG plugs fitted at the time of the conversion.

Hanging the spare tyre underneath is not practical with a full size wheel, lose your air suspension pressure and you will lose the wheel. I don't know if anyone can confirm, but the stud pattern on a P38 looks suspiciously like a Commodore, you might get a suitable space saver wheel there.

I posted some "LPG pics" earlier last year for you to look at.
