Awwesome. Thanks Mick.
Thats exactly what I wanted to know.
Think im almost across all this craziness now.
VN K FRAME
VN S/RACK
VB/K V8 MANUAL PEDAL BOX
VN 304 & T5
VN CLUTCH FORK
VN LOOM & puter
VN P/STEER & AIR CON
VH RADIATOR
GET HOSES TO FIT AIR CON AND P/STEERING
VH TRIMATIC CROSSMEMBER DRILLED/SLOTTED OUT (forward or back?)

The car im looking at also has extractors already so Im hoping theyll fit..

Cheers again!

Think thats it so far.....

The car im looking at also has extractors already so Im hoping theyll fit..- the CAT clearance will be the biggest issue - nothing you can't fix easily at an exhaust shop (fit the extractors to the motor first though)

Awesome. Thanks for that Mick. Youve been an absolute legend with all this.

Plus your guide on BC site.

When its eventually done I'll drive to visit you and show you the VH!

Cheers.

VP had factory LPG using standard ECU with modded memcal. System was designed AFAIK to start on ULP and switch to LPG once warm. Was on V6 only but readily added to V8 memcal. You just have to run a bigger chip in a memcal, and double stack two programs with a switch to jump between the programs. One program has timing setup for fuel, the other for LPG. From memory when in LPG mode the ULP injectors are simply turned off. Very easily done.

Thanks guys.

Dave quey put me on to a bloke here in ballarat who specialises in performance gas conversions etc so Im hoping he'll be able to arrange that. One question youve raised though, is do I have to convert back to petrol as well now to start the car, or will i still be able to run straight gas?? Thus not bothering with the EFI tank and lines?

Why go to the bother of fitting an EFI engine, if your not going to use the EFI.

Thats exactly the point I was thinking of. It's a lot of stuffing around to put in an EFI engine when the injectors are going to be turned off 98% of the time.

If the 350's are no good in commodores then surely a nicely built 308 with a decent gas system will be just as reliable and a whole lot simpler? I've seen some real cracking LPG only cars that put out some pretty decent horsepower at relatively low build cost. There seem to be a lot of guys that spend a heap of money on an engine only to find out their cars too rusty or they don't have enough money to finish the build. Might be worth looking for one of these engines for sale. They generally sell for a lot less than the build cost.

Hi hainzy.

It does sound as though you have really put some thought in to this project. If it was my car, I would fit the EFI in its entire (stock) form & run a modern LPG injection system as we have discussed. The LPG injectors are separate units to the petrol injectors & require small nozzles to be fitted (drilled & tapped) near the existing EFI injectors. The electronics are quite simple because you've done most of the work by fitting the EFI system.

Taking your points one at a time:-

1. Put your HDT engine to one side & run the VN/VP 304 in unmodified form to keep it simple & to control costs.

2. Reliability. You can't get a much simpler or more reliable EFI set-up than the VN/VP V8 Delco. If you keep everything stock & fit a good quality sequential LPG system, it will be more reliable than the old V8 carby & mixer set-up.

3. Economy. This gets down the the size of your right foot. For starters, the EFI motor will be more economical than the old carby 308 (if you keep it stock). In my experience you will use around 20% more LPG than petrol by volume (for injected systems), but LPG is slightly less than half the price per litre. Your fuel bill will reduce by 40-50 %, will no loss of performance. As a matter of fact, if tuned correctly, you will get a slight gain because LPG has a higher octane rating than petrol (around 110), but remember this is about economy. not power.

4. A project of this type will give you a great deal of job satisfaction. You should be able to do most, if not all, of the work yourself.

5. This set-up is the perfect balance between old-school & modern technology & yet you won't even need an engineering inspection report for it.

Many people ask me what are the negatives of running LPG. I really think the only downside is having the tank in the boot (loss of luggage space). You already have this, so effectively there is no down-side to this project at all.

Getting a bit closer now...

Picked up the donor car yesterday.

FACTORY V8 5 SPEED WAGON Pretty uncommon far as I can tell. Out of rego and hasnt gone for a while so it coughed and spluttered beyond about 80 ks so needs a decent tune and the injectors cleaned out etc. far as I can tell... But thatll all happen in time.

Will gut it like a fish then sell of the carcass...

PICS

Thanks Jim. I was thinking about doing that. Thought it might be better to make sure its just a general tune up it needs rather than anything more sinister...

Also does anyone know what the general wiring plan of attack is? Looking at everything Im finding that the most daunting.. Do i just rip out the whole loom from both cars and try to get the VN one to fit the VH?

Awesome. Thanks Dr terry. I was hoping you would say something practical like that!

So I keep as much of the VN wiring in place as I can, and I guess mark where everything came from that i need to disconnect from the bay. Then do I also take the complete fuse box out from under the dash of both cars, and put the VN one where the VH one was?? is that the general gist??

Cheers.
