ECU, new unused vapouriser, the old one, 6 decent injectors, plenum straws, all looms, 70l tank, vent hoses, cut injector cables, manual, rubber hoses.
Requires, 6mm, 8mm LPG pipe, a few olives.
There are pictures on this site if you search for them.

You will need to be able to solder, and fit the pipework, also fit the coolant hoses for the vapouriser.

I can solder and have done a bit of pipework in the past!
Would this be suitable for Zirks 3.2 V6 estate?
This is only a thought.....

I think it would definately up to the smaller V6s but the 3.2 will be near its upper limit but then it is cheap!

Um, right, yeah :-[
Haven't really done any research on LPG, I don't suppose you could explain that in laymans terms why the 3.2 might be at the limit? If you have the time of course.

Don't quote me on this, but I believe the system is unable to supply enough gas (pressure) quick enough to satisfy the 3.2's.
I thought about this myself, but after reading some posts by Martin in the past and other sites, this will struggle.
HTH's :y

If its a single hole tank, it may not be possible to deliver the gas to the engine fast enough (most are borderling on 3.0l, although there are some better, higher flowing valves out there (though I believe Martin Imber's is too old for a high flow multivalve).
The vapouriser also has a maximum limit, usually rated in BHP, but you need to give yourself some headroom, as the manufacturers are a bit optimistic it seems.
Lastly, the injectors need to be able to get enough gas in a cylinder in a cycle.
If any of these are lacking, at best you'll get lagging, low power, switching back to petrol etc. At worse, if it runs lean, it will need a new engine pretty quickly.
-
Martin Imber - as you know, the tanks are certified for 10yrs from manufacture, after which time they need recertification (which in the sake of tanks is usually cheaper to simply replace the tank). It worth saying when the tank was manufactured, as that must be getting close on yours (IIRC, you removed this from your old car and installed into your now bent one?)

It will have a date stamp on the plate that has the serial number on :)

Are straws less than ideal for gas delivery :-\

Yes. Its a bodge, frankly. Sorry. All things being relative and all, as piggy back systems are a bit of a bodge themselves, as we all have. But straws are a bit Micky, to say the least. There's a risk of air leaks and the straws snapping off. The lpg should be injected as close to the petrol injectors as possible.
Having said that, I've driven a couple of recently fitted Brc systems with straws tapped into the top of the plenum and they drove ok.

They work fine but can make plenum removal awkwards.
If I was doing it again it would be nozzles in the inlet manifold, but straws work fine

Piggy back?
They work, never heard of one snapping off and the injection point is not far from the gas injector, 20mm or so upstream.
Main advantage is it saves removing the inlet manifold.

Precisely. Rather than remove the plenum and then the inlet to be drilled without swarf through the engine. Its a short cut by half arsed lpg fitters. Having said that its only aluminum swarf.

Although there's nothing to prevent it being fitted properly on the car of its new home.

Actually it cannot be drilled in position as you need to remove the plenum to fit the cut injector cables, then you drill out of the plenum rather from the top.
Not the best solution but not a bad solution.

Oh, so what's the advantage again?
