diesel on gas (impco set-up)

[full-boost]

hi guys, looking at putting diesel on gas on our 89 GQ 4.2 turbo. went to LPGAS1 and they do an IMPCO set-up. anyone read or know much about these set-ups? i had an IMPCO set-up on a previous vehicle, but that was petrol/gas not diesel. any advice.....
thanks in advance guys.

P.S. it injects the gas after the turbo

I think you'll find that the setup on your old petrol/gas setup and a turbo diesel setup might as well be compared to something like "chalk and cheese". The new "diesel/gas" setups are all electronically controlled/injected, whereas the older setups run off vacuum. And also bringing a turbo into the equasion pretty much rules out the older style setups (except for GasResearch etc). I could be wrong, but i'm 99.8% sure you'd be up for one of the newer fandangled setups. Do a search for diesel/gas (try a few variations!!) and you'll find HEAPS of reports/pricing/things to watch for. Good luck!

I've fitted an Eco-Shot system to my Hilux, it's a good system it runs a vapour tank so there is no need for a converter or to tap into heater hoses it takes up bugger all room under the bonnet and is really easy to tune. Known as Eco-Shot in Australia and Power-Shot in the USA. It gave me an extra 15 kW and 100NM at the wheels. 45lt gas lasts almost 3 tanks of diesel and give me an extra 100kM on average per tank of diesel

I have been researching this as well and would suggest you look at Hunter Gas technologies Sequent II system. From what I have found it is the only system that uses vapour injection post turbo and intercooler (helps with cooling the intake charge) and also provides gas right from idle. This results in providing better economy (uses gas at idle) and provides the power benefit right from the bottom end. Some of the other systems use a fogging system, some only kick in with boost and increase with boost. Most systems use a stepper motor to increase the delivery (ie: gas volume increases in 'steps' not in continuously variable amount). The Sequent II system gets feedback from multiple sensors and calculates the volume of gas 10 times (or something like that) per second. That equals perfect volume, no retuning, and more efficient use of gas. Check it out, it would be my pick.
