200 Series Cruiser LPG Conversions

Hi, since the 200series comes in both petrol and diesel models, are you talking about a petrol/gas injection conversion or a Diesel/gas injection system?
If you are talking petrol/gas conv then read on...
i have the gas injection system fitted to my 80 series petrol. Mine is an Apollo system, installed by Premier Auto Center in Mt Druitt, Sydney (02) 98321650. They are one of the big players in gas conversions and would know and recommend a good installer in Melbourne.
Mine has 6 electronically controlled gas injectors wired into the factory engine computer/ECU.
Running costs have literally halved since it only uses a little more gas than petrol, but gas being less than half price makes it pretty well spot on half the running cost.
Figures for mine are around 350-400kms from 80L (90L tank) at 70c/L, so costs about $15/100kms with city/hwy driving.
Gas injection is said to be 20% more efficient than the old carb type, and thats when the carb/mixer is tuned spot on... most need regular re-tuning and so arent fully efficient most of the time unlike injection which never needs tuning. Also injection doesnt backfire so you wont risk any engine damage.
Another good thing about gas injection is it's fully automatic and computer controlled. At 40degC coolant temp (had mine changed to 50degC via the installer's laptop), it switches over to gas without you even knowing (apart from an amber light turning green). No loss in power at all and super smooth.
Best thing i ever did to my cruiser and i'd highly recommend it.
Pretty costly though, my 6cyl was $4,600 and a mate's 100 series V8 was $4,990, less the 2 grand govt rebate which is still on offer.
One thing to ask for is the long torpedo like gas tanks which run along the inside of your chassis rails. I know you can get them to suit 6cyl 100 series but not V8s as they run a lexus chassis. Not sure about 200s but they are worth asking about, so you can keep both petrol tanks.
Hope this is relevant and helps.
If yours is diesel, do a search as there has been alot of talk over gas injected diesels and their benefits.
Cheers.

Nunnawading Toyota had a demo Petrol 200 that they converted to gas and put a rear bar on about 4 months ago. I saw it the other day on the road but I assume they have sold it by now.
They might know what works well.
If you get one with gas take a look at the rear wheel carrier from Kaymar, very schmick.
