Hey,
I like the sound of your turbo system. So did the oxygen sensor from the Landi replace the one used by the car's computer, or did you have two in there?
Did you install the venturi just before the intake plenum/ just after the intercooler?
I guess you never had it registered? Would be great if this system was legal, don't see why not

Hi guys, sorry I haven't got around to sorting thru my box of photos yet. The systems I suggested on this thread are for those who can't afford an injected system and are happy to forgo max performance to save some bucks.
For the turbo set-up I did it all myself. I used a secondhand Landi system from a 3.9 EA Fairmont. Even the tank fit! This system has the Landi control box which reads info from an O2 sensor which I had to install into the exhaust system. I did find the venturi from this system too restrictive and ended up running the turbo with no waste-gate at all to compensate. This car was amazing, awesome economy and could pull 200 easy.
On the supercharged 4AZGE car I used a huge secondhand venturi from a wrecker and the rest was pretty much new. I did some of the install but the garage that was certifying it did the most. They were really good and recommended which converter to run etc etc. This car was straight gas and had heaps of lowdown and midrange but ran out of legs at 160. Looking back maybe the converter was too small. It was also suprizingly thirsty for a small motor but it did demand to be driven hard.

So if you do lpg conversions, have you ever done a turbo vehicle? What's the total cost with the rebate? Would be great to have more info.
All turbo cars need at least a piggyback computer to alter timing on lpg. I've read it's very expensive.
I'm still keen to see tossers pics with some instructions on how he did it with the venturi setup. That way everyone can compare the pros and cons of each.

i do all lpg gas installs!! direct injection is the only way to do it! n u get $2000 gov rebate! ive gained kw readings on the dyno after installed on gas

im not 100% sure on what conponents im going to use theirs a guy that does gas injections near me and we chatted for a while when im ready to do the motor then we will talk about it indepth im gathering info off these posts to . . and extra info that people can tel me would be great

i have no experience at all with this topic and im just going on what ive heard from other people but ive heard that boosted cars run really well on lpg when set up correctly such as tosser has described

No I didn't modify the spark timing. The Cordia being turbo ran a knock sensor as standard which remains operational.

I will have to have a look. These projects were done over 10 years ago now so they will be print photos I will have to scan. There is nothing really to see with the Cordia set-up. The only way you can tell it is on gas is the converter which I tucked away neatly. I will see what pics I have.

Thanks guys, i think after digesting all the great info that gas injection is too expensive at this stage.
Tosser, your setup sounds really simple and quite a bit cheaper even if it may not be quite as efficient/powerful as the injection set ups..
I would love to see pics of your set up on the cordia - it would help me to set mine up.
Did you have to modify timing/spark with a piggyback computer?

If you don't want to go to all the expense of injected LPG with a computer you have other options.
I made my Cordia turbo run on gas(it would pull 210kph on gas comfortably) and I put a supercharged 4AGZE into a corolla on straight gas both using the same mixer I took from car to car.
The mixer is the venturi ring type I think it came out of a V8 or big 6. I got it from a wreckers. I just stuck it in the duct work immediately after the airfilter where the duct is largest and put a highflow converter on to feed it. It worked a charm. In both cases the more the supercharger or turbo 'sucked' didn't matter the correct mixture was being governed by the venturi. Simple and effective. I even ran an intercooler on the supercharged motor. I should dig up the old pics.
