hi,
I have been talking to Heath quickly about LH's and LX's. He has told me about the main differences between the two, in the form of the radial tuned suspension.

What is the difference between both suspension setups?

And i was looking to replace the suspension when i find a torana. So can any differences between the two be eliminated if i do this?

Any other info on the differences between the two would be appreciated.

thanks ryan

Hello, if you get an LX get a build that was built before July 1/76, then you don't have to comply with ADR27, Just to give you an idea:

I have not yet learnt about the difference's, so I will sit back and read

P.S - Do any torana's have indicator stalks etc?

Yea, Will that design rule effect me if im goin to put a new ecotec engine in, which will be fitted with all the new exhaust gear?

You will have to comply with all the emissions regulations for the donor car.

What ever year that is.

The simple answer to your question is NO, the model you pick will still need to comply with above.

If you run the new engine on straight gas it will make emissions life easier.

ok thanks.

But i think if i go with LPG i will lose to much power and will cost a fair bit to convert over.

Or are u meaning straight unleaded

If you get a real nice gas set up the loss of power would be tiny to tini to notice but a set up like this would be big dollars so yeah its a bummer.

It is always a misconception that gas cars loose power.

How many of us put our hands up and state we will only run preimum unleaded because of teh extra octane??? So why not run the gas? it too is a high octane fuel (infact higher than most premiums) but this is where the similarities stop.

Gas burns slower. so to tunr teh car properly your dizzy needs recurving and way more advance. Starting becomes a little longer as the gas(left overnight) needs to be feed into the cylinders again. if car is hot you should notice no difference. You can run a higher compression ratio and gas does nto detonate as easily as fuel. The gas runs colder through the intake but has a hotter burn (hence why better valve seats are required (as with fuel gas does not have a lube so cannot assist with cooling teh valve seats etc). You need to increase the temperature range of the spark plugs also as fouling will occur. All up gas is an awesome fuel, and if tuned for gas will actually make more power than teh same motor tuned for fuel. DO NOT go duel fuel, as with teh different burn characteristics and timing etc etc you will have a hlafway house on BOTH fuels. Tune for striaght gas or straight fuel.

The new Gen 4 gas systems actually use a special gas injector and thus are still "fuel injected". The standard computer can even run teh new injectors and run teh car without issues at all. Infact more power and a better torque curve does result in the conversion. These systems are availible now but you need to find a specialist to do teh conversion as most gas places will not use this setup. Thsi system is expensive, but with gas being kinder on teh motor and solving a few issues you have with fuel then it is a very good investment.

I am lookign at this system for my EH, and will be approx $3500. But this includes two (not one) but 2 80L gas tanks. plus install and other components (ie injectors etc etc. Teh tanks on there own cost about $920 each. (these are not normal gas tank "tubes" as I am mounting the tanks specially. So tehre is some saving there. not to mention that you will save on teh fuel bill. Keep in mind that gas does get used a little quicker (ie you will use more gas than the fuel) but look at it this way...

149 c per litre. = approx $79 per fill and drives you 400 km.(maybe)
48c per litre (with a 160L tanks like mine) = approx $76 and will travel 1100km.(ie melbourne to Sydney one tank)
if above example is for a 80L tank (60 usable) then =approx $29 and will travel 380km-500km. Does it really make sense to try and uild a motor for fuel when gas is just so nice and availible now?

Yea i see all the benefits for a converion to gas especially how high the bloody fuel prices are now days. The only thing is i don't think i will be able to offord the conversion, but on the other hand in the lond run it may be much more cheaper. Ill definatly look into it when i get the car.

Side tracked here..lol

Could anyone outline the differences between the LH ans Lx's.?
also which LX's has RTS fitted?
and wat is the difference them.

thanks ryan

Hi Guys.

Liam. W, said,

"Hello, if you get an LX get a build that was built before July 1/76, then you don't have to comply with ADR27, Just to give you an idea:"

This is not quite correct. All Holdens from '73 to June '76 must comply with ADR27.
From July '76 onwards it is ADR27A they have to meet, which on carburettored cars can be a bit fiddly.

If you're going to fit a Ecotec V6, there is virtually no anti-pollution gear to worry about, it's all done by the ECU. If you fit one of these motors, about the only things you need are the carbon canister (LXs already have one), a catalytic converter (should come with the donor car) & a fuel filler restrictor (usually need to be made up). There is no anti-pollution gear, as such, on the motor.

....incorrect.
Gas engines will be fine on plugs designed for petrol, theyll be as clean as......
What is often done is to run a cooler plug as there is there is less chance of fouling on lpg. The reason to run a cooler plug as possible is to stop possible predetenonation of the charge mix from an overhot electrode in performance applications and this should be done in an lpg motor too if its going to see high speed/load use.
The plugs will also be much cleaner(you need frighteningly rich mixtures to foul one) in short travel trips as they never need to run higher fuel/air mixtures when cold.
Re the suspension, rts was fitted to LX late in the run, look for the badge and I think its identifiable by sway bars at both ends.....can someone confirm?

If you're going to go to the effort of replacing the entire front crossmember, I wouldn't bother with an LX RTS front end over an LX or LH non RTS front end. Go straight for a UC one, including steering rack. The differences in the RTS vs non RTS LX front ends are very minor, especially as springs and shockers are likely to have been changed at some point in the car's life.
