Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
The injectors on this car are very quiet, completely noiseless in fact. Because they aren't plugged in. The car is dedicated LPG, doesn't even have a petrol tank.
Ticking is less frequent after a couple of days now but it is still there and it misses when it ticks. A new set of lifters and a timing chain are on there way and we are thinking of chucking in a stage two Crow cam.
Also researching LPG tunes. There is a seller on Ebay that will do an LPG memcal for $139.....Can foamy do LPG tunes?
I might do that first. It does roughly 300kms a day so I'll chuck a bottle of lifter free in it tonight and change the oil tomorrow night.
Not THAT loud. I have noisy injectors, they are not that loud.
Do your lifters I say, and throw in a little cam, whatever you can find. a 992a seems to be a good choice for a cam and springs only upgrade, or you can have a chat to Jason (greenfoam) and ask him nicely for the ideal cam specs if you feel like getting a custom grind . Either way you go (I'd say 992a may be cheaper) Jason will be able to help you out for a tune I'm sure.
dude your car is one noisey machine rattle rattle tic tac toe
