On the Z20LEH engine, LPG conversions can produce higher BHP figures than standard petrol ones.
Very true, LPG has an octane rating of 110!
so more boost can be used before problems occur
Also lpg is a liquid, as it transforms into a gas it absorbs heat from the surrounding air effectivly cooling the air/making it more dense.
But Petrol has approx 23% more energy per litre. So more lpg is needed to do the same amount of work.

If i could, i would fit a lpg kit to my car.
If i had a tuned f.i.............it would be a MUST!
