I hear there is up to 3 tenths difference between a good Iame x30 and a bad one.
Is this true in your opinions, if so is there anything that can be changed in the engine to make a bad x30 better.
What sort of things can be altered on an x30 to make a engine faster?
Are after market parts allowed to be used in an x30 ie: Main bearings , seals ,pistons etc.
Does bore size make any difference.
Has anybody had evidence of noticeable difference on a Dyno or on a track to show this.
looking forward to hear some comments on this topic.
