guys i have to agree with all of you. i am interested in building an all round fast car, not just a drag car, a good friend of mine has got a ca powered datsun 1200 ute, it's a weapon, but without the lsd and appropriate rubber/suspension it is a very dangerous car. tap the gas and it steps out even in a straight line, he's the first to tell you this. I can imagine by putting in a bigger engine you would only be making the car even more unpredictable. i've decided to do the Ca conversion, i'm going to fully upgrade the suspension all round and put in a Hi-Lux lsd. this should make for a fast straight line and cornering vehicle. haha i won't be doing this for a while but i'm about to start collecting all the parts i'll need. starting with that diff ofcourse the whole conversion will be documented and because it's a car it won't go smoothly and it'll take ages but hey isn't that the whole point of having a project.
