Hey, I always hear everybody talking about how the SR20DET is such a perfect 50/50 weight ratio distribution. What about the KA shouldn't it be just as close or does the iron block make that much a difference.

the nissan 240sx weight distribution is 53/47 front to rear. yes the sr20det swap will get it to about 50/50 because the sr is a smaller motor and it has an alumimun block, the ka is iron
