Youre wrong Just messing.... the B-series engines are a little heavier than your stock d-series, between 70-100lbs, which might contribute to a little bit of understeer, but it would probably barely be noticable, if at all. The difference in weight between a b16 a b18 and a b20 is neglegable, probably less than 30 lbs. To put that in perspective, all your A/C components weigh about 60lbs. Its not until you throw in something huge, like a H-series (almost 200lbs more than your stock engine) that you start to have serious understeer problems.:thumbup:
