Awesome guys, thanks, this was the point of this thread. Now, why is it no one here seems the RB25 is a good choice over the SR for an S13? Simply because of weight? If so, how much of a weight difference is it? I would like to make 400-450 to the wheels, so it seemed a better idea to go with the RB so I could run the stock internals for a while. However, if the SR is that much lighter than the RB I will stick with that because I don't really like drag racing.... Thanks for all the input 
Secret Services routinely makes 400-450 to the wheels on stock sr20dets
