Also what are the differences between the red top and black top. I already know the years and models they came with, blacks will usually have less miles etc... But are there any other real differences? I heard something about the intake setup on the engine being a bit different and its better on the red top if your going to make serious HP. Are the Pistons and compression ratios all the same?

there are no differences between the S13 Redtop and the S13 Blacktop. If your talking about the S14 Blacktop then yes it is different in that it had 217hp compared to 202hp. the S14 blacktop had a larger turbo on it so if you planned on maxing out the stock turbo then the S14 blacktop can be made to push out more hp then an S13 black top could. Yes the pistons and the compression ratios are the same for the S13 SR's
