there is alot of potential in those motors. What I posted is just a compilation of all sorts of different facts ive gathered over the years and its simply the basics. theres more than you can imagine as to what you can do with a D series. Most people do the two simple ways to make power .. boost... or swap.

something else is if you do build the D up the D produces more torque than a stock B (Si or GSR) so you have a little bit of an advantage there. but no matter what you do it will cost money so you need to either save for the whole thing at once or build it right, in stages the first time.
