well if u want d series and hp all motor is not the place for it Bisimoto is the SOHC man and he holds all motor record in a D at 220ish so i doubt u want to throw his kinda money down for a allmotor

my motor setup is less than 1k for (boost)

9.0:1 JE forged pistons, fresh machining, Eagle H beam rods, micro polish crank,new honda seals, gaskets, and timing belt -- and will be good for 300hp ALL day granted that does not include my head work i am having done, cam, and so on and turbo kit
