450's are rather shitty injectors, they are old, never flow good, but 250whp on a bone stock d15 will not be obtained with 450's, 250whp can be obtained on a gsr with 450's, when we tuned a stock b16 with a gt35 turbo we needed to use 660's, 450s wouldnt even do, and we got that to 324whp on a dynojet. Depends how you wanna rev it too.
