i had granatelli motorsports pump on my blown b16, worked great it was an equivalent to a 190. i use the 255, but depending on what kind of management you are using.

if using a vafc i say stick to the stocker, cause with the flow of an upgreaded pump and the limitations of a vafc you will have an assload of fuel at an idle, and all the negative timing effects of a vafc which is bad.

if using crome/hondata i say go with a larger pump because you can really get into controlling the fuel well, also i suggest a FPR not just a riser, but something that can actually lower and raise the pressure, my car seemed to need a slightly lower fuel pressure than what it was at compared to stock, dont know why tho
