External fuel pump regulator mazda 3 sport 2.3L
 

Hi, I recently joined the forum and I liked it a lot, I hope you advise me.
Well the sutuation is like this .... I have a mazda 3 that I have made certain variations; I would like you to help me if possible with the project since it was not going to be like that at the beginning but in the end ... well you know, you want to get a little more performance.
Well, what is varied is mostly the pistons in overbore, with wiseco rings and in high compression 12.5: 1 (I prefer that to turbo) and set the original compu with the mazda edit software in summary in what is more relevant
Now, as every variation has been giving me problems of knock and force, the knock is corrected with the mazda edit to draw the time a little, more than I remain with high compression but right now it seems to me that the pump is failing; no more preamble but just as important with the info I give them; What do you think of putting an external regulator, but I think adding some 550 cc injectors, I already have the pump that fits in the 2005 mazda system that I have, she uses 265 LPH, a DWR1000.
So I think no one has done it in Latin America but I think that someone in the USA is as crazy as me ... jajjaa :) is a joke but if there are more facilities than here it seems to me.
Thanks in advance and any clarification thank you.
