Message: <blockquote data-quote="shiroitenshi" data-source="post: 1719837" data-attributes="member: 27518">Thing is, fuel pumps is said to be similar across all honda makes of the B-series. H-series, I don't really know.. because nobody here owns a modded prelude.. at least not one that knows about engine stuff.Oh.. I think you misinterpreted what I said J101. I didn't test the H22A fuel pressure regulator on a H22A car, but rather on my own B16A civic with the stock fuel pump. so all numbers were from the same fuel system, the only change being the fuel regulator.It could be that the stock fuel pump on the H22A pushes more pressure, hence the regulator body could be made smaller and the intake port hole could be made bigger (inside the regulator, as the outer port could be made visually similar for hose fitting purposes) and yet be able to make adequate pressure.I noticed this trend seems to apply on high capacity cars like the GTR, which has quite a small bodied after market fuel regulator, compare to the B-series aftermarket ones, which has are distinctly bigger (esp the aftermarket ones). I believe it's because the fuel pumps on these cars push out more pressure due to their high flow rate... hence the pressure regulators and stuff don't need high pressures like small cc modded engine.From what I know about fuel pressure regulators, The max pressure is determined by the spring rate, which is controlled by the vacuum line for idle and WOT, while the pressure at idle is dependent on the body of the fuel regulator, and it's intake port size inside the fuel regulator. On an adjustable one, I think the threaded vacuum port on the regulator is for adjusting the spring rate.Still, this is just theories at best for now. Must learn more.</blockquote>
