Aftermarket fuelrail? Is this really ness?

The 1000cc injectors I was clear about aswell as Hondata kpro being the only possible management system i know of. (They don't even know if they support the european version yet tho) I asked on their application forums.

On the older car i had the aem ems which i can not use anymore, and i did have the walbro 255 in the tank, which was enough for the 325whp on E85.
Had the tune at 350whp even but took it back due to high injector dutycycle. (750cc siemens deka) So the walbro might be enought for the 350 aswell, guessing at the limit. I do not intend to get more than ~350whp anyway. I'm happy with that region.
365x1,3 ~ 475

I used a good aftermarket FPR that i replaced the stock with. (stock one was located on the rail on the 2005 model) Worked wonders, adjustable pressure. I used it at 58psi (4bar) to get some more juice from the injectors. Boosted somewhere between 9 and 10psi.

I did drill in my old stock rail to install fuel pressure sensor, so modifying the stock one with a hole for return is not a problem.

So if i read you right, your saying that with thicker feedlines, the walbro 255 should be a safe bet? together with the aftermarket fpr.






Are you meaning that both the feedline and returnline shall pass the FPR? I don't get that. On the old setup the FPR was on the returnline and the installation were accurate with the red line going around the FPR on the feedside. Only fuel in and fuel out together with the hose from the intake were connected to the FPR.

This whole thing confuses me abit.
