Honda Fuel-Pressure Regulator Mod
Saw this in the tech section of a Magazine and wondering if people has tried it?
Honda Fuel-Pressure Regulator Mod
The stock Honda FPR is restrictive when the time comes to extract more performance from the engine. The restriction is in the return orifice. This problem can be solved if u drill a 0.35inch hole slightly angled toward the return port of the regulator. This mod helps alleviate some of the pressure caused by the restriction at lower RMP.
Anyone ever tried this? does it work?

Sounds interesting. I am a little confused about something though. Do you have to install an aftermarke fuel pressure regulator too?

Gains??? From reduced fuel pressure?
This mod is intended to relieve fuel pressure at idle when using 450cc injectors on a turbo'd motor. Keeps your motor from getting "flooded" at idle.

Re: Honda Fuel-Pressure Regulator Mod (civic-4-ges)
Its intended to relieve pressure if you upgrade your fuel system. If you get bigger injectors and a bigger fuel pump, your fuel pressure will go up. Mine went up from a stock pressure at about 30psi to 50psi. If you drill the hole as shown in the link I posted, it relieves pressure thus lowering your fuel pressure.
