i own a vx hatch with a b18c swap usual bolt ons but my edlebrock manifold was coming in contact with the b18c factory fuel pressure regulator so i installed an ls regulator with the bend in it is that switch hurting my performance, basically what i'm asking is are both regulators the same pressure? and should i put the gsr regulator on?

 

Not sure about the Edelbrock interference and how much clearance u have... but go B&M.... for $40 u can adjust it youself, with a guage of course. But adjust it, then take the guage off cuz it will break before u need it under the hood again

 

B&M is garbage. Not only do you have to hack up your stock FPR, but you also can't decrease the pressure like you can with the other FPRs.

 

I've gone AEM, and haven't had any problems. I'm boosting, so it's perfect. It is a little pricey though, but you get what you pay for. Strut bar clearance issues though...
