>From what I've come to understand, the stock pump is good for high flow, not high pressure. So if you are using just a rising rate regulator, after 6 lbs of boost and what ever pressure is required to run the stock injectors at that level, the pump will be ok. Go beyond that and you're asking for trouble.
If you get bigger injectors, I understand it's good for beyond 200hp. David Moore was running 11lbs of boost with stock pump using 440cc injectors. Doug '90 CRX Si Now fortified with 9lbs of JR Supercharged boost. And a still not broke in 62k miles. ----- Original Message ----- From: "George Freeman" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> Sent: Sunday, June 02, 2002 11:57 AM Subject: CRX: RE: Fuel pump replacement..... > I was told by my (expert) mechanic Erik Coxe that the stock fuel pump on our > Hondas is good for up to 200hp engines.
