mine runs just fine with a walbro 255lph and stock fpr. no change in driveability or mpg. it may be overkill for n/a applications but i had plans at the time.
Ressurection! Ha, ha! Did you ever install this? What was the result? Curious minds want to know.honkeybizkit said:Does anyone know what the stock fuel pump is rated at?
I used a old formula to figure out fuel pump size based on horsepower and made a guestimate of the fuel pump to be in the area of 100lph. I searched on here for a while and couldnt find any specs. I figured the stock pump was good untill about 270 hp.
The reason i ask is because I think the pump in my car is not all that great, but I dont want to shell out 200 dollars for a stocker. I like the price for a Walbro, but 255lph is way overkill for my All-Motor set-up. I figure I can just get the 190lph, but worried that even the 190 will bump my fuel pressure with the added flow. I have no intention of getting a nismo (or any other brand for that matter) regulator.
If anyone has any idea on the stock fuel pump rating, please chime in, or if anyone has a 190lph Walbro in an All Motor Sr20, please let me know if you have the stock regulator and if your fuel pressure rose after the install.
