what fuel pump should i use on my setup. i have a stock jdm itr engine w/ cam gears, jdm dc sports 4-1 header, apex'i n1 exhaust, aem fuel rail and a sard fpr. the car originally is an rs and it has about 100k on the chassis and i'm sure the fuel pump has never been changed out. i notice my car kinda lacking something so i'm gonna change this out just to see what happens. what should i get?

 

no need for anything better than stock. I haven't priced OEM ones but you may end up cheaper with an aftermarket one. Check on a Walbro 195 lph in tank and compare the price vs. OEM.

 

OEM should be fine. But like he said, look at a Walbro 195. You can get them as cheap as $75.

 

btw...

If your doing this just because your car feels "tired," I don't see the point. You may just be wasting your money. Check for the obvious first (compression test would be my first check).

 

tuneup time, and also change you fuel filter.

 

my compression is fine i just changed the head gasket out like a month ago. i'm using the stock head gasket and my compression was 250psi across the board. i'll check on that fuel pump and i think i'll just go ahead and get that tune up done. could that explain why i get such poor gas mileage. i get about 220 gallons to the tank. w/ today's gas prices that sucks.

 

What's your fuel pressure at? It sounds like you may be running really rich and that could be killing your power

 

check the voltage on the fuel pump, requires taking out the rear seats though

 

if the fuel pump has never been changed from an RS that means you only have a 79lph pump. the itr's come stock with a 135lph pump. just get a walbro 255lph, you can get them for $80 and if you ever decide to go boost or nitrous or anything you already have it.

 

fuel filters that are bad kill performance

 

what's the stock lph rating for an itr? because i was reading another post and someone said don't bother getting an upgraded fuel pump unless you plan on going fi.

I just said the itr is a 135 lph pump just like all the other DOHC VTEC. The SOHC and DOHC nonVTEC are 79lph. You should bother to upgrade. And also why bother with a 195 lph pump when you could get the 255lph for almost the same price and that way if you ever go boost or nitrous, you have it.
