In that post you kinda go both ways. First you say cars can make over 200whp on 79lph pumps. Then you say you usually recommend 190lph walbro units...

Maybe I shoiuld just get a used GSR pump and call it a day...

If you read the whole thread up to that post, you'll see I'm not going two different ways at all. My post was addressing two things, first, that a stock pump can handle most performance builds out there and doesn't need to be upgraded. Second, if the OP really insists on buying a high volume fuel pump, then 190lph would be my choice over the 255Lph and I stated why.

Gotcha...

Guess I'll keep it stock. Thanks for the help!

This post really helps

Fact: Liters to Cubic Centimeters: 1 L = 1000cc's

Example 79 lph pump = 79,000 cc's per hour

So, 79,000 cc's per hour divided by 60 minutes = 79,000/60 = 1316.66 cc's min

So, 1316.66 cc's min/4 injectors = 1316.66/4 = 329.16 cc's min

Which is plenty large enough to support a 310cc/min injector.

In turn that would indicate that an upgrade to the 135lph would be all that is needed in most cases for a healthy buffer of fuel volume.

Example: 135lph x 1000 = 135,000 cc's/hour

135,000/60(minutes in the hour) = 2250cc's/min

2250/4 injectors = 562.5 cc's/min (Would support 560cc 's per injector)

Basically for all intents and purposes I will only refer to the majority of modified Hondas/Acuras.

Fuel Pump Ratings are as follows:

1988-2000 Civic CX, DX, EX = 79 lph
1989-2001 Integra RS, GS, LS = 79 lph
1999-2000 Civic SI = 135 lph
1994-2001 Integra GSR = 135 lph
1997-2001 ITR = 135 lph


I have seen a few problems with all motor cars trying to turn down the fuel pressure when using a 255L pump and not getting it to where they need. I would also recomend the 190LPH pump.

1000/60 = 16.667

That'll help you skip a step.

Example > 320LPH * 16.667 = 5333.44 cc/min

Stock fuel pump is fine.

Go with RDX injectors, run them at 60 psi and control them with Hondata. The RDXs offer a better spray pattern, will support the biggest of NA builds, and have OEM reliability.

Depends on the fuel used.

500whp on gasoline > 255LPH DW200

500whp on E85 > 320LPH DW300

The DW200 should be all you'd need, then.

...and since it is a DD, you'll like how quiet our pump is.

Since we are in the All Motor forum, I'm assuming this is for a N/A build?

Gas or Ethanol? Base fuel pressure?

@ 40 psi, the DW200 flows 255LPH. That's enough to feed 1000cc injectors at 100% cycle and then some. 1000cc injectors will get you in the mid-600's on gas in a N/A application.
