Re: what fuel pump and fuel injectors ?
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.

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

Re: what fuel pump and fuel injectors ?
This post really helps

As an example, someone put down 203/156(stock EX Pump 79lph, 310cc)
and 214/153 (Stock Dx Pump 79lph, 310cc)
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.

Re: what fuel pump and fuel injectors ?
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.

Re: what fuel pump and fuel injectors ?
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.
