i own a 92 civic hatch cx, i have a 95 LS motor in it, i heard that the fuel pump from the 1.5 liter (stock fuel pump) does not flow enough and to replace with integra fuel pump. who has done this or knows anything about what i am talking about please let me know

 

i have a 92 civic hatch SI and i have a 98 prelude fuel pump in there and it works and bolts right up...

 

i know it bolts up, but is there a difference

 

92-95 civic Si,EX have 240cc injectors,94-00 integra LS,Gsr,Type R have 240cc injectors...ok i might be wrong on this one but lets see...93-96 H22a prelude have 290cc injectors.97 up H22a have 310cc injectors or maybe 290cc i dont know..but thats what i have a h22a pump

 

anybody have any other knowledge

 

If you have a b-series engine, it would be wise to have a b-series fuel pump. All b-series fuel pumps flow the same except for the GSR and ITR which flow a little more. I drove around for a couple weeks with my stock cx fuel pump after I got my swap done and it felt weak when I hit vtec. I was afraid of detonation so I got an ITR fuel pump from Jerome @ sohfast. After installation, vtec threw me in the backseat.

 

ITR/GS-R = 131 Liters / hour
all the rest = 79 liters / hour

upgrade the pump.

 

do i need to replace mine i have a 95 ex and i just swap a b16a2 you think i need to change as well.

 

I called a while back to verify that the various fuel pumps were different and YES they are.

1992-1995 Civic Si/EX fuel pump is a different part number from the lower models.
1994-2001 Integra GS-R/Type R are the same pump and are more costly than the lower models as well.

It's not a bad idea to upgrade to somehting at least like an Si/EX one or something.

 

i have a 93 cx and i want to h22a swap it i know you have to change fuel pump but do you have to change the fuel lines too?

 

Go to a local salvage and get yourself a 1st gen Turbo elcipse pump. Direct bolt in and more fuel then an ITR pump. I paid $50 for mine.

 

If you get a 96-up ITR or GSR fuel pump, it will bolt in with no modifications. All you have to do is switch the placement of both tubes because from 96-up, the air tube and gas tube are in opposite places from the pre 96.

JOEBLAZE78: You do not HAVE to replace the fuel pump since you have an EX model, yours should be sufficient until you start modding your engine heavily, FI or Nitrous.

Bought mine there. Excellent, flow from 5500 k to redline. You "CAN" feel the difference. 255lph

My setup is B18C1 in CX.

 

Hmmm..my car seems to run fine

 

I would like to know also, I have a b18c1 in my 96 ex, if uprgrading it to a gsr or typer makes that much of a difference, I will purchase one! More info please, bump!

 

Anybody else that can varify this? If it is, then i you Doctor CorteZ ...

 

MIne ran fine with CX pump too. But its better with my 255lph Walbro. Just my opinion.

 

i got a 99 gsr fuel pump today, did anybody verify on how much they flow

 

mine felt WAY better going from a cx pump to a Walbro 255 lph pump on the CRVTEC.
