Hi Guys,

I was just wondering if the stock fuel pump that use to power my old D15 motor in my 1993 EG Civic would need to be replaced because of the H22A thats in the EG now?

Also, the pump is the old original that came with the car and do guys think it would be advisable to replace it right now or not? Thanks.

 

you should definitely change out the pump. a gsr or a walbro pump would do you right. i think the injectors on the h22 are 260cc? the d-series are only 240cc. it is worth spending the extra hundred bucks instead of hurting your new motor. i have an itr pump that i retro fitted to my 92 eg housing. let me know if you are intersted in buying it. it works great and is a complete drop in.

 

^^^^wow what a horribly wrong informed person. your stock pump will be fine. but if you want insurance put in a walbro.

 

stock pump is fine.

 

H22 injectors are 310 if im not wrong

 

OBD1 is 345cc peak and hold, OBD2 is 290cc saturated.

 

ran mine on the stock pump with no problems. Just swapped over to a s2000 pump not long ago only for the reson of my old pump going up and I could get the s2000 pump for $20 lol

 

Damn this is gettin confusing - firstly, my motor is a JDM H22A OBD1 - so do I have to change the pump? Thanks!

 

What are you confused with? Either the current pump/ fuel system is ok or its not ok. If you've got the time and money its up to you if you want to upgrade the fuel system.

Test the pressure at the rail, refer to the prelude specs and determain if its sufficient.

 

Well I decided to go with a Walboro Pump and a B&M FPR with the built in gauge - that should be a nice upgrade, and if I decide to boost later I can always get my tuner to change the FPR, since it will already be adjustable - good choice don't you think??

If you're definately going to upgrade I suppose it's easier to do it now. It'll run just fine on the stock pump. Plenty of people around here run the stock one, including myself, without any problems.

 

Chem Geek I pm'd you - need to ask u about ur car!

oh please. sell your "ITR" stuff on ebay.

I cant see any reason why the stock pump wouldnt work. tuning the car with a wideband (which you should do) and a fuel pressure gauge will ultimately tell you if you need need a bigger pump.

If you do decide to go with a walbro (which flows A LOT more) make sure you buy a fuel pressure regulator so that you can keep the fuel pressure to spec. a cheap B&M FPR works perfectly fine.

I suggest you do this as well. --&gt; http://www.theoldone.com/articles/regulator/

good luck.

 

Hey man, I ran my 92 Civic DX with the original stock Honda Civic fuel pump from my D15B7 with my JDM H22A with no problems at all.

I'd just suggest sticking with the stock one. It's efficient enough to handle a stock H22A motor and it's also probably more reliable than an aftermarket one.
