I did a b16 swap and I am running lean somewhat , just curious if anyone else has came across this problem??

 

yes your stock fuel pump cant handle the up in fuel from stock to b16

 

i have a stock fuel pump with an adjustable fpr and its doing fine

 

i currently have a 1990 Civic Si Hatchback with stock b16 (5 million series) with a the stock 1990 Civic Si hatchback fuel pump, what should i look for to get or am i ok?

 

well from my experience they don't hold up i change my motor to a zc with rail injectors and fpr with other mods to support and my pump failed out after 25 miles get a walbro 255 should hold up pretty well
now going lsvtec turbo with 1000cc sat injectors will need different again

 

I was running a 220whp K20 with the stock fuel pump and didnt have any problems with it for 10k km

 

yeah stock fuel pump is plenty..if you want to do an upgrade dont get that walbro junk (no offense)..get a dohc vtec pump from a gsr or type-r,99-00 si,etc..they flow almost twice then the others do ...134lph vs. 79 lph

note- it has to be rigged to fit into our tanks ...but maybe the 92-93 gsr fits perfect,,not really sure

 

So if i get a differnt fuel pump, could i just put it on and call it a day or will i have t be doing some adjusting with my fuel?

what fuel pump do you have in mind? Some need adjustable fuel pressure regulators to get it back to stock fuel pressure

 

Well, anything besides stock. Since i prolly dont get fuel i actually need. i'm going to have to test my fuel psi. what psi am i suppose to have?

wit the vacuum hose off its ~ 38-40 on mine and i think all hondas,,, but the book has it something like 36-40 psi with the vacuum off ,,

 

I'll have to look. cause i have a b16 in my complete 90 civic si, and it's not running the way it should be, atleast i think so...

 

got any codes? whats it doing?

 

Well, let's start off with. i have no o2 sensors connected and i'm not getting any codes. i smell like odor of gas fumes and i dont know where to start looking for the leak. my gas mpg is not very great.

 

Stock pumps are fine untill you get over 300hp. I thought I was having problems with my pump on my K20, but it turned out it was my filter clogging. Car sat for 3 years so I'm sure there was a little bit of crap in there. Cleaned out the element and flows great now. I did allready replace the pump with a walbro 255 hp, so now I'm good for cams, bigger injectors, and a full on IPS setup. Check your filter. If you do need a pump you can buy walbro 255's all day long on ebay for $99 shipped.

what do you mean theres no codes? you mean the check engine light isnt on or the bulb on the ecu isnt blinking...Cause my check engine light bulb was missing when i 1st bought the car and it had me stumped...Having no o2 sensors connected will definenatly make the car run like **** and pig rich...

 

Check engine light works, because my distributer recently gave out and it was throwing a code for that, i tried other stock unchipped ecu's and stil no check engine light or cel codes from the ecu.

 

alright thanks....
