Ok Ive heard that it's a good idea to get a GSR fuel pump when you swap a B18C into a 5th gen civic so I was thinking about doing so but I dont know if i need the extra fuel with the minimal mods Ive done. List:

1992 Dx Hatch, 1995 JDM GSR engine with LSD
I, 4-2-1 H, custom 2.25" E
Jun flywheel, 6 puck clutch

Thats all ive really done performance wise. Should I invest in a stock GSR fuel pump or maybe a 255lph one? thanks!

One, you have a good engine in your chasis. Now you need guages to monitor the system unless you don't mind risking loosing that engine.....guages can be hidden so you don't get accused of being "ricey". Get the fuel pressure guage and monitor the fuel pressure, if it is below the requried then you need a bigger fuel pump if it is okay then there is no need......I am thinking that if you plan on modifing the engine more than you will need a larger fuel pump but if you stay where you are the civic pump is okay.

 

what are other precautionary gauges? AF ratio? Fuel Pressure? what else? Ive never been a big gague fan but i guess it does make sense so i dont blow my baby up.
