does anyone know how many cc's a 1990 240sx ka24e fuel injectors and pump have?

i was going to buy new fuel injectors and fuel pump for my car but then i had the option of going to higher cc's. i wanted to buy walbro injectors and pump. my lowest option for the injectors was 370cc i read some articles and i think that's too high not sure though. and the lowest option for a fuel pump was 190. if you have any idea if i could use either one for my stock ka24e sohc motor please let me know my car has been running really crappy lately especially when i have to go far places or drive for a long time. i was told to replace the injectors and pump by a mechanic. also looked for some suggestions on the forums and that's the most likely place to start with the symptoms that my car has.

so please reply. thanks.

If you have alot of miles on your car I would replace the O2 sensor also.
