I recently ordered a new 255 Walbro fuel pump (gss342).
Question, will I need new/larger injectors?

 

nope!

 

you will need bigger injectors when you get near 360whp.

 

Stock injectors are fine for lots of mods. Look at my list and I am still using the 550's

 

thanks guys!

anyways, how many horse power can 255 fuel pump support? is that nessceary to rebulit fuel line if upgrade the turbo( such as r35 or rx6)? does any body here rebuild his fuel line? thankx

 

I have 660s im making good power with what i have below. Its not ness. and alot of people will tell you not to do it but you can get a afc and injectors and get it tuned right and its pretty bad a$$ no one around here can hang with me. Just me 02 but you will spend some money on gas!
