if i put NOS on my lsvtec civic, would i need larger injectors and would i need to upgrade or change my ecu in any way???

 

depends on the shot, most times no. and the stock ecu can not control larger injectors

and you just made a thread asking the same question like an hour ago.......

Since your in Suffolk county, take a ride down to Bayshore and talk to the guys at NRG Tech. I was there yesterday and they were installing a kit on a K20

Here's the web site or call the shop

P.S. BBQ this sunday!!

 

you dont need to do anything to your fuel injectors or your ecu........some people dont seem to get this, but the instructions really do work.

good luck.
