What shot do you recommend for a LS with I/E and a block guard?

 

i would not go more than 75. you should also upgrade your fuel. injectors, fmu, fuel pump.

 

i wouldnt even do a 75 shot without the proper fuel management.
Im running a 30 shot currently..worth it because it will take most cars around such as Civic SI's and Sentra SE-R's...and a 30 shot wont really wear out motor like a 75 shot would. i reccomend a 30 shot for daily use

 

i ran a 85 shot on a zex kit... its really just hit or miss w/ N20 man... also ur luck

 

What is a block guard? And would 50 shot be safe with just basic bolt-ons?
