I'm sure this has been discussed before but most the threads I read about it just had ppl that "think" they knew the limits but had never pushed their car too it or had much proof to back up their claims so I'm hoping someone with experience could help me out I'm working on a turbo lq4 fbody gonna just be a street feeling hurter looking at making prob 600-700whp but would like to be able to turn it up to like 800 and be fine so will stock lines or rail work or just go completely aftermarket? Just like to save money for more important things if it's not needed
