| : Reasons: : 1)Why pay for injectors twice over?
 : 2)They cost about the same regardless of cc size.
 : 3)Used 550's with no warranty will not sell for very much money.
 : 4)If you tune your AFC correctly your milage should be about the same.
 : 5)Finally, when you do upgrade your turbos (because you will eventually), hit 550rwhp, and max out your injectors you will wish that you had bought the 740's.
 : : I have a 95TT so i have the option of getting the Nismo in either 555 or 740cc. I am currently an SGP stage 7 without NOS (waiting on SteamyZ). I have no plans to go to bigger turbos in the near future (the car will be in storage for a year) and the only other thing i plan to do before that is dual POP. I do not plan to do any internal engine work at this time either.
 : : I have an AFC to tune with and will of course be getting the upgraded JWT chip.
 : : Should i just get the 555 since the car is a daily driver and i don't need serious headaches messing with it running wierd? : : Should i go ahead and get the 740's knowing that they will support whatever build up i plan to do after i get the car out of storage?  : : Any reccomendations, opinions and experiences are gratefully appreciated. thanks for looking.
