If you're using the stock turbo, 690's should be fine as long as you're using TII (550cc) primaries. With the N/A primaries you may be cutting it close...I wouldn't do it without a wideband bc I have no experience with that combo. Are you going to have something to control these injectors?

 

stock s4 turbo(ported to hell),550 primaries,safcII,wb..... i found the 690's for 100 bucks cleaned thats why im asking.

 

sounds like it should be fine to me. I'm not a pro on NA turbos though.

 

What did I tell you in PMs? The answer is NO. Yes, I ran less fuel, but then I was also dangerously lean. I recommend minimum of 720 CC sec/ 550cc pri in all turbo-NA application. Gives you wiggle room.

If you're just going to ask the same question again, don't bother PM'ing me.

 

no offense, youve been a huge help! im sorry,did'nt mean for the insult i pm'ed you yesterday and thought you werent going to answer as some people do,so i just asked other people, i dont wanna get on wrong terms.
