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?

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.
