WTB. 550 injectors for a s4
 

my na keeps leaning out at high rpm so i need some 550 turbo injectors

can be used as long as thay work

I'm sure I have a set, but I'm also sure they been sitting in my garage for a while, so I would suggest sending them out to be cleaned reguardless. I'll go see if I can find them, if so, $20.00 ea. + shipping. PM me if your interested.

I don't think that's the fix you are looking for. There will be extra fuel across the entire rpm range especially at idle. 550s aren't necessary on a stock n/a motor. What do you mean by going lean??

fix the problem, don't cover it up.

for the secondary i go lean after 5ooo rpm to lean for for confort low end is fine and runs smooth not stock emiss gone and i put new extust &cold air intake

Personally I've had two rx7s (one s4 and one s5) with no emissions AND exhaust and they were fine... even with the 6 ports removed on the s5. You don't have the airflow to need 550s even in the secondaries. It's just not necessary. Fix the REASON you are going "lean".

BTW, have you taken an english class in your life? Punctuation and complete sentences man!!;)
