I need to get bigger injectors. I'm runing denso 720cc injectors. But i have rc 1000cc injectors just laying around.

i have read the old style bosch injectors like (RC. denso, PTE FIC blue max) do not idel well when the injectors are big like 1000cc to 1600cc

i have read that the newer high impeadeancy/saturated injectors (ID/FIC 1000cc and 2000cc) are much better and ideal better


is this true?
Why is it true?
Should i slap on my rc1000cc or sell them and buy some id/fic 1000cc saturated injectors and remove the stock resistor box?

Yes, avoid the ID1000s though.

Bigger injectors can idle fine....its all in who is scaling them. You can get 2150's to idle like 720's.

No, the OP was correct. The big Bosch hi impedance injectors can idle and handle low IPW like stock. Really no reason for small injectors anymore.

However, the older low impedance big injectors are really nasty to tune at idle and low IPW, the best tuners in the world will tell you the same.

That may have been what you meant but it is important to clarify as that was his question.

the older style bosch 1600cc's are junk but anything under that usually is ok. like your RCs will work out fine.

Yes that was my questions. I read that the old style Bosch low impeadeance peak and hold injectors like the rc/pte 1000cc-16000cc injectors are hard to tune and idle poorly. Thus making the car drive not so good

The new saturated high impedece big injectors like the fix/id 1000cc and 2000cc are suppose to work like stock.

Is this correct?
Does this mean the old style large peak and hold injectors are obsolete and should not be purchased any more?
Should I sell my rc 1000cc for high impedeancy 1000cc injectors? Will my car run better with the high impedance 1000cc injectors?

Your car will run fine with the RC 1000s... however I prefer a high z injector now that I have personnaly used the ID1000s, FIC highz 1100s and the high z 2000cc. It is newer technology, and that generally tends to be better than older tech...
