Hi, i got a 88 10th, bought a 91 JDM 13B-T and put it in, i bought 720cc nipondenso secondaries, now i was told i need to wire in 10watt 10ohm resistors inline for every non-stock injector i have, now im not sure if i wire them in series or in parallel?
also, i got my fuel rail bored out by i believe SR motorsports(was awhile ago) and the injectors fit nicely up in there, but the bottom o-ring on the injector doesn't fit down into the block (believe there called injector seals, forget exactly) very well, was wondering if anyone has done this and if i just need new o-rings or what, thanks.

each injector in series with a single resister for each injector.

But why are you using resistors, were the 720cc the wrong resistance? You do know that the 91 and the 88 13BT use the same resistance injectors right?

really? i was told that they wheren't the same resistance and that i needed 10watt 10ohm resistors... but if they arent needed then thats good.

Icemark

only the 86-87 needed the resistors

HAILERS

The question in my mind is: are the 720's high or low impedence??/ Low resistance of about 2.5 ohms or somewhere around 10-12 ohms?? You need to take a look.

The 720's are low impediance, and the car is high, so i do need the resistors, atleast thats what the tech told me who sold me the injectors, correct me if im wrong though, would like a 3rd opinion, not that i am doubting ur word mark just would like it, thnx.
