Tuning Guide: Injectors

It is possible to use aftermarket injectors with the PowerFC, as long as there is a resistor pack installed if using low impedence injectors.

FAILURE to utilise a resistor pack with low impedence injectors will result in injector driver circuit failure.

Equivalent: Apexi / HKS / Nismo / Tomei

JECS produces injectors for well-known aftermarket brands like Nismo, HKS, Tomei and Apexi and can be considered equivalent:

Injector	Feed	Imp	Color	Shape	Apexi	HKS	Nismo	Tomei	Engine
JECS 480 cc	Top	High	Purple	Circle	-	1402-RN011	16600-RR710	-	RB25 (neo)
JECS 555 cc	Side	High	Yellow	Circle	404-N004	1402-RN008	16600-RR543	195012	SR20,RB25
JECS 600 cc	Top	Low	Purple	Rect	404-N003	1402-RN010	16600-RRR60	195015	RB20,RB26
JECS 740 cc	Side	High	Red	Circle	404-N006	1402-RN009	16600-RR544	195017	SR20,RB25

Even though HKS sources injectors from JECS, HKS do modifications to the injectors to improve overall performance / characteristics.

Denso injectors are also produced for SARD and Blitz.
