Hi, have someone please experience with High impendance injectors for R33 RB26? I want use on for my project Racelogic traction control, and this working just with Hi impendance injectors. From start I need same size like OEM (440?), later, after one good seazon i want go with power higher and buy bigger.

Problem is, i have tunned ECU ( original for my engine ) from JPN for OEM injectors and i dont want buy now Stand allone ECU.

I need to find injectors with same size like OEM for my ECU.

Next question ist, which Fuel Rail? Thanks Mirek

We use the Bosch 440cc high impedance injector (Solid green in colour)
They come with a 14mm top O-ring, but can be machined down to 10.5mm (standard fuel rail) or 11mm (after market HKS/Tomei and knock-off rails) due to the thickness of the standard 14mm O-ring you use two O-rings to fill up the gap. Works very well.
The plugs are also the same.

From there you can go to a Siemens 666cc and do the same thing, but Bosch make an awesome 040 1000cc injector now that uses different sized top and bottom adaptors to suit most any car.
